Wagtail is now compatible with Django 1.9.


Indexing fields across relations in Elasticsearch

class Book(models.Model, index.Indexed):
    ...

    search_fields = [
        index.SearchField('title'),
        index.FilterField('published_date'),

        index.RelatedFields('author', [
            index.SearchField('name'),
            index.FilterField('date_of_birth'),
        ]),
    ]

# Search books where their author was born after 1950
# Both the book title and the author's name will be searched
>>> Book.objects.filter(author__date_of_birth__gt=date(1950, 1, 1)).search("Hello")

The search interface in the Wagtail admin now includes a toolbar to quickly switch between different search types - pages, images, documents and users. A new :ref:`register_admin_search_area <register_admin_search_area>` hook is provided for adding new search types to this toolbar.

Upgrade considerations
======================

Jinja2 template tag modules have changed location

TEMPLATES = [
    # ...
    {
        'BACKEND': 'django.template.backends.jinja2.Jinja2',
        'APP_DIRS': True,
        'OPTIONS': {
            'extensions': [
                'wagtail.core.jinja2tags.core',
                'wagtail.wagtailadmin.jinja2tags.userbar',
                'wagtail.wagtailimages.jinja2tags.images',
            ],
        },
    }
]

The following internal functions and methods in ``wagtail.wagtailcore.models``, which return a list of ``ContentType`` objects, have been deprecated. Any uses of these in your code should be replaced by the corresponding new function which returns a list of model classes instead:

* ``get_page_types()`` - replaced by ``get_page_models()``
* ``Page.clean_subpage_types()`` - replaced by ``Page.clean_subpage_models()``
* ``Page.clean_parent_page_types()`` - replaced by ``Page.clean_parent_page_models()``
* ``Page.allowed_parent_page_types()`` - replaced by ``Page.allowed_parent_page_models()``
* ``Page.allowed_subpage_types()`` - replaced by ``Page.allowed_subpage_models()``

In addition, note that these methods now return page types that are marked as ``is_creatable = False``, including the base ``Page`` class. (Abstract models are not included, as before.)
