How to return a query set in get_queryset() in Django

Question

I'm currently trying to convert my FBV codes to CBV. get_context_data is working well by returning contexts that I put in. However, get_queryset() returns NOTHING for some reason. To double-check, I tried to print search_stores right before returning it and it printed the queryset that is supposed to be printed. However, when I printed it on Django template, by typing {{ search_stores }}, it shows nothing. Am I using get_queryset in a wrong way?

class SearchListView(ListView):
    model = Store
    template_name = 'boutique/search.html'
    # paginate_by = 5

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['search_text'] = self.request.GET.get('search_text')
        context['sorter'] = self.request.GET.get('sorter')
        if not context['sorter']:
            context['sorter'] = 'popularity'
        return context

    def get_queryset(self):

        search_text = self.request.GET.get('search_text')
        sorter = self.request.GET.get('sorter')

        if search_text:
            search_stores = Store.objects.filter(Q(businessName__icontains=search_text) | Q(mKey__icontains=search_text))
            if sorter == 'businessName':
                search_stores = search_stores.order_by(sorter)
            else:
                search_stores = search_stores.order_by(sorter).reverse()
        else:
            search_stores = ''

        for store in search_stores:
            store.mKey = store.mKey.split(' ')

        print(search_stores)
        return search_stores

Your queryset is accessible via the context_object_name. By default it's object_list if you don't provide context_object_name
You can access the queryset in templates with object_list

If you want to change the name, change the context_object_name:

class SearchListView(ListView):
   model = Store
   template_name = 'boutique/search.html'
   context_object_name = 'search_stores'

search_stores will be the variable accessible to loop through in templates

I just have a minor question. Is it possible to return multiple query sets in get_queryset()?

Lemayzeur Over a year ago

get_queryset is only for the Model belongs to the CBV, if you want to send multiple queryset, you can do so in get_context_data()

ok then if I wanna use pagination on a specific queryset, that queryset must be returned from get_queryset. Is that correct?
