Question

我有一个用户和个人资料对象。在用户对象中，它内部有一个名为profile的数组变量（它应该通过ID号作为参考来存储配置文件对象）。它们都是分别成功创建的，但是当我尝试通过用户ID将配置文件添加到用户中并在mongodb控制台上对其进行搜索时，它会显示为空。

代码的相关部分：

var UserSchema = new mongoose.Schema({
   username: String,
   password: String,
   hasProfile: Boolean,
   profile: [
   {
    type: mongoose.Schema.Types.ObjectId,
    ref: "Profile"
   }
   ]
});

================================================ ===================

var ProfileSchema = new mongoose.Schema({
   name: String,
   location: String,
   profilePic: String,
   photoAlbum: {image: String},
   statusUpdates: {image: String},
   newsFeed: {image: String}
});

================================================ =========

app.post("/socialNetwork/createProfile", isLoggedIn, function(req,res){
    var currUser = req.user;
    var currUserId = req.user.id;
    var currProfile = req.body.profile;

    Profile.create({
       name: currProfile.name,
       location: currProfile.location
    });

    curUser.profile.push(currProfile.id);
    currUser.save();
});

我认为您必须采用最近创建的配置文件的_id，然后将其推入用户的配置文件数组中，此_id由mongodb创建，与let str2 = str1.replacingOccurrences(of: "\\", with: "")中的内容不同

因此您可以添加一个回调函数来创建新的配置文件操作，然后从中获取添加的配置文件的_id

currProfile.id

请注意，您在将profile._id推送到个人档案数组时使用app.post("/socialNetwork/createProfile", isLoggedIn, function(req, res) { var currUser = req.user; var currUserId = req.user.id; var currProfile = req.body.profile; Profile.create({ name: currProfile.name, location: currProfile.location }, function(err, newProfile) { if (err) { // handle error } else { // here we can take the _id from the newProfile and add it to the user currUser.profile = currUser.profile || []; // double check the profile array, as if this is the first time to push an item to it currUser.profile.push(newProfile._id); currUser.save(); } }); });而不是curUser
