How can I save two models at the same time in Laravel? - php

Question

I want to know how can I save two models which has one relationship in my models. I don't know how to save it but I need the ID for my patient model to assign to my scale model.
Here is my PatientController.
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required',
'birth' => 'required',
'nacionality' => 'required',
'adress' => 'required',
'phone' => 'required',
'living_method' => 'required',
'responsable' => 'required',
]);
//Create Patient
$patient = new Patient;
$scales = new Scale;
$patient->name = $request->input('name');
$scales->sd_abc_1_old = $request->input('sd_abc_1_old');
$patient->save();
return redirect('/patients')->with('success', 'Paciente creado.');
}
I try this code but get error.
DB::transaction(function() use ($patient, $scales) {
$patient = $patient->save(); //Patient Exists First
Patient::find($patient->id)->scales()->save($scales)
});

You could try something like this:
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required',
'birth' => 'required',
'nacionality' => 'required',
'adress' => 'required',
'phone' => 'required',
'living_method' => 'required',
'responsable' => 'required',
]);
//Create Patient
$patient = new Patient;
$patient->name = $request->name;
$patient->save();
$patient->scale()->create(['patient_id' => $patient->id, 'sd_abc_1_old' => $request->sd_abc_1_old]);
);
return redirect('/patients')->with('success', 'Paciente creado.');
}
If the model uses a hasOne() relation like you said then the code show work, with a bit of modification of course.

'name' => 'required',
'birth' => 'required',
'nacionality' => 'required',
'adress' => 'required',
'phone' => 'required',
'living_method' => 'required',
'responsable' => 'required',
]);
//Create Patient
$patient = Patient::create([
'name' => $request->input('name'),
]);
$scale = Scale::create([
'patient_id' => $patient->id,
'sd_abc_1_old' => $request->sd_abc_1_old,
]);
return redirect('/patients')->with('success', 'Paciente creado.');
}

First create and store base model and referencing it save related model
public function store(Request $request)
{
$this->validate($request, [
'name' => 'required',
'birth' => 'required',
'nacionality' => 'required',
'adress' => 'required',
'phone' => 'required',
'living_method' => 'required',
'responsable' => 'required',
]);
//Create Patient
$patient = new Patient;
$patient->name = $request->input('name');
$patient->save();
$scales = new Scale;
$scales->sd_abc_1_old = $request->input('sd_abc_1_old');
$patient->scales()->save($scales);
return redirect('/patients')->with('success', 'Paciente creado.');
}
