Mongoose需要基于另一个字段的某些枚举值的字段

Question

我有一个Mongoose架构Employee.在此我想存储与办公室员工的字段(电话号码),只有当他/她可享有办公室,里面只有两个层次"高级"和"C级".

架构:

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
var EmployeeSchema = new Schema({
    name: String,
    designation: String,
    level: {type: String, enum: ["intern", "junior", "mid-level", "senior", "c-level"], required: true},
    phoneNo: {type: String, required: true},
    officePhoneNo: {type: String, required: true}   // how to require only if the level is senior or c-level?,

});

感谢您的帮助.

谢谢

在Mongoose中,您可以传递一个函数,required该函数可以true/false根据某些条件返回.

在您的情况下required,也可以依赖于其他字段的字段level.也就是说,您可以选择需要一个字段.这是如何做:

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const levels = ["intern", "junior", "mid-level", "senior", "c-level"];
const levelsEligibleForOffice = ["senior", "c-level"];

var EmployeeSchema = new Schema({
    name: String,
    designation: String,
    level: {type: String, enum: levels, required: true},
    phoneNo: {type: String, required: true},
    officePhoneNo: {type: String, required: isEligibleForOffice}
});


function isEligibleForOffice(){
    if(levelsEligibleForOffice.indexOf(this.level) > -1){  //"this" contains the employee document at the time of required validation
        return true;
    }
    return false;
}
