Before 1.9, I had on my list of things to look at the fact that a standard
ModelChoiceField with a RadioSelect takes two queries. Now looking at this
in 1.10, the number of queries has ballooned (to 11 queries in my simple
test case).
I've not got far in looking for a solution, but this test passes in 1.9
and fails in 1.10 and master with `AssertionError: 11 != 2 : 11 queries
executed, 2 expected`:
{{{#!python
def test_radioselect_num_queries(self):
class CategoriesForm(forms.Form):
categories = forms.ModelChoiceField(
queryset=Category.objects.all(),
widget=forms.RadioSelect
)
template = Template('{% for w in form.categories %}{{ w }}{%
endfor %}')
with self.assertNumQueries(2):
template.render(Context({'form': CategoriesForm()}))
}}}
