Re: def altword_list(self, request, word_id):

Well, I tried to understand the code. Correct me if I did not understand it:

* you are calling AltwordlistView from r'^altword_list/(?P<pk>\d+)/$

* being a DetailedView on Altword, AltwordlistView extracts the Altword with the given pk with a query like Altword.objects.get(pk=pk)

* you set the context you send to the template, in the get_context_data

There, in get_context_data() you have to initialize all the keywords you are going to use in the template. In this case poll_list.

Note that you define a get_queryset() method in AltwordlistView, but I think it is not called in a DetailedView, only ListView uses it.

So I'd fix the whole thing this way:

* get rid of get_queryset()

* get rid of the altword_list() function view

* put something like context['poll_list'] = Altword.objects.filter(word__pk=word_id).order_by('-votes') in get_context_data()

If you are trying to show a list of objects, however, I suggest you to try and use a ListView, where you can define your queryset, as you tried to do with the get_queryset() method.

Try and let me know if something starts to work. Feel free to ask further if the matter is not clear.

Hi Leo,

get_query() function in class AltwordlistView which I refer to as Filter-5 didn't give me the ordered list result that I wanted.  So somebody on #django IRC helped me to fix that problem by giving me altword_list() function which I refer to as Filter-8.

You can basically ignore all the other Filter codes but I left it there in case it might help you see what I'm trying to do.

My main focus right now is to connect the Filter-8 code to my template altword_list.html but I don't know how to do it.

Can you check the code you posted? The get_query() function is empty so this code, as posted, can not run.

Please post even the urls you are using to call the view.

Hi,

I got some help by somebody on #django IRC.  They gave me this code snippet to fix my problem.  But I'm having problems incorporating that code into my Class file because Template file says "No list is available" when I try to access the list variable.  What am I doing wrong?

# Filter 8

    def altword_list(self, request, word_id):

        #object_list = AltWord.objects.filter(word__pk=word_id).order_by('-votes')

        object_list = Altword.objects.filter(word__pk=word_id).order_by('-votes')

        return render(request, 'navi_polls/altword_list.html', {

            'poll_list': object_list,

        })

Views

#_______________________________________________________________________________

class AltwordlistView(generic.DetailView):

    #model = Word

    model = Altword

    template_name = 'navi_polls/altword_list.html'

    context_object_name = 'poll'

    def get_queryset(self):

# Filter 5

        #return Word.objects.filter(direct_transl_word='')

    def get_context_data(self, **kwargs):

        context = super(AltwordlistView, self).get_context_data(**kwargs)

# Filter 4b

        filter_4b = Altword.objects.filter(rosword__direct_transl_word='').order_by('-votes')

# Filter 7

        filter_7 = Altword.objects.vote_order()

# Filter 8b

#        filter_8b = Altword.objects.filter(word__pk=word_id).order_by('-votes')

        context.update({

            "filter_4b": filter_4b,

            "filter_7": filter_7

 #           "filter_8b": filter_8b

        })

        return context

# Filter 8

    def altword_list(self, request, word_id):

        #object_list = AltWord.objects.filter(word__pk=word_id).order_by('-votes')

        object_list = Altword.objects.filter(word__pk=word_id).order_by('-votes')

        return render(request, 'navi_polls/altword_list.html', {

            'poll_list': object_list,

        })
