Namespace routing
The new RSpec method, before, takes a block of code that’s executed before every
spec inside the current context or describe.
You use the lengthy let(:user) block again, which is effectively the same as what
you have in spec/controllers/projects_controller_spec.rb. Rather than duplicating the
code inside this block, move it into a new file in your spec/support directory. Its job is
to provide methods to help you seed your test data, so call it seed_helpers.rb. In this
file, create a module called SeedHelpers, which contains a create_user! method that
uses the code from the let. This file is shown in the following listing.
Listing 7.17 spec/support/seed_helpers.rb
module SeedHelpers
def create_user!(attributes={})
user = Factory(:user, attributes)
user.confirm!
user
end
end
RSpec.configure do |config|
config.include SeedHelpers
end
With this new spec/support/seed_helpers.rb file, you can now use create_user!
rather than the three lines of code you’re currently using. Let’s change the
let(:user) in spec/controllers/projects_controller_spec.rb to this:
let(:user) { create_user! }
Ah, much better! Let’s also change it in the new spec/controllers/admin/users
_controller_spec.rb file:
let(:user) { create_user! }
When you run this spec file using bin/rspec spec/controllers/admin/users
_controller_spec.rb, you see that there’s no route to the index action:
1) Admin::UsersController regular users are not able to access the
➥index action
Failure/Error: get 'index'
No route matches {:controller => "admin/users"}
In fact, there’s no route to the controller at all! To define this route, open config/
routes.rb and insert the following code before the final end in the file.
Listing 7.18 config/routes.rb
namespace :admin do
resources :users
end
This code defines similar routes to the vanilla resources but nests them under an
admin/ prefix. Additionally, the routing helpers for these routes have an admin part to
