Discriminate which user can vote

[Alejoss]

Hi all. I think there is a very important use case that is not addressed by this lbry, how can one discriminate which user can vote? In my case, I need to make sure only users with a "certificate" can vote on the course rating (other users haven't taken the course, they shouldn't be able to vote). How can I achieve that, the template tag doesn't receive any useful argument for this. There is an editable template variable but no docs on how/where to set it to false.

Hi @Alejoss

Thanks for the report, that does sound like a useful feature to add.

I think it could be answered a couple of ways, either via overriding editable in the template to check for a permission, or perhaps a more generic solution would be to amend how editable is used within ratings.py

django-star-ratings/star_ratings/templatetags/ratings.py

Line 57 in 3495eaa

'editable': not read_only and (is_authenticated(request.user) or app_settings.STAR_RATINGS_ANONYMOUS),

Adding a variable along the lines of STAR_RATINGS_PERMISSIONS_CHECK to allow users to specify a path to a function that takes a user and checks permissions (falling back to is_authenticated).

If this is something you are looking into we'd be happy to accept a PR.

Thanks
