As the generic relation lacks of some explaination : - do we necessary import "content type" contrib ? - do we necessary need to add in first object : content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = models.GenericForeignKey() - What would be the difference between : class TaggedItem(models.Model): """A tag on an item.""" tag = models.SlugField() content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = models.GenericForeignKey() class Animal(models.Model): common_name = models.CharField(maxlength=150) latin_name = models.CharField(maxlength=150) tags = models.GenericRelation(TaggedItem) and : class TaggedItem(models.Model): """A tag on an item.""" tag = models.SlugField() class Animal(models.Model): common_name = models.CharField(maxlength=150) latin_name = models.CharField(maxlength=150) tags = models.ManyToManyField(TaggedItem) ??
