Javascript 将元素推送到Mongoose中的数组，同时保留数组中的所有其他元素

我有以下两个模式:

博客架构:

const blogSchema = new mongoose.Schema(
  {
    title: { type: String, min: 3, max: 20, required: true },
    content: { type: String, required: true },
    likes: { type: Number, required: true, default: 0 },
    author: { type: mongoose.SchemaTypes.ObjectId, ref: "User" },
    comments: [
      { type: mongoose.SchemaTypes.ObjectId, ref: "Comment", default: [] },
    ],
  },
  { timestamps: true, collection: "blogs" }
);

用户架构:

const userSchema = new mongoose.Schema(
  {
    name: { type: String, min: 3, max: 20, required: true },
    email: { type: String, required: true, unique: true },
    password: { type: String, min: 3, max: 50, required: true },
    blogs: [
      {
        type: mongoose.SchemaTypes.ObjectId,
        type: String,
        ref: "Blog",
        required: false,
        default: [],
      },
    ],
    comments: [
      {
        type: mongoose.SchemaTypes.ObjectId,
        type: String,
        ref: "Comment",
        required: false,
        default: [],
      },
    ],
  },
  { timestamps: true, collection: "users" }
);

当我添加一个新博客时，我想要更新用户模式中的博客数组，并向其中添加新的博客ID.我试着这样做:

const { title, content, author } = input;

const newBlog = await Blog.create({
  title: title,
  content: content,
  author: author,
});

let user = await User.findById(author);

await user.updateOne(
  { blogs: [...user.blogs] },
  { $push: { blogs: newBlog } }
);
await user.save();

console.log(newBlog);
return await newBlog.populate("author");

博客被添加到集合中，但用户模型中的数组没有更新. 如果你有什么建议，请让我知道.
