This way, you don't have to worry about it and you get the right value
every time instead of getting an error every now and then.

Yes, and everything looks to be installed correctly under site-

probably get an import error.

Worked like a charm. It was the ModelChoice field. It was trigging the

Hi,
I have the same, so I've decided to live with the following
workaround.
Form.clean() is not reported properly for inlines but
Form.clean_() works fine.
In theory only Form.clean() is recommended for cross field validation
but in fact Form.clean_() can also refer to the other
fields.

Looking at the source, ModelChoiceField validates the given id against
the initial queryset, where you provided an empty one.
"models.Gallery.objects.none()"
So no id's validate. I think changing none() to all() should make it
work.

Frank,
your snippet works great. I just removed the int conversion on
bf_data, since I want to have f.is_valid() = false if the user submits
something different than an integer.
Without you I would never be able to solve the problem.

I would swear that I posted a response to this earlier today, but it
doesn't seem to show up in the group. The problem you're having is
because of the 'cart_item_' that you are adding in. It is not being
added into the dictionary that is assigned to the form's data.

If you look at f.errors or k.errors, you'll see:
{'cart_item_b': [u'This field is required.'], 'cart_item_a': [u'This
field is required.']}
The reason for this is that the forms data looks like:

or

Frank,
thak you for your help.
I worked on the form model using bound field, and now the forms is
bound.
class CartForm(forms.Form):
def __init__(self, a):
super(CartForm, self).__init__(a)
for key in a.keys():
self.fields['cart_ite
In your example,
self.fields[str(key)]=forms.CharField(initial=c[key])
isn't doing what you expect.
You are setting the initial attribute of a field, not creating
a BoundField. See django/newforms/forms.py, and look at the
comments for BaseForm and Form and the code for
BoundField.

Thanks Richard that seems like a much more logical way of doing it.
Works with one slight change:
form_data = request.POST.copy()
form_data['domain_id'] = domain_id
form = DNSRecordForm(form_data)

Off the top of my head, how about something like this:
form_data = request.POST
form_data['domain_id'] = domain_id
form = DNSRecordForm(form_data)
if form.is_valid():
form.save()
I think you should get the idea. Obviously the DNSRecordForm will
have to have the domain field in it.

Even if you supply a valid inital value? It does not sound well for me...
No, invalid data should not pass. But neither should an initial field
value raise an error when the POSTed data is exactly the same as the
starting value; it should just be ignored and the value discarded.
