Question

我正在尝试为用户添加评论API。我定义了一个不同的模型架构'userMessages'，并使用userId作为架构'User'的引用。我试图发布路由进行评论，但收到验证错误，即使我已将userId和Comment String定义为true。

这是我的userMessages模式：

const userMessages = mongoose.Schema({
_id: mongoose.Schema.Types.ObjectId,
userId: { type: mongoose.Schema.Types.ObjectId, ref: 'User', required: true},
message: { type: String, required: true },

});

这是我添加消息的控制器：

exports.post_comment = (req, res, next) => {

let body = req.body;
body._id = mongoose.Types.ObjectId();

const userId = req.userData.user[0]._id;
body.userId = userId._id;

const commentSchema = new CommentSchema(body);

commentSchema.save()
    .then(docs => {
        console.log('user commented: ', docs);
        res.status(201).json(docs);
    })
    .catch(err => {
        console.log(err);
        res.status(500).json(err);
    })

}

当我尝试使用邮递员以“ userId和message”作为原始参数来打路由userMsg / comment时，出现以下错误：

{
"errors": {
    "userId": {
        "message": "Path `userId` is required.",
        "name": "ValidatorError",
        "properties": {
            "message": "Path `userId` is required.",
            "type": "required",
            "path": "userId"
        },
        "kind": "required",
        "path": "userId"
    }
},
"_message": "UserMessages validation failed",
"message": "UserMessages validation failed: userId: Path `userId` is required.",
"name": "ValidationError"
}

即使将userID和message定义为TRUE，我也无法解决问题。

错误在以下几行：

const userId = req.userData.user[0]._id;
body.userId = userId._id;

应该是：

const userId = req.userData.user[0]._id;
body.userId = userId;

修复节点js中已定义架构的验证错误
