Revision comparisons
|
|
~~~~~~~~~~~~~~~~~~~~

|
|
|
|
Wagtail now provides the ability to view differences between revisions of a page, from the revisions listing page and when reviewing a page in moderation. This feature was developed by Karl Hobley, Janneke Janssen and Matt Westcott. Thank you to Blackstone Chambers for sponsoring this feature.

|
Many-to-many relations on page models
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|

|
|
|
|
Wagtail now supports a new field type ``ParentalManyToManyField`` that can be used to set up many-to-many relations on pages. For details, see the :ref:`tutorial_categories` section of the tutorial. This feature was developed by Thejaswi Puthraya and Matt Westcott.
|
|
|
|
|
|
Bulk-deletion of form submissions
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Form builder form submissions can now be deleted in bulk from the form submissions index page. This feature was sponsored by St John's College, Oxford and developed by Karl Hobley.
|

|
|
|
Accessing parent context from StreamField block ``get_context`` methods
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The ``get_context`` method on StreamField blocks now receives a ``parent_context`` keyword argument, consisting of the dict of variables passed in from the calling template. For example, this makes it possible to perform pagination logic within ``get_context``, retrieving the current page number from ``parent_context['request'].GET``. See :ref:`get_context on StreamField blocks <streamfield_get_context>`. This feature was developed by Mikael Svensson and Peter Baumgartner.

|
Welcome message customisation for multi-tenanted installations
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The welcome message on the admin dashboard has been updated to be more suitable for multi-tenanted installations. Users whose page permissions lie within a single site will now see that site name in the welcome message, rather than the installation-wide ``WAGTAIL_SITE_NAME``. As before, this message can be customised, and additional template variables have been provided for this purpose - see :ref:`custom_branding`. This feature was developed by Jeffrey Chau.

|
|
* Added ``get_api_representation`` method to streamfield blocks allowing the JSON representation in the API to be customised (Marco Fucci)

Upgrade considerations
|
|
======================
|
|
|
|
``django-modelcluster`` and ``django-taggit`` dependencies updated
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Wagtail now requires version 3.0 or later of ``django-modelcluster`` and version 0.20 or later of ``django-taggit``; earlier versions are unsupported. In normal circumstances these packages will be upgraded automatically when upgrading Wagtail; however, if your Wagtail project has a requirements file that explicitly specifies an older version, this will need to be updated.
|
|
|
|
|
|
``get_context`` methods on StreamField blocks need updating
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Previously, ``get_context`` methods on StreamField blocks returned a dict of variables which would be merged into the calling template's context before rendering the block template. ``get_context`` methods now receive a ``parent_context`` dict, and are responsible for returning the final context dictionary with any new variables merged into it. The old calling convention is now deprecated, and will be phased out in Wagtail 1.11.
|
|
|
|
In most cases, the method will be calling ``get_context`` on the superclass, and can be updated by passing the new ``parent_context`` keyword argument to it:
|
|
|
|
.. code-block:: python
|
|
|
|
class MyBlock(Block):
|
|
|
|
def get_context(self, value):
|
|
context = super(MyBlock, self).get_context(value)
|
|
...
|
|
return context
|
|
|
|
becomes:
|
|
|
|
.. code-block:: python
|
|
|
|
class MyBlock(Block):
|
|
|
|
def get_context(self, value, parent_context=None):
|
|
context = super(MyBlock, self).get_context(value, parent_context=parent_context)
|
|
...
|
|
return context
|
|
|
|
|
|
Note that ``get_context`` methods on page models are unaffected by this change.
