Django：“没有安装带有标签'flatpages'的应用程序。”与django-markdown

时间：2015-03-04 10:00:55

标签： python django

我试图在我的Django网站上添加一个功能，该网站实现了由管理员写下一些降价的文章。

我安装了django-markdown，并遵循了本教程： http://pythonhosted.org/django-markdown/

我makemigrations / migrate和runserver，我成功访问了我的网站，但是当我尝试访问管理界面时，我遇到了一个问题： No installed app with label 'flatpages'.

以下是我的要求的内容.txt：

Django==1.7.5
django-markdown==0.8.4
Markdown==2.6
wheel==0.24.0

我认为它是django_markdown模块的flatpages。 我尝试了一些东西，比如添加平板电脑＆＃39;到INSTALLED_APPS。但这并没有解决问题（而且已经在其中已经有了＃django_markdown＆＃39;）。 我对django没有足够的经验来理解我的项目中发生了什么，我需要一些帮助来理解这个问题。 有人可以帮帮我吗？

以下是一些可能有用的附加信息和文件：

它可能是什么，我该怎么办？ 谢谢您的帮助。 ：）

编辑： 问题解决了，但是为了解释模板中的降价，我还必须安装django-markdown-deux：

flatpages应用是part of Django。您需要正确安装它。从官方安装文档：

  

要安装flatpages应用，请按以下步骤操作：

     
      
  1. 通过将'django.contrib.sites'添加到INSTALLED_APPS设置来安装网站框架（如果它尚未存在）。
    2.         

    另外，请确保您已将SITE_ID正确设置为设置文件所代表的网站的ID。这通常是1（即SITE_ID = 1，但如果您使用网站框架来管理多个网站，则可能是其他网站的ID。

         
        

    1. 将'django.contrib.flatpages'添加到您的INSTALLED_APPS设置中。然后：

           

      （a）在您的URLconf中添加一个条目。例如：

      2.    
urlpatterns = patterns('',
    (r'^pages/', include('django.contrib.flatpages.urls')),
)
  

或（b）将'django.contrib.flatpages.middleware.FlatpageFallbackMiddleware'添加到MIDDLEWARE_CLASSES设置。

     
      
  1. 运行命令manage.py migrate。
    2.
