A Better Django Admin ManyToMany Field Widget

rated 0 times [ 40] [ 2] / answers: 1 / hits: 40641 / 14 Years ago, tue, march 22, 2011, 12:00:00

I find the the Django Admin's default models.ManyToManyField widget to be cumbersome to use. It's the HTML select element and if you have a lot of Objects of the other model then it's quite impractical to actually find the other Objects you want to associate with this Object. And if you have a lot of objects of the other model it seems to even slows down the rendering of the Admin page.

I'm aware that I can build my own custom admin widget and apply it to my ManyToManyFields as I see fit, but are there any pre-built ones out there that I might use instead? In my dreams, I picture an auto-completing text input HTML widget. Is this even practical/possible to do in the Django admin framework?

Thanks.

Try using the filter_horizontal attribute on your admin class, for example:

class SomeModelAdmin(admin.ModelAdmin):

    filter_horizontal = ('users',)

As mentioned in the documentation, adding a ManyToManyField to this list will instead use a nifty unobtrusive JavaScript filter interface that allows searching within the options. filter_vertical does the same thing with a slightly different layout.
