我正在编写一个使用javascript，node，mongoDB和mongoose的小应用程序。我有两个集合;用户和组，其中每个组包含用户用嵌套对象编写测试时Mogoose验证错误

用户的数组：{_ ID：{类型：字符串，必需：真}姓：{类型：字符串，必需：真}，..}

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

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

您能否让我知道这个例子出了什么问题？

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(); 
    }); 
    }); 
    }); 
});

错误消息：

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

回答：

我觉得你GroupSchema定义是不正确的：

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

你使用它在测试users阵列应该有User.userSchema数组类型的方法：

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

否则，如果你仍然需要使用你原来的模式，那么在您的测试，你应该使用这种方式：

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