Django TypeError von Ajax Aktion

Question

Ich verwende DjangoTables, um Datensätze anzuzeigen. Ich möchte Ajax für einen Delete-Link verwenden, um den relevanten Site-Datensatz (und die mit ihm verknüpften Deal-Datensätze) zu löschen, ohne die Tabellenseite aktualisieren zu müssen.

Ein Klick auf ‚Löschen‘ löscht die relevanten Datensätze und verschwindet diese Zeile der Tabelle, wie ich wollte, aber dann bekomme ich dies in meiner Konsole:

TypeError: int() argument must be a string, a bytes-like object or a number, not 'builtin_function_or_method' 
[19/Nov/2016 03:51:56] "GET /sites/tested/sites/delete/?recordid=1 HTTP/1.1" 500 18116 

Das sieht nicht gut aus. Warum ist es dort und wie kann ich es weggehen lassen?

statische JS-Datei:

$(document).ready(function() { 
    $(".row-delete").click(function(event) { 
     event.preventDefault(); 
     var recordid; 
     recordid = $(this).attr("data-recordid"); 
     $.get('sites/delete/', {recordid: recordid}, function(data){ 
     }); 
     $(this).parent().parent().fadeOut("fast"); 
    }); 
}); 

Ausblick:

class SiteDelete(View): 
    model=Site 
    def get (self, request): 
     site_id = None 
     if request.method == 'GET': 
      site_id = request.GET['recordid'] 
      DealsToDelete = Deal.objects.filter(Site=id) 
      DealsToDelete.delete()  
      DeleteSite = Site.objects.get(id=site_id) 
      DeleteSite.delete() 

Tabelle

class TestedTable(tables.Table): 
    Approve = tables.TemplateColumn('<a href="{% url \"sites:approve\" id=record.id %}"</a>Approve') 
    Delete = tables.TemplateColumn('<a href="{% url \"sites:delete\" %}\" data-recordid = \"{{ record.id }}\" class=\"row-delete\">Delete</a>') 
    Name = tables.TemplateColumn('<a href="{% url \"deals:bysite\" record.id %}"</a>{{ record.Name }}') 

urls.py

from django.conf.urls import url 
from sites.views import SiteCreate, SiteUpdate, SiteDelete, IndexView, TestedView, DetailView, ApproveSite 
from django.core.urlresolvers import reverse_lazy 
app_name = 'sites' 
urlpatterns = [ 
    url(r'^$', IndexView.as_view(), name='site-list'), 
    url(r'add/$', SiteCreate.as_view(), name='site-add'), 
    url(r'(?P<pk>[0-9]+)/update/$', SiteUpdate.as_view(), name='site-update'), 
    url(r'delete/$', SiteDelete.as_view(), name='delete'),  
    url(r'tested/$', TestedView.as_view(), name='site-tested'), 
    url(r'(?P<pk>[0-9]+)/$', DetailView.as_view(), name='detail'), 
    url(r'(?P<id>[0-9]+)/approve/$', ApproveSite.as_view(), name='approve')

Answer 1

DealsToDelete = Deal.objects.filter(Site=id) 

In der obigen Zeile, die coe id verwendet, die nicht durch den Code definiert ist; so verwendet es die eingebaute Funktion id.

>>> id 
<built-in function id> 

sollten Sie ersetzen die id mit site_id Sie definiert.

DealsToDelete = Deal.objects.filter(Site=site_id)
