How to use enums as a choice field in django model

Question

I have a model class of which I want two fields to be a choice fields, so to populate those choices I am using an enum as listed below

#models.py
class Trans         


        

Answer 1

Problem in your code is that INITIATED = "INITIATED", a comma after INITIATED option and other options. when we add comma after any string it will become a tuple. See an example below

s = 'my str'
print(type(s))
# output: str

s = 'my str',
print(type(s))
# output: tuple

models.py

class Transaction(models.Model):
    trasaction_status = models.CharField(max_length=255, choices=TransactionStatus.choices())
    transaction_type = models.CharField(max_length=255, choices=TransactionType.choices())

enums.py

class TransactionType(Enum):

    IN = "IN"
    OUT = "OUT"

    @classmethod
    def choices(cls):
        print(tuple((i.name, i.value) for i in cls))
        return tuple((i.name, i.value) for i in cls)

class TransactionStatus(Enum):

    INITIATED = "INITIATED"
    PENDING = "PENDING"
    COMPLETED = "COMPLETED"
    FAILED = "FAILED"
    ERROR = "ERROR"

    @classmethod
    def choices(cls):
        print(tuple((i.name, i.value) for i in cls))
        return tuple((i.name, i.value) for i in cls)
