Django Forms - How to Use Prefix Parameter

Question

Say I have a form like:

class GeneralForm(forms.Form):
    field1 = forms.IntegerField(required=False)
    field2 = forms. IntegerField(required=False)
         


        

Answer 1

You process each form as you normally would, ensuring that you create instances which have the same prefixes as those used to generate the form initially.

Here's a slightly awkward example using the form you've given, as I don't know what the exact use case is:

def some_view(request):
    if request.method == 'POST':
        form1 = GeneralForm(request.POST, prefix='form1')
        form2 = GeneralForm(request.POST, prefix='form2')
        if all([form1.is_valid(), form2.is_valid()]):
            pass # Do stuff with the forms
    else:
        form1 = GeneralForm(prefix='form1')
        form2 = GeneralForm(prefix='form2')
    return render_to_response('some_template.html', {
        'form1': form1,
        'form2': form2,
    })

Here's some real-world sample code which demonstrates processing forms using the prefix:
