Реализую пользовательскую модель, как написано в документации, но возникает ошибка OperationalError.
Мой код:
class HandField(models.Field):
description = "A hand of cards (bridge style)"
def __init__(self, *args, **kwargs):
kwargs['max_length'] = 104
super().__init__(*args, **kwargs)
def deconstruct(self):
name, path, args, kwargs = super().deconstruct()
del kwargs["max_length"]
return name, path, args, kwargs
class FinishModel(models.Model):
root = HandField()
@admin.register(FinishModel)
class FinishModelAdmin(admin.ModelAdmin):
list_display = ('root',)
Текст ошибки:
OperationalError at /admin/element_one/finishmodel/add/

Миграции есть
class Migration(migrations.Migration):
dependencies = [
('element_one', '0017_remove_finishmodel_root'),
]
operations = [
migrations.AddField(
model_name='finishmodel',
name='root',
field=element_one.models.HandField(default=1),
preserve_default=False,
),
]
В PyCharm ошибка:
return Database.Cursor.execute(self, query, params)
django.db.utils.OperationalError: no such column: element_one_finishmodel.root
