如何在Laravel中同时保存两个模型

Question

我想知道如何保存在我的模型中有一个关系的两个模型。我不知道如何保存，但我需要将患者模型的ID分配给我的比例模型。

这是我的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.');
}

我尝试了这个代码，但出现了错误。

DB::transaction(function() use ($patient, $scales) {
$patient = $patient->save(); //Patient Exists First
Patient::find($patient->id)->scales()->save($scales)
});

你可以试试这样的东西：

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.');
}

如果模型像您所说的那样使用hasOne()关系，那么代码就会显示工作，当然需要进行一些修改。

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 = 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.');
}

首先创建并存储基本模型，并引用它保存相关模型

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.');
}
