django-activelink is a Django template library for checking whether the current page matches a given URL. It is useful for highlighting active links in menus.
You can install django-activelink from PyPI:
pip install django-activelink
Add activelink to your INSTALLED_APPS:
INSTALLED_APPS = (
...
'activelink',
...
)
Whenever you want to use django-activelink in a template, you need to load its template library:
{% load activelink %}
IMPORTANT: django-activelink requires that the current request object is available in your template's context. This means you must be using a RequestContext when rendering your template, and django.core.context_processors.request must be in your TEMPLATE_CONTEXT_PROCESSORS setting. See the documentation for more information.
Three template tags are provided: ifactive, ifstartswith and ifcontains. These take exactly the same arguments as the built-in url template tag. They check whether the URL provided matches the current request URL. This is easiest to explain with an example:
<a href="{% url "myurl" %}" class="{% ifactive "myurl" %}on{% else %}off{% endifactive %}">Menu item</a>
You can also pass a literal URL rather than a URL name:
<a href="/myurl/" class="{% ifactive "/myurl/" %}on{% else %}off{% endifactive %}">Menu item</a>
The ifstartswith tag checks whether the beginning of the current URL matches. This is useful for top-level menu items with submenus attached.
The ifcontains tag checks that the current URL contains the searched part.
Note: Django 1.3 started the process of gradually deprecating the existing url template tag and replacing it with a new one, which requires literal string arguments to be quoted. See the release notes for more information. To be forwards-compatible, django-activelink only supports the new version of the syntax. You can still use it in templates using the old version, but you have to remember to quote your strings properly.
