Python 3 compatible ratings for Django.

Add ratings to any Django model with a template tag.

See full documentation.


  • Python 3.6+.
  • Django 2.0+


Install from PyPI:

pip install django-star-ratings

add star_ratings to INSTALLED_APPS:


sync your database:

python migrate

add the following to your

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

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


Add the following javascript and stylesheet to your template

{% load static %}
<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>

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

{% load ratings %}
{% ratings object %}

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


To prohibit users from altering their ratings set STAR_RATINGS_RERATE = False in

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')


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 []).

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:


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

And add the setting to the setting file:



NOTE: If you are using a custom rating model there is an issue with how django migration handles dependency orders. In order to create your initial migration you will need to comment out the STAR_RATINGS_RATING_MODEL setting and run makemigrations. After this initial migration you will be able to add the setting back in and run migrate and makemigrations without issue.

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 well as set STAR_RATINGS_OBJECT_ID_PATTERN to a reasonable value for your new pk field. 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)

And add the setting to the setting file:




Some events are dispatched from the javascript when an object is raised. Each event that ias dispatched has a details property that contains information about the object and the rating.


Dispatched after the user has rated an object and the display has been updated.

The event details contains

    sender: ... // The star DOM object that was clicked
    rating: {
        average: ... // Float giving the updated average of the rating
        count: ... // Integer giving the total number of ratings
        percentage: ... // Float giving the percentage rating
        total: ... // Integer giving the sum of all ratings
        user_rating: ... // Integer giving the rating by the user


Dispatched after the user has rated an object but the server responds with an error.

The event details contains

    sender: ... // The star DOM object that was clicked
    error: ... // String giving the error message from the server

Running tests

To run the test use:

$> ./


Travis is setup to push releases to pypi automatically on tags, to do a release:

  1. Up version number.
  2. Update release notes.
  3. Push dev.
  4. Merge develop into master.
  5. Tag with new version number.
  6. Push tags.
