我的 ApplicationController 中有以下代码:

application_controller.rb

class ApplicationController < ActionController::Base
 protect_from_forgery
 include SessionsHelper  
end

应用程序/helpers/sessions_helper.rb

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

我正在使用 rspec-rails 并在我的实用程序.rb 文件中使用了辅助方法“sign_in”:spec/support/utilities.rb

def sign_in(user)
 visit signin_path
 fill_in "Email",with:user.email
 fill_in "Password",with:user.password
 click_button 'Sign in'
 cookies[:remember_token]=user.remember_token
end

我的 static_pages_spec 看起来像这样:

 describe "When signed in" do
  let(:user) {FactoryGirl.create(:user)}
  before do
    sign_in user
  end
  describe "When no lists are present" do

    it "should show message asking to create list" do
      page.should have_selector("div",text:"You have no lists ! Create a list now !")
    end
  end
 end

当我运行测试时,它给了我这个错误:

StaticPages 主页 登录时 没有列表时应显示要求创建列表的消息
     失败/错误:登录用户
     无方法错误:
       未定义的方法sign_in'visit' for #<SessionsController:0x00000003630c10>
     # ./spec/support/utilities.rb:2:in
     # ./app/controllers/sessions_controller.rb:13:in click_button'create'
     # (eval):2:in
     # ./spec/support/utilities.rb:5:in block (4 levels) in top (required)>'
sign_in'
     # ./spec/requests/static_pages_spec.rb:24:in

这是 SessionsController 的“创建”动作:

def create
 user = User.find_by_email(params[:session][:email])
 if user && user.authenticate(params[:session][:password])
   sign_in user  # CODE ERRORS OUT HERE..sign_in of spec/support/utilities.rb executed
   redirect_back_or
 else
   flash.now[:error]= "Invalid email/password"
   render 'new' ,layout: "signin_fail"
 end
end

TL,DR:所以,我的 SessionsController 执行了错误的“sign_in”方法(属于规范/支持而不是 app/helpers.session_helper.rb 的方法)。当我将规范/支持中的助手名称更改为 "log_in" 时,问题就会得到解决。这里可能是什么问题?
