Tidier form validation

form_views.py

# example from Django docs https://docs.djangoproject.com/en/4.2/topics/forms/
def get_name(request):
    # if this is a POST request we need to process the form data
    if request.method == "POST":
        # create a form instance and populate it with data from the request:
        form = NameForm(request.POST)
        # check whether it's valid:
        if form.is_valid():
            # process the data in form.cleaned_data as required
            # ...
            # redirect to a new URL:
            return HttpResponseRedirect("/thanks/")

    # if a GET (or any other method) we'll create a blank form
    else:
        form = NameForm()

    return render(request, "name.html", {"form": form})

# a bit tidier

def get_name_improved(request):
    # initialize form: make sure to explicity pass in request.POST to invalidate
    # any missing params
    form = NameForm(request.POST) if request.method == "POST" else NameForm()
    
    # this will always be False if form is unbound (POST is None) so we can call it safely here
    if form.is_valid():
        return HttpResponseRedirect("/thanks/")
      
    return render(request, "name.html", {"form": form})
