Michael Hartl RoR 教程第 3 章，2 个测试错误

Question

我已经坚持了将近 4 个小时。在本章中，我们被要求第一次运行测试。它正在输出两个错误，我不明白它们是什么。

这些是错误：

Finished in 0.097197s, 20.5768 runs/s, 0.0000 assertions/s.



1) Error:
StaticPagesControllerTest#test_should_get_help:
AbstractController::Helpers::MissingHelperError: Missing helper file helpers//users/kevinmulhern/documents/the_odin_project/ruby_on_rails/sample_app/app/helpers/application_helper.rb_helper.rb
    app/controllers/application_controller.rb:1:in `<top (required)>'
    app/controllers/static_pages_controller.rb:1:in `<top (required)>'


  2) Error:
StaticPagesControllerTest#test_should_get_home:
ActionView::MissingTemplate: Missing template static_pages/home, application/home with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in:
  * "/Users/kevinmulhern/.rvm/gems/ruby-2.2.0/gems/web-console-2.0.0.beta3/lib/action_dispatch/templates"
  * "/Users/kevinmulhern/documents/the_odin_project/ruby_on_rails/sample_app/app/views"
  * "/Users/kevinmulhern/.rvm/gems/ruby-2.2.0/gems/web-console-2.0.0.beta3/app/views"

    test/controllers/static_pages_controller_test.rb:5:in `block in <class:StaticPagesControllerTest>'

2 runs, 0 assertions, 0 failures, 2 errors, 0 skips

我最终抓取了该应用程序，因为无论如何我并没有深入了解它，然后复制并粘贴到我卡住的部分，我不认为这可能是导致这种情况的错字。

这是静态页面的控制器

class StaticPagesController < ApplicationController
  def home
  end

  def help
  end
end

最后是测试文件：

require 'test_helper'

class StaticPagesControllerTest < ActionController::TestCase
  test "should get home" do
    get :home
    assert_response :success
  end

  test "should get help" do
    get :help
    assert_response :success
  end
end

任何帮助都将不胜感激。

删除助手后更新错误：

ActionView::MissingTemplate: Missing template static_pages/home, application/home with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in:

    test/controllers/static_pages_controller_test.rb:5:in `block in <class:StaticPagesControllerTest>

更新

我将项目移动到我的主目录，这解决了问题。我的目录结构一定有问题。

Answer 1

对于您的第一个错误，无需查看任何代码或其他任何内容，我可以告诉您：//users/kevinmulhern/documents/the_odin_project/ruby_on_rails/sample_app/app/helpers/application_helper.rb_helper.rb 闻起来很糟糕（注意 application_helper.rb_helper.rb 部分中出现的两个 .rb）更新： 勾选this similar question。

对于第二个，您的错误消息是这样的：ActionView::MissingTemplate: Missing template static_pages/home。看看missing template 是什么意思。 （提示：你有static_pages/home.html.erb 文件吗？）
