Application hooks (“apphooks”)¶
An Application Hook, usually simply referred to as an apphook, is a way of attaching the functionality of some other application to a django CMS page. It’s a convenient way of integrating other applications into a django CMS site.
For example, suppose you have an application that maintains and publishes information
about Olympic records. You could add this application to your site’s
the django CMS URLs pattern), so that users will find it at
However, although it would thus be integrated into your project, it would not be fully integrated into django CMS, for example:
- django CMS would not be aware of it, and - for example - would allow your users to create a CMS page with the same
/recordsslug, that could never be reached.
- The application’s pages won’t automatically appear in your site’s menus.
- The application’s pages won’t be able to take advantage of the CMS’s publishing workflow, permissions or other functionality.
Apphooks offer a more complete way of integrating other applications, by attaching them
to a CMS page. In this case, the attached application takes over the page and its URL
(and all the URLs below it, such as
The application can be served at a URL defined by the content managers, and easily moved around in the site structure.
The Advanced settings of a CMS page provides an Application field. Adding an apphook class to the application will allow it to be selected in this field.
Multiple apphooks per application¶
It’s possible for an application to be added multiple times, to different pages. See Attaching an application multiple times for more.
Also possible to provide multiple apphook configurations:
You may require the same application to behave differently in different locations on your site. For example, the Olympic Records application may be required to publish athletics results at one location, but cycling results at another, and so on.
An apphook configuration class allows the site editors to create multiple configuration instances that specify the behaviour. The kind of configuration available is presented in an admin form, and determined by the application developer.
