How to handle form fields?

Question

Django

I have 3 optional fields based on which the database is searched and the result is returned.
I'm trying to figure out how best to make a view if you need to check many fields. Write if request.GET.get('', '') for each input, or is there another, more "jung" way? And if you filled in all the fields at the same time, or two out of three?
Also a question about organizing urls. Now I did this: url(r'^results/', views.search_results, name='search_results'), where query_string with parameters is substituted. What if I want to make beautiful URLs, while the condition remains, the request parameters can be different - how is this done? For example,

Perhaps you should pay attention to the following, in CBV you can write two post and get methods:

class MyFormView(View):
    form_class = MyForm
    initial = {'key': 'value'}
    template_name = 'form_template.html'

    def get(self, request, *args, **kwargs):
        form = self.form_class(initial=self.initial)
        return render(request, self.template_name, {'form': form})

    def post(self, request, *args, **kwargs):
        form = self.form_class(request.POST)
        if form.is_valid():
            # <process form cleaned data>
            return HttpResponseRedirect('/success/')

But you can not implement the post method, but only implement the get method, and in it process the HttpRequest.GET property of the request object: https://docs.djangoproject.com/en/1.10/ref/request...
