使用参数'（）'和关键字参数'{}'找不到'index'

我在加载索引页面时遇到问题，我已经尝试了两天，但它对我不起作用。

错误：

Reverse for 'index' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

my views.py：

def index(request):
    invoices = 
    InvoiceHeaders.objects.filter(user=request.user.id).order_by('-
    status', 'number')
    return render(request, 'invoices/index.html' ,
                          {'invoices' : invoices,
                          'current_site' : request.META['HTTP_HOST'],
                          'current_path' : request.META['PATH_INFO'],
                          'r' : request.path , })

我的发票网址：

from django.conf.urls import url, include
from django.conf import settings


from . import views 

app_name = 'invoices'

urlpatterns = [

    url(r'^$', views.index,  name='index'),
    url(r'^new/$', views.new,  name='new'),  

]

我的基本网址：

urlpatterns = [

    url(r'^invoices/',  include('invoices.urls',  
    namespace='invoices')),


   ]

答案 0 :(得分：2)

该错误表明您的模板中某处{% url 'index' %}。

它应该是{% url 'invoices:index' %}和其他地方一样。

这可能在您未展示的base.html中。

答案 1 :(得分：0)

我不知道您如何传递浏览器网址，但尝试将您的网址（r'^ $'，views.index，name ='index'）更改为网址（r'^ index / $'， views.index，name ='index'），

我建议您查看您的网址格式
