The way I like to keep my local environment in a rails app.
You know sometimes we need to keep our config variables locally and the best way(at least to me) is the following: 1. Create YAML file with our local variables in config/local_env.yml
local_env.yml example
2. Add following to config/application.rb
##
# Loads local env.
#
config.before_configuration do
env_file = File.join(Rails.root, 'config', 'local_env.yml')
YAML.load(File.open(env_file)).each do |key, value|
ENV[key.to_s] = value
end if File.exists?(env_file)
end
3. Now you can call you local variables from any place in your application like the following: ENV["PAYPAL_CLIEN_ID"]
**IMPORTANT: Make sure not to share local_env.yml on any online repositories for security reasons.
