Question

我正在用猫鼬编写用户模式条目的验证。我想在架构中创建两个必需的条目（密码，googleId）中的任何一个，但并非两个条目都是必需的。我想确保该用户具有密码或googleId。如何做到这一点？以下是我的架构

const UserSchema = new mongoose.Schema({
    password: {
        type: String,
        trim: true,
        required: true,
        validate: (value)=>
        {
            if(value.includes(this.uname))
            {
                throw new Error("Password must not contain username")
            }
        }
    },
    googleId: {
        type: String,
        required: true
    }
});

Answer 1

您可能要做的是添加一个预验证检查，然后调用下一个或使文档无效。

const schema = new mongoose.Schema({
    password: {
        type: String,
        trim: true
    },
    googleId: {
        type: String
    }
});

schema.pre('validate', { document: true }, function(next){
    if (!this.password || !this.googleId)
        this.invalidate('passwordgoogleId'. 'One of the fields required.');
    else
        next();
});

我还没尝试过。

您可以使用custom validator：

LOAD DATA LOCAL INFILE 'C:/Users/TEMP/Desktop/tempname.csv' INTO TABLE tempname
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '\\' LINES TERMINATED BY '\n'
(Name, ID, Birthday)

或使用const UserSchema = new mongoose.Schema({ password: { type: String, trim: true, required: true, validate: { validator: checkCredentials, message: props => `${props.value} is not a valid phone number!` }, }, googleId: { type: String, required: true } }); function checkCredentials(value) { if (!this.password || !this.googleId) { return false; } return true; }验证中间件
