Devise, undefined local variable or method current_user-Collection of common programming errors

I have Project controller and rspec file for it. I’m usig current_user helper in this way:

# projects_controller_spec.rb

describe "user signed in" do
  before(:each) { sign_in @user }
  after(:each)  { sign_out @user}

  describe "GET index" do      
    it "assigns all projects as @projects" do
      project = FactoryGirl.create(:project, :user => current_user)
      get :index, {}, valid_session
      assigns(:projects).should eq([project])
    end
  end
  ...
end

The helpers sign_in and sign_out seem to work fine but I’v got an error on current_user:

undefined local variable or method `current_user'

What might be a problem, how to fix it?

1. It’s normal. You should create a User instance. You could use let like this :

   # projects_controller_spec.rb
   
   describe "user signed in" do
   
     let(:user) {FactoryGirl.create(:user)}
     before(:each) { sign_in user }
     after(:each)  { sign_out user}
   
     describe "GET index" do      
       it "assigns all projects as @projects" do
         project = FactoryGirl.create(:project, :user => user)
         get :index, {}, valid_session
         assigns(:projects).should eq([project])
       end
     end
     ...
   end
   

   You know than the current_user is user …

   You don’t need to sign out your use after each spec.
