hola, estoy haciendo modelos para mi mongodb, y al validar quiero que se requiera el cumpleaños solo si el usuario que se agrega es un estudiante, así que si el usuario es un maestro, está bien si no se proporciona un cumpleaños
const userSchema = mongoose.Schema({ 20 21 _id: mongoose.Schema.Types.ObjectId, 22 23 firstName: { 24 type: String, 25 required: [true, 'the firstName is missing'], 26 validate: [(val) => validator.isAlpha(val, ['fr-FR']), 'not valid first name'], 27 }, 28 lastName: { 29 type: String, 30 required: [true, 'the lastName is missing'], 31 validate: [(val) => validator.isAlpha(val, ['fr-FR']), 'not valid last name'], 32 }, 33 birthday: { 34 type: Number, 35 required: [true, 'birthday is missing'] 36 validate: [(val) => 37 phoneNumber: { 38 type: String, 39 required: [true, 'the phoneNumber is missing'], 40 unique: [true, 'phoneNumber already in use'], 41 validate: [(val) => validator.isMobilePhone(val,['ar-DZ']), 'not valid phone number'], 42 }, 43 email : { 44 type: String, 45 required: [true, 'the email is missing'], 46 unique: [true, 'email already in use'], 47 validate: [validator.isEmail, 'not valid email'], 48 }, 49 password: { 50 type: String, 51 required: [true, 'the password is missing'], 52 minlength: [10, 'error when generating a password for the user'], 53 }, 54 role: { 55 type : String, 56 "enum" : ['teacher', 'student'], 57 required : [true, 'the user `s role is missing'], 58 },La propiedad required también puede aceptar una función . Por ejemplo:
required: [ function () { return this.role === 'student'; }, 'birthday is missing' ]Puede crear una función para validar el valor del role y utilizarlo como un valor booleano en la propiedad required .
const mongoose = require('mongoose'); const Schema = mongoose.Schema; var userSchema = new Schema({ _id: mongoose.Schema.Types.ObjectId, firstName: { type: String, required: [true, 'the firstName is missing'], validate: [(val) => validator.isAlpha(val, ['fr-FR']), 'not valid first name'], }, role: { type: String, enum: ['teacher', 'student'], required: [true, 'the user `s role is missing'], }, birthday: { type: Number, required: [isBirthdayRequired, 'the birthday is missing'] }, }); function isBirthdayRequired() { if (this.role === 'student') { return true; } return false; }
