Django error message “Add a related_name argument to the definition”

Question

D:\\zjm_code\\basic_project>python manage.py syncdb
Error: One or more models did not validate:
topics.topic: Accessor for field \'content_type\' clashes with rel         


        

Answer 1

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:

content_type = ForeignKey(Topic, related_name='topic_content_type')

See here for more. http://docs.djangoproject.com/en/dev/ref/models/fields/#django.db.models.ForeignKey.related_name
