I wanted a Django model with 2 foreign keys from the same table. It’s an event table which has 2 columns for employees: the ‘actor’ and the ‘receiver’. But I get this error:

Error: One or more models did not validate: tasks.task: Intermediary model TaskEvent has more than one foreign key to Employee, which is ambiguous and is not permitted.

Is there a better way to model this?

I think I’m going to add a TaskEvent_to_Employee table. There will be two records in it, one for each of the two employees related to each TaskEvent. Does anyone know an easier workaround?

  1. I haven’t done this yet, but I used inspectdb to generate the models.py file from an existing DB that does exactly that – this is what inspectdb threw back, so it should work:

    creator = models.ForeignKey(Users, null=True, related_name='creator') assignee = models.ForeignKey(Users, null=True, related_name='assignee')

    Hope that works for you – if it doesn’t I am going to have a problem too.
