python - 将 django-cms 集成到现有项目中 - 错误 : TemplateDoesNotExist at/news/cms_wizard/create/

Question

我正在尝试将新闻功能添加到现有的 Django 项目中。我决定使用 django-cms 来提供功能。缺少文档，就将 django-cms 集成到现有项目而言，几乎毫无用处。

我看过this question和 this one但所提供的答案只让我走了这么远。

我想要做的是能够拥有包含静态数据的页面，并使用 django-cms 允许具有正确权限的用户创建新页面和/或更新现有页面。

目前，当我运行 python manage.py runserver 并导航到 http://127.0.0.1:8000/news/1/ 时，我得到以下错误信息:

NoReverseMatch at /news/1/ Reverse for 'pages-root' not found. 'pages-root' is not a valid view function or pattern name.

这是我的软件组件的相关版本控制信息:

我有两个问题需要帮助解决:

1. 当我转到 http://127.0.0.1/news/ 时显示的页面没有使用我的网站模板 - 而是使用 django 的模板-厘米。如何更改它以使用我自己的模板？

2. 当我到达 http://127.0.0.1/news/1 时，只显示我的页面标题 - 可编辑的小部件没有移位，我无法输入文本预期的。我该如何解决这个问题？

1. 要解决查找模板的问题，您需要熟悉查找模板的方法。来自documentation :

Loads templates from Django apps on the filesystem. For each app in INSTALLED_APPS, the loader looks for a templates subdirectory. If the directory exists, Django looks for templates in there.

For example, for this setting:

INSTALLED_APPS = ['myproject.polls', 'myproject.music']

… Then get_template ('foo.html') will look for foo.html in these directories, in this order:

 / path / to / myproject / polls / templates /
 / path / to / myproject / music / templates /

... and will use the one it finds first.

由此我们可以得出结论，有必要在 INSTALLED_APPS 中将 'news' 放在 'cms' 之前:

INSTALLED_APPS = [
     ...
    'news',
     ...
     'cms',
     ...
] 

1. 通常文本本身显示在详细信息页面上，无法更改。他们在 admin page 上更改它:

    from django.contrib import admin
    from .news.model import NewsItem
   
    class NewsItemAdmin(admin.ModelAdmin):
         pass
   
    admin.site.register(NewsItem, NewsItemAdmin)
   

如果您需要在您的网站上显示一个页面进行编辑，那么您可以使用 forms .
