node.js - sails.js nested models -

in sails.js 0.10 i'm trying following

// user.js module.exports = {   attributes: {      uuid: {         type: 'string',         primarykey: true,         required: true      } ,      profile: {          firstname: 'string',         lastname: 'string',         birthdate: 'date',         required: true      }   } }; 

i'm getting error when trying create user , sailsjs doesn't recognize "profile" attribute. i'm not sure if sails supports nested json structure, , if i'm not sure how structure it.

error: sent 500 ("server error") response error: error: unknown rule: firstname 

i've tried following failed too

// user.js module.exports = {   attributes: {      uuid: {         type: 'string',         primarykey: true,         required: true      } ,      profile: {          firstname: {type: 'string'},         lastname: {type: 'string'},         birthdate: 'date',         required: true      }   } }; 

i know there attribute called "json" sailsjs 0.10, not sure how fit module.

waterline doesn't support defining nested schemas, can use json type store embedded objects in model. so, do:

profile: {     type: 'json',     required: true } 

and create user instances like:

user.create({profile: {firstname: 'john', lastname: 'doe'}}) 

the difference firstname , lastname fields won't validated. if want validate schema of embedded profile object matches want, you'll have implement beforevalidate() lifecycle callback in model class:

attributes: {}, beforevalidate: function(values, cb) {     // if profile being saved user...     if (values.profile) {        // validate values.profile data matches desired schema,        // , if not call cb('profile no good');        // otherwise call cb();     } }
