coop-tag 0.2.1

coop-tag
========

An app for managing tags largely built on `django-taggit <http://github.com/quinode/django-taggit>`_
We integrated in this package two other add-ons for taggit :
- `django-taggit-autosuggest <https://bitbucket.org/quinode/django-taggit-autosuggest>`_
- `django-taggit-templatetags <https://github.com/quinode/django-taggit-templatetags>`_

So we have a nice styled autocomplete widget and some templatetags to use taggit.
Tag slugs are unicode-friendly. That means accented letters are valid URI characters (like they should be !)
So you can have differents slugs for differents tags.

Installation and dependencies::
$ pip install git+git://github.com/quinode/django-templatetag-sugar.git
$ pip install django-autoslug
$ pip install unicode-slugify
$ pip install coop_tag

Add `coop_tag` (with an underscore) to INSTALLED_APPS in your django project settings.
Run `python manage.py collectstatic` in your django project directory.
Add the following line a the bottom of your project's urls.py file::
(r'^', include('coop_tag.urls')),


Usage
=====

To enable Tags, just let the tagged model use the TaggableManager::

from django.db import models
from coop_tag.managers import TaggableManager

class SomeModel(models.Model):
...
tags = TaggableManager(help_text="your optional help text", blank=True,)

If you want to leverage Generic Relations, you can use a `through` model::

from coop_tag.managers import TaggableManager
from coop_tag.models import TaggedItem

class SomeModel(models.Model):
tags = TaggableManager(through=TaggedItem, blank=True,)

The Tag model and the optional TaggedItem model are configurable, you can use your owns (see seetings above)

You can use the great taggit API like so::

>>> apple = Food.objects.create(name="apple")
>>> apple.tags.add("red", "green", "delicious")
>>> apple.tags.all()
[<Tag: red>, <Tag: green>, <Tag: delicious>]
>>> apple.tags.remove("green")
>>> apple.tags.all()
[<Tag: red>, <Tag: delicious>]
>>> Food.objects.filter(tags__name__in=["red"])
[<Food: apple>, <Food: cherry>]

Tags will show up for you automatically in forms and the admin.


Template tags
=============

Fork of `django-taggit-templatetags`, a reusable django app which adds some templatetags to django-taggit_.
This particular fork uses a fork of django-templatetag-sugar_, by Jonas Geiregat, only this version allows us to give multiples arguments to a templatetag.

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 ``tagger_extras``::

...
{% load tagger_extras %}
...

--------
Taglists
--------

After loading ``tagger_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 asvar tags %}

To limit the number of tags::

{% get_taglist asvar tags count 25 %}

For the tags of an app, just do::

{% get_taglist asvar tags for_obj 'yourapp' %}

For the tags of a model, just do::

{% get_taglist asvar tags for_obj 'yourapp.yourmodel' %}

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

{% get_taglist asvar tags for_obj '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 id="tags" class="indextags">
{% get_taglist asvar all_tags for_obj target_app count 15 %}
{% for tag in all_tags %}
<li class="tag">
<a href="{{ tag.get_absolute_url }}">{{tag}} ({{tag.num_times}})</a>
</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 in Tagcloud
-------------------------

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

{% include_tagcloud 'yourapp.yourmodel' %}

.. _settings:

Optional Settings
=================

TAGGER_TAG_MODEL (Defaults to 'coop_tag.models.Tag')
The Tag model used, if you happen to use a custom model.
TAGGER_TAGGEDITEM_MODEL (Defaults to 'coop_tag.models.TaggedItem')
The Taggeditem model used, if you happen to use a custom model.
TAGGER_FKEY_NAME (Defaults to 'coop_local.Tag')
The linked model on the through model can also be customized (use only if you have the two settings above set)

TAGGER_STATIC_URL:
Instead of collecting and serving the static files directly, you can also set this variable to your static base URL somewhere else.
TAGGER_CSS_FILENAME (Defaults to 'coop_tag.css'):
Set the CSS file which best fits your site elements.
TAGGER_MAX_SUGGESTIONS (Defaults to 20):
The amount of suggestions is limited, you can raise or lower the limit of default 20 using this setting
TAGGER_CLOUD_MIN (default: 1.0)
This specifies the minimum of the weight attribute of a tagcloud's tags.
TAGGER_CLOUD_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.
