自定義get_queryset函式

class Browse(generic.ListView):
    template_name = 'app/browse.html'
    paginate_by = 25

    # Modifying the get_context_data method

    def get_context_data(self, **kwargs):
        context = super(Browse, self).get_context_data(**kwargs)
        q = self.request.GET.get("browse"
 
)
        context['input'] = q
        return context

    def get_queryset(self):
        queryset = Cats.objects.all()
        if self.request.GET.get("browse"):
            selection = self.request.GET.get("browse")

自定義get和get_context_data函式

    def get(self, request, *args, **kwargs)
 
:
        #query_string = request.META.get('QUERY_STRING', '')
        self.user = request.user
        #if self.request.GET.get("Condition"):
        return super(thisview, self).get(request, *args, **kwargs)

    def get_context_data(self, **kwargs):
        context = super(thisview, self).get_context_data(**kwargs)
        context.update({
            'par': self.par,
        })
        return context
