i have views. 1 triggers overview of guest's orders. , 1 sets order paid , should go overview:

@login_required def guest_detail(request, pk):     guest = get_object_or_404(guest, pk=pk)     open_orders = order.objects.filter(guest = guest, is_paid=false)     paid_orders = order.objects.filter(guest = guest, is_paid=true)     if request.method == "post":         form = registerguestform(request.post, instance=guest)         if form.is_valid():             guest = form.save(commit=false)             guest.save()             #post.published_date = timezone.now()             return redirect('guest_detail', pk=guest.pk)     else:             form = registerguestform(instance=guest)     context = {'form': form}     context['open_orders'] = open_orders     context['paid_orders'] = paid_orders     return render(request, 'hotel/guest_detail.html', context) 

this view rendered template:

<div class="col-md-8 col-xs-12">   <h3>guest information:</h3>   <form method="post" class="post-form">{% csrf_token %}     {{ form.as_p }}     <button type="submit" class="save-guest btn btn-default">save</button>   </form>   <h3>open orders:</h3>   <table class="table table-condensed table-guest-order">     <tr>       <th>date</th>       <th>amount</th>       <th>item</th>       <th>price</th>       <th><th>     </tr>    {% order in open_orders %}    <tr>       <td>{{ order.date }}</td>       <td>{{ order.amount }}</td>       <td>{{ order.item }}</td>       <td>{{ order.price }}</td>       <td><a href="{% url 'pay_order' pk=order.pk order_guest=order.guest.pk %}">pay</a></td>    </tr>    {% endfor %}  </table> </div> 

the pay_order link calls following view, should redirect me back, come from:

@login_required def pay_order(request, *args, **kwargs):     order = order.objects.get(pk=kwargs['pk'])     if order.is_paid false:         order.is_paid = true         order.paid_date = timezone.now()         order.save()     return redirect(views.guest_detail, pk=kwargs['order_guest']) 

but receive error

reverse 'pay_order' arguments '()' , keyword arguments '{'order_guest': 10, 'pk': 19}' not found. 1 pattern(s) tried: ['order/pay/(?p\d+)/$']

this urls.py used:

from django.conf.urls import url . import views  urlpatterns = [     url(r'^$', views.home, name='home'),     url(r'^rooms/$', views.listroomsview.as_view(), name='rooms'),     url(r'^service/$', views.service, name='service'),     url(r'^contact/$', views.contact, name='contact'),     url(r'^about/$', views.about, name='about'),     url(r'^guests/$', views.listguestsview.as_view(), name='guests'),     url(r'^guests/edit/(?p<pk>\d+)/$', views.guest_detail, name='guest_detail'),     url(r'^register_guest/$', views.register_guest, name='register_guest'),     url(r'^order/edit/(?p<pk>\d+)/$', views.order_detail, name='order'),     url(r'^order/$', views.register_order, name='new_order'),     url(r'^order/list/$', views.listordersview.as_view(), name='open_orders'),     url(r'^order/pay/(?p<pk>\d+)/$', views.pay_order, name='pay_order'),      ] 

when call guest_detail view guest has open payments. if guest has no open payments works fine. presume problem way try pass pk of guest pay_order view.

you're trying pass parameter "order_guest" pay_order view, url not expecting parameter, , neither view using it. shouldn't pass @ all; take out of values in {% url %} tag.

<a href="{% url 'pay_order' pk=order.pk %}">pay</a>
