Question

我正在为用户制作一个简单的应用程序来开会。

my seeds.rb file

marshall = User.create！（姓名：＆＃39; Marshall＆＃39;，电子邮件：＆＃39; lanners.marshall@yahoo.com' ;,密码：＆＃39; 1234567＆＃39;，password_confirmation：＆＃39; 1234567＆＃39;） test_post1 = marshall.meetings.create！（标题：＆＃34; testpost！＆＃34;，时间：＆＃39; 09：00：PM＆＃39;，日期：＆＃34; 2014-01-22＆＃34 ;）

当我运行我的种子文件时，它加载一切正常，当我加载页面时它在视图中工作。我可以看到与会议相关联的用户名。但是，当我用minitest capybara运行我的测试时，我得到了跟随错误。

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'

和错误

test_0002_can update meeting                              0:00:00.716 ERROR
        undefined method `name' for nil:NilClass
        Exception `ActionView::Template::Error' at:

我想知道我做错了什么，因为我跑了它在视图中工作正常但不在测试中。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 file＃model

class User < ActiveRecord::Base
  has_secure_password

  has_many :meetings
  has_many :complaints
end

这是不起作用的测试特征/ meeting_system_test.rb

         I want a working meeting system
         so that people will show up to meetings" do

夹具 meetings.yml

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

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

users.yml里

user:
  email: user@examle.com
  name: user
  password_digest: <%= BCrypt::Password.create('password') %>

admin:
  email: user2@example2.com
  name: user2
  password_digest: <%= BCrypt::Password.create('password') %>

任何人都明白为什么它在视图中工作而不是测试？

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。在会议测试数据中添加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
