Question

目前通过奥丁项目课程学习ROR。作为“PROJECT：积极记录建设”的一部分，我设置了三个基本模型：用户，帖子，评论。

在帖子和评论中，我的基本“帖子/评论是有效的”测试失败（错误预期真实性），但所有特定测试都通过，例如PostTest的代码：

require 'test_helper'

class PostTest < ActiveSupport::TestCase
  # test "the truth" do
  #   assert true
  # end

  def setup
    @post = Post.new(title: "Hello World", body: "Hello world, it's nice to 
meet you", user_id: 1)
  end

  test "Post is valid" do
    assert @post.valid?
  end

  test "Post title is not blank" do
    @post.title = ""
    assert_not @post.valid?
  end

  test "Post title is less than 40 char" do
    @post.title = "a"*51
    assert_not @post.valid?
  end

  test "Post body is not blank" do
    @post.body = ""
    assert_not @post.valid?
  end

 test "Post has user_id" do
   @post.user_id = ""
   assert_not @post.valid?
 end
end

我感到困惑的原因是，如果我使用rails console手动创建与上面#setup相同的帖子，那么valid?方法会正确返回true。此外，用户模型设置与#setup和user is valid测试的形式完全相同。我看到的唯一区别是用户has_many :posts作为帖子belong_to :user

对于参考，Post模型是：

class Post < ApplicationRecord
  validates :title, presence: true, length: {maximum: 40}
  validates :body, presence: true
  validates :user_id, presence: true

  belongs_to :user 
  has_many :comments

end

您是否正在为您的用户使用灯具，或者您如何知道ID为1的用户记录？

如果您使用灯具，则应在设置中创建用户：

<div id="delete_department" class="modal custom-modal fade" role="dialog">
            <div class="modal-dialog">
                <div class="modal-content modal-md">
                    <div class="modal-header">
                        <h4 class="modal-title">Delete Department</h4>
                    </div>
                    <div class="modal-body card-box">
                        <p>Are you sure want to delete this?</p>
                        <div class="m-t-20 text-left">
                            <a href="#" class="btn btn-default" data-dismiss="modal">Close</a>
                            <button type="submit" class="btn btn-danger" >Delete</button>
                        </div>
                    </div>
                </div>
            </div>
        </div>
<div id="edit_department" class="modal custom-modal fade" role="dialog">
  <div class="modal-dialog">
      <button type="button" class="close" data-dismiss="modal" (click)="edit(list)">×</button>
      <div class="modal-content modal-md">
          <div class="modal-header">
              <h4 class="modal-title">Edit Department</h4>
          </div>
          <div class="modal-body">
              <form>
                  <div class="form-group">
                      <label>Department Name <span class="text-danger">*</span></label>
                      <input class="form-control" value="IT Management" type="text">
                  </div>
                  <div class="m-t-20 text-center">
                      <button class="btn btn-primary btn-lg" (click)="edit(list)">Save Changes</button>
                  </div>
              </form>
          </div>
      </div>
  </div>
</div>
