Important concepts

In a nutshell, GLAMkit allows easy creation of Rich content models. Rich content models contain one or more placeholders. Placeholders represent areas in a template that contain zero or more rich content items.

Rich content models

GLAMkit’s rich content models allow a human editor to add and arrange many Content Items in any order into one or more Content Placeholder slots. This is accomplished using the django-fluent-contents system.

An example of a rich content model could be a Press Release, which could have a “Main” placeholder and a “More information” placeholder. The “Main” placeholder could contain ‘text’, ‘images’, ‘videos’, and so on. The “More information” placeholder may only allow ‘press contacts’ and ‘files’ to be added.

Placeholders are specified in the HTML template that is associated with the rich content model. At render time, each {% render_placeholder %} template tag renders all of the content items as they were added by the editor.

Rich content items

A Content item is (usually) a small Django model for representing a unit of content on a page and can have any fields that a normal Django model has. Each Content Item has at least one associated Content Plugin which specifies how it is to be rendered in a given context and how it is edited in the admin.

The icekit.plugins package contains reference implementations for many types of content that you might need in a project.

Database structure

Content plugins and the rich content models which contain them are related with Django Generic Foreign Keys, which means that there is only one database table for each content plugin. This is unlike CMSes like FeinCMS, which create separate tables for every pair of content plugin and content model.

Pages vs Collections

GLAMkit uses django-fluent-pages to provide a tree of pages for your site. Pages can be arranged in any tree shape. The slug of a page is made up of its slug plus that of its parent.

Pages are meant for ‘permanent’ parts of your site, ie that represent a section of your site, and which may appear in permanent site navigation.

Examples of content that works well as Pages are Homepage, About Us, Press Room, Terms & Conditions, Search.

On the other hand, collections of content don’t normally work well in the page tree, because usually collections need browsing and sorting differently from how they would appear in a tree structure, and besides, a single tree would get cluttered with thousands of individual collection items.

Examples of content that would not work well as Pages (because they are more conveniently modelled as large collections of similar things) are Blog Post, Press Release, User, Artwork, etc.

For collections of content, consider using a more traditional Django model, and maybe define a Page Type and/or Content Plugin for listing/navigating through the collection. GLAMkit provides some collection helpers to aid this process.

The icekit.page_types package contains reference implementations for many types of page types that you might need in a project.
