python - Django 中未调用 View 函数

Question

这是 view.py。 show_checkout 被调用并一路运行以返回 HttpResponseRedirect('/receipt/')，但由于某种原因，receipt View 不可见被解雇。所有打印语句都不起作用:

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))

这是结账网址:

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:目前它也被转发到 localhost/cart

在主 urls.py 中，不要在正则表达式中使用“$”。这似乎已经为我解决了。
