Rated reviews application for Django

Rated reviews is derived from Django “excontrib” Comments and can be used to attach reviews with rating to any model. The core difference from comments is that user can provide only one review per item. Rating is expressed by a number and by default visualized with stars. However, it can be changed to whatever you want. Rating grades are also configurable.

Optionally rating can be weighted. For instance, you can designate experts whose rating would be more valuable. Alternatively, add weight to reviews of real byers of sold product.

Documentation is published on Read the Docs.

Requirements

• Python 2.7+ or Python 3.3+

Installation

Install django-rated-reviews using pip:

pip install django-rated-reviews

Add reviews to INSTALLED_APPS. Example:

INSTALLED_APPS = (
    ...
    'reviews',

    ...
]

Use the review template tags to embed reviews in your templates.

        count = Order.objects.filter(user=user.pk,
                                     item__product=target.pk,
                                     status=Order.STATUS_DONE
                                     ).count()
