Ruby on rails Rspec测试验证页面无法'；不及格

我将在第8章中介绍ROR教程。我一直在测试身份验证页面。这本书我已经查了三遍，没有发现任何问题。任何人请看一看，您的帮助将不胜感激

会话\u controller.rb文件：

  class SessionsController < ApplicationController
    def new
    end
def create
    user = User.find_by(email: params[:session][:email].downcase)
    if user && user.authenticate(params[:session][:password])
    else
        flash.now[:error]= 'Invalid email/password combination' # Not quite right!
        render 'new'
    end
end
    def destroy
    end
end

我认为A开头是对的，看起来应该是小写。我还看了一眼

它也是小写的。根据David Flanagan，Yukhiro Matsumoto的Ruby编程语言书，请确保我也检查了Ruby是一种区分大小写的语言。

谢谢！它是小写的hehe@Snailwalker这可能是因为您缺少sample_app/app/views文件夹（可能是sample_app/app/views/sessions/new.html.erb模板），或者您可能需要在控制器中添加渲染方法调用。很抱歉，我没有您的代码，但我希望此链接将有助于进一步：

  class SessionsController < ApplicationController
    def new
    end
def create
    user = User.find_by(email: params[:session][:email].downcase)
    if user && user.authenticate(params[:session][:password])
    else
        flash.now[:error]= 'Invalid email/password combination' # Not quite right!
        render 'new'
    end
end
    def destroy
    end
end

SampleApp::Application.routes.draw do
  resources :users
  resources :sessions, only: [:new, :create, :destroy]
  root to: 'static_pages#home'
  match '/signup',  to: 'users#new',            via: 'get'
  match '/signin',  to: 'sessions#new',         via: 'get'
  match '/signout', to: 'sessions#destroy',     via: 'delete'
  match '/help',    to: 'static_pages#help',    via: 'get'
  match '/about',   to: 'static_pages#about',   via: 'get'
  match '/contact', to: 'static_pages#contact', via: 'get'
end

describe "with valid information" do
      let(:user) { FactoryGirl.create(:user) }
      before do
        fill_in "Email",    with: user.email.upcase
        fill_in "Password", with: user.password
        click_button "Sign in"
      end
