Django 与#x27相反；创建订单'；没有找到任何参数。尝试了1种模式：['；创建订单/（？P<；pk>；[^/]+；）/$&]

当我使用

path('create_order/<str:pk>/', views.createOrder, name="create_order"),

url.py

from django.urls import path
from . import views


urlpatterns = [
    path('', views.home, name="home"),
    path('products/', views.products, name='products'),
    path('customer/<str:pk_test>/', views.customer, name="customer"),

    path('create_order/<str:pk>/', views.createOrder, name="create_order"),
    path('update_order/<str:pk>/', views.updateOrder, name="update_order"),
    path('delete_order/<str:pk>/', views.deleteOrder, name="delete_order"),


]

def createOrder(request, pk):
    OrderFormSet = inlineformset_factory(Customer, Order , fields=('product','status'), extra=9)
    customer = Customer.objects.get(id=pk)
    formset = OrderFormSet(queryset=Order.objects.none(), instance=customer)
    #form = OrderForm(initial={'customer':customer})
    if request.method == 'POST':
        #print('printing post', request.POST)
        formset = OrderFormSet(request.POST, instance=customer)
        if formset.is_valid():
            formset.save()
            return redirect('/')

    context = {'formset': formset}
    #return redirect('accounts/order_form.html', context)
    return render(request, 'accounts/order_form.html', context)

class Customer(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    phone = models.CharField(max_length=200, null=True, blank=True)
    email = models.CharField(max_length=200, null=True, blank=True)
    date_created = models.DateTimeField(auto_now_add=True, null=True)

    def __str__(self):
        return self.name

from django.urls import path

    path('products/', views.products, name='products'),

    path('create_order/<str:pk>/', views.createOrder, name="create_order"),
    path('update_order/<str:pk>/', views.updateOrder, name="update_order"),
    path('delete_order/<str:pk>/', views.deleteOrder, name="delete_order"),

from django.forms import inlineformset_factory
def createOrder(request, pk):
    OrderFormSet = inlineformset_factory(Customer, Order, fields=('product', 'status'), extra=10 )
    customer = Customer.objects.get(id=pk)
    formset = OrderFormSet(queryset=Order.objects.none(),instance=customer)
    #form = OrderForm(initial={'customer':customer})
    if request.method == 'POST':
        #print('Printing POST:', request.POST)
        #form = OrderForm(request.POST)
        formset = OrderFormSet(request.POST, instance=customer)

            return redirect('/')

    context = {'form':formset}
    return render(request, 'accounts/order_form.html', context)

我也尝试过重定向，但不起作用。问题是URL.py

customer.html

同样，我不知道它为什么会显示此错误以及问题出在哪里，但只是使用GitHub的相同代码重新应用了它，它就工作了。如果有人知道它是如何工作的，那在不久的将来将非常有用。

我知道问题出在哪里

---

在dashboard.html中，您应该删除包含{%url'create_order'%}

的行。在dashboard中，您应该删除具有create order的行 因为使用了没有id的创建订单url，所以出现了一个错误

我最终得到了错误。 所以，错误就在这里 我们使用的href id{%url'create_order'customer.id%}

这在customer.html中，因此customer.id将获得views.customer提供的值 但是如果你从你的观点来看，顾客， 上下文={'customers'：customers，'orders'：orders，'orders\u count'：orders\u count} 因为我们看了一个教程视频，那个家伙做了一些我们没有做的改变，因为视频中没有显示

他所做的改变是 他将“customers”改为“customer”，现在customer.html的上下文很好

---

因为现在它知道什么是customer.id

这很有道理，因为如果它有一个参数，你需要指定

pk

参数的值，所以

{%url'create_order'pk=42%}
