Из-за чего не работает пользовательская поле модели в django?

Question

[IoannKh]

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:

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

И все миграции успешно применены?

[IoannKh]

Сергей Горностаев, во время последней миграции, когда применяю migrate появляется ошибка (File "/home/ioann/.local/share/virtualenvs/TREANING_FOR_DJANGO-qmgCEbuO/lib/python3.8/site-packages/django/db/backends/sqlite3/base.py", line 357, in execute
return Database.Cursor.execute(self, query, params)
django.db.utils.OperationalError: table new__element_one_finishmodel has no column named root)

[Ищю в поисковиках]

IoannKh, попробуй удалить все миграции из проекта и создать заново.
