Namespaced Resources with Merb

Last weekend there were a few people in #merb having issues with namespaced resources, myself included. The example code in the docs ends up adding an extra ‘namespace’ to the urls, so we ended up with a rather ugly block of code to do the routing. Tonight I decided to take a look again at the issue and found another way that works much better. It is now one much shorter line of code for each resource,

r.resources :bars, :namespace => 'foo'

along with the usual wrapping your controllers in ‘module Namespace’. Full example below.

One catch is views always look in /views/namespace/controller, while the controller itself can be picked up in either /controllers or /controllers/namespace. I like the cleanliness of the subfolders so I’m not going to complain.

Example

/config/router.rb

r.resources :bars, :namespace => 'foo'

/app/controllers/foo/bars.rb

module Foo
  class Bars < Application

    def index
      render
    end
  end
end

/app/views/foo/bars/index.html.erb

Hello Namespace

Named routes generated for use with url()

new_foo_bar: /foo/bars/new
edit_foo_bar: /foo/bars/:id/edit
custom_foo_bar: /foo/bars/:action/:id
foo_bars: /foo/bars
foo_bar: /foo/bars/:id
