Django rest framework permission classes8/15/2023 ![]() Note this is similar to Django REST's check_permissions and check_object_permissions but more generic & adjustable since you can have arbitrary number of costs (instead of 2). In this example, roles with cost 0 would be checked first, and lastly the creator role would be checked since it has the highest cost. get_object () if hasattr ( obj, 'creator' ): return request. plan ( cost = 50 ) def is_creator ( request, view ): obj = view. ![]() plan = 'freebie' ( cost = 0 ) def is_payed_user ( request, view ): return request. from rest_framework_corators import role_checker ( cost = 0 ) def is_freebie_user ( request, view ): return request. Less frequent or expensive checks to happen prior to infrequent and slower ones. This decorator takes perm argument (it can be a list or string ). You can change the order of how roles are checked. Django provides a decorator permissionrequired by which we can add a permission layer on a particular view. admin is also a user (unless you change the implementation of is_user and is_admin). Keep in mind that someone can fit multiple roles. It's important to not mix them with the roles though to keeps things clean (1) a role identifies someone making the request while (2) granting determines if the person fitting tha role should be granted permission for their request. You can put all these functions inside a new file granting.py or just keep them close to the views, depending on what makes sense for your case. In the above example the user can only update their information only while not trying to update their email. ![]() The reason models dont enforce permissions is that, normally, the model is.

This makes it easy to switch between this and the normal DRF behaviour depending on your needs. This works as a replacement for permission_classes on individual classes.
