Schema validation for string length handling

  • 772

I have the following model inmongoose

import mongos from 'mongoose'
import validator from 'mongoose-unique-validator'

const schema = new mongos.Schema({

    name: { 
        type     : String, 
        required : [ true, 'El nombre del rol es necesario' ],
        unique   : [ true, 'Ya existe un rol con ese nombre' ],
        max      : [ 50, 'El nombre no puede exceder los 50 caracteres' ],
        min      : [ 3, 'El rol debe contener 3 o más caracteres' ]
    },
    status       : { type: String, default: 'active' },
    addedBy      : { type: mongos.Types.ObjectId, ref: 'User' },
    addedDate    : { type: Date, default: Date.now },
    modification : {
        user     : { type: mongos.Types.ObjectId, ref: 'User' },
        date     : { type: Date, default: Date.now },
        current  : { type: String },
        updated  : { type: String }
    }
}, { collection: 'roles' } )


schema.plugin( validator, { message: 'Ya existe {VALUE} en la base de datos' } )

const RoleModel = mongos.model( 'Role', schema )

export default RoleModel

When I start the validations:

  1. passed therequired
  2. passed theunique
  3. Did not pass the max(Makes the insertion)
  4. Did not pass the min(Makes the insertion)

I don't understand what I'm doing wrong, can you help me?

    The problem is that you are using the wrong validation for the type of field you want to validate.

    Mongoose's built -in validations minandmax are validations used for data types Number, and you want to validate data types String.

    The validations you should use for a type Stringare minlengthandmaxlength .

    Your Mongoose schema should look like this:

    import mongos from 'mongoose'
import validator from 'mongoose-unique-validator'

const schema = new mongos.Schema({

    name: { 
        type           : String, 
        required       : [ true, 'El nombre del rol es necesario' ],
        unique         : [ true, 'Ya existe un rol con ese nombre' ],
        maxlength      : [ 50, 'El nombre no puede exceder los 50 caracteres' ],
        minlength      : [ 3, 'El rol debe contener 3 o más caracteres' ]
    },
    status       : { type: String, default: 'active' },
    addedBy      : { type: mongos.Types.ObjectId, ref: 'User' },
    addedDate    : { type: Date, default: Date.now },
    modification : {
        user     : { type: mongos.Types.ObjectId, ref: 'User' },
        date     : { type: Date, default: Date.now },
        current  : { type: String },
        updated  : { type: String }
    }
}, { collection: 'roles' } )


schema.plugin( validator, { message: 'Ya existe {VALUE} en la base de datos' } )

const RoleModel = mongos.model( 'Role', schema )

export default RoleModel

    I hope this clears your doubt.
