10366	model for MultipleChoiceField	tangc	nobody	"Ref: db/models/fields/__init__.py

class Field(object) has init with {{{choices=None}}}. It would be good to have a {{{multi_choices=None}}}

def formfield has code {{{ form_class = forms.TypedChoiceField }}}. So It would be like the follows:

{{{
            if self.multi_choices:
                form_class = forms.MultipleChoiceField
            else:
                form_class = forms.TypedChoiceField
}}}

The minimum code change can deal with model to form with MultipleChoiceField. It worked nicely.
