Api permissions

Permission classes to be used within ninja-extra controllers.

Some permissions are global (like IsInGroup or IsRoot), and some others are per-object (like CanView or CanEdit).

Examples:

restrict all the routes of this controller

to subscribed users

@api_controller("/foo", permissions=[IsSubscriber]) class FooController(ControllerBase): @route.get("/bar") def bar_get(self): # This route inherits the permissions of the controller # ...

@route.bar("/bar/{bar_id}", permissions=[CanView])
def bar_get_one(self, bar_id: int):
    # per-object permission resolution happens
    # when calling either the `get_object_or_exception`
    # or `get_object_or_none` method.
    bar = self.get_object_or_exception(Counter, pk=bar_id)

    # you can also call the `check_object_permission` manually
    other_bar = Counter.objects.first()
    self.check_object_permissions(other_bar)

    # ...

# This route is restricted to counter admins and root users
@route.delete(
    "/bar/{bar_id}",
    permissions=[IsRoot | IsInGroup(settings.SITH_GROUP_COUNTER_ADMIN_ID)
]
def bar_delete(self, bar_id: int):
    # ...

IsInGroup(group_pk)
