I have complex object Model, with composition of other objects, and I use JsonSerializable in each of them.
Let take simplified example:
class CarPark implements JsonSerializable
{
/** @var array|Car[] */
private array $cars;
...
public function jsonSerialize()
{
return [
"title" => "My cars",
"cars" => $this->cars
];
}
}
class Car implements JsonSerializable
{
private string $model;
private string $year;
...
public function jsonSerialize()
{
return [
"model" => $this->model,
"year" => $this->year,
"price" => $this->calculate()
];
}
private function calculate():string {
...
}
}
For API I just do return new JsonResponse($carPark); and get nice json.
I want to save this object in DB as json, but I dont want to save 'price' value.
My question is:
How to make my object for API pass one json structure and for db another json structure?
P.S. For Laravel DB ORM I use Doctrine.
My Answer:
'cars' => $this->cars, ]; }}
class Car implements JsonSerializable{
/** @var string */
private string $brand;
/** @var string */
private string $model;
public function jsonSerialize()
{
return [
'brand' => $this->brand,
'model' => $this->model,
];
}
}
In this example, the CarPark class has an array of Car objects. Each Car object implements the JsonSerializable interface to customize how it is serialized to JSON. When you serialize a CarPark object, it will also serialize the array of Car objects inside it according to the jsonSerialize method defined in the Car class.
