Horizon themes are now configurable at a user level, through the use of cookies. The themes that can be set are configurable at a deployment level through settings.py. Horizon can be configured to run with multiple themes, and allow users to choose which themes they wish to run. Django Compressor: In order to support dynamic themes, each theme configuration must be pre-compiled through the Django compressor. By making use of its built in COMPRESS_OFFLINE_CONTEXT, we now return a generator to create each of the theme's necessary offline contexts. Templates: Horizon themes allowed template overrides via their 'templates' subfolder. In order to maintain this parity, a custom theme template loader was created. It is run before the other loads, and simply looks for a Django template in the current theme (cookie driven) before diverting to the previous template loaders. Static Files: Horizon themes allowed static overrides of the images in 'dashboard/img' folder. A template tag, 'themable_asset' was created to maintain this parity. Any asset that is wished to be made themable, given that it is located in Horizon's 'static/dashboard' folder, can now be made ot be themable. By making this a template tag, this gives the developers more granular control over what branders can customize. Angular and Plugins: By far, the trickiest part of this task, Angular and Plugins are dynamic in the files that they 'discover'. SCSS is not flexible in this manner at ALL. SCSS disallows the importation of a variable name. To get around this, themes.scss was created as a Django template. This template is the top level import file for all styles within Horizon, and therefore, allows ALL the scss files to share a common namespace and thus, can use shared variables as well as extend shared styles. Other: This change is fundamental, in that it changes the method by which Horizon ingests its SCSS files. Many problems existing in the previous implementation, in an effort to make Horizon flexible, its SCSS was made very inflexible. This patch corrects those problems.

The following 'include' is used to allow all scss files to share the same variable namespace
|
|
and also have access to ALL styles so that we can allow @extend functionality to persist.
|
|
|
|
If you wish to add new scss files, it is recommended that you add them from within the
|
|
themes/themes.scss template file.
