I have installed marshmallow-dataclass[enum,union] as per the instructions.
But when I try to validate a dataclass using an Enum/EnumField type, the validation fails.
Using marshmallow Schema directly works:
from dataclasses import dataclass
from enum import Enum
from marshmallow import Schema
from marshmallow_enum import EnumField
import marshmallow_dataclass
class RuleSchema(Schema):
class Action(Enum):
READ = "read"
WRITE = "write"
action = EnumField(Action, by_value=True)
# Works
print(RuleSchema().validate({"action": RuleSchema.Action.READ}))
Using marshmallow_dataclass.class_schema fails:
@dataclass
class Rule:
class Action(Enum):
READ = "read"
WRITE = "write"
action: Action = EnumField(Action, by_value=True)
# outputs as expected: {'action': 'READ'}
print(marshmallow_dataclass.class_schema(Rule)().dump({"action": Rule.Action.READ}))
# Fails validation with: {'action': ['Not a valid string.']}
print(marshmallow_dataclass.class_schema(Rule)().validate({"action": Rule.Action.READ}))
After looking through previous issues and code and seeing mentions of the switch from marshmallow_enum to the native marshmallow type, I updated the code accordingly and still getting the same problem.
