Description
On line 899 of django/forms/models.py, the __len__ method returns the length of self.queryset, which always return as one -- instead, shouldn't it return the length of self.queryset.all()?
I have tried to get {% my_fk_field.choices|length %} and it kept returning as 1 -- only when I put {% my_fk_field.choices.queryset.all|length %} I got the correct length. I might be mistaken, but this looks like a bug to me...

I cannot reproduce the error, we will need some more code to see what's wrong here. Generally, calling len() on a queryset is a totally valid method to get the result length.
