Hi, I've been struggling with dynamic forms and until now I'm loosing the
battle :S
The thing is that I have a HomeAdmin(ModelAdmin) that uses the form
HomeAdminForm(ModelForm)
The HomeAdminForm redefines the __init__ method to add a bunch a of hidden
input fields like this :
class HomeAdminForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(HomeAdminForm, self).__init__(*args, **kwargs)
#add all the attribute types
for at in HomeAttrType.objects.all():
self.fields['attr_type_%s' % at.name] = forms.CharField(
widget=forms.HiddenInput(attrs={'class': 'hidden'}),
label='', bound=True)
So, now I want the HomeAdmin to render all this stuff into the from, but
when I try to
add this fields into the fieldset attribute and load the page it fails
saying.
Unknown field(s) (attr_type_foo, attr_type_prueba, attr_type_carnasa)
specified for Home
Those fields are the ones I added at HomeAdminForm.__init__ this way
class HomeAdmin(admin.ModelAdmin):
form = HomeAdminForm
def __init__(self, *args, **kwargs):
super(HomeAdmin, self).__init__(*args, **kwargs)
hidden_fields = []
for at in HomeAttrType.objects.all():
hidden_fields.append('attr_type_%s' % at.name)
self.fieldsets.append((None, {'fields' : hidden_fields, }))
The problem seems to be that the constructor for HomeAdminForm gets called
after
the constructor for HomeAdmin, so all the added fields are not there yet
when
HomeAdmin.__init__ is called.
Is what I'm trying do ok ?, Is there any way to fix this ?
Thanks dudes,
