Description

Currently it is not possible to use instances of PermissionClasses, leading to lots of boilerplate.

Usecase: I want to check for specific features, like this:
@strawberry.field(permission_classes=[FeatureRequired(feature_1), FeatureRequired(feature_2)]

This does not work, because permission_classes only takes classes and will be instanciated here.

To "fix" this the Typing must be fixed List[Type[BasePermission]] to something like List[Type[BasePermission] | BasePermission]]
and the code snippet here:

permission_instances = [
  permission_class() for permission_class in permission_classes
]

needs some inspection like this:

permission_instances = list()
for permission_class in permission_classes:
  if isinstance(permission_class, type):
    permission_class = permission_class()
  permission_instances.append(permission_instance)

with this changes I also would suggest to refactor the permission_classes name to permissions + deprecating the permission_classes argument on strawberry.field
