Instructions

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

This is a fork the application "django-taggit-templatetags".

django-taggit-templatetags2 requires Django 1.6 or greater.

The application works well under python 2.7 and 3.x

Installation

Just install django-taggit-templatetags2 via pip:

$ pip install django-taggit-templatetags2

After installing and configuring django-taggit, just add taggit_templatetags2 to your INSTALLED_APPS in your settings.py:

INSTALLED_APPS = (
...
'taggit_templatetags2',
...
)

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_templatetags2_tags:

...
{% load taggit_templatetags2_tags %}
...

Tagdetail

List of tags for the selected object:

{% get_tags_for_object <some_model_object> as "tags" %}

Taglists

After loading taggit_templatetags2_tags 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 a model, just do:

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

You can also customize the name of the tags manager in your model (the default is tags):

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

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: tag cloud

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

{% include_tagcloud 'yourapp.yourmodel' %}

Inclusion-Tag: tag canvas

TagCanvas is a Javascript class which will draw and animate a HTML5 canvas based tag cloud. You can use this library in your application as follows:

<!-- Somewhere before the tag include_tagcanvas. For example, in the "head". -->
{% include "taggit_templatetags2/tagcanvas_include_js_static.html" %}

{% include_tagcanvas 'element_id' 'width px' 'height px' 'some-url-name' 'yourapp.yourmodel' %}

• element_id - name to create identifiers for html tags

• some-url-name - url to view a list of objects for the selected tag. Default: tagcanvas-list.

  For example, some-url-name='myurlname', then it must be an entry in urls.py file like this:

  from taggit_templatetags2.views import TagCanvasListView

  urlpatterns = patterns(

  ... url(r'^tag-list/(?P<tag_id>.*)/(?P<tag_slug>.*)/',

  TagCanvasListView.as_view(), name='myurlname'),

  )

Or you can use the default view, and then you have to add the following things:

• in urls.py:

  from taggit_templatetags2 import urls as taggit_templatetags2_urls
  urlpatterns = patterns(
      ...
      url(r'^tags/', include('taggit_templatetags2.urls')),
  )
  

• override template "taggit_templatetags2/tagcanvas_base.html" and

• override template "taggit_templatetags2/tagcanvas_list_item.html" to customize the look

To use this inclusion-tag, make sure that 'django.core.context_processors.static' appears somewhere in your 'context_processors' settings in your settings.py:

TEMPLATES = [
  {
      'BACKEND': 'django.template.backends.django.DjangoTemplates',
      ...
      'OPTIONS': {
          'context_processors': [
              ...
            'django.core.context_processors.static',
          ]
  }
]

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.

If you're using your own Tag and/or TaggedItem models rather than the default ones (Custom Tagging), you can specify a tuple for each model (app,model_name)

TAGGIT_TAG_MODEL = ('myapp','MyTag')

default: ('taggit', 'Tag')

TAGGIT_TAGGED_ITEM_MODEL = ('myapp','MyTaggedItem')

default: ('taggit', 'TaggedItem')

TAGGIT_LIMIT = 234

Number items for tag cloud. default: 10

TAGGIT_TAG_LIST_ORDER_BY = 'name'

Order for the queryset used to generate the list. default: -num_times

TAGGIT_TAG_CLOUD_ORDER_BY = '-num_times'

Order for the queryset used to generate the list. default: name

Thanks

Thanks to the python- and django-community, in particular to Alex Gaynor, the inventor of django-taggit and a wonderful guy to argue with. Thanks to Mathijs de Bruin as well for his helpful pull requests.
