node.js - 使用 Mongoose 将项目推送到对象中的数组

Question

我想更新数据对象中的 posts 数组。我的架构在这里不起作用:

const mongoose = require('mongoose');
const Post = require('./post');
const Review = require('./comment')

    const User = mongoose.Schema({
        _id: mongoose.Schema.Types.ObjectId,

        username: {
            type: String,
            required: true
        }

        // necessary details needed for the user to initially working with
        data: {

            posts: [
                Post
            ],
            following: [String]
            }
        }

    });

我已经尝试过:

User.update({_id: user}, {data:{$push: {posts: post
  }}}).then(data=>{
    console.log(data);
  })

但它不起作用。谢谢。

试试这个代码:

User.update(
    { "_id": user },
    {
        "$push":
            {
                "data.posts": post
            }
    }
).then(data => {
    console.log(data);
})
