查看函數未在Django中調用

Question

這是view.py. show_checkout被調用並一直運行以return HttpResponseRedirect('/receipt/') ，但是由於某些原因， receipt視圖沒有被觸發。 沒有一個打印語句工作：

from django.shortcuts import render_to_response
from django.template import RequestContext
from django.core import urlresolvers
from django.http import HttpResponseRedirect

from ecomstore.checkout.forms import CheckoutForm
from ecomstore.checkout.models import Order, OrderItem
from ecomstore.checkout import checkout
from ecomstore.cart import cart
from django.core.context_processors import csrf

# Create your views here.
def show_checkout(request, template_name='checkout/checkout.html'):
    c = {}
    c.update(csrf(request))
    if cart.is_empty(request):
        cart_url = urlresolvers.reverse('show_cart')
        return HttpResponseRedirect(cart_url)
    if request.method == 'POST':
        postdata = request.POST.copy()
        form = CheckoutForm(postdata)
        if form.is_valid():
            response = checkout.process(request)
            order_number = response.get('order_number',0)
            print 'this is the order number: ' + str(order_number)
            error_message = response.get('message','')
            if order_number:
                request.session['order_number'] = order_number
#                receipt_url = urlresolvers.reverse('checkout_receipt')
                print request.session['order_number']
                return HttpResponseRedirect('/receipt/')

        else:
            error_message = 'Correct the errors below'
    else:
        form = CheckoutForm()
    page_title = 'Checkout'
    return render_to_response(template_name, locals(), context_instance= RequestContext(request))

##Currently this doesn't seem to be running
def receipt(request, template_name='checkout/receipt.html'):
    order_number = request.session.get('order_number','')
    print 'this is receipt order number: ' + str(order_number)
    if order_number:
        print 'in order_number'
        order = Order.objects.filter(id=order_number)[0]
        order_items = OrderItem.objects.filter(order=order)
        del request.session['order_number']
    else:
        print 'not in order number'
        cart_url = urlresolvers.reverse('show_cart')
        return HttpResponseRedirect(cart_url) 
    return render_to_response(template_name, locals(), context_instance=RequestContext(request))

這是checkout.urls：

from django.conf.urls.defaults import *
from ecomstore import settings

urlpatterns = patterns('ecomstore.checkout.views',
                       (r'^$','show_checkout',{'template_name':'checkout/checkout.html','SSL':settings.ENABLE_SSL},'checkout'),
                       (r'^receipt/$','receipt',{'template_name':'checkout/receipt.html','SSL':settings.ENABLE_SSL},'checkout_receipt'),
)

和urls.py：

urlpatterns = patterns('',

                       # Examples:
    # url(r'^$', 'ecomstore.views.home', name='home'),
    # url(r'^ecomstore/', include('ecomstore.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
                       url(r'^admin/', include(admin.site.urls)),
                       (r'^', include('catalog.urls')),
                       (r'^cart/$', include('cart.urls')),
                       (r'^checkout/$', include('checkout.urls')),
                       (r'^receipt/$', include('checkout.urls')),

)

重要提示：它目前也被轉發到localhost/cart

Answer 1

在你的主urls.py中，不要在正則表達式中使用“$”。 這似乎已經為我解決了。

Answer 2

我的猜測是您的意思是/ receipt / receipt
