ruby-on-rails - RailsTutorial 登录 flash 不工作

Question

我正在尝试让错误闪现出现在 railstutorial.org 示例应用程序中。到目前为止，这就是我所做的。谁能帮我找出错误:

我的 RSPEC 测试失败:

1) SessionsController POST 'create' invalid signin should have a flash.now message
Failure/Error: flash.now[:error].should =~ /invalid/i
expected: /invalid/i
     got: nil (using =~)
./spec/controllers/sessions_controller_spec.rb:27

Controller 代码:

def create
  user = User.authenticate(params[:session][:email],
  params[:session][:password])
  if user.nil?
    flash.now[:error] = "Invalid email/password combination."
    @title = "Sign in"
    render 'new'
  else
    # Sign the user in and redirect to the user's show page.
  end
end

测试代码:

describe "POST 'create'" do

describe "invalid signin" do

  before(:each) do
    @attr = { :email => "example@gmail.com", :password => "invalid"}
  end 

  it "should re-render the new page" do
    post :create, :session => @attr
    response.should render_template('new')
  end 
  it "should have a flash.now message" do
    post :create, :session => @attr
    flash.now[:error].should =~ /invalid/i
  end 
end

看起来在您的 app/controllers/sessions_controller.rb 中您有一个 second 创建方法在底部声明，它只是说:

def create
  render 'new'
end

第二个声明将取代您在文件前面的预期创建方法。只需删除这三行(您文件中的 20-22 行)，您的规范就会以优异的成绩通过，我的意思是只有一种颜色，即绿色。
