According to your reference from https://hackernoon.com/using-enum-as-model-field-choice-in-django-92d8b97aaa63. The choices should be list of tuple, while yours will return a tuple of tuple. More over i is different from i.name. Try:

#enums.py
class TransactionType(Enum):

    IN = "IN",
    OUT = "OUT"

    @classmethod
    def choices(cls):
        return [(i, i.value) for i in cls]
