I have a probleme to link my django application to my postgresql database. I have create a custom type currencies in postgresql and I use it as an array.

// Type
create type currencies as enum ('EUR');

// Usage
currencies currencies[] not null

In Django, I have made a Enum Currencies ans try to use it as a choices in a Charfield with no succes using the doc..
The django doc about Arrayfield

class Currencies(models.TextChoices):
    EURO = 'EUR', 'euro'

from django.contrib.postgres.fields import ArrayField

currencies = ArrayField(
    base_field=models.CharField(
        choices=Currencies.choices,
        max_length=3
    ),
    default=list
)
