"""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)
|
|
