Rails initializer for development and production

Question

I have the following code in /config/initializers/chargify.rb

Chargify.configure do |c|
  c.subdomain = 'example'
  c.api_key   = '123xyz'
end

But I have different settings for development and production.

So, how would I have a different set of variables values based on environment?

Answer 1

What about:

Chargify.configure do |c|
  if Rails.env.production?
    # production settings
    c.api_key   = '123xyz'
  else
    # dev. and test settings
    c.api_key   = '123xyz'
  end
end

Better yet, you can reduce duplication with case block:

Chargify.configure do |c|
  c.subdomain = 'example'
  c.api_key   = case
    when Rails.env.production?
      '123xyz'
    when Rails.env.staging?
      'abc123'
    else
      'xyz123'
    end
end

Answer 2

I would create a config file for this (config/chargify.yml):

development:
  subdomain: example
  api_key: 123abc
production:
  subdomain: production_domain
  api_key: 890xyz

And then change your Initializer like this:

chargify_config_file = File.join(Rails.root,'config','chargify.yml')
raise "#{chargify_config_file} is missing!" unless File.exists? chargify_config_file
chargify_config = YAML.load_file(chargify_config_file)[Rails.env].symbolize_keys

Chargify.configure do |c|
  c.subdomain = chargify_config[:subdomain]
  c.api_key   = chargify_config[:api_key]
end
