ModelMultipleChoiceField with MultiWidget ?

Hi, 

I've been struggling with this for the past two weeks, and i think it's time to ask.

I have and admin form that has a ModelMultipleChoiceField that is used to display

a ManyToMany model field that specifies a through model

class Person(models.Model):

    name = models.CharField(max_length=10)

    attributes = models.ManyToManyField('Attribute',through='Has',

                                        blank=True, null=True)

class Has(models.Model):

    person = models.ForeignKey('Person')

    attribute = models.ForeignKey('Attribute')

    value = models.CharField(max_length=10)

    

class Attribute(models.Model):

    name = models.CharField(max_length=10)

    atype = models.CharField(max_length=2, 

                                          choices=(('TF','true/false'),

                                                       ('IN','text')))

class PersonAdminForm(forms.ModelForm):

    class Meta:

        model = Person

    

    attrs = forms.ModelMultipleChoiceField( \

                    label='Attributes',

                    queryset=Attribute.objects.all(),

                    widget=forms.CheckboxSelectMultiple(),

                    )

This CheckboxSelectMultiple works fine, but I want to be able to render

each relation according to the Attribute.atype value, meaning if it is TF,

then tender it as a CheckBox, if it is IN the render it as an InputText

I inherited from CheckboxSelectMultiple so it does that, but then when I'm

on the admin form and for one specific attribute of type IN, rendered as a

TextInput,  I set a value (let's say 500) and then press save , the method

SelectMultiple.value_from_datadict gets called and passed as data :

<QueryDict: {u'csrfmiddlewaretoken': [u'GWLnuoTSTjjLmpYOizodBA4VA1FmwdQw'], 

u'_continue': [u'Save and continue editing'], u'name': [u'nico'], u'attrs': [ u'2']}>

And this is what has been driving me nuts! 

u'attrs': [ u'2'], 

As you can see it only passes the id of the attribute, not the id and the value. What I

need is something like 

u'attrs': [ (u'2','500')], 

Any ideas on how to fix this ?

Thanks!
