Django3.1Specifying a namespace in include()异常

Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.
    
     翻译一下:include（）不支持仅指定namespace而不提供app_name。在include的模块中，设置app_name属性，或者传递一个包含模式列表和app_name的2元组。

源码可知：include(arg,namespace=None),其中arg类型为元组tuple类型

改为元组写法：

from django.contrib import admin
    from django.urls import include,path
    
    urlpatterns = [
        path('polls/',include('polls.urls')),
        path('learning_logs/',include(('learning_logs.urls','learning_logs'),namespace='learning_logs')),
        path('admin/', admin.site.urls),
    ]

> include((‘learning\_logs.urls’,‘learning\_logs’),namespace=‘learning\_logs’)

# TypeError: login() got an unexpected keyword argument ‘template\_name’ #

《Python 编程从入门到实践》学web应用程序开发。在使用Django提供的默认登录视图来实现登录界面功能时出现报错：TypeError: login() got an unexpected keyword argument 'template\_name’  
原来，作者使用的Django是版本是1.0的，其实现代码为：

from django.contrib.auth import login
    url(r'^login/$',login,{
        'template_name'='users/login.html'},name='login')

Django3.+  
django.contrib.auth.views.LoginView，具体实现为：

from django.conf.urls import url
    from django.contrib.auth.views import LoginView
    urlpatterns = [
        #登录界面  LoginView.as_view后面要加上()
        url(r'^login/$',LoginView.as_view(template_name='users/login.html'),name='login')
    ]
