{{{
from django.forms import ModelForm

class TrustForm(ModelForm):

    class Meta:
        pass # forgotten model attribute here
}}}


If Meta in formclass has no model attribute it raises exception like this:

TypeError at /exampleurl/ 'NoneType' object is not callable.

I guess my patch makes more informative exception messages. ValueError and TypeError may be wrong here, may be use AssertError instead, don't know. "		closed	Forms	dev		fixed			Design decision needed	1	0	0	0	0	0
