django-friendly-tag-loader 1.1

Installation

Add friendlytagloader to INSTALLED_APPS

Usage

{% load friendly_loader %} in your template

Load some optional taglib {% friendly_load comments %}

Conditionally use its tag:

{% if_has_tag render_comment_list %}
    {% render_comment_list for obj %}
{% else %}
    Comment support is not available
{% endif_has_tag %}

{% friendly_load %} takes multiple arguments, so loading multiple optional template tag libraries at once is supported:

{% friendly_load comments webdesign website_tags %}

{% if_has_tag %} and {% ifnot_has_tag %} can also handle multiple arguments.

In the case of if_has_tag this means that all given tags should be available, so this will render nothing even though now is a built-in tag:

{% if_has_tag now nonexisting_tag %}
  {% now 'Y' %}
{% endif_has_tag %}

The ifnot_has_tag condition will trigger if any of the given tags is unavailable. For example this will render the message since, even though now is a built-in tag, nonexisting_tag is not available:

{% ifnot_has_tag now nonexisting_tag %}
  Some tags are unavailable.
{% endifnot_has_tag %}
