Bug Fixes
- 1.1a1 broke Akhet by not providing a backwards compatibility import shim
for ``pyramid.paster.PyramidTemplate``. Now one has been added, although a
deprecation warning is emitted when Akhet imports it.
- If multiple specs were provided in a single call to
``config.add_translation_dirs``, the directories were inserted into the
beginning of the directory list in the wrong order: they were inserted in
the reverse of the order they were provided in the ``*specs`` list (items
later in the list were added before ones earlier in the list). This is now
Backwards Incompatibilities
- The pyramid Router attempted to set a value into the key
``environ['repoze.bfg.message']`` when it caught a view-related exception
for backwards compatibility with applications written for ``repoze.bfg``
during error handling. It did this by using code that looked like so::
# "why" is an exception object
msg = why[0]
msg = ''
environ['repoze.bfg.message'] = msg
Use of the value ``environ['repoze.bfg.message']`` was docs-deprecated in
Pyramid 1.0. Our standing policy is to not remove features after a
deprecation for two full major releases, so this code was originally slated
to be removed in Pyramid 1.2. However, computing the
``repoze.bfg.message`` value was the source of at least one bug found in
the wild (, and there isn't a
foolproof way to both preserve backwards compatibility and to fix the bug.
Therefore, the code which sets the value has been removed in this release.
Code in exception views which relies on this value's presence in the
environment should now use the ``exception`` attribute of the request
(e.g. ``request.exception[0]``) to retrieve the message instead of relying
on ``request.environ['repoze.bfg.message']``.
1.1a1 (2011-06-20)
- The term "template" used to refer to both "paster templates" and "rendered
templates" (templates created by a rendering engine. i.e. Mako, Chameleon,
Jinja, etc.). "Paster templates" will now be refered to as "scaffolds",
whereas the name for "rendered templates" will remain as "templates."
- The ``wiki`` (ZODB+Traversal) tutorial was updated slightly.
- The ``wiki2`` (SQLA+URL Dispatch) tutorial was updated slightly.
- Make ``pyramid.interfaces.IAuthenticationPolicy`` and
``pyramid.interfaces.IAuthorizationPolicy`` public interfaces, and refer to
them within the ``pyramid.authentication`` and ``pyramid.authorization``
API docs.
- Render the function definitions for each exposed interface in
- Add missing docs reference to
``pyramid.config.Configurator.set_view_mapper`` and refer to it within
Hooks chapter section named "Using a View Mapper".
- Added section to the "Environment Variables and ``.ini`` File Settings"
chapter in the narrative documentation section entitled "Adding a Custom
- Added documentation for a "multidict" (e.g. the API of ``request.POST``) as
interface API documentation.
- Added a section to the "URL Dispatch" narrative chapter regarding the new
"static" route feature.
- Added "What's New in Pyramid 1.1" to HTML rendering of documentation.
- Added API docs for ``pyramid.authentication.SessionAuthenticationPolicy``.
- Added API docs for ``pyramid.httpexceptions.exception_response``.
- Added "HTTP Exceptions" section to Views narrative chapter including a
description of ``pyramid.httpexceptions.exception_response``.
- Add support for language fallbacks: when trying to translate for a
specific territory (such as ``en_GB``) fall back to translations
for the language (ie ``en``). This brings the translation behaviour in line
with GNU gettext and fixes partially translated texts when using C
- New authentication policy:
``pyramid.authentication.SessionAuthenticationPolicy``, which uses a session
to store credentials.
- Accessing the ``response`` attribute of a ``pyramid.request.Request``
object (e.g. ``request.response`` within a view) now produces a new
``pyramid.response.Response`` object. This feature is meant to be used
mainly when a view configured with a renderer needs to set response
attributes: all renderers will use the Response object implied by
``request.response`` as the response object returned to the router.
``request.response`` can also be used by code in a view that does not use a
renderer, however the response object that is produced by
``request.response`` must be returned when a renderer is not in play (it is
not a "global" response).
- Integers and longs passed as ``elements`` to ``pyramid.url.resource_url``
or ``pyramid.request.Request.resource_url`` e.g. ``resource_url(context,
request, 1, 2)`` (``1`` and ``2`` are the ``elements``) will now be
converted implicitly to strings in the result. Previously passing integers
or longs as elements would cause a TypeError.
- ``pyramid_alchemy`` paster template now uses ``query.get`` rather than
``query.filter_by`` to take better advantage of identity map caching.
- ``pyramid_alchemy`` paster template now has unit tests.
- Added ``pyramid.i18n.make_localizer`` API (broken out from
``get_localizer`` guts).
- An exception raised by a NewRequest event subscriber can now be caught by
an exception view.
- It is now possible to get information about why Pyramid raised a Forbidden
exception from within an exception view. The ``ACLDenied`` object returned
by the ``permits`` method of each stock authorization policy
(``pyramid.interfaces.IAuthorizationPolicy.permits``) is now attached to
the Forbidden exception as its ``result`` attribute. Therefore, if you've
created a Forbidden exception view, you can see the ACE, ACL, permission,
and principals involved in the request as
eg. ``context.result.permission``, ``context.result.acl``, etc within the
logic of the Forbidden exception view.
- Don't explicitly prevent the ``timeout`` from being lower than the
``reissue_time`` when setting up an ``AuthTktAuthenticationPolicy``
(previously such a configuration would raise a ``ValueError``, now it's
allowed, although typically nonsensical). Allowing the nonsensical
configuration made the code more understandable and required fewer tests.
- A new paster command named ``paster pviews`` was added. This command
prints a summary of potentially matching views for a given path. See the
section entitled "Displaying Matching Views for a Given URL" in the "View
Configuration" chapter of the narrative documentation for more information.
- The ``add_route`` method of the Configurator now accepts a ``static``
argument. If this argument is ``True``, the added route will never be
considered for matching when a request is handled. Instead, it will only
be useful for URL generation via ``route_url`` and ``route_path``. See the
section entitled "Static Routes" in the URL Dispatch narrative chapter for
more information.
- A default exception view for the context
``pyramid.interfaces.IExceptionResponse`` is now registered by default.
This means that an instance of any exception response class imported from
``pyramid.httpexceptions`` (such as ``HTTPFound``) can now be raised from
within view code; when raised, this exception view will render the
exception to a response.
- A function named ``pyramid.httpexceptions.exception_response`` is a
shortcut that can be used to create HTTP exception response objects using
an HTTP integer status code.
- The Configurator now accepts an additional keyword argument named
``exceptionresponse_view``. By default, this argument is populated with a
default exception view function that will be used when a response is raised
as an exception. When ``None`` is passed for this value, an exception view
for responses will not be registered. Passing ``None`` returns the
behavior of raising an HTTP exception to that of Pyramid 1.0 (the exception
will propagate to middleware and to the WSGI server).
- The ``pyramid.request.Request`` class now has a ``ResponseClass`` interface
which points at ``pyramid.response.Response``.
- The ``pyramid.response.Response`` class now has a ``RequestClass``
interface which points at ``pyramid.request.Request``.
- It is now possible to return an arbitrary object from a Pyramid view
callable even if a renderer is not used, as long as a suitable adapter to
``pyramid.interfaces.IResponse`` is registered for the type of the returned
object by using the new
``pyramid.config.Configurator.add_response_adapter`` API. See the section
in the Hooks chapter of the documentation entitled "Changing How Pyramid
Treats View Responses".
- The Pyramid router will now, by default, call the ``__call__`` method of
WebOb response objects when returning a WSGI response. This means that,
among other things, the ``conditional_response`` feature of WebOb response
objects will now behave properly.
- New method named ``pyramid.request.Request.is_response``. This method
should be used instead of the ``pyramid.view.is_response`` function, which
has been deprecated.
Bug Fixes
- URL pattern markers used in URL dispatch are permitted to specify a custom
regex. For example, the pattern ``/{foo:\d+}`` means to match ``/12345``
(foo==12345 in the match dictionary) but not ``/abc``. However, custom
regexes in a pattern marker which used squiggly brackets did not work. For
example, ``/{foo:\d{4}}`` would fail to match ``/1234`` and
``/{foo:\d{1,2}}`` would fail to match ``/1`` or ``/11``. One level of
inner squiggly brackets is now recognized so that the prior two patterns
given as examples now work. See also
- Don't send port numbers along with domain information in cookies set by
AuthTktCookieHelper (see
- ``pyramid.url.route_path`` (and the shortcut
``pyramid.request.Request.route_url`` method) now include the WSGI
SCRIPT_NAME at the front of the path if it is not empty (see
- ``pyramid.testing.DummyRequest`` now has a ``script_name`` attribute (the
empty string).
- Don't quote ``:@&+$,`` symbols in ``*elements`` passed to
``pyramid.url.route_url`` or ``pyramid.url.resource_url`` (see
- Include SCRIPT_NAME in redirects issued by
``pyramid.view.append_slash_notfound_view`` (see
- Static views registered with ``config.add_static_view`` which also included
a ``permission`` keyword argument would not work as expected, because
``add_static_view`` also registered a route factory internally. Because a
route factory was registered internally, the context checked by the Pyramid
permission machinery never had an ACL. ``add_static_view`` no longer
registers a route with a factory, so the default root factory will be used.
- ``config.add_static_view`` now passes extra keyword arguments it receives
to ``config.add_route`` (calling add_static_view is mostly logically
equivalent to adding a view of the type ``pyramid.static.static_view``
hooked up to a route with a subpath). This makes it possible to pass e.g.,
``factory=`` to ``add_static_view`` to protect a particular static view
with a custom ACL.
- ``testing.DummyRequest`` used the wrong registry (the global registry) as
``self.registry`` if a dummy request was created *before* ``testing.setUp``
was executed (``testing.setUp`` pushes a local registry onto the
threadlocal stack). Fixed by implementing ``registry`` as a property for
DummyRequest instead of eagerly assigning an attribute.

- When visiting a URL that represented a static view which resolved to a
subdirectory, the ``index.html`` of that subdirectory would not be served
properly. Instead, a redirect to ``/subdir`` would be issued. This has
been fixed, and now visiting a subdirectory that contains an ``index.html``
within a static view returns the index.html properly. See also
- Redirects issued by a static view did not take into account any existing
``SCRIPT_NAME`` (such as one set by a url mapping composite). Now they do.
- The ``pyramid.wsgi.wsgiapp2`` decorator did not take into account the
``SCRIPT_NAME`` in the origin request.
- The ``pyramid.wsgi.wsgiapp2`` decorator effectively only worked when it
decorated a view found via traversal; it ignored the ``PATH_INFO`` that was
part of a url-dispatch-matched view.
- Deprecated all assignments to ``request.response_*`` attributes (for
example ``request.response_content_type = 'foo'`` is now deprecated).
Assignments and mutations of assignable request attributes that were
considered by the framework for response influence are now deprecated:
``response_content_type``, ``response_headerlist``, ``response_status``,
``response_charset``, and ``response_cache_for``. Instead of assigning
these to the request object for later detection by the rendering machinery,
users should use the appropriate API of the Response object created by
accessing ``request.response`` (e.g. code which does
``request.response_content_type = 'abc'`` should be changed to
``request.response.content_type = 'abc'``).
- Passing view-related parameters to
``pyramid.config.Configurator.add_route`` is now deprecated. Previously, a
view was permitted to be connected to a route using a set of ``view*``
parameters passed to the ``add_route`` method of the Configurator. This
was a shorthand which replaced the need to perform a subsequent call to
``add_view``. For example, it was valid (and often recommended) to do::
config.add_route('home', '/', view='mypackage.views.myview',
Passing ``view*`` arguments to ``add_route`` is now deprecated in favor of
connecting a view to a predefined route via ``Configurator.add_view`` using
the route's ``route_name`` parameter. As a result, the above example
should now be spelled::
config.add_route('home', '/')
config.add_view('mypackage.views.myview', route_name='home')
This deprecation was done to reduce confusion observed in IRC, as well as
to (eventually) reduce documentation burden (see also A deprecation warning is
now issued when any view-related parameter is passed to
- Passing an ``environ`` dictionary to the ``__call__`` method of a
"traverser" (e.g. an object that implements
``pyramid.interfaces.ITraverser`` such as an instance of
``pyramid.traversal.ResourceTreeTraverser``) as its ``request`` argument
now causes a deprecation warning to be emitted. Consumer code should pass a
``request`` object instead. The fact that passing an environ dict is
permitted has been documentation-deprecated since ``repoze.bfg`` 1.1, and
this capability will be removed entirely in a future version.
- The following (undocumented, dictionary-like) methods of the
``pyramid.request.Request`` object have been deprecated: ``__contains__``,
``__delitem__``, ``__getitem__``, ``__iter__``, ``__setitem__``, ``get``,
``has_key``, ``items``, ``iteritems``, ``itervalues``, ``keys``, ``pop``,
``popitem``, ``setdefault``, ``update``, and ``values``. Usage of any of
these methods will cause a deprecation warning to be emitted. These
methods were added for internal compatibility in ``repoze.bfg`` 1.1 (code
that currently expects a request object expected an environ object in BFG
1.0 and before). In a future version, these methods will be removed
- Deprecated ``pyramid.view.is_response`` function in favor of (newly-added)
``pyramid.request.Request.is_response`` method. Determining if an object
is truly a valid response object now requires access to the registry, which
is only easily available as a request attribute. The
``pyramid.view.is_response`` function will still work until it is removed,
but now may return an incorrect answer under some (very uncommon)
Behavior Changes
- The default Mako renderer is now configured to escape all HTML in
expression tags. This is intended to help prevent XSS attacks caused by
rendering unsanitized input from users. To revert this behavior in user's
templates, they need to filter the expression through the 'n' filter.
For example, ${ myhtml | n }.
- A custom request factory is now required to return a request object that
has a ``response`` attribute (or "reified"/lazy property) if they the
request is meant to be used in a view that uses a renderer. This
``response`` attribute should be an instance of the class
- The JSON and string renderer factories now assign to
``request.response.content_type`` rather than
- Each built-in renderer factory now determines whether it should change the
content type of the response by comparing the response's content type
against the response's default content type; if the content type is the
default content type (usually ``text/html``), the renderer changes the
content type (to ``application/json`` or ``text/plain`` for JSON and string
renderers respectively).
- The ``pyramid.wsgi.wsgiapp2`` now uses a slightly different method of
figuring out how to "fix" ``SCRIPT_NAME`` and ``PATH_INFO`` for the
downstream application. As a result, those values may differ slightly from
the perspective of the downstream application (for example, ``SCRIPT_NAME``
will now never possess a trailing slash).
- Previously, ``pyramid.request.Request`` inherited from
``webob.request.Request`` and implemented ``__getattr__``, ``__setattr__``
and ``__delattr__`` itself in order to overidde "adhoc attr" WebOb behavior
where attributes of the request are stored in the environ. Now,
``pyramid.request.Request`` object inherits from (the more recent)
``webob.request.BaseRequest`` instead of ``webob.request.Request``, which
provides the same behavior. ``pyramid.request.Request`` no longer
implements its own ``__getattr__``, ``__setattr__`` or ``__delattr__`` as a
- ``pyramid.response.Response`` is now a *subclass* of
``webob.response.Response`` (in order to directly implement the
``pyramid.interfaces.IResponse`` interface).
- The "exception response" objects importable from ``pyramid.httpexceptions``
(e.g. ``HTTPNotFound``) are no longer just import aliases for classes that
actually live in ``webob.exc``. Instead, we've defined our own exception
classes within the module that mirror and emulate the ``webob.exc``
exception response objects almost entirely. See the "Design Defense" doc
section named "Pyramid Uses its Own HTTP Exception Classes" for more
Backwards Incompatibilities
- Pyramid no longer supports Python 2.4. Python 2.5 or better is required to
run Pyramid 1.1+.
- The Pyramid router now, by default, expects response objects returned from
view callables to implement the ``pyramid.interfaces.IResponse`` interface.
Unlike the Pyramid 1.0 version of this interface, objects which implement
IResponse now must define a ``__call__`` method that accepts ``environ``
and ``start_response``, and which returns an ``app_iter`` iterable, among
other things. Previously, it was possible to return any object which had
the three WebOb ``app_iter``, ``headerlist``, and ``status`` attributes as
a response, so this is a backwards incompatibility. It is possible to get
backwards compatibility back by registering an adapter to IResponse from
the type of object you're now returning from view callables. See the
section in the Hooks chapter of the documentation entitled "Changing How
Pyramid Treats View Responses".
- The ``pyramid.interfaces.IResponse`` interface is now much more extensive.
Previously it defined only ``app_iter``, ``status`` and ``headerlist``; now
it is basically intended to directly mirror the ``webob.Response`` API,
which has many methods and attributes.
- The ``pyramid.httpexceptions`` classes named ``HTTPFound``,
``HTTPMultipleChoices``, ``HTTPMovedPermanently``, ``HTTPSeeOther``,
``HTTPUseProxy``, and ``HTTPTemporaryRedirect`` now accept ``location`` as
their first positional argument rather than ``detail``. This means that
you can do, e.g. ``return pyramid.httpexceptions.HTTPFound('http://foo')``
rather than ``return
pyramid.httpexceptions.HTTPFound(location='http//foo')`` (the latter will
of course continue to work).
- Pyramid now depends on WebOb >= 1.0.2 as tests depend on the bugfix in that
release: "Fix handling of WSGI environs with missing ``SCRIPT_NAME``".
(Note that in reality, everyone should probably be using 1.0.4 or better
though, as WebOb 1.0.2 and 1.0.3 were effectively brownbag releases.)
1.0 (2011-01-30)
- Fixed bug in ZODB Wiki tutorial (missing dependency on ``docutils`` in
"models" step within ````).
- Removed API documentation for ``pyramid.testing`` APIs named
``registerDummySecurityPolicy``, ``registerResources``, ``registerModels``,
``registerEventListener``, ``registerTemplateRenderer``,
``registerDummyRenderer``, ``registerView``, ``registerUtility``,
``registerAdapter``, ``registerSubscriber``, ``registerRoute``,
and ``registerSettings``.
- Moved "Using ZODB With ZEO" and "Using repoze.catalog Within Pyramid"
tutorials out of core documentation and into the Pyramid Tutorials site
- Changed "Cleaning up After a Request" section in the URL Dispatch chapter
to use ``request.add_finished_callback`` instead of jamming an object with
a ``__del__`` into the WSGI environment.
- Remove duplication of ``add_route`` API documentation from URL Dispatch
narrative chapter.
- Remove duplication of API and narrative documentation in
``pyramid.view.view_config`` API docs by pointing to
``pyramid.config.add_view`` documentation and narrative chapter
- Removed some API documentation duplicated in narrative portions of
- Removed "Overall Flow of Authentication" from SQLAlchemy + URL Dispatch
wiki tutorial due to print space concerns (moved to Pyramid Tutorials
Bug Fixes
- Deprecated-since-BFG-1.2 APIs from ``pyramid.testing`` now properly emit
deprecation warnings.
- Added ``egg:repoze.retry#retry`` middleware to the WSGI pipeline in ZODB
templates (retry ZODB conflict errors which occur in normal operations).
- Removed duplicate implementations of ``is_response``. Two competing
implementations existed: one in ``pyramid.config`` and one in
``pyramid.view``. Now the one defined in ``pyramid.view`` is used
internally by ``pyramid.config`` and continues to be advertised as an API.
1.0b3 (2011-01-28)
Bug Fixes
- Use © instead of copyright symbol in paster templates / tutorial
templates for the benefit of folks who cutnpaste and save to a non-UTF8
- ``pyramid.view.append_slash_notfound_view`` now preserves GET query
parameters across redirects.
- Beef up documentation related to ``set_default_permission``: explicitly
mention that default permissions also protect exception views.
- Paster templates and tutorials now use spaces instead of tabs in their HTML
1.0b2 (2011-01-24)
Bug Fixes
- The ``production.ini`` generated by all paster templates now have an
effective logging level of WARN, which prevents e.g. SQLAlchemy statement
logging and other inappropriate output.
- The ``production.ini`` of the ``pyramid_routesalchemy`` and
``pyramid_alchemy`` paster templates did not have a ``sqlalchemy`` logger
section, preventing ``paster serve production.ini`` from working.
- The ``pyramid_routesalchemy`` and ``pyramid_alchemy`` paster templates used
the ``{{package}}`` variable in a place where it should have used the
``{{project}}`` variable, causing applications created with uppercase
letters e.g. ``paster create -t pyramid_routesalchemy Dibbus`` to fail to
start when ``paster serve development.ini`` was used against the result.
- The ``render_view`` method of ``pyramid.renderers.RendererHelper`` passed
an incorrect value into the renderer for ``renderer_info``. It now passes
an instance of ``RendererHelper`` instead of a dictionary, which is
consistent with other usages. See
- A bug existed in the ``pyramid.authentication.AuthTktCookieHelper`` which
would break any usage of an AuthTktAuthenticationPolicy when one was
configured to reissue its tokens (``reissue_time`` < ``timeout`` /
``max_age``). Symptom: ``ValueError: ('Invalid token %r', '')``. See
1.0b1 (2011-01-21)
- The AuthTktAuthenticationPolicy now accepts a ``tokens`` parameter via
````. The value must be a sequence of strings.
Tokens are placed into the auth_tkt "tokens" field and returned in the
auth_tkt cookie.
- Add ``wild_domain`` argument to AuthTktAuthenticationPolicy, which defaults
to ``True``. If it is set to ``False``, the feature of the policy which
sets a cookie with a wilcard domain will be turned off.
- Add a ```` file to each paster template. See
Bug Fixes
- ``testing.setUp`` now adds a ``settings`` attribute to the registry (both
when it's passed a registry without any settings and when it creates one).
- The ``testing.setUp`` function now takes a ``settings`` argument, which
should be a dictionary. Its values will subsequently be available on the
returned ``config`` object as ``config.registry.settings``.
- Added "What's New in Pyramid 1.0" chapter to HTML rendering of
- Merged caseman-master narrative editing branch, many wording fixes and
- Fix deprecated example showing ``chameleon_zpt`` API call in testing
narrative chapter.
- Added "Adding Methods to the Configurator via ``add_directive``" section to
Advanced Configuration narrative chapter.
- Add docs for ``add_finished_callback``, ``add_response_callback``,
``route_path``, ``route_url``, and ``static_url`` methods to
``pyramid.request.Request`` API docs.
- Add (minimal) documentation about using I18N within Mako templates to
"Internationalization and Localization" narrative chapter.
- Move content of "Forms" chapter back to "Views" chapter; I can't think of a
better place to put it.
- Slightly improved interface docs for ``IAuthorizationPolicy``.
- Minimally explain usage of custom regular expressions in URL dispatch
replacement markers within URL Dispatch chapter.
- Using the ``pyramid.view.bfg_view`` alias for ``pyramid.view.view_config``
(a backwards compatibility shim) now issues a deprecation warning.
Backwards Incompatibilities
- Using ``testing.setUp`` now registers an ISettings utility as a side
effect. Some test code which queries for this utility after
``testing.setUp`` via queryAdapter will expect a return value of ``None``.
This code will need to be changed.
- When a ``pyramid.exceptions.Forbidden`` error is raised, its status code
now ``403 Forbidden``. It was previously ``401 Unauthorized``, for
backwards compatibility purposes with ``repoze.bfg``. This change will
cause problems for users of Pyramid with ``repoze.who``, which intercepts
``401 Unauthorized`` by default, but allows ``403 Forbidden`` to pass
through. Those deployments will need to configure ``repoze.who`` to also
react to ``403 Forbidden``.
- The default value for the ``cookie_on_exception`` parameter to
``pyramid.session.UnencyrptedCookieSessionFactory`` is now ``True``. This
means that when view code causes an exception to be raised, and the session
has been mutated, a cookie will be sent back in the response. Previously
its default value was ``False``.
Paster Templates
- The ``pyramid_zodb``, ``pyramid_routesalchemy`` and ``pyramid_alchemy``
paster templates now use a default "commit veto" hook when configuring the
``repoze.tm2`` transaction manager in ``development.ini``. This prevents a
transaction from being committed when the response status code is within
the 400 or 500 ranges. See also
1.0a10 (2011-01-18)
Bug Fixes
- URL dispatch now properly handles a ``.*`` or ``*`` appearing in a regex
match when used inside brackets. Resolves issue #90.
Backwards Incompatibilities
- The ``add_handler`` method of a Configurator has been removed from the
Pyramid core. Handlers are now a feature of the ``pyramid_handlers``
package, which can be downloaded from PyPI. Documentation for the package
should be available via, which describes how
to add a configuration statement to your ``main`` block to reobtain this
method. You will also need to add an ``install_requires`` dependency upon
``pyramid_handlers`` to your ```` file.
- The ``load_zcml`` method of a Configurator has been removed from the
Pyramid core. Loading ZCML is now a feature of the ``pyramid_zcml``
package, which can be downloaded from PyPI. Documentation for the package
should be available via, which describes how
to add a configuration statement to your ``main`` block to reobtain this
method. You will also need to add an ``install_requires`` dependency upon
``pyramid_zcml`` to your ```` file.
- The ``pyramid.includes`` subpackage has been removed. ZCML files which use
include the package ``pyramid.includes`` (e.g. ``<include
package="pyramid.includes"/>``) now must include the ``pyramid_zcml``
package instead (e.g. ``<include package="pyramid_zcml"/>``).
- The ``pyramid.view.action`` decorator has been removed from the Pyramid
core. Handlers are now a feature of the ``pyramid_handlers`` package. It
should now be imported from ``pyramid_handlers`` e.g. ``from
pyramid_handlers import action``.
- The ``handler`` ZCML directive has been removed. It is now a feature of
the ``pyramid_handlers`` package.
- The ``pylons_minimal``, ``pylons_basic`` and ``pylons_sqla`` paster
templates were removed. Use ``pyramid_sqla`` (available from PyPI) as a
generic replacement for Pylons-esque development.
- The ``make_app`` function has been removed from the ``pyramid.router``
module. It continues life within the ``pyramid_zcml`` package. This
leaves the ``pyramid.router`` module without any API functions.
- The ``configure_zcml`` setting within the deployment settings (within
``**settings`` passed to a Pyramid ``main`` function) has ceased to have any
- ``pyramid.testing.setUp`` and ``pyramid.testing.tearDown`` have been
undeprecated. They are now the canonical setup and teardown APIs for test
configuration, replacing "direct" creation of a Configurator. This is a
change designed to provide a facade that will protect against any future
Configurator deprecations.
- Add ``charset`` attribute to ``pyramid.testing.DummyRequest``
(unconditionally ``UTF-8``).
- Add ``add_directive`` method to configurator, which allows framework
extenders to add methods to the configurator (ala ZCML directives).
- When ``Configurator.include`` is passed a *module* as an argument, it
defaults to attempting to find and use a callable named ``includeme``
within that module. This makes it possible to use
``config.include('some.module')`` rather than
``config.include('some.module.somefunc')`` as long as the include function
within ``some.module`` is named ``includeme``.
- The ``bfg2pyramid`` script now converts ZCML include tags that have
``repoze.bfg.includes`` as a package attribute to the value
``pyramid_zcml``. For example, ``<include package="repoze.bfg.includes">``
will be converted to ``<include package="pyramid_zcml">``.
Paster Templates
- All paster templates now use ``pyramid.testing.setUp`` and
``pyramid.testing.tearDown`` rather than creating a Configurator "by hand"
within their ```` module, as per decision in features above.
- The ``starter_zcml`` paster template has been moved to the ``pyramid_zcml``
- The wiki and wiki2 tutorials now use ``pyramid.testing.setUp`` and
``pyramid.testing.tearDown`` rather than creating a Configurator "by hand",
as per decision in features above.
- The "Testing" narrative chapter now explains ``pyramid.testing.setUp`` and
``pyramid.testing.tearDown`` instead of Configurator creation and
``Configurator.begin()`` and ``Configurator.end()``.
- Document the ``request.override_renderer`` attribute within the narrative
"Renderers" chapter in a section named "Overriding A Renderer at Runtime".
- The "Declarative Configuration" narrative chapter has been removed (it was
moved to the ``pyramid_zcml`` package).
- Most references to ZCML in narrative chapters have been removed or
redirected to ``pyramid_zcml`` locations.
- Deprecation warnings related to import of the following API functions were
added: ``pyramid.traversal.find_model``, ``pyramid.traversal.model_path``,
``pyramid.traversal.model_path_tuple``, ``pyramid.url.model_url``. The
instructions emitted by the deprecation warnings instruct the developer to
change these method spellings to their ``resource`` equivalents. This is a
consequence of the mass concept rename of "model" to "resource" performed
in 1.0a7.
1.0a9 (2011-01-08)
Bug Fixes
- The ``proutes`` command tried too hard to resolve the view for printing,
resulting in exceptions when an exceptional root factory was encountered.
Instead of trying to resolve the view, if it cannot, it will now just print
- The `self` argument was included in new methods of the ``ISession`` interface
signature, causing ``pyramid_beaker`` tests to fail.
- Readd ``pyramid.traversal.model_path_tuple`` as an alias for
``pyramid.traversal.resource_path_tuple`` for backwards compatibility.
- Add a new API ``pyramid.url.current_route_url``, which computes a URL based
on the "current" route (if any) and its matchdict values.
- ``config.add_view`` now accepts a ``decorator`` keyword argument, a callable
which will decorate the view callable before it is added to the registry.
- If a handler class provides an ``__action_decorator__`` attribute (usually
a classmethod or staticmethod), use that as the decorator for each view
registration for that handler.
- The ``pyramid.interfaces.IAuthenticationPolicy`` interface now specifies an
``unauthenticated_userid`` method. This method supports an important
optimization required by people who are using persistent storages which do
not support object caching and whom want to create a "user object" as a
request attribute.
- A new API has been added to the ```` module named
``unauthenticated_userid``. This API function calls the
``unauthenticated_userid`` method of the effective security policy.
- An ``unauthenticated_userid`` method has been added to the dummy
authentication policy returned by
``pyramid.config.Configurator.testing_securitypolicy``. It returns the
same thing as that the dummy authentication policy's
``authenticated_userid`` method.
- The class ``pyramid.authentication.AuthTktCookieHelper`` is now an API.
This class can be used by third-party authentication policy developers to
help in the mechanics of authentication cookie-setting.
- New constructor argument to Configurator: ``default_view_mapper``. Useful
to create systems that have alternate view calling conventions. A view
mapper allows objects that are meant to be used as view callables to have
an arbitrary argument list and an arbitrary result. The object passed as
``default_view_mapper`` should implement the
``pyramid.interfaces.IViewMapperFactory`` interface.
- add a ``set_view_mapper`` API to Configurator. Has
the same result as passing ``default_view_mapper`` to the Configurator
- ``config.add_view`` now accepts a ``mapper`` keyword argument, which should
either be ``None``, a string representing a Python dotted name, or an
object which is an ``IViewMapperFactory``. This feature is not useful for
"civilians", only for extension writers.
- Allow static renderer provided during view registration to be overridden at
request time via a request attribute named ``override_renderer``, which
should be the name of a previously registered renderer. Useful to provide
"omnipresent" RPC using existing rendered views.
- Instances of ``pyramid.testing.DummyRequest`` now have a ``session``
object, which is mostly a dictionary, but also implements the other session
API methods for flash and CSRF.
Backwards Incompatibilities
- Since the ``pyramid.interfaces.IAuthenticationPolicy`` interface now
specifies that a policy implementation must implement an
``unauthenticated_userid`` method, all third-party custom authentication
policies now must implement this method. It, however, will only be called
when the global function named ````
is invoked, so if you're not invoking that, you will not notice any issues.
- ``pyramid.interfaces.ISession.get_csrf_token`` now mandates that an
implementation should return a *new* token if one doesn't already exist in
the session (previously it would return None). The internal sessioning
implementation has been changed.
- The (weak) "Converting a CMF Application to Pyramid" tutorial has been
removed from the tutorials section. It was moved to the
``pyramid_tutorials`` Github repository.
- The "Resource Location and View Lookup" chapter has been replaced with a
variant of Rob Miller's "Much Ado About Traversal" (originally published at
- Many minor wording tweaks and refactorings (merged Casey Duncan's docs
fork, in which he is working on general editing).
- Added (weak) description of new view mapper feature to Hooks narrative
- Split views chapter into 2: View Callables and View Configuration.
- Reorder Renderers and Templates chapters after View Callables but before
View Configuration.
- Merge Session Objects, Cross-Site Request Forgery, and Flash Messaging
chapter into a single Sessions chapter.
- The Wiki and Wiki2 tutorials now have much nicer CSS and graphics.
- The "view derivation" code is now factored into a set of classes rather
than a large number of standalone functions (a side effect of the
view mapper refactoring).
- The ``pyramid.renderer.RendererHelper`` class has grown a ``render_view``
method, which is used by the default view mapper (a side effect of the
view mapper refactoring).
- The object passed as ``renderer`` to the "view deriver" is now an instance
of ``pyramid.renderers.RendererHelper`` rather than a dictionary (a side
effect of view mapper refactoring).
- The class used as the "page template" in ``pyramid.chameleon_text`` was
removed, in preference to using a Chameleon-inbuilt version.
- A view callable wrapper registered in the registry now contains an
``__original_view__`` attribute which references the original view callable
(or class).
- The (non-API) method of all internal authentication policy implementations
previously named ``_get_userid`` is now named ``unauthenticated_userid``,
promoted to an API method. If you were overriding this method, you'll now
need to override it as ``unauthenticated_userid`` instead.
- Remove (non-API) function of named _map_view.
1.0a8 (2010-12-27)
Bug Fixes
- The name ``registry`` was not available in the ``paster pshell``
environment under IPython.
- If a resource implements a ``__resource_url__`` method, it will be called
as the result of invoking the ``pyramid.url.resource_url`` function to
generate a URL, overriding the default logic. See the new "Generating The
URL Of A Resource" section within the Resources narrative chapter.
- Added flash messaging, as described in the "Flash Messaging" narrative
documentation chapter.
- Added CSRF token generation, as described in the narrative chapter entitled
"Preventing Cross-Site Request Forgery Attacks".
- Prevent misunderstanding of how the ``view`` and ``view_permission``
arguments to add_route work by raising an exception during configuration if
view-related arguments exist but no ``view`` argument is passed.
- Add ``paster proute`` command which displays a summary of the routing
table. See the narrative documentation section within the "URL Dispatch"
chapter entitled "Displaying All Application Routes".
Paster Templates
- The ``pyramid_zodb`` Paster template no longer employs ZCML. Instead, it
is based on scanning.
- Added "Generating The URL Of A Resource" section to the Resources narrative
chapter (includes information about overriding URL generation using
- Added "Generating the Path To a Resource" section to the Resources
narrative chapter.
- Added "Finding a Resource by Path" section to the Resources narrative
- Added "Obtaining the Lineage of a Resource" to the Resources narrative
- Added "Determining if a Resource is In The Lineage of Another Resource" to
Resources narrative chapter.
- Added "Finding the Root Resource" to Resources narrative chapter.
- Added "Finding a Resource With a Class or Interface in Lineage" to
Resources narrative chapter.
- Added a "Flash Messaging" narrative documentation chapter.
- Added a narrative chapter entitled "Preventing Cross-Site Request Forgery
- Changed the "ZODB + Traversal Wiki Tutorial" based on changes to
``pyramid_zodb`` Paster template.
- Added "Advanced Configuration" narrative chapter which documents how to
deal with configuration conflicts, two-phase configuration, ``include`` and
- Fix API documentation rendering for ``pyramid.view.static``
- Add "Pyramid Provides More Than One Way to Do It" to Design Defense
- Changed "Static Assets" narrative chapter: clarify that ``name`` represents
a prefix unless it's a URL, added an example of a root-relative static view
fallback for URL dispatch, added an example of creating a simple view that
returns the body of a file.
- Move ZCML usage in Hooks chapter to Declarative Configuration chapter.
- Merge "Static Assets" chapter into the "Assets" chapter.
- Added narrative documentation section within the "URL Dispatch" chapter
entitled "Displaying All Application Routes" (for ``paster proutes``
1.0a7 (2010-12-20)
Terminology Changes
- The Pyramid concept previously known as "model" is now known as "resource".
As a result:
- The following API changes have been made::
pyramid.url.model_url ->
pyramid.traversal.find_model ->
pyramid.traversal.model_path ->
pyramid.traversal.model_path_tuple ->
pyramid.traversal.ModelGraphTraverser ->
pyramid.config.Configurator.testing_models ->
pyramid.testing.registerModels ->
pyramid.testing.DummyModel ->
- All documentation which previously referred to "model" now refers to
- The ``starter`` and ``starter_zcml`` paster templates now have a
```` module instead of a ```` module.
- Positional argument names of various APIs have been changed from
``model`` to ``resource``.
Backwards compatibility shims have been left in place in all cases. They
will continue to work "forever".
- The Pyramid concept previously known as "resource" is now known as "asset".
As a result:
- The (non-API) module previously known as ``pyramid.resource`` is now
known as ``pyramid.asset``.
- All docs that previously referred to "resource specification" now refer
to "asset specification".
- The following API changes were made::
pyramid.config.Configurator.absolute_resource_spec ->
pyramid.config.Configurator.override_resource ->
- The ZCML directive previously known as ``resource`` is now known as
- The setting previously known as ``BFG_RELOAD_RESOURCES`` (envvar) or
``reload_resources`` (config file) is now known, respectively, as
``PYRAMID_RELOAD_ASSETS`` and ``reload_assets``.
Backwards compatibility shims have been left in place in all cases. They
will continue to work "forever".
Bug Fixes
- Make it possible to succesfully run all tests via ``nosetests`` command
directly (rather than indirectly via ``python nosetests``).
- When a configuration conflict is encountered during scanning, the conflict
exception now shows the decorator information that caused the conflict.
- Added ``debug_routematch`` configuration setting that logs matched routes
(including the matchdict and predicates).
- The name ``registry`` is now available in a ``pshell`` environment by
default. It is the application registry object.
- All environment variables which used to be prefixed with ``BFG_`` are now
prefixed with ``PYRAMID_`` (e.g. ``BFG_DEBUG_NOTFOUND`` is now
- Added "Debugging Route Matching" section to the urldispatch narrative
documentation chapter.
- Added reference to ``PYRAMID_DEBUG_ROUTEMATCH`` envvar and ``debug_routematch``
config file setting to the Environment narrative docs chapter.
- Changed "Project" chapter slightly to expand on use of ``paster pshell``.
- Direct Jython users to Mako rather than Jinja2 in "Install" narrative
- Many changes to support terminological renaming of "model" to "resource"
and "resource" to "asset".
- Added an example of ``WebTest`` functional testing to the testing narrative
- Rearranged chapter ordering by popular demand (URL dispatch first, then
traversal). Put hybrid chapter after views chapter.
- Split off "Renderers" as its own chapter from "Views" chapter in narrative
Paster Templates
- Added ``debug_routematch = false`` to all paster templates.
- Depend on Venusian >= 0.5 (for scanning conflict exception decoration).
1.0a6 (2010-12-15)
Bug Fixes
- 1.0a5 introduced a bug when ``pyramid.config.Configurator.scan`` was used
without a ``package`` argument (e.g. ``config.scan()`` as opposed to
``config.scan('packagename')``. The symptoms were: lots of deprecation
warnings printed to the console about imports of deprecated Pyramid
functions and classes and non-detection of view callables decorated with
``view_config`` decorators. This has been fixed.
- Tests now pass on Windows (no bugs found, but a few tests in the test suite
assumed UNIX path segments in filenames).
- If you followed it to-the-letter, the ZODB+Traversal Wiki tutorial would
instruct you to run a test which would fail because the view callable
generated by the ``pyramid_zodb`` tutorial used a one-arg view callable,
but the test in the sample code used a two-arg call.
- Updated ZODB+Traversal tutorial of all steps to match what's
generated by ``pyramid_zodb``.
- Fix reference to ``repoze.bfg.traversalwrapper`` in "Models" chapter (point
at ``pyramid_traversalwrapper`` instead).
1.0a5 (2010-12-14)
- Add a ``handler`` ZCML directive. This directive does the same thing as
- A new module named ``pyramid.config`` was added. It subsumes the duties of
the older ``pyramid.configuration`` module.
- The new ``pyramid.config.Configurator` class has API methods that the older
``pyramid.configuration.Configurator`` class did not: ``with_context`` (a
classmethod), ``include``, ``action``, and ``commit``. These methods exist
for imperative application extensibility purposes.
- The ``pyramid.testing.setUp`` function now accepts an ``autocommit``
keyword argument, which defaults to ``True``. If it is passed ``False``,
the Config object returned by ``setUp`` will be a non-autocommiting Config
- Add logging configuration to all paster templates.
- ``pyramid_alchemy``, ``pyramid_routesalchemy``, and ``pylons_sqla`` paster
templates now use idiomatic SQLAlchemy configuration in their respective
``.ini`` files and Python code.
- ``pyramid.testing.DummyRequest`` now has a class variable,
``query_string``, which defaults to the empty string.
- Add support for json on GAE by catching NotImplementedError and importing
simplejson from django.utils.
- The Mako renderer now accepts a resource specification for
- New boolean Mako settings variable ``mako.strict_undefined``. See `Mako
Context Variables
<>`_ for
its meaning.
- Depend on Mako 0.3.6+ (we now require the ``strict_undefined`` feature).
Bug Fixes
- When creating a Configurator from within a ``paster pshell`` session, you
were required to pass a ``package`` argument although ``package`` is not
actually required. If you didn't pass ``package``, you would receive an
error something like ``KeyError: '__name__'`` emanating from the
``pyramid.path.caller_module`` function. This has now been fixed.
- The ``pyramid_routesalchemy`` paster template's unit tests failed
(``AssertionError: 'SomeProject' != 'someproject'``). This is fixed.
- Make default renderer work (renderer factory registered with no name, which
is active for every view unless the view names a specific renderer).
- The Mako renderer did not properly turn the ``mako.imports``,
``mako.default_filters``, and ``mako.imports`` settings into lists.
- The Mako renderer did not properly convert the ``mako.error_handler``
setting from a dotted name to a callable.
- Merged many wording, readability, and correctness changes to narrative
documentation chapters from (up to and
including "Models" narrative chapter).
- "Sample Applications" section of docs changed to note existence of Cluegun,
Shootout and Virginia sample applications, ported from their repoze.bfg
origin packages.
- SQLAlchemy+URLDispatch tutorial updated to integrate changes to
``pyramid_routesalchemy`` template.
- Add ``pyramid.interfaces.ITemplateRenderer`` interface to Interfaces API
chapter (has ``implementation()`` method, required to be used when getting
at Chameleon macros).
- Add a "Modifying Package Structure" section to the project narrative
documentation chapter (explain turning a module into a package).
- Documentation was added for the new ``handler`` ZCML directive in the ZCML
- ``pyramid.configuration.Configurator`` is now deprecated. Use
``pyramid.config.Configurator``, passing its constructor
``autocommit=True`` instead. The ``pyramid.configuration.Configurator``
alias will live for a long time, as every application uses it, but its
import now issues a deprecation warning. The
``pyramid.config.Configurator`` class has the same API as
``pyramid.configuration.Configurator`` class, which it means to replace,
except by default it is a *non-autocommitting* configurator. The
now-deprecated ``pyramid.configuration.Configurator`` will autocommit every
time a configuration method is called.
The ``pyramid.configuration`` module remains, but it is deprecated. Use
``pyramid.config`` instead.
1.0a4 (2010-11-21)
- URL Dispatch now allows for replacement markers to be located anywhere
in the pattern, instead of immediately following a ``/``.
- URL Dispatch now uses the form ``{marker}`` to denote a replace marker in
the route pattern instead of ``:marker``. The old colon-style marker syntax
is still accepted for backwards compatibility. The new format allows a
regular expression for that marker location to be used instead of the
default ``[^/]+``, for example ``{marker:\d+}`` is now valid to require the
marker to be digits.
- Add a ``pyramid.url.route_path`` API, allowing folks to generate relative
URLs. Calling ``route_path`` is the same as calling
``pyramid.url.route_url`` with the argument ``_app_url`` equal to the empty
- Add a ``pyramid.request.Request.route_path`` API. This is a convenience
method of the request which calls ``pyramid.url.route_url``.
- Make test suite pass on Jython (requires PasteScript trunk, presumably to
be 1.7.4).
- Make test suite pass on PyPy (Chameleon doesn't work).
- Surrounding application configuration with ``config.begin()`` and
``config.end()`` is no longer necessary. All paster templates have been
changed to no longer call these functions.
- Fix configurator to not convert ``ImportError`` to ``ConfigurationError``
if the import that failed was unrelated to the import requested via a
dotted name when resolving dotted names (such as view dotted names).
- SQLAlchemy+URLDispatch and ZODB+Traversal tutorials have been updated to
not call ``config.begin()`` or ``config.end()``.
Bug Fixes
- Add deprecation warnings to import of ``pyramid.chameleon_text`` and
``pyramid.chameleon_zpt`` of ``get_renderer``, ``get_template``,
``render_template``, and ``render_template_to_response``.
- Add deprecation warning for import of ``pyramid.zcml.zcml_configure`` and
- The ``pyramid_alchemy`` paster template had a typo, preventing an import
from working.
- Fix apparent failures when calling ``pyramid.traversal.find_model(root,
path)`` or ``pyramid.traversal.traverse(path)`` when ``path`` is
(erroneously) a Unicode object. The user is meant to pass these APIs a
string object, never a Unicode object. In practice, however, users indeed
pass Unicode. Because the string that is passed must be ASCII encodeable,
now, if they pass a Unicode object, its data is eagerly converted to an
ASCII string rather than being passed along to downstream code as a
convenience to the user and to prevent puzzling second-order failures from
cropping up (all failures will occur within ``pyramid.traversal.traverse``
rather than later down the line as the result of calling e.g.
Backwards Incompatibilities
- The ``pyramid.testing.zcml_configure`` API has been removed. It had been
advertised as removed since repoze.bfg 1.2a1, but hadn't actually been.
- The ``pyramid.settings.get_settings`` API is now deprecated. Use
``pyramid.threadlocals.get_current_registry().settings`` instead or use the
``settings`` attribute of the registry available from the request
- Removed ``zodbsessions`` tutorial chapter. It's still useful, but we now
have a SessionFactory abstraction which competes with it, and maintaining
documentation on both ways to do it is a distraction.
- Replace Twill with WebTest in internal integration tests (avoid deprecation
warnings generated by Twill).
1.0a3 (2010-11-16)
- Added Mako TemplateLookup settings for ``mako.error_handler``,
``mako.default_filters``, and ``mako.imports``.
- Normalized all paster templates: each now uses the name ``main`` to
represent the function that returns a WSGI application, each now uses
WebError, each now has roughly the same shape of development.ini style.
- Added class vars ``matchdict`` and ``matched_route`` to
``pyramid.request.Request``. Each is set to ``None``.
- New API method: ``pyramid.settings.asbool``.
- New API methods for ``pyramid.request.Request``: ``model_url``,
``route_url``, and ``static_url``. These are simple passthroughs for their
respective functions in ``pyramid.url``.
- The ``settings`` object which used to be available only when
``request.settings.get_settings`` was called is now available as
``registry.settings`` (e.g. ``request.registry.settings`` in view code).
Bug Fixes
- The pylons_* paster templates erroneously used the ``{squiggly}`` routing
syntax as the pattern supplied to ``add_route``. This style of routing is
not supported. They were replaced with ``:colon`` style route patterns.
- The pylons_* paster template used the same string
(``your_app_secret_string``) for the ``session.secret`` setting in the
generated ``development.ini``. This was a security risk if left unchanged
in a project that used one of the templates to produce production
applications. It now uses a randomly generated string.
- ZODB+traversal wiki (``wiki``) tutorial updated due to changes to
``pyramid_zodb`` paster template.
- SQLAlchemy+urldispach wiki (``wiki2``) tutorial updated due to changes to
``pyramid_routesalchemy`` paster template.
- Documented the ``matchdict`` and ``matched_route`` attributes of the
request object in the Request API documentation.
- Obtaining the ``settings`` object via
``registry.{get|query}Utility(ISettings)`` is now deprecated. Instead,
obtain the ``settings`` object via the ``registry.settings`` attribute. A
backwards compatibility shim was added to the registry object to register
the settings object as an ISettings utility when ``setattr(registry,
'settings', foo)`` is called, but it will be removed in a later release.
- Obtaining the ``settings`` object via ``pyramid.settings.get_settings`` is
now deprecated. Obtain it as the ``settings`` attribute of the registry
now (obtain the registry via ``pyramid.threadlocal.get_registry`` or as
Behavior Differences
- Internal: ZCML directives no longer call get_current_registry() if there's
a ``registry`` attribute on the ZCML context (kill off use of
- Internal: Chameleon template renderers now accept two arguments: ``path``
and ``lookup``. ``Lookup`` will be an instance of a lookup class which
supplies (late-bound) arguments for debug, reload, and translate. Any
third-party renderers which use (the non-API) function
``pyramid.renderers.template_renderer_factory`` will need to adjust their
implementations to obey the new callback argument list. This change was to
kill off inappropriate use of threadlocals.
1.0a2 (2010-11-09)
- All references to events by interface
(e.g. ``pyramid.interfaces.INewRequest``) have been changed to reference
their concrete classes (e.g. ````) in
documentation about making subscriptions.
- All references to Pyramid-the-application were changed from mod-`pyramid`
to app-`Pyramid`. A custom role setting was added to ``docs/`` to
allow for this. (internal)
1.0a1 (2010-11-05)
Features (delta from BFG 1.3)
- Mako templating renderer supports resource specification format for
template lookups and within Mako templates. Absolute filenames must
be used in Pyramid to avoid this lookup process.
- Add ``pyramid.httpexceptions`` module, which is a facade for the
``webob.exc`` module.
- Direct built-in support for the Mako templating language.
- A new configurator method exists: ``add_handler``. This method adds
a Pylons-style "view handler" (such a thing used to be called a
"controller" in Pylons 1.0).
- New argument to configurator: ``session_factory``.
- New method on configurator: ``set_session_factory``
- Using ``request.session`` now returns a (dictionary-like) session
object if a session factory has been configured.
- The request now has a new attribute: ``tmpl_context`` for benefit of
Pylons users.
- The decorator previously known as ``pyramid.view.bfg_view`` is now
known most formally as ``pyramid.view.view_config`` in docs and
paster templates. An import of ``pyramid.view.bfg_view``, however,
will continue to work "forever".
- New API methods in ``pyramid.session``: ``signed_serialize`` and
- New interface: ``pyramid.interfaces.IRendererInfo``. An object of this type
is passed to renderer factory constructors (see "Backwards
- New event type: ``pyramid.interfaces.IBeforeRender``. An object of this type
is sent as an event before a renderer is invoked (but after the
application-level renderer globals factory added via
``pyramid.configurator.configuration.set_renderer_globals_factory``, if any,
has injected its own keys). Applications may now subscribe to the
``IBeforeRender`` event type in order to introspect the and modify the set of
renderer globals before they are passed to a renderer. The event object
iself has a dictionary-like interface that can be used for this purpose. For
from import subscriber
from pyramid.interfaces import IRendererGlobalsEvent
def add_global(event):
event['mykey'] = 'foo'
If a subscriber attempts to add a key that already exist in the renderer
globals dictionary, a ``KeyError`` is raised. This limitation is due to the
fact that subscribers cannot be ordered relative to each other. The set of
keys added to the renderer globals dictionary by all subscribers and
app-level globals factories must be unique.
- New class: ``pyramid.response.Response``. This is a pure facade for
``webob.Response`` (old code need not change to use this facade, it's
existence is mostly for vanity and documentation-generation purposes).
- All preexisting paster templates (except ``zodb``) now use "imperative"
configuration (``starter``, ``routesalchemy``, ``alchemy``).
- A new paster template named ``pyramid_starter_zcml`` exists, which uses
declarative configuration.
Documentation (delta from BFG 1.3)
- Added a ``pyramid.httpexceptions`` API documentation chapter.
- Added a ``pyramid.session`` API documentation chapter.
- Added a ``Session Objects`` narrative documentation chapter.
- Added an API chapter for the ``pyramid.personality`` module.
- Added an API chapter for the ``pyramid.response`` module.
- All documentation which previously referred to ``webob.Response`` now uses
``pyramid.response.Response`` instead.
- The documentation has been overhauled to use imperative configuration,
moving declarative configuration (ZCML) explanations to a separate
narrative chapter ``declarative.rst``.
- The ZODB Wiki tutorial was updated to take into account changes to the
``pyramid_zodb`` paster template.
- The SQL Wiki tutorial was updated to take into account changes to the
``pyramid_routesalchemy`` paster template.
Backwards Incompatibilities (with BFG 1.3)
- There is no longer an ``IDebugLogger`` registered as a named utility
with the name ``repoze.bfg.debug``.
- The logger which used to have the name of ``repoze.bfg.debug`` now
has the name ``pyramid.debug``.
- The deprecated API ``pyramid.testing.registerViewPermission``
has been removed.
- The deprecated API named ``pyramid.testing.registerRoutesMapper``
has been removed.
- The deprecated API named ``pyramid.request.get_request`` was removed.
- The deprecated API named ```` was
- The deprecated API named ``pyramid.view.view_execution_permitted``
was removed.
- The deprecated API named ``pyramid.view.NotFound`` was removed.
- The ``bfgshell`` paster command is now named ``pshell``.
- The Venusian "category" for all built-in Venusian decorators
(e.g. ``subscriber`` and ``view_config``/``bfg_view``) is now
``pyramid`` instead of ``bfg``.
- ``pyramid.renderers.rendered_response`` function removed; use
``render_pyramid.renderers.render_to_response`` instead.
- Renderer factories now accept a *renderer info object* rather than an
absolute resource specification or an absolute path. The object has the
following attributes: ``name`` (the ``renderer=`` value), ``package`` (the
'current package' when the renderer configuration statement was found),
``type``: the renderer type, ``registry``: the current registry, and
``settings``: the deployment settings dictionary.
Third-party ``repoze.bfg`` renderer implementations that must be ported to
Pyramid will need to account for this.
This change was made primarily to support more flexible Mako template
- The presence of the key ``repoze.bfg.message`` in the WSGI environment when
an exception occurs is now deprecated. Instead, code which relies on this
environ value should use the ``exception`` attribute of the request
(e.g. ``request.exception[0]``) to retrieve the message.
- The values ``bfg_localizer`` and ``bfg_locale_name`` kept on the request
during internationalization for caching purposes were never APIs. These
however have changed to ``localizer`` and ``locale_name``, respectively.
- The default ``cookie_name`` value of the ``authtktauthenticationpolicy`` ZCML
now defaults to ``auth_tkt`` (it used to default to ``repoze.bfg.auth_tkt``).
- The default ``cookie_name`` value of the
``pyramid.authentication.AuthTktAuthenticationPolicy`` constructor now
defaults to ``auth_tkt`` (it used to default to ``repoze.bfg.auth_tkt``).
- The ``request_type`` argument to the ``view`` ZCML directive, the
``pyramid.configuration.Configurator.add_view`` method, or the
``pyramid.view.view_config`` decorator (nee ``bfg_view``) is no longer
permitted to be one of the strings ``GET``, ``HEAD``, ``PUT``, ``POST`` or
``DELETE``, and now must always be an interface. Accepting the
method-strings as ``request_type`` was a backwards compatibility strategy
servicing repoze.bfg 1.0 applications. Use the ``request_method``
parameter instead to specify that a view a string request-method predicate.
