Enumerator JSON serialization broken when using enumerated classes

[madsmtm]

Title mostly speaks for itself, the JSON serializer can't handle enum.Enum types, which you (can) use in sqlalchemy.types.Enum

Example code is here

Traceback:

Thanks for the detailed report! Do you have time to give this a shot?

Your example looks like a good starting point for an integration test in the spirit of collection_class_set.py (including POST and PATCH requests). For the fix itselt take a look at _sanitize_value in utils.py.

Thanks for the quick response, but no, currently I don't have the time, I might get around to looking into it, but don't count on it 😉
