あるビューから別のビューにリダイレクトする 4 つのビューがあり、これが実行中ですが、URL が機能していません。

def show_item(request,id):
        a = Item.objects.get(pk=id)
        form = PartialOrderItemForm(request.POST,instance=a)
        # check validation of posted data
        if form.is_valid():
            order.add_to_order(request,a)
            url =urlresolvers.reverse('order_index',kwargs={'id':a.id})
            # redirect to order page
            return HttpResponseRedirect(url)
        ......
    return render_to_response('item.html',context,context_instance=RequestContext(request))

上のビューは下のビューにリダイレクトされます。

def show_order(request,id):
    item = Item.objects.get(pk=order_id)
    if request.method == 'POST':
        postdata = request.POST.copy()
        if postdata['submit'] == 'Remove':
            order.remove_from_order(request)
        if postdata['submit'] == 'Update':
            order.update_order(request)
        if postdata['submit'] == 'checkout':
            return HttpResponseRedirect(urlresolvers.reverse('checkout',kwargs={'id':order_id}))

show_order以下にリダイレクトしshow_checkoutます

def show_checkout(request,id):
    ......
    if request.method == 'POST':
        resto = Restaurant.objects.get(pk=id)
        postdata = request.POST.copy()
        form = forms.CheckoutForm(request.POST,postdata)
        if form.is_valid():
            order_created = create_order(request,resto)
            ....
            if postdata['submit'] == 'place order':
                reciept_url = urlresolvers.reverse('checkout_reciept')
                return HttpResponseRedirect(reciept_url)
    return render(request,'checkout/checkout.html',context)

urls.py、

url(r'^your_order/(\d+)/$',show_order,name="order_index"),
    url(r'^item/(?P<id>\d+)/$',show_item, name="item_order"),
    url(r'^checkout/(?P<id>\d+)/$',show_checkout,name="checkout"),

これはすべて、エラーを与える最初のリダイレクトで壊れますNoReverseMatch。私はそれを正しく行っていません。シナリオを検索するための URL を作成する方法についての簡単な説明は非常に受け入れられています。

キャサリンが提案するように問題を修正すると、DoesNotEXist で例外が発生しますShow_checkout

問題全体がどのように解決されるか..キャサリンのおかげで、 show_order注文IDではなくアイテムIDが必要でした。

def show_order(request,id):
    item = Item.objects.get(pk=id)

そうではなく、

def show_order(request,id):
    item = Item.objects.get(pk=order_id)

また、show_checkout では、別の方法でレストラン ID を取得する必要がありました

これではない

def show_checkout(request,id):
    ......
    if request.method == 'POST':
        resto = Restaurant.objects.get(pk=id)

でもこれは

def show_checkout(request,id):
    .......
    if request.method == 'POST':
        item = Item.objects.get(pk=id)
        postdata = request.POST.copy()
        form = forms.CheckoutForm(request.POST,postdata)
        if form.is_valid():
            order_created = create_order(request,item)

そしてcreate_order

 def create_order(request,obj):
        """create new order containing each orderitem instance,save order and empty the order."""
        anon_user = User.objects.get(id=settings.ANONYMOUS_USER_ID)
        resto = Item.objects.get(pk=obj.id)
        orders = Order()

        checkout_form = forms.CheckoutForm(request.POST,instance=orders)
        checkout = checkout_form.save(commit=False)

        checkout.created_by = anon_user
        checkout.modified_by = anon_user
        checkout.restaurant = resto.owner

order_idの代わりに定義しますid。にはorder_id値がありません。

def show_order(request,id):
    item = Item.objects.get(pk=id)
    .......

url(r'^your_order/(?P<id>\d+)/$',show_order,name="order_index"),
url(r'^item/(?P<id>\d+)/$',show_item, name="item_order"),
url(r'^checkout/(?P<id>\d+)/$',show_checkout,name="checkout"),
