Node.js 如何设置；“封顶”；创建集合后是否按程序进行集合？

我正在尝试在mongoose.Schema中为我的集合设置一个

capped

参数，该集合最初不包括

capped

。 欢迎任何帮助

我的模式：

    const mongoose = require('mongoose')
    
    var Schema = mongoose.Schema;
    var userSchema = new Schema({
        name:  { type: String, required: true },
        email: { type: String },
        password: { type: String },
        isAdmin: {type: Boolean, default: false},
        avatar: { type: String },
        joinDate: { type: Date, default: Date.now() },
    },{ autoCreate: true, capped : 1024})

userSchema.set('timestamps', true);
const Users = mongoose.model('Users', userSchema)
module.exports = Users;

我发现以下错误：

Error: A non-capped collection exists with the name: users  
To use this collection as a capped collection, please first convert it.

似乎您已经在数据库中创建了一个

users

集合。因此，要将其转换为

mongoshell

或

robomongo

db.runCommand( { convertToCapped: 'users', size: 1024 } )
