What's new
|
|
==========
|
|
|
|
Site settings module
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Wagtail now includes a contrib module (previously available as the `wagtailsettings <https://pypi.python.org/pypi/wagtailsettings/>`_ package) to allow administrators to edit site-specific settings.
|
|
|
|
See: :doc:`/reference/contrib/settings`
|
|
|
|
|
|
Jinja2 support
|
|
~~~~~~~~~~~~~~
|
|
|
|
The core templatetags (``pageurl``, ``slugurl``, ``image``, ``richtext`` and ``wagtailuserbar``) are now compatible with Jinja2 so it's now possible to use Jinja2 as the template engine for your Wagtail site.
|
|
|
|
Note that the variable name ``self`` is reserved in Jinja2, and so Wagtail now provides alternative variable names where ``self`` was previously used: ``page`` to refer to page objects, and ``value`` to refer to StreamField blocks. All code examples in this documentation have now been updated to use the new variable names, for compatibility with Jinja2; however, users of the default Django template engine can continue to use ``self``.
|
|
|
|
See: :doc:`/reference/jinja2`
|
|
|
|
|
|
Site-specific redirects
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
You can now create redirects for a particular site using the admin interface.
|
|
|
|
|
|
Search API improvements
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Wagtail's image and document models now provide a ``search`` method on their QuerySets, making it easy to perform searches on filtered data sets. In addition, search methods now accept two new keyword arguments:
|
|
|
|
* ``operator``, to determine whether multiple search terms will be treated as 'or' (any term may match) or 'and' (all terms must match);
|
|
* ``order_by_relevance``, set to True (the default) to order by relevance or False to preserve the QuerySet's original ordering.
|
|
|
|
See: :ref:`wagtailsearch_searching`
|
|
|
|
|
|
``max_num`` and ``min_num`` parameters on inline panels
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Inline panels now accept the optional parameters ``max_num`` and ``min_num``, to specify the maximum / minimum number of child items that must exist in order for the page to be valid.
|
|
|
|
See: :ref:`inline_panels`
|
|
|
|
|
|
``get_context`` on StreamField blocks
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
StreamField blocks now :ref:`provide a get_context method <streamfield_get_context>` that can be overridden to pass additional variables to the block's template.
|
|
|
|
|
|
Browsable API
|
|
~~~~~~~~~~~~~
|
|
|
|
The Wagtail API now incorporates the browsable front-end provided by Django REST Framework. Note that this must be enabled by adding ``'rest_framework'`` to your project's ``INSTALLED_APPS`` setting.
|
|
|
|
|
|
Python 3.5 support
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
Wagtail now supports Python 3.5 when run in conjunction with Django 1.8.6 or later.
|
|
|
|
|
|

Bug fixes
|
|
~~~~~~~~~
|
|
|

Upgrade considerations
|
|
======================
|
|
|
|
``PageManager.sibling_of(page)`` and ``PageManager.not_sibling_of(page)`` have changed behaviour
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
In previous versions of Wagtail, the ``sibling_of`` and ``not_sibling_of`` methods behaved inconsistently depending on whether they were called on a manager (e.g. ``Page.objects.sibling_of(some_page)`` or ``EventPage.objects.sibling_of(some_page)``) or a QuerySet (e.g. ``Page.objects.all().sibling_of(some_page)`` or ``EventPage.objects.live().sibling_of(some_page)``).
|
|
|
|
Previously, the manager methods behaved as *exclusive* by default; that is, they did not count the passed-in page object as a sibling of itself:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> event_1 = EventPage.objects.get(title='Event 1')
|
|
>>> EventPage.objects.sibling_of(event_1)
|
|
[<EventPage: Event 2>] # OLD behaviour: Event 1 is not considered a sibling of itself
|
|
|
|
|
|
This has now been changed to be *inclusive* by default; that is, the page is counted as a sibling of itself:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> event_1 = EventPage.objects.get(title='Event 1')
|
|
>>> EventPage.objects.sibling_of(event_1)
|
|
[<EventPage: Event 1>, <EventPage: Event 2>] # NEW behaviour: Event 1 is considered a sibling of itself
|
|
|
|
|
|
If the call to ``sibling_of`` or ``not_sibling_of`` is chained after another QuerySet method - such as ``all()``, ``filter()`` or ``live()`` - behaviour is unchanged; this behaves as *inclusive*, as it did in previous versions:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> event_1 = EventPage.objects.get(title='Event 1')
|
|
>>> EventPage.objects.all().sibling_of(event_1)
|
|
[<EventPage: Event 1>, <EventPage: Event 2>] # OLD and NEW behaviour
|
|
|
|
|
|
If your project includes queries that rely on the old (exclusive) behaviour, this behaviour can be restored by adding the keyword argument ``inclusive=False``:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> event_1 = EventPage.objects.get(title='Event 1')
|
|
>>> EventPage.objects.sibling_of(event_1, inclusive=False)
|
|
[<EventPage: Event 2>] # passing inclusive=False restores the OLD behaviour
|
|
|
|
|
|
``Image.search`` and ``Document.search`` methods are deprecated
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The ``Image.search`` and ``Document.search`` methods have been deprecated in favour of the new QuerySet-based search mechanism - see :ref:`wagtailsearch_images_documents_custom_models`. Code using the old ``search`` methods should be updated to search on QuerySets instead; for example:
|
|
|
|
.. code-block:: python
|
|
|
|
Image.search("Hello", filters={'uploaded_by_user': user})
|
|
|
|
can be rewritten as:
|
|
|
|
.. code-block:: python
|
|
|
|
Image.objects.filter(uploaded_by_user=user).search("Hello")
|
|
|
|
|
|
Wagtail API requires adding ``rest_framework`` to INSTALLED_APPS
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
If you have the Wagtail API (``wagtail.contrib.wagtailapi``) enabled, you must now add ``'rest_framework'`` to your project's ``INSTALLED_APPS`` setting. In the current version the API will continue to function without this app, but the browsable front-end will not be available; this ability will be dropped in a future release.
|
|
|
|
|
|
:meth:`Page.get_latest_revision_as_page() <wagtail.core.models.Page.get_latest_revision_as_page>` now returns live page object when there are no draft changes
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
If you have any application code that makes direct updates to page data, at the model or database level, be aware that the way these edits are reflected in the page editor has changed.
|
|
|
|
Previously, the ``get_latest_revision_as_page`` method - used by the page editor to return the current page revision for editing - always retrieved data from the page's revision history. Now, it will only do so if the page has unpublished changes (i.e. the page is in ``live + draft`` state) - pages which have received no draft edits since being published will return the page's live data instead.
|
|
|
|
As a result, any changes made directly to a live page object will be immediately reflected in the editor without needing to update the latest revision record (but note, the old behaviour is still used for pages in ``live + draft`` state).
