Question

我正在尝试为我的rails应用程序编写一些视图规范，但我偶然发现了这个错误：

ActionView::Template::Error:
       undefined local variable or method `current_user' for #<#<Class:0x007fa47d2612d0>:0x007fa47e267710>

以下是我编写视图规范的方法：

describe "/newsletters/index.html.erb" do
  include NewslettersHelper
  include Authlogic::TestCase

  def current_user(stubs = {})
    @current_user ||= mock_model(User, stubs)
  end

  def user_session(stubs = {}, user_stubs = {})
    @current_user_session ||= mock_model(UserSession, {:user => current_user(user_stubs)}.merge(stubs))
  end



def login(session_stubs = {}, user_stubs = {})
    UserSession.stub!(:find).and_return(user_session(session_stubs, user_stubs))
  end



 def logout
    @user_session = nil
  end



context "without a logged-in user" do
    before(:each) do
      activate_authlogic
      logout()
      assigns[:newsletters] = @newsletters = [ mock_model(Newsletter, :titre => "value for titre",
       :sommaire => "value for sommaire", :content => "value for content") ]
    end

it "renders a list of newsletters" do
  # pending("find how to mock authlogic current user in views spec")
  render
  rendered.should have_selector("tr>td") do |row|
    row.should have_content("value for titre")
  end
  rendered.should have_selector("tr>td") do |row|
    row.should have_content("value for sommaire")
  end
  rendered.should have_selector("tr>td") do |row|
    row.should have_content("value for content")
  end
end

Answer 1

尝试controller.stub(:current_user) { mock_model(User) }我认为应该有所帮助

Answer 2

视图规范是一个独立的上下文，因此您需要在视图上下文中存根current_user方法。

view.stub(:current_user).and_return(mock_model(User))

如需进一步阅读查看规范，建议您view spec page津津乐道

没有一个答案对我有用（在这里使用 rspec 3.9），因为我收到了像 #<#<Class:0x007fb9ca387dc8> does not implement: current_user 这样的错误，试图存根视图或控制器对象，所以我不得不这样做：

  before do
    controller.singleton_class.class_eval do
      # Just defining methods to being stubbed later
      def current_user; end
      def current_account; end
      helper_method :current_user, :current_account
    end
    allow(controller).to receive(:current_user).and_return(user)
    allow(controller).to receive(:current_account).and_return(account)
  end

不是最漂亮的解决方案，但它奏效了。
