Example::
class MyModel(models.Model):
DIRECTION_UP = "U"
DIRECTION_DOWN = "D"
DIRECTION_CHOICES = [
(DIRECTION_UP, "Up"),
(DIRECTION_DOWN, "Down"),
]
DIRECTION_CHOICES = {
DIRECTION_UP: "Up",
DIRECTION_DOWN: "Down",
}
Alternatively, consider using :ref:`field-choices-enum-types`::
class MyModel(models.Model):
class Direction(models.TextChoices):
UP = U, "Up"
DOWN = D, "Down"
