30902	The value of a TextChoices/IntegerChoices field has a differing type	Mikail	nobody	"If we create an instance of a model having a `CharField` or `IntegerField` with the keyword `choices` pointing to `IntegerChoices` or `TextChoices`, the value returned by the getter of the field will be of the same type as the one created by `enum.Enum` (enum value).

For example, this model:

{{{#!python

from django.db import models
from django.utils.translation import gettext_lazy as _


class MyChoice(models.TextChoices):
    FIRST_CHOICE = ""first"", _(""The first choice, it is"")
    SECOND_CHOICE = ""second"", _(""The second choice, it is"")


class MyObject(models.Model):
    my_str_value = models.CharField(max_length=10, choices=MyChoice.choices)
}}}


Then this test:
{{{#!python

from django.test import TestCase
from testing.pkg.models import MyObject, MyChoice


class EnumTest(TestCase):
    def setUp(self) -> None:
        self.my_object = MyObject.objects.create(my_str_value=MyChoice.FIRST_CHOICE)

    def test_created_object_is_str(self):
        my_object = self.my_object
        self.assertIsInstance(my_object.my_str_value, str)
        self.assertEqual(str(my_object.my_str_value), ""first"")

    def test_retrieved_object_is_str(self):
        my_object = MyObject.objects.last()
        self.assertIsInstance(my_object.my_str_value, str)
        self.assertEqual(str(my_object.my_str_value), ""first"")
}}}

And then the results:
{{{

We notice when invoking `__str__(...)` we don't actually get the `value` property of the enum value which can lead to some unexpected issues, especially when communicating to an external API with a freshly created instance that will send `MyEnum.MyValue`, and the one that was retrieved would send `my_value`.
