CastError:在路径"userStories“中值"21trt5sdsdesd111521”转换为ObjectId失败

Question

嗨，我正在stackato上安装一个应用程序，我得到了以下错误：

下面是它所引用的代码部分

    var story1 = new userStoryModel ({
        id          : '21trt5sdsdesd111521',
        project     : reg.id,
        title       : 'Moving a US from the Current to Done',
        storyType   : 'Feature',
        points      : '5',
        isEstimated : true,
        requester   : player2.id,
        owner       : player1.id,
        description : 'test test test.',
        task        : []
    });

你知道为什么不能工作吗？

Answer 1

这很可能是因为您的UserStoryModel模式需要一个ObjectID而不是一个字符串作为id。我也不明白为什么它是"id“而不是"_id”，但也许你的特定框架会转换它。

试一试

 var ObjectID = require('mongodb').ObjectID; //your particular framework may have an easier way to access this than requireing mongodb
 var story1 = new userStoryModel ({
        id          : new ObjectID('21trt5sdsdesd111521'),
        project     : reg.id,
        title       : 'Moving a US from the Current to Done',
        storyType   : 'Feature',
        points      : '5',
        isEstimated : true,
        requester   : player2.id,
        owner       : player1.id,
        description : 'test test test.',
        task        : []
    });
