我已经设置了项目、任务和子任务，所有这些都是可评论的。我创建了评论模型并连接了模型，但不知道如何正确验证用户 ID 以及如何使用 Rpsec 和 Factory Girl 测试模型代码。我也在使用设计。

评论迁移

  1 class CreateComments < ActiveRecord::Migration
  2   def change               
  3     create_table :comments do |t|   
  4       t.references :user, :null => false
  5       t.text :comment,  :null => false,
  6                         :limit => 500                   
  7       t.references :commentable, :polymorphic => true
  8         # upper line is a shortcut for this
  9         # t.integer :commentable_id     
 10         # t.string :commentable_type    
 11       t.timestamps         
 12     end                    
 13     add_index :comments, :user_id   
 14     add_index :comments, :commentable_id
 15   end
 16 end

评论模型

1 class Comment < ActiveRecord::Base
  2         
  3   # RELATIONSHIPS   
  4   belongs_to :commentable, :polymorphic => true
  5   belongs_to :user
  6   # VALIDATIONS            
  7   validates :user, :presence => true
      validates :commentable, :presence => true
  8   validates :comment, :presence => true,
  9                       :length => { :maximum => 500 }  
 10 
 11   # ATTRIBUTE ASSIGNMENT   
 12   attr_accessible :comment 
 13   
 14 end

用户模型

  1 class User < ActiveRecord::Base
  2         
  3   # RELATIONSHIPS   
  4   has_many :synapses, :dependent => :destroy
  5   has_many :projects, :through => :synapses
  6 
  7   has_many :vesicles, :dependent => :destroy
  8   has_many :tasks, :through => :vesicles
  9 
 10   has_many :subvesicles, :dependent => :destroy
 11   has_many :subtasks, :through => :subvesicles, :dependent => :nullify
 12   
 13   has_many :comments, :dependent => :destroy
 14   
 15   # VALIDATIONS
 16   validates :name,  :presence => true,
 17                     :uniqueness => true             
 18 
 19   # ATTRIBUTE ASSIGNMENT   
 20   attr_accessible :name, :email, :password, :password_confirmation, :remember_me
 21 
 22   # DEVISE MODULES         
 23   # Include default devise modules. Others available are:
 24   # :token_authenticatable, :encryptable, :lockable, :timeoutable and :omniauthable
 25   devise :database_authenticatable, :registerable,
 26          :recoverable, :rememberable, :trackable, :validatable,
 27          :confirmable      
 28 
 29 end

评论工厂

105   factory :comment do
106     comment "This is some generic comment with some generic content"
107   end

评论型号规格

  1 require 'spec_helper'      
  2         
  3 describe Comment do
  4 
  5   it 'Should create new comment' do
  6     FactoryGirl.build(:comment).should be_valid
  7   end                      
  8 
  9   it 'Should respond to method provided by polymorphism to find its parent' do
 10     FactoryGirl.build(:comment).should respond_to(:commentable)
 11   end                      
 12 
 13 end

此第一个测试当前失败，错误消息为 #Comment:0xa88c354> 的未定义方法“用户”。但是如果我像这样传递用户ID......

FactoryGirl.build(:comment, :user => confirmed_user).should be_valid

比我应该将用户 ID 设置为可批量分配的属性，而我不希望这样（认为某些用户可能会弄​​乱该属性并更改它）。如何正确测试和验证这一点？另外，这是我第一次做多态，所以如果你看到任何愚蠢的事情，请告诉我。

编辑。我现在已经按照建议的一个答案这样做了。不幸的是，它返回相同的错误。

  5   it 'Should create new comment' do
  6     confirmed_user = FactoryGirl.build(:confirmed_user)
  7     FactoryGirl.build(:comment, :commentable => confirmed_user).should be_valid 
  8   end

尝试替换：

:user => confirmed_user

和：

:commentable => confirmed_user

升级版：

validates :user, :presence => true

还必须是：

validates :commentable, :presence => true

模型评论应该有：

belongs_to :user
