.. _routable_page_mixin:
=====================
``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).
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
.. autofunction:: routablepageurl
Example:
.. code-block:: html+django
{% load wagtailroutablepage_tags %}
{% routablepageurl page "feed" %}
{% routablepageurl page "archive" 2014 08 14 %}
{% routablepageurl page "food" foo="bar" baz="quux" %}
