Hi Erik,
the idea was, that one Author can write in more than one language (eg. en and de), or no one at all. This was the background to use the ManyToManyField.
But the "error" Message must have an other reason?
Best Regards,
Mike

It looks like the Interest model is supposed to connect one author with one language. In that case, the fields the Interest class should be models.ForeignKey, not models.ManyToManyField.
