Migration tries to set callable object repr as column default in SQL, fails

[artem30801]

I made a custom object with call method and pass it like:

role_number = NextNumber()

class Role(Model):
    id = fields.IntField(pk=True)
    number = fields.IntField(default=role_number)

When I called "aerich migrate" it gives following error:
AttributeError: 'NextNumber' object has no attribute 'name'

When I impelemnt name attribute for the object, it generates following SQL code in file in /migrate folder (among other lines)
ALTER TABLE role MODIFY COLUMN number INT NOT NULL COMMENT 'Priority (ordering) of the role' DEFAULT '<function cogs.db_utils.NextNumber:<class 'cogs.roles.Role'>:number>';
Obviously this leads to faililure of executing aerich upgrade command
