Redirect to View based on value in Form (Django)

I'm getting value from user in form like this

#views.py

class DbTotsugoForm(LoginRequiredMixin, FormView):
    form_class = DbTotsugoForm
    template_name = 'totsugo_app/db_totsugo_chose.html'
    # success_url = reverse_lazy('<app-name>:contact-us')

    def form_valid(self, form):
        file_type = form.cleaned_data['file_type'] # here I have a value from user (book, folder)
        return super(DbTotsugoForm, self).form_valid(form)

and I would like to redirect user to list view - a data from DB based on the value above like this


class MYLook(ListView):
    template_name = 'totsugo_app/db_totsugo_list.html'
    # So based on `file_type` variable above I want to change `Book` to `Folder` here
    queryset = Book.objects.all()

How could I pass there that value, without creating MYLook two times for both values?

There are two ways you can do that. First, use URL Querystring to send the value from one view to another:

# in DbTotsugoForm view
def form_valid(self, form):
    file_type = form.cleaned_data['file_type'] # here I have a value from user (book, folder)
    return redirect("{}?fileType={}".format(reverse('<app-name>:contact-us'), file_type))

# in MYLook view

class MYLook(ListView):
    # ...

    def get_queryset(self, *args, **kwargs):
       file_type = self.request.GET.get('fileType', None)
       if file_type == 'Book':
          return Book.objects.all()
       return Folder.objects.all()

(Alternative Solution) you can use request.session to store the data. For example:

# in DbTotsugoForm view
def form_valid(self, form):
    file_type = form.cleaned_data['file_type'] # here I have a value from user (book, folder)
    self.request.session['file_type'] = file_type
    return super(DbTotsugoForm, self).form_valid(form)

# in MYLook view

class MYLook(ListView):
    # ...

    def get_queryset(self, *args, **kwargs):
       file_type = self.request.session.pop('file_type', None)
       if file_type == 'Book':
          return Book.objects.all()
       return Folder.objects.all()

FYI, you are using same name DbTotsugoForm for the form and view, you should change the name of the view to something else, ie DbTotsugoView.
