Usage

Tags

First load the tags inside whatever templates you are going to use them:

{% load templateutils_tags %}

active_url

Returns a class to be assiged CSS styling that should make the chosen element highlighted as responsible of being in the active url.

Example: Assuming that the reversed url is the current url, this tag will act as follows:

{% active_url request url_name %} -> class="ui-active-url"
{% active_url request url_name class_name=myclass %} -> class="myclass"
{% active_url request url_name use_class=False %} -> ui-active-url
{% active_url request url_name class_name=myclass use_class=False %} -> myclass

Where urlname is the name of the url to check; this must be defined in your URLCONF, otherwise it will raise a NoReverseMatch Error.

current_url

Returns the reversed url only if it is NOT the current url. Otherwise returns the character "#"

Example:

<a href="{% current_url request url_name %}">Some link</a>

Checks if the current user belongs to a specific group.

• User must be looged in.
• Requires the Django authentication contrib app and middleware.

Usage:

{% ifmember Admins %} ... {% endifusergroup %}
