Django duplicates URLS

Question

我是Django的新手。在处理我的项目时，当我想继续下一页时，它会生成一个重复的 URL。这是我的主页网址：http://127.0.0.1:8000/

如果我想查看特定客户的个人资料，我希望 URL 应该是这样的：http://127.0.0.1:8000/customer/1/

但我得到这个：http://127.0.0.1:8000/customer/customer/1/

如果有人能帮助我，我将不胜感激，我是一个菜鸟。

这是我 urls.py：

from . import views
urlpatterns = [
path('', views.home, name = 'home'),
path('products/', views.products, name = 'product'),
path('customer/<str:pk>/', 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'),
]

我的 views.py：

from django.http import HttpResponse
from django.forms import inlineformset_factory
from django.urls import reverse
from .models import *
from .forms import OrderForm

def home(request):
orders = Order.objects.all()
customers = Customer.objects.all()
total_customers = customers.count()
total_orders = orders.count()
delivered = orders.filter(status='Delivered').count()
pending = orders.filter(status='Pending').count()
context = {'orders':orders, 'customers':customers,
'total_orders':total_orders,'delivered':delivered,
'pending':pending}
return render(request, 'accounts/dashboard.html', context)
def products(request):
products = Product.objects.all()
return render(request, 'accounts/products.html', {'products':products})
def customer(request, pk):
customers = Customer.objects.all()
customer = Customer.objects.get(id=pk)
orders = customer.order_set.all()
orders_count = orders.count
context = {'customer':customer, 'orders':orders, 'orders_count': orders_count}
return render(request, 'accounts/customer.html', context) 
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)
if request.method == 'POST':
formset = OrderFormSet(request.POST, instance=customer)
if formset.is_valid():
formset.save()
return redirect('/')

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

def updateOrder(request, pk):
order = Order.objects.get(id=pk)
form = OrderForm(instance=order)

if request.method == 'POST':
form = OrderForm(request.POST, instance=order)
if form.is_valid():
form.save()
return redirect('/')
context = {'form': form}
return render(request, 'accounts/order_form.html', context)

def deleteOrder(request, pk):
order = Order.objects.get(id=pk)
if request.method == "POST":
order.delete()
return redirect('/')
context = {'item': order}
return render (request, 'accounts/delete.html', context)

我 models.py：

# Create your models here.
class Customer(models.Model):
name = models.CharField(max_length=200, null=True)
phone = models.CharField(max_length=200, null=True)
email = models.CharField(max_length=200, null=True)
date_created = models.DateTimeField(auto_now_add=True, null=True)
def __str__(self):
return self.name
class Tag(models.Model):
name = models.CharField(max_length=200, null=True)
def __str__(self):
return self.name
class Product(models.Model):
CATEGORY = (
('Indoor', 'Indoor'),
('Out Door', 'Out Door'),
) 
name = models.CharField(max_length=200, null=True)
price = models.FloatField(null=True)
category = models.CharField(max_length=200, null=True, choices=CATEGORY)
description = models.CharField(max_length=200, null=True, blank=True)
date_created = models.DateTimeField(auto_now_add=True, null=True)
tags = models.ManyToManyField(Tag)
def __str__(self):
return self.name
class Order(models.Model):
STATUS = (
('Pending', 'Pending'),
('Out for delivery', 'Out for delivery'),
('Delivered', 'Delivered'),
)
customer = models.ForeignKey(Customer, null=True, on_delete= models.SET_NULL)
product = models.ForeignKey(Product, null=True, on_delete= models.SET_NULL)
date_created = models.DateTimeField(auto_now_add=True, null=True)
status = models.CharField(max_length=200, null=True, choices=STATUS)
def __str__(self):
return self.product.name

Answer 1

很可能你的主 urls.py 中有这样的东西

urlpatterns = [
path('admin/', admin.site.urls),
path('customer/', include('accounts.urls')),
# other...

替换为

urlpatterns = [
path('admin/', admin.site.urls),
path('', include('accounts.urls')), 
# other ... 

请注意，path中没有customer。这样，您将解决customer/customer/问题。

Answer 2

您可以找到呈现不正确 URL 的位置，并查看是使用 url 函数 ({% url ... %}) 还是硬编码的 html。如果在那里使用硬编码的 html，请记住在开头添加斜杠

Answer 3

您的 urls.py 应用程序名称似乎是帐户(我猜是因为模板来自帐户/...但在设置中，您可以定义 ROOT_URLCONF="cmd.urls"。您发布的 urls.py 是否可能不是根，而是由具有客户路径的根 urls.py 导入的？ 只是一个可能的猜测
