Generic many-to-many relationships in django admin

Question

I have few similar models in Django:

class Material(models.Model):
    title = models.CharField(max_length=255)
    class Meta:
        abstract = True

class Ne

Shouldn't it work if you just turn Danny's example around and define the generic relation on the side of of the Topic-Model?

See the example in django's docs: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#using-generic-relations-as-an-inline

Adapted to this question:

class Topic(models.Model):
    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField()
    content_object = generic.GenericForeignKey("content_type", "object_id")

It probably makes sense to additionally define the reverse relationsship on each related model.

class News(models.Model):
    topics = generic.GenericRelation(Topic)

And now you could create a TopicInline and attach Topics to news, articles, whatever ...

class TopicInline(generic.GenericTabularInline):
    model = Topic

class ArticleAdmin(admin.ModelAdmin):
    inlines = [
        TopicInline,
    ]

class NewsAdmin(admin.ModelAdmin):
    inlines = [
        TopicInline,
    ]
