Implementing Content Management Systems with Python Django CMS

Django CMS is a content management system based on Python Django, suitable for quickly building manageable websites. It provides an off-the-shelf, scalable solution that supports initialization of projects through djangocms-installer, or can be manually integrated into existing projects, requiring middleware, template context and static files. Its plug-in system allows custom content modules such as recommended articles and can extend page fields through PageExtension. It also supports user permission management and multilingual sites, which are suitable for developers with Django foundation.

Django CMS is a content management system (CMS) based on the Python Django framework, which allows developers to quickly build manageable websites. If you need to implement a content management system in your project and don't want to build all the features from scratch, Django CMS provides an off-the-shelf, scalable solution.

Installation and basic configuration

Installing Django CMS usually starts with creating a new Django project. You can use djangocms-installer to simplify the initialization process. This tool will help you automatically install and configure necessary dependencies.

 pip install djangocms-installer
djangocms mysite

After executing the command, it will guide you through the database settings, whether to enable CMS functions, whether to install the sample page, and other options. Once done, you have a Django project with basic CMS capabilities.

Need to note:

• Make sure your environment has Python and pip installed.
• It is recommended to use a virtual environment such as venv or pipenv to isolate project dependencies.
• If you already have a Django project, you can also manually integrate Django CMS, but the process is a little more complicated.

Integrate into existing Django projects

If you already have a Django project and want to add CMS functionality, you can install Django CMS manually:

 pip install django-cms

Then add the required app in settings.py and do the database migration:

 INSTALLED_APPS = [
    ...
    'cms',
    'treebeard',
    'menus',
    'sekizai',
    'djangocms_admin_style',
    ...
]

Then run:

 python manage.py migrate

This part of the operation is relatively standardized, but the error-prone places are in the middleware, template context processor, and static file settings. for example:

• Make sure 'cms.middleware.user.CurrentUserMiddleware' is in the middleware list.
• 'sekizai.context_processors.sekizai' is to be added to the template context.
• The static file directory must be able to load front-end resources correctly.

Custom pages and plugins

One of the big advantages of Django CMS is its plug-in system. You can add text, pictures, videos and other content blocks to the page, all of which are implemented through plug-ins. If you want to customize the content type, you can do it by creating your own plugin.

For example, if you want to add a "Recommended Articles" module, you can do this:

1. Create a new Django application, such as recommended_articles
2. Create plugin classes using CMSPluginBase
3. Register the plugin and render data in the template

In this way, the administrator can drag and drop the plugin you developed on the page.

In addition, you can also expand the page model and add additional fields, such as meta description, author information, etc. This part is implemented through PageExtension and is suitable for scenarios where page attributes need to be enriched.

User permissions and multilingual support

Django CMS supports fine-grained user permission management. You can set different editing permissions for different roles, such as only allowing editing of specific pages or columns. This is very useful for teamwork.

At the same time, it also has built-in multi-language support. You can configure the supported language list in settings.py , and the system will automatically handle the multilingual version switching of the page.

 LANGUAGES = [
    ('en', 'English'),
    ('zh', 'Chinese'),
]

It should be noted that the translation content needs to be filled in separately, and the URL structure will also change according to the language. If you plan to build an international site, this part of the logic needs to be planned in advance.

Basically that's it. Django CMS is a powerful but slightly complex tool, suitable for developers with a certain Django foundation. As long as it is properly configured, it can significantly reduce the workload of repeated developments.
