ruby-on-rails – Rails：删除capybara,bug或我的错误请求？

describe "when signing in again" do
        before do
          delete signout_path
          print page.html <---- Insert this here
          visit signin_path
          print page.html <---- Insert here again
          fill_in "Email",with: user.email
          fill_in "Password",with: user.password
          click_button "Sign in"
        end

        it "should render the default (profile) page" do
          page.should have_selector('title',text: user.name) 
        end
      end

我插入了这两个版画.而且,令人惊讶的是我得到了同一页面的打印输出(不应该是这样,它应该在发送DELETE请求后将你带回根URL).发生这种情况后,由于访问signin_path会将我带回登录页面,因此登录过程会成功,测试用例也会成功.但是,第二个打印page.html给了我一个仍然登录的用户的标题.

当我将delete signout_path更改为click_link“退出”时,它工作正常.

我错过了我的代码中的某些内容,或者它是Capybara的错误吗？ (因为我很确定我跟着一切正确……)

更新：
如果我将删除signout_path更改为Capybara.current_session.driver.delete signout_path它也可以正常工作. (意思是水豚用户正确签名)

UPDATE

这些是文件(会话控制器和帮助程序)：

sessions_controller.rb

class SessionsController < ApplicationController

  def new
  end

  def create
    user = User.find_by_email(params[:session][:email].downcase)
    if user && user.authenticate(params[:session][:password])
      sign_in user
      redirect_back_or user
    else
      flash.now[:error] = 'Invalid email/password combination'
      render 'new'
    end
  end

  def destroy
    sign_out
    redirect_to root_url
  end

end

sessions_helper.rb

module SessionsHelper
  def sign_in(user)
    cookies.permanent[:remember_token] = user.remember_token
    self.current_user = user
  end

  def signed_in?
    !current_user.nil?
  end

  def current_user=(user)
    @current_user = user
  end

  def current_user?(user)
    user == current_user
  end

  def signed_in_user
    unless signed_in?
      store_location
      redirect_to signin_url,notice: "Please sign in."
    end
  end

  def current_user
    @current_user ||= User.find_by_remember_token(cookies[:remember_token])
  end

  def sign_out
    self.current_user = nil
    cookies.delete(:remember_token)
  end

  def redirect_back_or(default)
    redirect_to(session[:return_to] || default)
    session.delete(:return_to)
  end

  def store_location
    session[:return_to] = request.url
  end
end

的routes.rb

DemoApp::Application.routes.draw do
  ...

  root to: 'static_pages#home'

  match '/signup',to: 'users#new'
  match '/signin',to: 'sessions#new'
  match '/signout',to: 'sessions#destroy',via: :delete

  resources :sessions,only: [:new,:create,:destroy]

  ...

end
