Question

我正在使用Django创建一个博客。我得到这个错误'set'对象是不可逆的。请让我知道，为什么我遇到这个错误以及如何解决它？

这是我的 urls.py 文件：

from django.conf.urls import url
from django.contrib import admin
from django.urls import path , include
from . import views
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^about/$',views.about),
    url(r'^$', views.homepage),
    url(r'^Home/', include('Home.urls')),
]

Answer 1

from django.contrib import admin
from django.urls import path , include
from . import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('about/', views.about), 
    path('', views.homepage, name="index"), 
    path('Home/', include('Home.urls')),
]

我这是因为你使用url而不是路径。在Django 2.0中，网址更改为path。

Django'设置'对象是不可逆的。不知道为什么？
