to_dict() does not convert enums to strings

As resolved in #51, python enums can be used with dataclasses-json and I have successfully tried that, using the to_json() and from_json() methods.

However, with to_dict(), enum values appear to be untouched, hence the resulting dictionary is not JSON serializable. I assume that this is not the intended behavior, as according to the API docs, to_dict() should return a JSON-compatible dict.

you have to do foo.to_dict(encode_json=True)

I also have this issue with to_json(), which doesn’t have an encode_json parameter. What I ended up doing was

from dataclasses import dataclass, field
from dataclasses_json import DataClassJsonMixin, config
from enum import Enum
class MyEnum(Enum):
    Foo = "foo"
    Bar = "bar"

@dataclass
class Data(DataClassJsonMixin):
    test: MyEnum = field(metadata=config(encoder=lambda x: x.value, decoder=MyEnum))

foo = Data(MyEnum.Foo)
print(foo.to_json())
assert Data.from_json('{"test": "foo"}').test == MyEnum.Foo
