Error when Making Migration

Hello All,

When I finished with all models creation, and want to make the migrations, I faced this error:

> tags.TaggedItem.content_type: (contenttypes.E003) ‘TaggedItem.content_type’ is not a ForeignKey.
> HINT: GenericForeignKeys must use a ForeignKey to ‘contenttypes.ContentType’ as the ‘content_type’ field.

I imported all modules needed just as Mosh did in the videos.

solved …thank you you all
