Dynamic choice option for select filed in Multivaluefield

[saranya k]

I want to set choices for ChoiceField in MultiValueField in form init. But its not getting updated.
class TestField(forms.MultiValueField):

    def __init__(self,*args, **kwargs):

        error_messages = {

        'incomplete': 'incomplete',

    }

        a = forms.ChoiceField(choices=((1,'a'),),required=True)

        b =forms.ChoiceField(choices=((2,'b'),),required=True)

        c = forms.ChoiceField(choices=((3,'c'),),required=True )   

        fields = (a,b,c )

        widget = TestWidget(mywidgets=[fields[0].widget, fields[1].widget, fields[2].widget])

        super(TestField, self).__init__(

            error_messages=error_messages, fields=fields,widget=widget,

        require_all_fields=True, *args, **kwargs

    )

    def compress(self, data_list):

        if data_list:  

            return {'academic':data_list[0],'ugs':data_list[1],'stu_sec':data_list[2]}    

class TestWidget(widgets.MultiWidget):

    def __init__(self, mywidgets,attrs=None):

        _widgets = (

        widgets.Select(attrs=attrs, choices=mywidgets[0].choices),

        widgets.Select(attrs=attrs,choices=mywidgets[1].choices),

        widgets.Select(attrs=attrs,choices=mywidgets[2].choices),

    )

        super(TestWidget, self).__init__(_widgets, attrs)

    def decompress(self, value):

        if value:

            return [value['academic'], value['ugs'], value['stu_sec']]

        return [None, None, None]  

 

 

class TestForm(forms.Form):

      t=TestField()

   def __init__(self, *args, **kwargs):

       super(TestForm, self).__init__(*args, **kwargs)

       self.fields['t'].fields[1].choices = ((1,1),)

 

Help me to achieve this…

Hi Saranya,

Please try in TestForm

> self.fields['t'].fields[1].widget.choices = ((1,1),)

Hope it helps
