using ForeignKeyRawIdWidget

[pablo platt]

Hi,

I want to extend ForeignKeyRawIdWidget so I want to be able to use it
without setting raw_id_fields.

With the following I don't get an error but I see no effect:

# models.py
class Product(models.Model):
    ...

class GroupProduct(Product):
    ...
    products = models.ManyToManyField(Product,
related_name="%(class)s_related")

# forms.py
class GroupProductAdminForm(forms.ModelForm):
    class Meta:
        model = GroupProduct
        widgets = {
            'products':
ForeignKeyRawIdWidget(GroupProduct._meta.get_field('products').rel),
        }

This gives me an error: *init*() takes at least 2 non-keyword arguments (1
given)
class GroupProductAdminForm(forms.ModelForm):
    class Meta:
        model = GroupProduct
    products =
forms.ModelMultipleChoiceField(widget=ForeignKeyRawIdWidget(GroupProduct._meta.get_field('products').rel))

What am I doing wrong?

Thanks
