``RoutablePageMixin``
|
|
=====================
|
|
|
|
.. module:: wagtail.contrib.wagtailroutablepage
|
|
|
|
The ``RoutablePageMixin`` mixin provides a convenient way for a page to respond on multiple sub-URLs with different views. For example, a blog section on a site might provide several different types of index page at URLs like ``/blog/2013/06/``, ``/blog/authors/bob/``, ``/blog/tagged/python/``, all served by the same page instance.
|
|
|
|
A ``Page`` using ``RoutablePageMixin`` exists within the page tree like any other page, but URL paths underneath it are checked against a list of patterns. If none of the patterns match, control is passed to subpages as usual (or failing that, a 404 error is thrown).
|

|
Installation
|
|
============
|
|
|
|
Add ``"wagtail.contrib.wagtailroutablepage"`` to your INSTALLED_APPS:
|
|
|
|
.. code-block:: python
|
|
|
|
INSTALLED_APPS = [
|
|
...
|
|
|
|
"wagtail.contrib.wagtailroutablepage",
|
|
]
|
|
|
|
|
|
The basics
|
|
==========
|
|
|
|
To use ``RoutablePageMixin``, you need to make your class inherit from both :class:`wagtail.contrib.wagtailroutablepage.models.RoutablePageMixin` and :class:`wagtail.wagtailcore.models.Page`, then define some view methods and decorate them with ``wagtail.contrib.wagtailroutablepage.models.route``.
|
|
|
|
Here's an example of an ``EventPage`` with three views:
|
|
|
|
.. code-block:: python
|
|
|
|
from wagtail.wagtailcore.models import Page
|
|
from wagtail.contrib.wagtailroutablepage.models import RoutablePageMixin, route
|
|
|
|
|
|
class EventPage(RoutablePageMixin, Page):
|
|
...
|
|
|
|
@route(r'^$')
|
|
def current_events(self, request):
|
|
"""
|
|
View function for the current events page
|
|
"""
|
|
...
|
|
|
|
@route(r'^past/$')
|
|
def past_events(self, request):
|
|
"""
|
|
View function for the past events page
|
|
"""
|
|
...
|
|
|
|
# Multiple routes!
|
|
@route(r'^year/(\d+)/$')
|
|
@route(r'^year/current/$')
|
|
def events_for_year(self, request, year=None):
|
|
"""
|
|
View function for the events for year page
|
|
"""
|
|
...
|
|
|
|
Reversing URLs
|
|
==============
|
|
|
|
:class:`~models.RoutablePageMixin` adds a :meth:`~models.RoutablePageMixin.reverse_subpage` method to your page model which you can use for reversing URLs. For example:
|
|
|
|
.. code-block:: python
|
|
|
|
# The URL name defaults to the view method name.
|
|
>>> event_page.reverse_subpage('events_for_year', args=(2015, ))
|
|
'year/2015/'
|
|
|
|
This method only returns the part of the URL within the page. To get the full URL, you must append it to the values of either the :attr:`~wagtail.wagtailcore.models.Page.url` or the :attr:`~wagtail.wagtailcore.models.Page.full_url` attribute on your page:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> event_page.url + event_page.reverse_subpage('events_for_year', args=(2015, ))
|
|
'/events/year/2015/'
|
|
|
|
>>> event_page.full_url + event_page.reverse_subpage('events_for_year', args=(2015, ))
|
|
'http://example.com/events/year/2015/'
|
|
|
|
Changing route names
|
|
--------------------
|
|
|
|
The route name defaults to the name of the view. You can override this name with the ``name`` keyword argument on ``@route``:
|
|
|
|
.. code-block:: python
|
|
|
|
from wagtail.wagtailcore.models import Page
|
|
from wagtail.contrib.wagtailroutablepage.models import RoutablePageMixin, route
|
|
|
|
|
|
class EventPage(RoutablePageMixin, Page):
|
|
...
|
|
|
|
@route(r'^year/(\d+)/$', name='year')
|
|
def events_for_year(self, request, year):
|
|
"""
|
|
View function for the events for year page
|
|
"""
|
|
...
|
|
|
|
.. code-block:: python
|
|
|
|
>>> event_page.reverse_subpage('year', args=(2015, ))
|
|
'/events/year/2015/'
|
|
|
|
The ``RoutablePageMixin`` class
|
|
===============================
|
|
|
|
.. automodule:: wagtail.contrib.wagtailroutablepage.models
|
|
.. autoclass:: RoutablePageMixin
|
|
|
|
.. automethod:: get_subpage_urls
|
|
|
|
.. automethod:: resolve_subpage
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
view, args, kwargs = page.resolve_subpage('/past/')
|
|
response = view(request, *args, **kwargs)
|
|
|
|
.. automethod:: reverse_subpage
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
url = page.url + page.reverse_subpage('events_for_year', kwargs={'year': '2014'})
|
|
|
|
|
|
.. _routablepageurl_template_tag:
|
|
|
|
The ``routablepageurl`` template tag
|
|

|
|
|
.. currentmodule:: wagtail.contrib.wagtailroutablepage.templatetags.wagtailroutablepage_tags
|
|

|
|
|

|
|
|
|
.. code-block:: html+django
|

|
|
|
{% routablepageurl page "feed" %}
|
|
{% routablepageurl page "archive" 2014 08 14 %}
|
