How can I avoid form.is_valid() flagging an empty field as an error in Django?

I have a template that is used for updating a table. However, the user can choose to update one field or all of them. The chances are that he won't be updating all the fields, so I want to be able to run form.is_valid(), but I don't want to have it return false if there are empty fields in the form which there will almost certainly be.

I don't want to use required=False in the form, because there is another template that uses the same form where the user must fill in almost all the fields.

The simplest thing to do would probably be to subclass your form and set required=False in the subclass, either repeating the field definition or doing it in __init__. Otherwise, you could set required=False in your view, eg:

def some_view(request):
    if request.METHOD == 'POST':
        form = SomeFormClass(request.POST)
        form.fields['fieldname'].required = False
        if form.is_valid():
            # etc
