Class Serializer

The normalize method is used to convert a payload received from your external data source into the normalized form store.push() expects. You should override this method, munge the hash and return the normalized payload.

Example:

Serializer.extend({
  normalize(modelClass, resourceHash) {
    let data = {
      id:            resourceHash.id,
      type:          modelClass.modelName,
      attributes:    resourceHash
    };
    return { data: data };
  }
})

The normalizeResponse method is used to normalize a payload from the server to a JSON-API Document.

Example:

Serializer.extend({
  normalizeResponse(store, primaryModelClass, payload, id, requestType) {
    if (requestType === 'findRecord') {
      return this.normalize(primaryModelClass, payload);
    } else {
      return payload.reduce(function(documentHash, item) {
        let { data, included } = this.normalize(primaryModelClass, item);
        documentHash.included.push(...included);
        documentHash.data.push(data);
        return documentHash;
      }, { data: [], included: [] })
    }
  }
});

The serialize method is used when a record is saved in order to convert the record into the form that your external data source expects.

serialize takes an optional options hash with a single option:

• includeId: If this is true, serialize should include the ID in the serialized object it builds.

Example:

Serializer.extend({
  serialize(snapshot, options) {
    let json = {
      id: snapshot.id
    };

    snapshot.eachAttribute((key, attribute) => {
      json[key] = snapshot.attr(key);
    });

    snapshot.eachRelationship((key, relationship) => {
      if (relationship.kind === 'belongsTo') {
        json[key] = snapshot.belongsTo(key, { id: true });
      } else if (relationship.kind === 'hasMany') {
        json[key] = snapshot.hasMany(key, { ids: true });
      }
    });

    return json;
  },
});
