django-taggit-templatetags

============ Instructions

This is a reusable django app which adds some templatetags to django-taggit_.

Installation

Just install django-taggit-templatetags via pip::

$ pip install django-taggit-templatetags

After installing and configuring django-taggit_, just add taggit_templatetags to your INSTALLED_APPS in your settings.py::

INSTALLED_APPS = (
...
'taggit_templatetags',
...
)

Usage

Now there are some templatetags enabled, at the moment only to create lists of tags and tag-clouds.

In your templates, you need to load taggit_extras::

...
{% load taggit_extras %}
... 

Taglists

After loading taggit_extras you can create a list of tags for the whole project (in the sense of djangoproject), for an app (in the sense of djangoapp), for a model-class (to get a list for an instance of a model, just use its tag-field).

For the tags of a project, just do::

{% get_taglist as tags %}

For the tags of an app, just do::

{% get_taglist as tags for 'yourapp' %}

For the tags of an model, just do::

{% get_taglist as tags for 'yourapp.yourmodel' %}

No matter what you do, you have a list of tags in the tags template variable. You can now iterate over it::

<ul>
{% for tag in tags %}
<li>{{tag}} ({{tag.num_times}})</li>
{% endfor %} 
<ul>

As you can see, each tag has an attribute num_times which declares how many times it was used. The list of tags is sorted descending by num_times.

Inclusion-Tag

For convenience, there's an inclusion-tag. It's used analogue. For example, for a taglist of a model, just do::

{% include_taglist 'yourapp.yourmodel' %}

Tagclouds

A very popular way to navigate through tags is a tagcloud_. This app provides some tags for that::

{% get_tagcloud as tags %}

or::

{% get_tagcloud as tags for 'yourapp' %}

or::

{% get_tagcloud as tags for 'yourapp.yourmodel' %}

respectivly. The resulting list of tags is ordered by their name attribute. Besides the num_items attribute, there's a weight attribute. Its maximum and minimum may be specified as the settings_ section reads.

Inclusion-Tag

Even for the tagcloud there's an inclusion-tag. For example, for a tagcloud of a model, just do::

{% include_tagcloud 'yourapp.yourmodel' %}

.. _settings:

Settings

There are a few settings to be set:

TAGGIT_TAGCLOUD_MIN (default: 1.0) This specifies the minimum of the weight attribute of a tagcloud's tags.

TAGGIT_TAGCLOUD_MAX (default: 6.0) This specifies the maximum of the weight attribute of a tagcloud's tags.

If you want to use the weight as font-sizes, just do as follows::

<font size={{tag.weight|floatformat:0}}>{{tag}}</font> 

So the weights are converted to integer values.

Thanks to the python- and django-community, in particular to Alex Gaynor, the inventor of django-taggit and a wonderful guy to argue with.
