Dumpscript serializes enumfields.Enum incorrectly

[DanLipsitt]

Enum fields made with django-enumfields serialize incorrectly as __repr__-like strings.

Model

import enumfields

class Action(enumfields.Enum):
    LIST = 'list'

class Permission(models.model):
   action = enumfields.EnumField(Action, max_length=30)

manage.py dumpscript output (incorrect)

app_permission_1 = UserCategoryPermission()
app_permission_1.action = <Action.LIST: 'list'>

yaml manage.py dumpdata output (correct)

- model: app.permission
  pk: 1
  fields:
    action: list
