Question

In Django, the canonical way of processing forms is:

if request.method == 'POST':
    form = SomeForm(request.POST)
    if form.is_valid():
        use the form data

I want to execute the same code whether there was no POST or the form was invalid – it’s a few lines of code, so I’m wondering if there is a nicer way of doing this than having two duplicate else blocks (one for the inner if and one for the outer)?

Answer 1

A very concise way that does not require a separate function, and doesn’t repeat conditions:

form = SomeForm(request.POST) if request.method == 'POST' else None

if form and form.is_valid():
    # do your valid-submission stuff
else:
    # do your invalid-submission stuff
