Yes, but then you simply create multiple Interest objects, right? One for every author-language combination. Your field names are singular, not plural, which tells me you should use a ForeignKey field. The current Interest model links multiple Authors with multiple Languages, which doesn't make much sense. If you want to use ManyToManyField, then you put a "interests" field to Language directly on the Author model. > But the "error" Message must have an other reason? The direct cause is that you are trying to print self.author in the __str__ method. self.author is a ManyRelatedManager, so you should use self.authors.all() to access the individual authors. But you should change you models instead of fixing this error :-) Erik -- You received this message because you are subscribed to the Google Groups "Django users" group.
