Class JSONSerializer

attrs

Defined in ../serializer/addon/json.js:107

The attrs object can be used to declare a simple mapping between property names on Model records and payload keys in the serialized JSON object representing the record. An object with the property key can also be used to designate the attribute's key on the response payload.

Example

import Model, { attr } from '@ember-data/model';

export default class PersonModel extends Model {
  @attr('string') firstName;
  @attr('string') lastName;
  @attr('string') occupation;
  @attr('boolean') admin;
}

import JSONSerializer from '@ember-data/serializer/json';

export default class PersonSerializer extends JSONSerializer {
  attrs = {
    admin: 'is_admin',
    occupation: { key: 'career' }
  }
}

You can also remove attributes and relationships by setting the serialize key to false in your mapping object.

Example

import JSONSerializer from '@ember-data/serializer/json';

export default class PostSerializer extends JSONSerializer {
  attrs = {
    admin: { serialize: false },
    occupation: { key: 'career' }
  }
}

When serialized:

{
  "firstName": "Harry",
  "lastName": "Houdini",
  "career": "magician"
}

Note that the admin is now not included in the payload.

Setting serialize to true enforces serialization for hasMany relationships even if it's neither a many-to-many nor many-to-none relationship.

primaryKey

Defined in ../serializer/addon/json.js:83

The primaryKey is used when serializing and deserializing data. Ember Data always uses the id property to store the id of the record. The external source may not always follow this convention. In these cases it is useful to override the primaryKey property to match the primaryKey of your external store.

Example

import JSONSerializer from '@ember-data/serializer/json';

export default class ApplicationSerializer extends JSONSerializer {
  primaryKey = '_id'
}

store public

Inherited from Serializer ../serializer/addon/index.js:27

The store property is the application's store that contains all records. It can be used to look up serializers for other model types that may be nested inside the payload response.

Example:

Serializer.extend({
  extractRelationship(relationshipModelName, relationshipHash) {
    let modelClass = this.store.modelFor(relationshipModelName);
    let relationshipSerializer = this.store.serializerFor(relationshipModelName);
    return relationshipSerializer.normalize(modelClass, relationshipHash);
  }
});
