Class Method Details

.defined_environments ⇒ Object

NOTE: kept public for backward compatibility - the historic private keyword never applied to def self. methods, so this was always callable.

def self.defined_environments
  @defined_environments ||=
    Dir.glob(Rails.root.join("config", "environments", "*.rb"))
       .map { |filename| File.basename(filename, ".rb").to_sym }
end

.dig(*credentials) ⇒ Object

Fetching Rails encrypted credentials with:

`Rails.application.credentials.dig(:environment, :credential)`

Is too long for my taste. Using Cre.dig is a lot shorter:

`Cre.dig(:environment, :credential)`

By default Rails.env finds the default environment for us when none is specified and it is called with the credential only:

`Cre.dig(:password)`

The dig method here is just an aesthetic thing to keep us in context.
