如何检查记录是否已经存在，然后在laravel中更新或插入？

Question

I am trying to check first if data is already exists or not ,if data is already exists ,then update function otherwise insert a new record. Its working when inserting a new record, but i don't want to be duplicate rows in future,

  public function store(Request $request) { $requestData = $request->all(); $jobseeker = new Jobseeker(); $jobseeker->fullname= $requestData['full name']; $jobseeker->gender= $requestData['Gender']; $jobseeker->messenger_user_id= $request->{'messenger user id'}; $jobseeker->save(); } 

So here is how i tried, i check the messenger user id is already exists or not,if messenger user id already exists i want to update the existing row,otherwise i want to insert a new row.

  public function store(Request $request,$messenger_user_id) { $requestData = $request->all(); $my_msg_id = Jobseeker::where('messenger_user_id',$requestData['messenger user id'])->first(); if (is_null($my_msg_id)) { $jobseekers = Jobseeker::find($messenger_user_id); $jobseeker->fullname= $requestData['full name']; $jobseeker->gender= $requestData['Gender']; $jobseeker->messenger_user_id= $request->{'messenger user id'}; } else{ $jobseeker = new Jobseeker(); $jobseeker->fullname= $requestData['full name']; $jobseeker->gender= $requestData['Gender']; $jobseeker->messenger_user_id= $request->{'messenger user id'}; $jobseeker->save(); } } 

Can someone guide me, thanks in advanced.

You don't need to do all of this yourself in laravel. Use the method firstOrCreate .

$data_array = [
    'full_name' => $requestData['full name'],
    'gender' => $requestData['Gender'],
];

$jobseeker = App\Jobseeker::firstOrCreate(['messenger_user_id' => $messenger_user_id], $data_array);

It takes an array as first parameter to find a model and array as a second parameter to update the record with given key-values in that array or it'll create a new record with given data, then returns the model object.
