Rails%203%20In%20Action

Restricting actions to admins only
projects_controller_spec.rb, and add a let inside the describe so the top of the spec
looks like the following listing.
describe ProjectsController do
let(:user) do
user = Factory(:user)
user.confirm!
user
end
context "standard users" do
it "cannot access the new action" do
sign_in(:user, user)
end
end
...
end
Listing 7.3 spec/controllers/projects_controller_spec.rb
Here you use a multilined block for the let method. This method defines a user
method, which returns a newly created and confirmed user. You create this user using
Factory Girl.
You then use this object in your test to sign in as that user. The benefit of using let
over defining an instance variable in a before block is that the let code is called only
when it’s referenced, whereas all the code in a before is evaluated regardless. This is
helpful if some of your tests don’t need a User object.
Underneath the let, you add a short placeholder test that signs in as the user,
attempting to use the userlet method. With this test, the let block is called, and you
should get an error when you run this spec using bin/rspec spec/controllers/
projects _controller_spec.rb:
Not registered: user (ArgumentError)
Therefore, you should create a user factory that creates a user object with a random
email address (because you may wish to create more than one user at a time using this
factory), and the password should default to password. Define this factory in a new file
called factories/user_factory.rb:
Factory.define :user do |user|
user.sequence(:email) { |n| "user#{n}@ticketee.com" }
user.password "password"
user.password_confirmation "password"
end
In this factory, you use the sequence method provided by Factory Girl, which passes a
unique number to the block and makes your user’s email addresses unique.
The files within the factories directory aren’t yet required by RSpec, so their factories
aren’t available for you. To make RSpec load them, create a new file at spec/support
/factories.rb and put this content in it:
