python - Django syncdb error: One or more models did not validate

Question

/mysite/project4

 class notes(models.Model):
   created_by = models.ForeignKey(User)
   detail = models.ForeignKey(Details) 

Details and User are in the same module i.e,/mysite/project1 In project1 models i have defined

   class User():
      ......

   class Details():
      ......

When DB i synced there is an error saying

Error: One or more models did not validate: project4: Accessor for field 'detail' clashes with related field . Add a related_name argument to the definition for 'detail'.

How can this be solved..

thanks..

Gee we just had this one; and I answered...

You have a number of foreign keys which django is unable to generate unique names for.

You can help out by adding "related_name" arguments to the foreignkey field definitions in your models. Eg:

 class notes(models.Model):
    created_by = models.ForeignKey(User, related_name="note_created_by_user")
    detail = models.ForeignKey(Details, related_name="noted_and_detailed")
