Overview

The System configuration. Various configuration items that can be updated/defined at run time instead of AppConfiguration that is defining things statically in code.

In hindsight (being 20/20) this should have been named stack_configuration as now the stack UI is what allows the administrator to update/configure this information.

Use of this class allows you to simply ask for the configuration parameter directly without first having to get an instance of it.

SystemConfiguration.queue_impl #=> ‘RedisQueue’

This method only is allowed for accessors, you should NEVER set values on the SystemConfiguration unless you are updating via the Admin or Stack UI, or during testing to setup a specific configuration for that.

Class Method Details

.configuration ⇒ Object

Fetch the system configuration based on environment name. First try the rails cache if not there, then go to the database.

Also, if an argument error is thrown, then just fetch from the database.
