TypeError：__ init __（）需要1个位置参数但是2个被赋予django

Question

这是urls.py

from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^/', include('main.urls', namespace='Home')),

]

这是views.py

from django.shortcuts import render,HttpResponse,render_to_response,HttpResponseRedirect
from django.views.generic import TemplateView
from main.models import *

class leaflet(TemplateView):
    template_name = "file.html"

当我编写此代码模板未显示时，会抛出错误：

  

__init__()需要1个位置参数，但有2个被赋予＆＃34;

你能在我的代码中找到错误吗？

Answer 1

您需要在urlpatterns中添加leaflet.as_view（）

urls.py

from django.conf.urls import include, url
from django.contrib import admin
from main.views import leaflet

urlpatterns = [
   url(r'^admin/', include(admin.site.urls)),
   url(r'^/', include('main.urls', namespace='Home')),
   url(r'^test/', leaflet.as_view()),
]

Answer 2

您urls.py应该看起来像

from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^/', include('main.urls'), name='Home'),

]

更新： 如果您使用的是django-1.8或更早版本，则应在app_name函数中添加include参数

url(r'^/', include('main.urls', namespace='Home', app_name='polls'))
