Comment:

 I think you need to look it `inlineformset_factory` and/or
 `BaseInlineFormSet`. As far as I can tell, `BaseModelFormSet` is working
 [https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#changing-
 the-queryset as documented].

 in your code although I don't see anything odd.

 Tim, I used pdb to render the html on the server side and it is having the
 data of all the fields in the model populated in the formset when it has
 to be rendered empty for a GET request. I tried it on a totally different
 codebase and app and I could see the same issue.
