Customizing django-messages
===========================
There are multiple levels at which you can customize django-messages without
altering the code directly.
Templates
---------
Django-messages comes with a set of built-in templates which you can use.
If these templates don't fit your project you can override any or all of them
by putting files with the same filenames in one the directories listes in
``TEMPLATES_DIRS`` in your ``settings.py``.
Django-messages uses the following templates:
* :file:`django_messages/base.html` - A base template from which all the
following templates inherit. Maybe it's enough to customize this template
for your project.
* :file:`django_messages/compose.html` - This template is rendered, when a
user composes a new messages.
* :file:`django_messages/inbox.html` - This template lists the users inbox.
* :file:`django_messages/new_messages.html` - This template is used to
construct the notification mail sent to a user, whenever a new message is
received.
* :file:`django_messages/outbox.html` - This template lists the users outbox
aka sent messages.
* :file:`django_messages/trash.html` - This template lists the users trash.
* :file:`django_messages/view.html` - This template renders a single message
with all details.
Additionally django-message provides a set of template for django-notification.
These template can be found in :file:`django_messages/templates/notification/`
and can also be overwritten in one of your project's ``TEMPLATE_DIRS``.
URL-conf
--------
If you want to further customize how django-messages works it is possible to
write your own url-conf instead of including ``django_messages.urls`` in your
root url-conf. This not only allows changing the url structure but also allows
modifying the kwargs passed to the views and therefore modifying some behaviour.
Please note: If you provide your own url-conf, or urlpatterns directly embedded
in your root url-conf, you shouldn't include ``django_messages.urls``.
Three common customizations are described in more detail below.
Modifying template names
~~~~~~~~~~~~~~~~~~~~~~~~
If overwriting templates in your project's ``TEMPLATE_DIRS`` does not provide
enough freedom, you can change the names of the used templates by providing
a `template_name` keyword argument to the views. Every view which renders a
template accepts this keyword-argument.
If you want to change the template the ``inbox`` view uses to ``my_inbox.html``
instead of the default ``django_messages/inbox.html`` you can use this line
in your own url-conf::
url(r'^inbox/$',
inbox,
{'template_name': 'my_inbox.html',},
name='messages_inbox'),
Modifying form classes
~~~~~~~~~~~~~~~~~~~~~~
If you want to use your own form for composing messages, for example to add
new features, you can simply pass the form-class to the views via kwargs.
Every view which renders a form accepts a `form_class` keyword argument to
specify the form-class.
If you want to use Your own ``MyComposeForm`` you can pass it to the view by
using a line like the following in your own url-conf::
from somewhere import MyComposeForm
...
url(r'^compose/$',
compose,
{'form_class': MyComposeForm,},
name='messages_compose'),
Modifying success urls
~~~~~~~~~~~~~~~~~~~~~~
All views, which will redirect the user after a successfull action accept a
`success_url` keyword argument to specify the destination url. The ``delete``
and ``undelete`` views will additionally check if a ``next`` parameter is
provided in the querystring appended to the url.
If you don't want to append the next target to the url, or want to change
the redirecting behaviour of other views, you can pass a ``success_url``
parameter in your own url-conf, for example like this::
url(r'^delete/(?P<message_id>[\d]+)/$',
delete,
{'success_url': '/profile/',},
name='messages_delete'),
