Splitting Routes File Into Multiple Files

Question

I\'m working w/ a Rails 3 application and I want to split up the routes into separate files depending on the subdomain. Right now I have this in my routes.rb file:

Answer 1

We used this in our app:

    config.paths['config/routes'] = Dir["config/routes/*.rb"]

If you try to access config.paths['config/routes'] normally, it returns the relative path to config/routes.rb, so by doing the above you're giving it relative paths to all of the files in your routes folder and removing the reference to config/routes.rb

Answer 2

Add the route file to the app route loading path:

# config/application.rb
config.paths.config.routes << File.join(Rails.root, "config/routes/fooroutes.rb")

Wrap your other route file in a block like this.

#config/routes/fooroutes.rb
Rails.application.routes.draw do |map|
  match 'FOO' => 'foo/bar'
end

Works for me in rails 3.0

Answer 3

In Rails 3.2, config.paths is now a hash, so @sunkencity's solution can be modified to:

# config/application.rb
config.paths["config/routes"] << File.join(Rails.root, "config/routes/fooroutes.rb")

Answer 4

Sunkencity's answer seems to be identical to the following link, but for completeness' sake: https://rails-bestpractices.com/posts/2011/05/04/split-route-namespaces-into-different-files/

Note that routes defined later will override routes defined earlier. However, if you use something like

    config.paths.config.routes.concat(
        Dir[Rails.root.join('config/routes/*.rb')])

you don't know in what order the files will be read. So use

    config.paths.config.routes.concat(
        Dir[Rails.root.join('config/routes/*.rb')].sort)

instead, so you at least know they will be in alphabetical order.
