funktioniert nicht database_cleaner mit Rspec Test

Question

Hallo Leute, ich versuche, Datenbank-Reiniger, aber ich kann das nicht tun und ich weiß nicht, was ich vermisse.

Was ich bisher:

users_controller_spec

require 'rails_helper' 

describe UsersController, :type => :controller do 

    #user = User.create!(email: "test@test.com", password: "123456") 

    user = FactoryGirl.create(:user) 

    describe 'GET #show' do 

    context 'User is logged in' do 
     before do 
     sign_in user 
     end 

     it 'loads correct user details' do 
     get :show, id: user.id 
     expect(response).to have_http_status(200) 
     expect(assigns(:user)).to eq user 
     end 
    end 

    context 'No user is logged in' do 
    it 'redirects to login' do 
     get :show, id: user.id 
     expect(response).to redirect_to(new_user_session_path) 
    end 
    end 

end 
end 

support/database_cleaner.rb

RSpec.configure do |config| 

    config.before(:suite) do 
    DatabaseCleaner.clean_with(:truncation) 
    end 

    config.before(:each) do 
    DatabaseCleaner.strategy = :transaction 
    end 

    config.before(:each, :js => true) do 
    DatabaseCleaner.strategy = :truncation 
    end 

    config.before(:each) do 
    DatabaseCleaner.start 
    end 

    config.after(:each) do 
    DatabaseCleaner.clean 
    end 

end 

rails_helper.rb haben Linie

config.use_transactional_fixtures = false 

und uncommented Linie

Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

Versuchen Sie, diese Linie Umschreiben let zu verwenden:

user = FactoryGirl.create(:user) 

wird

let(:user) { FactoryGirl.create(:user) }
