AppConfig is a gem that allows you to create an config/app_config.yml file in a Rails project and access the keys and values as a hash throughout the project.
This gem is excellent for storing Rails-wide constants.
The App constants should be stored in one or both of the following files (exact filenames are required): config/app_config_default.yml config/app_config.yml
The AppConfig app should be loaded in the initializers directory. Here is an example file:
#config/initializers/app_config.rb
require "app_config"
AppConfig.reload(Rails.env, Rails.root)Here is an example of what the config/app_config.yml can look like:
defaults: &default
gmail:
email: "[email protected]"
password: "something"There are two methods to access the email:
#Normal method
AppConfig['gmail']['email']
#Shortcut method
GmailConfig['email']The shorcut method only works one level deep.
