Post Request not available inside get_queryset function inside ListView

问题

In ListView, I can easily use def post(self, request) method to make a post request from a list view. But I want to make the post request from def get_queryset(self) which I am not yet able to do. When I try to do it it shows "method 405 not allowed!" even though post method is allowed through http_method_names.

How can I access POST request inside get_queryset function?

class ZonListView(SearchMixin, SingleTableMixin, ListView):
    template_name = 'cadmin/list.html'
    model = Zon
    table_class = ZonTable
    search_fields = {
        'title': 'icontains',
        'description': 'icontains',
    }

def post(self, request):  # ***** this one works! ******
    try:
        toggle_status = request.POST.get('toggle-status')
        pk = int(request.POST.get('pk'))
        ....
    return HttpResponseRedirect(reverse('cadmin:zon_list'))

def get_queryset(self):
    qs = super(ZonListView, self).get_queryset()

    if self.request.POST:   #*****  Not working. 405 Error *****#
        try:
            toggle_status = self.request.POST.get('toggle-status')
            pk = int(self.request.POST.get('pk'))
            ......

    if self.request.GET:
        try:
            status = self.request.GET.get('status')
            qs = qs.filter(status=status)
        except Exception:
            pass

    return qs.distinct()

def get_context_data(self, **kwargs):
    ....

To make method allowed you need to implement function named same as method, post in your case. So to use request.POST in get queryset you also need to define post() method like this:

def post(self, request):  # ***** this method required! ******
    self.object_list = self.get_queryset() 
    return HttpResponseRedirect(reverse('cadmin:zon_list'))

def get_queryset(self):
    qs = super(ZonListView, self).get_queryset()

    if self.request.POST:   #*****  Now allowed *****#
        try:
            toggle_status = self.request.POST.get('toggle-status')
            pk = int(self.request.POST.get('pk'))
......

Look Django's View source to check how allowed methods defined.
