TextChoicesFlag

[Confidenceman02]

Django model CharField's can have a text_choices set in the config to narrow an arbitrary string to a specific one.

Text choices are commonly sub classes like the following:

class Vehicle(models.TextChoices):
     CAR = "C"
     TRUCK = "T"
     JET_SKI = "J"

It would be handy to provide a Djelm analogue to this class and produce a CustomType:

type Vehicle
    = Car String
    | Truck String
    | Jet_ski String
