Project description

django-star-ratings
===================

|Build Status| |codecov.io| |Documentation Status|

Python 3 compatible ratings for Django.

Add ratings to any Django model with a template tag.

See full `documentation
<http://django-star-ratings.readthedocs.io/en/latest/?badge=latest/>`_.

Installation
------------

Install from PyPI:

::

pip install django-star-ratings

add ``star_ratings`` to ``INSTALLED_APPS``:

::

INSTALLED_APPS = (
...
'star_ratings'
)

sync your database:

::

python manage.py migrate

add the following to your urls.py:

::

url(r'^ratings/', include('star_ratings.urls', namespace='ratings', app_name='ratings')),

Make sure ``'django.core.context_processors.request',`` is in
``TEMPLATE_CONTEXT_PROCESSORS``.

Usage
-----

Add the following javascript and stylesheet to your template

::

{% load static %}
<html>
...
<link rel="stylesheet" href="{% static 'star-ratings/css/star-ratings.css' %}">
<script type="text/javascript" src="{% static 'star-ratings/js/dist/star-ratings.min.js' %}"></script>
...
</html>

To enable ratings for a model add the following tag in your template

::

{% load ratings %}
<html>
...
{% ratings object %}
...
</html>

Template tags
-------------

The template tag takes four arguments:

- ``icon_height``: defaults to ``STAR_RATINGS_STAR_HEIGHT``
- ``icon_width``: defaults to ``STAR_RATINGS_STAR_WIDTH``
- ``read_only``: overrides the ``editable`` behaviour to make the widget read only
- ``template_name``: overrides the tempalte to use for the widget

Settings
--------

To prohibit users from altering their ratings set
``STAR_RATINGS_RERATE = False`` in settings.py

To change the number of rating stars, set ``STAR_RATINGS_RANGE``
(defaults to 5)

To enable anonymous rating set ``STAR_RATINGS_ANONYMOUS = True``.

Anonymous Rating
----------------

If anonymous rating is enabled only the ip address for the rater will be stored (even if the user is logged in).
When a user rates an object a preexisting object will not be searched for, instead a new rating object will be created

**If this value is changed your lookups will return different results!**

To control the default size of stars in pixels set the values of ``STAR_RATINGS_STAR_HEIGHT`` and
``STAR_RATINGS_STAR_WIDTH``. By default ``STAR_RATINGS_STAR_WIDTH`` is the same as
``STAR_RATINGS_STAR_HEIGHT`` and ``STAR_RATINGS_STAR_HEIGHT`` defaults to 32.


Changing the star graphics
--------------------------

To change the star graphic, add a sprite sheet to
``/static/star-ratings/images/stars.png`` with the states aligned
horizontally. The stars should be laid out in three states: full, empty
and active.

You can also set ``STAR_RATINGS_STAR_SPRITE`` to the location of your sprite sheet.

Customize widget template
-------------------------

You can customize ratings widget by creating ``star_ratings/widget.html``. For example :

::

{% extends "star_ratings/widget_base.html" %}
{% block rating_detail %}
Whatever you want
{% endblock %}

See ``star_ratings/widget_base.html`` for other blocks to be extended.

Ordering by ratings
-------------------

The easiest way to order by ratings is to add a ``GenericRelation`` to
the ``Rating`` model from your model:

::

from django.contrib.contenttypes.fields import GenericRelation
from star_ratings.models import Rating

class Foo(models.Model):
bar = models.CharField(max_length=100)
ratings = GenericRelation(Rating, related_query_name='foos')

Foo.objects.filter(ratings__isnull=False).order_by('ratings__average')

Custom Rating Model
-------------------

In some cases you may need to create your own rating model. This is possible
by setting ``STAR_RATING_RATING_MODEL`` in your settings file. This can be useful
to add additional fields or methods to the model. This is very similar to the how
django handles swapping the user model
(see [https://docs.djangoproject.com/en/1.10/topics/auth/customizing/#substituting-a-custom-user-model]).

For ease ``AbstractBaseRating`` is supplied. For example if you wanted to add the
field ``foo`` to the rating model you would need to crate your rating model
extending ``AbstractBaseRating``:

::

./myapp/models.py

class MyRating(AbstractBaseRating):
foo = models.TextField()

And add the setting to the setting file:

::

./settings.py

...
STAR_RATINGS_RATING_MODEL = 'myapp.MyRating'
...

Changing the ``pk`` type (Requires django >= 1.10)
==================================================

One use case for changing the rating model would be to change the pk type of the
related object. By default we assume the pk of the rated object will be a
positive integer field which is fine for most uses, if this isn't though you will
need to override the ``object_id`` field on the rating model. As of django 1.10
you can now hide fields form parent abstract models, so to change the ``object_id``
to a ``CharField`` you can do something like:

::

class MyRating(AbstractBaseRating):
object_id = models.CharField(max_length=10)


Running tests
-------------

To run the test use:

::

$> ./runtests.py
