ModelForm vs CheckboxSelectMultiple

[Vance Dubberly]

So with a form that does this:
forms.ModelChoiceField(TransportMethod.objects.all(),
widget=forms.CheckboxSelectMultiple())

The first check box has no value and is labeled '---------' is there
an option to have that not exist. I don't don't see a passable param
which would turn it off in either ModelChoiceField or
CheckboxSelectMultiple. Am I blind?

You have to set a default.

... use the 'initial' attribute of the form field.

Unfortunately no luck

locations = forms.ModelChoiceField(Location.objects.all(),
widget=forms.CheckboxSelectMultiple(), initial='')
locations = forms.ModelChoiceField(Location.objects.all(),
widget=forms.CheckboxSelectMultiple(), initial=None)

no impact.

End result is I duplicated the code form the CheckboxSelectMultiple
and made my own. Only difference is that I test for for an option
value and don't append to the form if there isn't one

if option_value:
...
output.append(u'<li><label%s>%s %s</label></li>' % (label_for,
rendered_cb, option_label))

When creating your widget, you need to set empty_label = None, this
will supress the '----' choice.

Also, I think you want to use forms.ModelMultipleChoiceField in
conjunction with the widget forms.CheckboxSelectMultiple.

Martin,
Thank you, that let me delete my extra bunch of code and made me
feel silly for even going there. ;)
