ember.js - Ember data - send only properties that have values -

i have model many attributes , associations. of them may or may not null. trying ajax call model payload, , properties can null.

i want send properties have values, , not null, including associations.

is possible? kindly let me know if possible.

export default ds.model.extend({       name : ds.attr('string'),       address : ds.hasmany('address')  }); 

for should override serializer. if use default jsonapiserializer right place serializeattribute hook:

export default ds.jsonapiserializer.extend({   serializeattribute(snapshot, json, key) {     if(snapshot.attr(key) != null) {       this._super(...arguments);     }   } }); 

this work attributes, not relationships. same.

you can write own serializer. implement serialize hook, , write code want create json want.
