Changes between Initial Version and Version 1 of Ticket #34168, comment 2

-              initial
+              v1
 The specific problem I am facing is that I need to access an existing database whose schema I cannot alter; I used the Django tool to extract the tables to create models.py, which worked great, and I already hacked the model definitions, e.g. to replace a simple IntegerField with a ForeignKey. But there are specific tables, where there is an IntegerField which may contain a ForeignKey from more than one table (think of a group and a user table; whether it is a user or a group, is defined by another column):
+{{{
 class Permission(models.Model):
     ...
     user_or_group_id = models.IntegerField(db_column='user_or_group_id', blank=True, null=True)
     is_group = models.IntegerField(db_column='is_group', blank=True, null=True)
+}}}
