 When building APIs using TinyORM, you will often need to convert your models and relationships to vectors, maps, or JSON. TinyORM includes convenient methods for making these conversions, as well as controlling which attributes are included in the serialized representation of your models.

+### Serializing To JSON
 
 To convert a model to JSON, you should use the `toJson` method. Like `toVector` or `toMap`, the `toJson` method is recursive, so all attributes and relations will be converted to JSON. You may also specify any JSON encoding options that are supported by [QJsonDocument::toJson](https://doc.qt.io/qt-6/qjsondocument.html#toJson):

 When a TinyORM model is converted to JSON, its loaded relationships will automatically be included as attributes on the JSON object. Also, though TinyORM relationship methods are defined using "camelCase" method names, a relationship's JSON attributes will be "snake_case".
