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!
