.. _routable_page_mixin:
|
|
|
|
====================================
|
|
Embedding URL configuration in Pages
|
|
====================================
|
|
|
|
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 ``BlogIndex`` page.
|
|
|
|
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, using Django's urlconf scheme. 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`, and configure the ``subpage_urls`` attribute with your URL configuration.
|
|
|
|
Here's an example of an ``EventPage`` with three views:
|
|
|
|
.. code-block:: python
|
|
|
|
from django.conf.urls import url
|
|
|
|
from wagtail.contrib.wagtailroutablepage.models import RoutablePageMixin
|
|
from wagtail.wagtailcore.models import Page
|
|
|
|
|
|
class EventPage(RoutablePageMixin, Page):
|
|
subpage_urls = (
|
|
url(r'^$', 'current_events', name='current_events'),
|
|
url(r'^past/$', 'past_events', name='past_events'),
|
|
url(r'^year/(\d+)/$', 'events_for_year', name='events_for_year'),
|
|
)
|
|
|
|
def current_events(self, request):
|
|
"""
|
|
View function for the current events page
|
|
"""
|
|
...
|
|
|
|
def past_events(self, request):
|
|
"""
|
|
View function for the past events page
|
|
"""
|
|
...
|
|
|
|
def events_for_year(self, request):
|
|
"""
|
|
View function for the events for year page
|
|
"""
|
|
...
|
|
|
|
|
|
The ``RoutablePageMixin`` class
|
|
===============================
|
|
|
|
.. automodule:: wagtail.contrib.wagtailroutablepage.models
|
|
.. autoclass:: RoutablePageMixin
|
|
|
|
.. autoattribute:: subpage_urls
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
from django.conf.urls import url
|
|
|
|
from wagtail.wagtailcore.models import Page
|
|
|
|
|
|
class MyPage(RoutablePageMixin, Page):
|
|
subpage_urls = (
|
|
url(r'^$', 'main', name='main'),
|
|
url(r'^archive/$', 'archive', name='archive'),
|
|
url(r'^archive/(?P<year>[0-9]{4})/$', 'archive', name='archive'),
|
|
)
|
|
|
|
def main(self, request):
|
|
...
|
|
|
|
def archive(self, request, year=None):
|
|
...
|
|
|
|
.. automethod:: resolve_subpage
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
view, args, kwargs = page.resolve_subpage('/archive/')
|
|
response = view(request, *args, **kwargs)
|
|
|
|
.. automethod:: reverse_subpage
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
url = page.url + page.reverse_subpage('archive', 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 self "feed" %}
|
|
{% routablepageurl self "archive" 2014 08 14 %}
|
|
{% routablepageurl self "food" foo="bar" baz="quux" %}
