【问题描述】：

所以我尝试了这个问题的上一个解决方案 1滴收集 2-drop数据库 3-添加dropDups 没有任何效果

const userSchema = new Schema(
    name: 
        type: String,
        required: [true, "please Enter your Name"],
        lowercase: true,
    ,
    username: 
        type: String,
        required: [true, "please Enter your user name"],
        index:  unique: true, dropDups: true ,
    ,
    email: 
        type: String,
        required: [true, "please Enter your Email"],
        unique: true,
        lowercase: true,
        validate: [isEmail, "please Enter a valid Email"],
    ,
    password: 
        type: String,
        required: [true, "please Enter a Password"],
        minlength: [8, "minimum password length is 8 characters"],
    ,
    address: 
        type: String,
        required: [true, "please Enter your address"],
    ,
);


module.exports = User = mongoose.model("user", userSchema);

如果有人有更新的解决方案，那就太好了

【参考方案1】：

您使用什么来添加新用户？ 我有同样的问题，我正在使用 User.create(...) 而是使用 new User (...)

async addUser(req, res) 
        const  name, username, email, password, address  = req.body;
        try 
            const user = new User(
                name: name,
                username: username,
                email: email,
                password: password,
                address: address,
            );
            const data = await user.save();
            res.status(201).json(data);
         catch (err) 
            
            res.status(400).send(err);
