URL Hooks


URLs added through URL Hooks are protected by a decorator which ensures the requesting user is logged in and has a main character set.

The URL hooks allow you to dynamically specify URL patterns from your plugin app or service. To achieve this you should subclass or instantiate the services.hooks.UrlHook class and then register the URL patterns with the hook.

To register a UrlHook class you would do the following:

def register_urls():
    return UrlHook(app_name.urls, 'app_name', r^'app_name/')

The UrlHook class specifies some parameters/instance variables required for URL pattern inclusion.

UrlHook(urls, app_name, base_url)


The urls module to include. See the Django docs for designing urlpatterns.


The URL namespace to apply. This is usually just the app name.


The URL prefix to match against in regex form. Example r'^app_name/'. This prefix will be applied in front of all URL patterns included. It is possible to use the same prefix as existing apps (or no prefix at all) but standard URL resolution ordering applies (hook URLs are the last ones registered).


An app called plugin provides a single view:

def index(request):
    return render(request, 'plugin/index.html')

The app’s urls.py would look like so:

from django.urls import path
import plugin.views

urlpatterns = [
    path('index/', plugins.views.index, name='index'),

Subsequently it would implement the UrlHook in a dedicated auth_hooks.py file like so:

from alliance_auth import hooks
from services.hooks import UrlHook
import plugin.urls

def register_urls():
    return UrlHook(plugin.urls, 'plugin', r^'plugin/')

When this app is included in the project’s settings.INSTALLED_APPS users would access the index view by navigating to https://example.com/plugin/index.
