/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..
