, и часть JSON дает мне это ..
[{"id":1,"libelle_metier":"metier 1","deleted_at":null,"created_at":"2018-04-03 09:12:37","updated_at":"2018-04-03 09:12:37"},{"id":2,"libelle_metier":"metier 2","deleted_at":null,"created_at":"2018-04-03 09:12:44","updated_at":"2018-04-03 09:12:44"},{"id":3,"libelle_metier":"metier 4","deleted_at":null,"created_at":"2018-04-03 09:46:36","updated_at":"2018-04-04 14:15:06"}]
и мой код PHP и
class TechniciensController extends Controller
{
public function GetTechniciens()
{
return Technicien::all();
}
