用猫鼬验证整数值 [英] Validate integer values with mongoose

问题描述

我正在使用猫鼬，我需要定义如下所示的架构:

I'm using mongoose and I need to define a schema like the following:

const QuestionSchema = new Schema({
    text: {
        type: String,
        required: true
    },
    number: {
        type: Number,
        required: true,
        unique: true
    }
});

我需要验证number字段是一个整数值.我已经看到了几个插件，例如: mongoose-integer :

I need to validate that the number field is an integer value. I have seen a couple plugins for that, e.g: mongoose-integer:

const validateInteger = require('mongoose-integer');
const QuestionSchema = new Schema({
    text: {
        type: String,
        required: true
    },
    number: {
        type: Number,
        required: true,
        unique: true,
        integer: true
    }
});
QuestionSchema.plugin(validateInteger);

但是我不希望使用任何第三方库.还有其他办法吗?预先感谢.

But I'd prefer not using any third party libraries. Is there any other way? Thanks in advance.

推荐答案

您可以添加 number的自定义验证器:

You can add a custom validator for number:

number: {
  type     : Number,
  required : true,
  unique   : true,
  validate : {
    validator : Number.isInteger,
    message   : '{VALUE} is not an integer value'
  }
}
