Django - Overriding cleaned_data

I have a form with fields that are not on the correspondent model. I use these "virtual" fields to fill a real one with the clean() method.

So, the user enters with data in the "virtual" field and I have to fill the real field with this same data.

I thought that overriding the cleaned_data["real_field"] would be possible, but I cannot do it.

My code is something like this:

(...)
cleaned_data['real_field'] = cleaned_dat开发者_开发问答a['virtual_field']
(...)
return cleaned_data

Any ideas on another way I can do it, or if I am doing it wrong, how do I fix it?

In your form class:

def clean(self):
    cleaned_data = self.cleaned_data
    cleaned_data['real_field'] = cleaned_data['virtual_field']
    return cleaned_data

Nevermind, I had an error. The real field was not declared in the fieldsets (admin.py).
