Well, are you talking about a forms.Form or a forms.ModelForm? A ModelForm will require any fields that are required in the model. A Form's fields default to being required, unless you specify otherwise. Any fields not filled will return a message to the user. It sounds like you want a way to know whether all the fields are blank, but if the field is invalid, what does that matter? It can't be processed if one required field is left blank or if all of them are. What is your use-case for wanting to know exactly how much of the form is blank?
