使用嵌套对象编写测试时出现 Mogoose 验证错误

学生

我正在编写一个使用 javascript、node、mongoDB 和 mongoose 的小应用程序。我有两个系列；用户和组，其中每个组都包含一组用户

用户：{_id:{type: String, required: true} FirstName: {type: String, required: true}, ..}

组{_id:{type: String, required: true}, users:[{user: userSchema}] }

我正在使用 Mocha 和 Superagent 编写 api 单元测试。当我为包含用户嵌套对象的组插入示例文档时，出现验证错误？

你能告诉我这个例子出了什么问题吗？

var userSchema = 
{
    _id: {
        type: String,
        required: true,
    },
    profile: {
        firstName: {
            type: String, 
            required: true
        },
        lastName: {
            type: String, 
            required: true
        }
}; 

var GroupSchema = 
{
    _id: {
        type: String, 
        required: true
    },
     users:[{
         user: User.userSchema
     }]
};
it('can query group by id', function(done) {
  var users = [
    { _id: 'az', profile: {firstName: 'a', lastName: 'z'}},
    { _id: 'bz', profile: {firstName: 'b', lastName: 'z'}},
  ];

  User.create(users, function(error, users) {
    assert.ifError(error);
    Group.create({ _id: 'ab', users: [{ _id: 'az', profile: {firstName: 'a', lastName: 'z'}}, { _id: 'bz', profile: {firstName: 'b', lastName: 'z'}}] }, function(error, doc) {
    assert.ifError(error);
    var url = URL_ROOT + '/api/groups/id/ab';

    superagent.get(url, function(error, res) {
      assert.ifError(error);
      var result;
      assert.doesNotThrow(function() {
        result = JSON.parse(res.text);
      });
      assert.ok(result.group);
      assert.equal(result.group._id, 'ab');
      done();
    });
  });
  });
});

错误信息：

 Uncaught ValidationError: ChatGroup validation failed: users.1._id: Cast to ObjectID failed for value "bz" at path "_id", users.0._id: Cast to ObjectID failed for value "az" at path "_id", users.0.user.profile.lastName: Path `user.profile.lastName` is required., users.0.user.profile.firstName: Path `user.profile.firstName` is required., users.0.user._id: Path `user._id` is required., users.1.user.profile.lastName: Path `user.profile.lastName` is required., users.1.user.profile.firstName: Path `user.profile.firstName` is

日尔维纳斯

我认为你的GroupSchema定义不正确：

var GroupSchema = 
{
    _id: {
        type: String, 
        required: true
    },
     users:[{
         user: User.userSchema
     }]
};

您在测试users数组中使用它的方式应该具有User.userSchema数组类型：

var GroupSchema = 
{
    _id: {
        type: String, 
        required: true
    },
     users:[{
         type: User.userSchema // type, not 'user'
     }]
     // OR just: users: [User.userSchema]
};

否则，如果您仍然需要使用原始模式，那么在您的测试中您应该这样使用它：

  var users = [
    { user: { _id: 'az', profile: {firstName: 'a', lastName: 'z'}} },
    { user: { _id: 'bz', profile: {firstName: 'b', lastName: 'z'}} },
  ];
