node.js - How to validate a model in sailsjs -

i'm using sails , have created model, , of attributes required, if post json of attributes missing still create record in db. i'm using sails-postgresql. i've tried doing manually with:

modelname.create(req.body).done(function(){}) 

you need add special fields models attributes - "required: true" or "minlength: 5"

module.exports = {   attributes: {     name: {       type: 'string',       maxlength: 20,       minlength: 5     },      email: {       type: 'email',       required: true     }   } }
