Question

我正在使用 django 3.1.7 并按照它创建应用程序文档。我被困在第 3 部分，因为它给出了语法错误。

这里是 urls.py:

from django.urls import path
from polls import views

urlpatterns = [
    path('',views.index, name='index'),
    path('<int:question_id>/', views.detail, name='detail'),
    path('<int:question_id>/results/', views.results, name='results'),
    path('<int:question_id>/vote/', views.vote, name='vote'),
]

错误：

(rookieCoderEnv) C:\Users\ORCUN\OneDrive\Masaüstü\WebDeveloperBootcamp\DjangoProject\rookieCoder>py 
manage.py runserver

"C:\Users\ORCUN\OneDrive\Masaüstü\WebDeveloperBootcamp\DjangoProject\rookieCoder\polls\urls.py", 7号线 path('int:question_id/results/'), views.results, name='results'),

我对名字的遗漏是什么？我该如何解决？

错误在这里：

path('<int:question_id>/results/'), views.results, name='results'),

额外的右括号在传递其他参数之前结束路径方法调用。改为：

path('<int:question_id>/results/', views.results, name='results'),

SyntaxError: polls//urls.py 中的语法无效。为什么我会收到这个错误？
