Configuring variables depending on current Rails.env

Question

What would be the most simple way to configure different variables(for ex. i have variable in tag link_to, which changing, depending on current Rails.env) ?

<%
    if Rails.env == 'development'
        domain = 'somedomain.me'
    elsif Rails.env == 'staging'
        domain = 'example.com'
    end 
    %>
    <%= link_to 'Back', root_url(:subdomain => 'www', :domain => domain), :class=>"btn btn-primary"%>

I want to move this if - elsif statement to somewhere else, or even drop it for some kind of 'configuration files' if any exists

Can you update your question with specific examples of what you're trying to accomplish? — Chris Peters, Dec 19 '12 at 14:07

There's an awesome gem for just this, called rails_config: github repo

But if you just want to configure this and only this variable, you could create a constant at the environment configuration files that rails already has.

Something like:

In your config/environments/production.rb

# production.rb
Rails.configuration.my_awesome_changing_domain = "somedomain.me"

In your config/environments/development.rb

# development.rb
Rails.configuration.my_awesome_changing_domain = "stackoverflow.com"

In your config/environments/staging.rb

# staging.rb
Rails.configuration.my_awesome_changing_domain = "news.ycombinator.com"

Other methods to do that are discussed in another answers, at this thread: https://stackoverflow.com/a/5053882
