AttributeError:模块'posts.视图'没有属性'home'

Question

从尼克·沃尔特在Django上的Udemy课程中学习，我正在编写自己的“信用卡修订”应用程序。基本功能已就绪。但现在我正在尝试添加一个博客文章应用程序来配合它。我使用$ python3 manage.py startapp posts成功启动了应用程序。但当我开始填写网址.py，模板和子视图，我的服务器已停止运行。我得到：

File "/home//dev/projects/python/2018-and-2019/CC_Redact/CC_Redact/urls.py", line 10, in

url(r'^$', views.home, name='home'),

AttributeError: module 'posts.views' has no attribute 'home'

这是Django2.0和Python3.6，使用内置的测试服务器（还没有接近生产环境的地方）。我在一个激活的虚拟环境中运行我的代码。这些是我的要求.txt公司名称：

Django==2.0.13

Pillow==5.4.1

psycopg2==2.7.7

psycopg2-binary==2.7.7

pytz==2018.9

很基本，对吧？在

网址.py在我的主项目文件夹中：

from django.contrib import admin
from django.urls import path
from . import views
from posts import views


urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', views.home, name='home'),
    url(r'^result/', views.result, name='result'),
    url(r'^james/', views.posts, name='james'), 

视图.py（应用程序文件夹中）：

^{pr2}$

如您所见，我将函数命名为“james”，以及我的模板。在

以下是帖子/模板/帖子/詹姆斯.html：

^{pr2}$

最后，这里是我的文件树和目录结构：。在

当运行服务器时，我希望看到“你在詹姆斯的岗位上！”导航到时以粗体文本显示localhost:8000/个帖子。相反，我收到了：

你真的需要把更多的精力放在课程上。 视图.posts指有一个名为posts的def称为def。 简言之视图.posts调用视图中的posts def。在

改变

def James(request):

到

def posts(request)：

在视图.py 你还需要一个名为“家”的定义
