测试 capybara minitest 嵌套资源时出错

Question

我正在为用户制作一个简单的应用程序来召开会议。

我的种子.rb 文件

marshall = User.create!(name: 'Marshall', email: 'lanners.marshall@yahoo.com'，密码：'1234567'，密码确认：'1234567'） test_post1 = marshall.meetings.create!(title: "testpost!", time: '09:00:PM', date: "2014-01-22")

当我运行我的种子文件时，它会加载一切正常，并且当我加载页面时它在视图中工作。我可以看到与会议关联的用户名。但是，当我使用 minitest capybara 运行测试时，出现以下错误。

test_0005_can destroy meeting                             0:00:01.131 ERROR
        undefined method `name' for nil:NilClass
        Exception `ActionView::Template::Error' at:
        app/views/meetings/index.html.erb:44:in `block in _app_views_meetings_index_html_erb___3264872258283250738_70171632466460'

还有错误

test_0002_can update meeting                              0:00:00.716 ERROR
        undefined method `name' for nil:NilClass
        Exception `ActionView::Template::Error' at:
        app/views/meetings/show.html.erb:4:in `_app_views_meetings_show_html_erb___1801038855426537038_70299721197600'

我想知道我做错了什么，因为我运行它在视图中运行良好，但在测试中却不行。以下是我的一些文件，可以帮助你们了解我做错了什么。

会议/index.html.erb

<% @meetings.each do |meeting| %>
  <tbody>
    <tr>
           #below is line 44
      <td><%= meeting.user.name %></td>
      <td><%= meeting.title %></td>
      <td><%= meeting.time.strftime("%l:%M %p") %></td>
      <td><%= meeting.date %></td>
      <td><%= link_to "show page", meeting %></td>
      <td><%= link_to "edit meeting", edit_meeting_path(meeting) %></td>
      <td><%= link_to "destroy", meeting, method: :delete, data: {confirm: 'are you sure'} %></td>
    </tr>
  </tbody>

schema.rb 文件

  create_table "meetings", force: true do |t|
    t.string   "title"
    t.time     "time",       limit: 255
    t.datetime "created_at"
    t.datetime "updated_at"
    t.date     "date"
    t.integer  "user_id"
  end

  create_table "users", force: true do |t|
    t.string   "email"
    t.string   "name"
    t.string   "password_digest"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

end

meeting.rb 文件#model

class Meeting < ActiveRecord::Base
  has_many :complaints
  belongs_to :user
  validates :title, :time, :date, presence: true
end

user.rb 文件#模型

class User < ActiveRecord::Base
  has_secure_password

  has_many :meetings
  has_many :complaints

夹具 会议.yml

one:

  password_digest: <%= BCrypt::Password.create('password') %>

有人明白为什么它在视图中工作而不是在测试中工作吗？

Answer 1

您收到此错误是因为您的会议记录没有与之关联的用户记录。您可以轻松添加它。在您的会议测试数据中添加您想要与会议关联的用户记录。因此，在您的 test/fixtures/meetings.yml 文件中包含以下内容：

one:
  title: MyString
  time: 03:00:PM
  date: 2014-01-14
  user: user

two:
  title: MyString
  time: 05:00:AM
  date: 2014-01-11
  user: admin
