Python编程从入门到实践-18章映射url:AttributeError: module ‘learning_logs.views‘ has no attribute ‘index‘
Python编程从入门到实践-18章映射url:AttributeError: module ‘learning_logs.views’ has no attribute 'index’和django.core.exceptions.ImproperlyConfigured: Passing a 3-tuple to include()报错
问题描述：
Python编程从入门到实践-18章映射url:AttributeError: module ‘learning_logs.views’ has no attribute 'index’和django.core.exceptions.ImproperlyConfigured: Passing a 3-tuple to include()报错
原因分析：
主要是Python编程从入门到实践书中使用Django1.1实验，目前安装Djang2.0，两个版本存在语法差异
解决方案：
网上看了很多教程最终解决方法：
learning_log\urls.py
from django.urls import path, include
from django.contrib import admin
urlpatterns = [
path(‘admin/’, admin.site.urls),
path(’’, include(‘learning_logs.urls’,namespace=‘learning_logs’)),
]
修改完成后：在earning_logs文件夹中新建urls.py文件：
“”“定义learning_logs的URL模式”""
from django.urls import path
from . import views
app_name = ‘learning_logs’
urlpatterns = [
# 主页
path(r’’, views.index, name=‘index’),
]
此时运行服务器：python manage.py runserver
报错：AttributeError: module ‘learning_logs.views’ has no attribute ‘index’
是因为learning_logs.views’ 没用定义 'index’函数，只是不用管往下一步章节做，就会创建 ‘index’函数，
或者打开learning_logs中的’view.py’
修改：
from django.shortcuts import render
from .models import Topic
def index(request):
“”“The home page for Learning Log.”""
return render(request, ‘learning_logs/index.html’)
而后成功运行服务器
