Also, if I use the `schema` decorator and do prints on what schema is being
used in decorators.py in `api_view` (in DRF)
WrappedAPIView.schema = getattr(func, 'schema',
APIView.schema)
print 'WrappedAPIView.schema', WrappedAPIView.schema
print 'getattr schema', getattr(func, 'schema', None)
and in the `schema` decorator
def schema(view_inspector):
print 'view_inspector', view_inspector
def decorator(func):
print 'in decorator'
func.schema = view_inspector
print 'schema is set!', func.schema
return func
return decorator
It correctly accessed my custom schema (not in the post above), but didn't
utilize any of the methods (get_serializer_fields), etc. that were in
there. I believe the __init__ override wasn't even called. (I could be
misunderstanding this part)
