0.9.9 (2013-09-23)
Bug Fixes
- rename country specific locales to only include language
- Un-break single select widget. See
0.9.8 (2013-09-01)
- ``deform.widget.RichTextWidget`` now accepts a dict/two-tuple ``options``
for specifying arbitrary options to pass to TinyMCE's ``init`` function.
All default options are now part of the class itself (where possible)
and can be customised by using ``options``.
- Widgets now accept an ``item_css_class`` argument. This argument, when
provided, sets a class value on the top level element of the item template
which surrounds the widget (usually an <li>).
- DateTime widget now handles stripping timezones from ISO-formatted strings
that include microseconds. Previously it would just choke.
Bug Fixes
- Trigger a change event when adding/removing sequence items.
- Add optional label to checkbox widget.
- Raise a ValueError exception when the prototype
for a field in a sequence has no name. See
- Worked on the templates to make as many widgets be proper HTML. Deformdemo
now includes a validator which can be used for checking. The major changes
involve ensuring that only `<li>` can be children of `<ul>` and that labels
always refer to distinct fields. Also labels are set around fields to provide
better touch targets: you can click on the label as well as the field.
Validation still raises some errors about invalid attributes such as
`prototype` but these can be safely ignored: browsers will ignore things they
don't know about - this is defined in HTML 5 (it used to be guess work).
Having the right `<label>` added a wart to mappings where the first item
doesn't get a counter because the label is already assigned. This may be
revisited as it seems to affect only mappings.
See for further context.
0.9.7 (2013-03-06)
Bug Fixes
- Readonly checkbox template had a logic error.
- Corrected the expected server response when using the Autocomplete widget.
0.9.6 (2013-01-10)
Bug Fixes
- Fixed remove bug in nested sequences. See
- Fixed bug wherein items added to a sequence nor the initial items rendered
in a sequence would not reflect the correct defaults of the item widget.
- Fix bug where native datetime/date widget rendering competed with jQuery
datetime/date widget rendering. See
- Depend on and use zope.deprecation to deprecate Set class.
- Deform now depends on Colander >= 1.0a1 (previously it depended on >= 0.8).
It requires Colander 1.0a1's newer ``cstruct_children`` and
``appstruct_children`` methods of schema objects as well as being able to
import objects from Colander that don't exist in earlier versions.
- Deform now depends on Chameleon >= 2.5.1 (previously it depended on
>= 1.2.3). It requires the Markup class supplied by this version or better.
- Deform no longer has a setup_requires dependency on setuptools_git
(useless, as the version on PyPI is broken).
- now includes all testing requirements in tests_require that are in
testing extras and vice versa.
- Allow SelectWidget to produce <optgroup> HTML tags. See
- Allow ``deform.form.Form`` constructor to accept an ``autocomplete``
keyword argument, which controls the ``autocomplete`` attribute of the form
- Add Python 3.3 Trove classifier.
- Pass through unknown keys in a ``filedict`` FileData serialization (FBO of
passing out of band information).
- ``deform.Set`` type deprecated in favor of use of ``colander.Set``.
- Give the preview_url method of the tempstore access to the stored
item. [tomster]
- Add ``style`` attribute/arguments to textinput-related widgets allowing you
to set the style of the tag by hand.
- Allow ``deform.widget.SequenceWidget`` constructor to accept an ``orderable``
keyword argument. Default is ``False``. If ``True``, allow drag-and-drop
reordering of SequenceWidget items (via jQuery UI Sortable).
- The default widget for the colander.Money type is now
- Built-in widgets may have a 'readonly' attribute/constructor-argument, to
indicate that a form field associated with the widget should use its
readonly template instead of its normal readwrite template. A ``readonly``
keyword argument can still be passed to ``Field.serialize`` to render a
field as readonly, like in older versions.
- ``deform.field.Field`` now has a ``__contains__`` method, which returns
``True`` if the named field is a subfield of the field on which it is
- ``deform.field.Field`` now has a ``validate_pstruct`` method which works
like ``validate`` except it accepts a pstruct directly instead of accepting
a list of controls.
- ``deform.field.Field.validate`` now accepts a ``subcontrol`` argument for
validating a submapping of a form.
- In support of "retail" form rendering, the ``serialize`` method of widgets
now accepts arbitrary keyword arguments. These are used as top-level value
overrides to widget templates.
- In support of "retail" form rendering, the ``serialize`` method of a Field
now accepts arbitrary keyword arguments. These are passed along to it's
widget's ``serialize`` method.
- It is now possible to pass an ``appstruct`` argument to the
``deform.Field`` (and by extension, the ``deform.Form``) constructor. When
you do so, you can omit passing an ``appstruct`` argument to the ``render``
method of the field/form. Fields set a cstruct value recursively when
supplied with an ``appstruct`` argument to their constructor. This is in
support of "retail" form rendering.
- Form/field objects are now initialized with a cstruct (recursively) when
created. This means that accessing form.cstruct will return the current
set of rendering values. This value is reset during validation, so after a
validation is done you can re-render the form to show validation errors.
This is in support of "retail" form rendering.
- Form/field objects now have peppercorn-field-outputting methods:
``start_mapping``, ``end_mapping``, ``start_sequence``, ``end_sequence``,
``start_rename``, ``end_rename`` in support of retail form rendering.
- The ``deform.Field`` (and therefore ``deform.Form``) classes now expose a
``render_template`` method, which injects ``field`` and ``cstruct`` into
the dictionary passed to the template if they don't already exist in the
``**kw`` passed. This is in support of retail form rendering.
- Add ``set_appstruct`` and ``set_pstruct`` methods to Field; these accept,
respectively, an appstruct or a pstruct and set the cstruct related to the
field to the deserialized or serialized value.
- Add a (weak) "Retail Form Rendering" chapter to the docs.
0.9.5 (2012-04-27)
- Add translations for TinyMCE. Thanks OCHIAI, Gouji.
- Japanese translation thanks to OCHIAI, Gouji.
- Modified Russian translation thanks to aleksandr.rakov
- Date(Time)Widget supports now options to configure it, thx to gaston
tjebbes, kiorky
- FileUploadWidget now sanitizes IE/Windows whole-path filenames before
passing them back to the caller during deserialization/validation.
- Add docs and dev aliases ala Pyramid.
- Add MoneyInputWidget widget type.
- Allow a custom i18n domain to be used for the "Add ${subitem_title}"
link of a SequenceWidget. See .
- Allow the use of Integer values with SelectWidget. See .
- CheckedInputWidget and CheckedPasswordWidget now populate the "confirm"
element with the cstruct value (for edit forms).
- Update to JQuery 1.7.2.
- Update to jquery.form 3.09.
0.9.4 (2012-02-14)
- No longer Python 2.5 compatible. Python 2.6+ is required.
- Python 3.2 compatible.
- Translate title attribute for remove button in sequence fields.
- Do not output empty error messages for sequence items. After translation
these would insert the PO file metadata.
- Update to lingua for translations, add french translation
- fix multiple i18n issues.
- Fix a bug where displaying error could lead on an error when you have
imbricated Mapping objects
- Fix issue #54: does not show validation errors from the top node of
the schema. See for more
- Previously, all CheckedInputWidget and CheckedPasswordWidget fields had
hardcoded input[name] attributes of 'value' and 'confirm'. When
deserializing a form, this caused colander.null to be passed to the widget
deserialization function since neither submitted value matched the name of
the field. This change simply replaces 'value' with the name of the field
and 'confirm' with the name of the field with '-confirm' appended.
- In select widget, add css_class to <select> rather than only <option>.
- Allow RichText fields to load their editor only after clicking on them
- There is no longer a ``deform_ajaxify`` global javascript function.
Instead forms are AJAXified directly by the javascript callback for the
0.9.3 (2011-08-10)
- Update Dutch translations.
- Translate title and description of items for sequence fields.
- Add a new API method to field objects: ``translate``. This method will use
the translator passed to the underlying renderer to translate message ids
into text.
0.9.2 (2011-07-22)
- Chameleon 2 compatibility.
- Use default widgets for a schema's baseclass if known instead of always
falling back to a text widget.
- Deform now includes a ``beautify.css`` (contributed by Ergo^) in its static
directory, which can be used to make form element styling prettier.
- Moved ``deformdemo`` into its own package and Github repository
0.9.1 (2011-06-23)
- Add Dutch translation.
- Add the ``deform.widget.DateTimeWidget`` widget, which uses the jQueryUI
Timepicker add-on.
``DateTimeWidget`` uses the ISO8601 combined date and time format
internally, as expected by ``colander.DateTime``, but converts to
the more friendly separate date and time format for display in the
This widget is now the default for colander.DateTime schema types.
- Upgrade to jquery-ui 1.8.11, as required by the timepicker.
- Compile all ``.po`` files to ``.mo`` in ``deform/locale`` and remove Texan
locale (funny, but breaks ``python compile_catalog`` with an
UnknownLocale error.)
- Fix references to repoze.bfg and update obsoletes URLs in the demo application
- Remove unused ``jquery.autocomplete.min.js`` file from static directory.
- SelectWidget now has a ``size`` attribute to support single select widgets
that are not dropdowns.
- The value fed to the ``deform.form.Button`` class as ``name`` would
generate an invalid HTML id if it contained spaces. Now it converts spaces
to underscores if they exist in the name. See .
- Deformdemo application now has a Time field demonstration.
- Deform Chameleon templates now contain i18n:translate tags.
- German translation updated.
- Fixed invalid HTML generated for "select" widget.
- When using an ajax form without a redirect, a submit overwrites the form.
In the case of a form validation failure on first submit, no event handlers
were registered to submit the form via ajax on the second submit. This is
now fixed. See .
0.9 (2011-03-01)
- Moved to GitHub (
- Added tox.ini for testing purposes.
- Fix select dropdown behavior on Firefox by fixing CSS (closes
- Removed ``wufoo.css``, minimized ``form.css``. Changed templates around to
deal with CSS changes.
- Sequence widgets now accept a min_len and a max_len argument, which
influences its display of close and add buttons.
- Convert demo application from repoze.bfg to Pyramid.
- Depend on Chameleon<1.999 (deform doesn't yet work with Chameleon 2).
0.8.1 (2010-12-17)
- Allow ``deform.form.Button`` class to be passed a ``disabled`` flag (false
by default). If a Button is disabled, its HTML ``disabled`` setting will
be set true.
0.8 (2010-12-02)
- Added Polish locale data: thanks to Marcin Lulek.
Bug Fixes
- Fix dynamic sequence item adding on Chrome and Firefox 4. Previously if
there was a validation error rendering a set of sequence items, the "add
more" link would be rendered outside the form, which would cause it to not
work. Wrapping the sequence item <li> element in a <ul> fixed this.
0.7 (2010-10-10)
- Added Danish locale.
- Added Spanish locale: thanks to David Cerna for the translations!
- ``DatePartsWidget`` now renders error "Required" if all blank or
"Incomplete" if partially blank for consistency with the other widgets.
- Different styling involving <li> and <ul> for checkbox choice,
checked input, radio choice, checked password, and dateparts widgets
(via Ergo^). See
- Deform now depends on ``colander`` version 0.8 or better (the demo
wants to use schema bindings).
- Deform now depends on ``Chameleon`` (uppercase) rather than
``chameleon`` to allow for non-PyPI servers.
- New addition to the demonstration application: schema binding.
0.6 (2010-09-03)
- Sequence widgets are no longer ``structural`` by default; they now
print the label of the sequence above the sequence adder.
- Radio buttons in a radio button choice widget are now spaced closer
together and the button is on the left hand side.
- The sequence remove button is no longer an image.
- The sequence widget now puts the sequence adding link *after* any
existing items in the sequence (previously the link was always
beneath the sequence title).
- It is now possible to associate a widget with a schema node within
the schema directly. For example::
import colander
import deform.widget
class MySchema(Schema):
description = colander.SchemaNode(
For more information, see "Changing the Default Widget Associated
With a Field" in the documentation.
- The constructor of ``deform.Field`` objects (and thus
``deform.Form`` objects) now accept arbitrary keyword arguments,
each of which is attached to the field or form object being
constructed, as well as being attached to its descendant fields
- The form object's template now respects the ``css_class`` argument /
attribute of the form node.
- CheckboxChoice and RadioChoice widgets now use <ul> and <li> to
display individual choice elements (thanks to Ergo^), and both
widgets put the label after the element instead of before as
- The ``deform.widget.AutocompleteInputWidget`` widget now uses
`JQuery UI's autocomplete sublibrary
<>` instead of the
``jquery.autocomplete`` library to perform its job in order to
reduce the number of libraries needed by Deform. Some options have
been changed as a result, and the set of resources returned by
``form.get_widget_resources`` has changed.
This change also implies that when a widget which uses a remote URL
as a ``values`` input, the remote URL must return a JSON structure
instead of a ``\n``-delimited list of values.
- This Deform version requires ``colander`` version 0.7.3 or better.
Bug Fixes
- ``RichTextWidget``, ``AutocompleteInputWidget``, ``TextInputWidget``
with input masks, and ``CheckedInputWidget`` with input masks could
not be used properly within sequences. Now they can be. See also
``Internal`` and ``Backwards Incompatibilities`` within this
release's notes. This necessitated new required ``deform.load()``
and ``deform.addCallback()`` JavaScript APIs.
- Radio choice widgets included within a submapping no longer put
their selections on separate lines.
- Rich text widgets are now 500 pixels wide by default instead of 640.
- RadioChoiceWidgets did not work when they were used within
sequences. Making them work required some changes to the its
template and it added a dependency on ``peppercorn`` >= 0.3.
- To make radio choice widgets work within sequences, the
deform.addSequenceItem JavaScript method needed to be changed. It
will now change the value of ``name`` attributes which contain a
marker that looks like an field oid (e.g. ``deformField1``), and,
like the code which changes ids in the same manner, appends a random
component (e.g. ``deformField1-HL6sgP``). This is to support radio
button groupings.
- The mapping and sequence item templates now correctly display errors
with ``msg`` values that are lists. Previously, a repr of a Python
list was displayed when a widget had an error with a ``msg`` value
that was a list; now multiple <p> nodes are inserted into the
rendering, each <p> node containing an individual error message.
(Note that this change requires colander 0.7.3).
Backwards Incompatibilities
- The JavaScript function ``deform.load()`` now *must* be called by
the HTML page (usually in a script tag near the end of the page, ala
``<script..>deform.load()</script>``) which renders a Deform form in
order for widgets which use JavaScript to do proper event and
behavior binding. If this function is not called, built-in widgets
which use JavaScript will no longer function properly.
- The JavaScript function ``deformFocusFirstInput`` was removed. This
is now implied by ``deform.load()``.
- The ``closebutton_url`` argument to the SequenceWidget no longer
does anything. Style the widget template via CSS to add an image.
- Provided better instructions for running the demo app and running
the tests for the demo app in ``deformdemo/README.txt``.
- Try to prevent false test failures by injecting sleep statements in
things that use ``browser.key_press``.
- Moved ``deformdemo/tests/`` to ``deformdemo/`` as
well as moving ``deformdemo/tests/`` to
``deformdemo/``. Removed the ``deformdemo/tests``
- The date input widget now uses JQueryUI's ``datepicker``
functionality rather than relying on JQuery Tools' ``date`` input.
The latter was broken for sequences, and the former works fine.
- The various deform* JavaScript functions in ``deform.js`` have now
been moved into a top-level namespace. For example, where it was
necessary to call ``deformFocusFirstInput()`` before, it is now
necessary to call ``deform.focusFirstInput()``.
- Make the TinyMCE rich text widget use ``mode: 'exact'`` instead of
``mode: 'textareas'``.
- ``richtext``, ``autocomplete_input``, ``textinput``,
``checked_input``, and ``dateinput``, and ``form`` templates now use
the new ``deform.addCallback`` indirection instead of each
registering their own JQuery callback or performing their own
initialization logic, so that each may be used properly within
- Change sequence adding logic to be slightly simpler.
- The sample app form page now calls ``deform.load()`` rather than
- Added new demo app views for showing a sequence of autocompletes, a
sequence of dateinputs, a sequence of richtext fields, a sequence of
radio choice widgets and a sequence of text inputs with masks and
tests for same.
- Added a note about ``get_widget_resources`` to the "Basics"
- Added a note about ``deform.load()`` JavaScript requiredness to the
"Basics" chapter.
- Add new top-level sections named ``Widget Templates`` and ``Widget
JavaScript`` to the "Widgets" chapter.
0.5 (2010-08-25)
- Added features which make it possible to inquire about which
resources (JavaScript and CSS resources) are required by all the
widgets that make up a form rendering. Also make it possible for a
newly created widget to specify its requirements. See "Widget
Requirements and Resources" in the widgets chapter of the
- Add the ``get_widget_requirements`` method to ``deform.Field``
- Add the ``get_widget_resources`` method to ``deform.Field``
- Allow ``deform.Field`` (and ``deform.Form``) objects to accept a
"resource registry" as a constructor argument.
- Add the ``deform.Field.set_widgets`` method, which allows a
(potentially nested) set of widgets to be applied to children fields
of the field upon which it is called.
- Add the ``deform.widget.TextInputCSV`` widget. This widget is
exactly like the ``deform.widget.TextAreaCSV`` widget except it
accepts a single line of input only.
- The default widget for ``colander.Tuple`` schema types is now
- The ``deform.widget.FileUploadWidget`` now returns an instance of
``deform.widget.filedict`` instead of a plain dictionary to make it
possible (using isinstance) to tell the difference between file
upload data and a plain data dictionary for highly generalized
persistence code.
0.4 (2010-08-22)
Bug Fixes
- When the hidden widget is used to deserialize a field, return
``colander.null`` rather than the empty string so that it may be
used to represent non-text fields such as ``colander.Integer``.
This is isomorphic to the change done previously to
``deform.TextInputWidget`` to support nontextual empty fields.
- Fix typo about overriding templates using set_zpt_renderer in
templating chapter.
- Fix link to imperative schema within in Colander docs within "Basics".
- Remove duplicate ``deform.widget.DateInputWidget`` class definition.
- Add a ``deform.widget.RichTextWidget`` widget, which adds the
TinyMCE WYSIWIG javascript editor to a text area.
- Add a ``deform.widget.AutocompleteInputWidget`` widget, which adds
a text input that can be supplied a URL or iterable of choices to
ease the search and selection of a finite set of choices.
- The ``deform.widget.Widget`` class now accepts an extra keyword
argument in its constructor: ``css_class``.
- All widgets now inherit a ``css_class`` attribute from the base
``deform.widget.Widget`` class. If `css_class`` contains a value,
the "primary" element in the rendered widget will get a CSS
``class`` attribute equal to the value ("primary" is defined by the
widget template's implementor).
- The ``deform.Field`` class now as an ``__iter__`` method which
iterates over the children fields of the field upon which it is
called (``for item in field`` == ``for item in field.children``).
0.3 (2010-06-09)
Bug Fixes
- Change default form action to the empty string (rather than ``.``).
Thanks to Kiran.
- Add ``deform.widget.DateInputWidget`` widget, which is a date picker
widget. This has now become the default widget for the
``colander.Date`` schema type, preferred to the date parts widget.
- Add text input mask capability to ``deform.widget.TextInputWidget``.
- Add text input mask capability to
Backwards Incompatibilities
- Custom widgets must now check for ``colander.null`` rather than
``None`` as the null sentinel value.
- Dependency on a new (0.7) version of Colander, which has been
changed to make using proper defaults possible; if you've used the
``default`` argument to a ``colander.SchemaNode``, or if you've
defined a custom Colander type, you'll want to read `the updated
Colander documentation <>`_
(particularly the changelist). Short story: use the ``missing``
argument instead.
- If you've created a custom widget, you will need to tweak it
slightly to handle the value ``colander.null`` as input to both
``serialize`` and ``deserialize``. See the Deform docs at
` <>`_ for
more information.
0.2 (2010-05-13)
- Every form has a formid now, defaulting to ``deform``. The formid
is used to compute the id of the form tag as well as the button ids
in the form. Previously, if a formid was not passed to the Form
constructor, no id would be given to the rendered form and the
form's buttons would not be prefixed with any formid.
- The ``deform.Form`` class now accepts two extra keyword arguments in
its constructor: ``use_ajax`` and ``ajax_options``.
If ``use_ajax`` is ``True``, the page is not reloaded when a submit
button is pressed. Instead, the form is posted, and the result
replaces the DOM node on the page.
``ajax_options`` is a string which allows you to pass extra options
to the underlying AJAX form machinery when ``use_ajax`` is True.
- Added a couple Ajax examples to the demo app.
- Add a rudimentary Ajax chapter to the docs.
0.1 (2010-05-09)
- Initial release.
