you have a view like so:

def render_questions(request):
.
.  Some code here
.

   if request.method == 'POST':
        form_list = create_question_forms(request.POST)

        for form in form_list:
            if form.is_valid():
                form.save()

        return HttpResponseRedirect(some_url) #direct to url after
    else:
            form_list = create_question_forms()

    return render_to_response('your_template.html', {'forms': form_list})

the request.POST on submit contains a QueryDict object that contains all of your submitted data, so pass this to your create_question_forms object, which is defined like this:

def create_question_forms(data=None):
    question_list = ... # get all your questions from here via db or where ever your questions are stored
    form_list = []

   for pos, question in enumerate(question_list):
            #data is the request.POST and if it is there will populate you questions with the user choices
            form_list.append(QuestionMulipleChoiceRadio(question, data, prefix=pos))

    return form_list

Then your Question form would be something like this:

class QuestionCheckBox(forms.Form):
    answers = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, label="")
    def __init__(self, question, *args, **kwargs):
        super(QuestionCheckBox, self).__init__(*args, **kwargs)
        self.text = question.text
        self.question = question

        answers = question.answer_set.all().order_by('index')
        self.fields['answers'].choices = [(str(i), a.text) for i, a in enumerate(answers)]
        self.choices_dict = dict(self.fields['answers'].choices)
        self.count = count

    def save(self, commit=True):
      ...
      Some more code, do what you want
      ....

Confusing huh? Well as much detail as I can get into right now. But basically when the user submits the data with the post.Tehn you pass the post to the view; then pass that data to your form and it will rebuild it with the data from the request.POST; then once the form is valid and the save method is called. You can save it to where ever you like DB, XML and JSON file whatever it is up to you. Hope this helps!

If you want the records to be unique by the foreign keys then put a unique constraint on the table with those fields instead of making it the primary key. Then add the identity field as the primary. This should work. Kind of weird but that is what you have to do, to make your tables to play nicely with Entity framework.

/* …. */
D updateD = GetDByID(input, input, input);
// SUPPOSE: this is the Client Side
EntityReference b = new EntityReference();
b.EntityKey = b2.EntityKey;
updateD.BReference = b;

}

oldRef.EntityKey = newRef.EntityKey;

Looks like you are taking an old entity key and changing it to a new one. As you will notice in the UpDateStore method I create a “new” reference object not using an existing one. Assign the entity key to the new reference object, then assign the new reference object to the object I am updating.

You cannot take an existing entity key and update it to a new one. It is violating a constraint on your database table hence your entity model definition. So use a new object.

Please post more code to verify what exactly you are doing. TTYL

the exception is:
A referential integrity constraint violation occurred: A property that is a part of referential integrity constraint cannot be changed when the object has a non-temporary key.

I would love to see some example code on how to handle the submission in a view!

Cheers…
