DS.RESTSerializer#keyForPolymorphicType()

keyForPolymorphicType can be used to define a custom key when serializing and deserializing a polymorphic type. By default, the returned key is ${key}Type.

Example

 import DS from 'ember-data';

 export default DS.RESTSerializer.extend({
   keyForPolymorphicType: function(key, relationship) {
     var relationshipKey = this.keyForRelationship(key);

     return 'type-' + relationshipKey;
   }
 });
