You can apply settings in Racket in two ways.
a) Globally
settings = { setting_1: 'value_1', setting_2: 'value_2' }
run Racket::Application.using(settings)b) For a specific controller
class MyController
setting :setting_1, 'value_1'
setting :setting_2, 'value_2'
end❗ Use symbols for setting keys, setting values may be any ruby object.
All global settings are inherited by the controllers, so if you want to have a set of default settings but want to have other settings on a specific controller you can combine the methods above.
This is the current list of built-in settings that Racket understands. You are not limited to these, you can add custom settings you like (both globally and on a per-controller-basis) by just using a settings name that does not appear in the list below.
