More info:
Rails official API document describes the config_for method as:
Convenience for loading config/foo.yml for the current Rails env.
If we do not want to use a yaml file
We can configure our own code through the Rails configuration object with custom configuration under the config.x property.
Example
config.x.payment_processing.schedule = :daily
config.x.payment_processing.retries = 3
config.x.super_debugger = trueClicking "Copy Code" button will copy the code into the clipboard - memory. Please paste(Ctrl+V) it in your destination. The code will get pasted.

These configuration points are then available through the configuration object:
Rails.configuration.x.payment_processing.schedule # => :daily
Rails.configuration.x.payment_processing.retries # => 3
Rails.configuration.x.super_debugger # => true
Rails.configuration.x.super_debugger.not_set # => nil
