Laravel if id exist then update record - ajax

Question

i want to set condition, if teacher already exist in database then update record, if id doesn't exist then add record in database. how can i achieve it using ajax in laravel?
Update.js:
jQuery(document).ready(function($) {
$('#update-data').on('click',function(){
alert("ok");
$.ajax({
type: "POST",
url: "teachers/" + $('#update-data').attr("value"),
dataType: 'json',
headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') },
data : $(this).serialize(),
beforeSend: function() {
},
success: function (data) {
alert("ok");
},
});
});
});
Store.Js:
jQuery(document).ready(function($) {
$("#add-data").submit(function (e) {
$.ajax({
type: "POST",
url: "teachers",
dataType: 'json',
headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') },
data: $(this).serialize(),
success: function (data) {
alert("Added");
data.responseJSON;
refreshTable();
},
});
});
});
Update Controller:
public function update(TeacherRequest $request, $id)
{
$teacher = Teacher::find($id);
if($teacher->save()){
return response()->json([
'status' => 'success',
'msg' => 'esecond has been updated'
]);
}
}
Store Controller:
public function store(Request $request)
{
$teacher = new Teacher;
$teacher=teacher::create($request);
}

Answer 1

There's a custom method for this
$teacher = Teacher::firstOrCreate($id, [
// Pass data here
]);
And if you want to check manually and traverse the request to another method
public function update(TeacherRequest $request, $id)
{
$teacher = Teacher::find($id);
if (is_null($teacher)) { // If model not found, pass request to store method
$this->store($request);
}
if($teacher->save()){
return response()->json([
'status' => 'success',
'msg' => 'esecond has been updated'
]);
}
}
From the docs
Hope this helps

Eloquent provides a updateOrCreate method so you can update or create a record.
$teacher = Teacher::updateOrCreate([
// attributes to search for
'name' => 'Test Teacher',
], [
// values
'grade' => 6,
]);
This would find a teacher with name 'Test Teacher' and update grade to 6 or create a new teacher with name 'Test Teacher' and grade set to 6.
"You may also come across situations where you want to update an existing model or create a new model if none exists. Laravel provides an updateOrCreate method to do this in one step. Like the firstOrCreate method, updateOrCreate persists the model ..." - Laravel 6.0 Docs - Eloquent - Other Creation Methods - updateOrCreate
