推入阵列猫鼬和猫鼬

Question

每当我试图插入嵌套在注释中的likeList数组时，我都会得到以下错误likeList。

在执行下列操作时：

   Feed.findOneAndUpdate(
          {
            owner: req.body.authorId,
            "posts.comments.commentList._id": req.body.commentId
          },
          {
            $push: {
              "posts.$.comments.commentList.likes.likeList": {
                user: req.user._id,
                avatar: req.user.profile.profile_picture.url,
                name: req.user.name
              }
        )

我的模式如下：

馈电模式

 owner: {
    type: Schema.Types.ObjectId,
    ref: "userType"
  },
         posts: [
            {
               author: {
               userType: {
               type: String,
               enum: ["IndustryPartner", "User", "School"]
            },
            user: {
              type: Schema.Types.ObjectId,
              ref: "posts.author.userType", //<- This may cause an issue, if there are any issues with retrieving user fields, CHECK THIS
              required: true
            },
            name: { type: String, required: true },
            avatar: { type: String, required: true }
          },
              comments: {
                totalComments: { type: Number, default: 0 },
                commentList: [
                  {
                    likes: {
                      totalLikes: { type: Number, default: 0 },
                      likeList: [ <---//Trying to push here
                        {
                          user: { type: Schema.Types.ObjectId, ref: "User" },
                          avatar: { type: String },
                          name: { type: String },
                          date: {
                            type: Date,
                            default: Date.now
                          }
                        }
                      ]
                    ...

我不确定这是否是我在第一个用于筛选的参数中使用的查询的问题。

更新整个错误消息这是奇怪的，因为它看起来实际上正在找到正确的commentList，但无法访问数组本身中的commentList字段。我是否错了，假设这应该能够通过它？posts.$.comments.commentList.likes.likeList

      { MongoError: Cannot create field 'likes' in element {commentList: [ { likes: { totalLikes: 0, likeList: [] }, 
_id: ObjectId('5cf6b3293b61fe06f48794e3'), user: ObjectId('5c9bf6eb1da18b038ca660b8'), avatar: "https://sli.blob.core.windows.net/stuli/
profile-picture-e1367a7a-41c2-4ab4-9cb5-621d2008260f.jpg", name: "Luke Skywalker", text: "Test comment from Luke", repliesToComment: [], date: new Date(1559671593009) } ]}

经过进一步的研究，经过两个层次的数组后，位置算子似乎不再有用。因此，解决方案是使用JS更改将值推送到数组中，然后保存它们。
