I have the following model:
{{{
class Question(models.Model):
@enum.unique
class MODE(enum.IntEnum):
TEXT = 1
NUMBER = 2
CHOICE = 3
question = models.TextField()
label_text = models.CharField(max_length=200)
hint = models.CharField(max_length=200, blank=True)
mode = models.IntegerField(
default=MODE.TEXT,
choices=((x.value, x.name.title()) for x in MODE),
)
}}}
The initial migration generated produces:
{{{
migrations.CreateModel(
name='Question',
fields=[
('id', models.AutoField(auto_created=True,
primary_key=True, serialize=False, verbose_name='ID')),
('question', models.TextField()),
('label_text', models.CharField(max_length=200)),
('hint', models.CharField(blank=True, max_length=200)),
('mode', models.IntegerField(choices=[(1, 'Text'), (2,
'Number'), (3, 'Choice')], default=sheets.models.MODE(1))),
],
),
}}}
Notice the default... it's sheets.models.MODE instead of
sheets.models.Question.MODE
This causes the following traceback:
{{{
