Laravel: How to get the first row that matches some where queries, or create it if it doesn't exist (in Laravel's Eloquent)?

You can use the very useful firstOrCreate() to try and find a row, and create it if it doesn't exist.

  1. // Retrieve flight by name, or create it if it doesn't exist...
  2. $flight = App\Flight::firstOrCreate(['name' => 'Flight 10']);
  3.  
  4. // Retrieve flight by name, or create it with the name and delayed attributes...
  5. $flight = App\Flight::firstOrCreate(
  6.     ['name' => 'Flight 10'], ['delayed' => 1]
  7. );
  8.  
  9. // Retrieve by name, or instantiate...
  10. $flight = App\Flight::firstOrNew(['name' => 'Flight 10']);
  11.  
  12. // Retrieve by name, or instantiate with the name and delayed attributes...
  13. $flight = App\Flight::firstOrNew(
  14.     ['name' => 'Flight 10'], ['delayed' => 1]
  15. );

There is also the firstOrNew which works in the same way, however it will provide an unsaved object (i.e. you will have the model object returned from the method call, but it won't be saved in the DB). There is also the updateOrCreate if you need to update models, or create it if none exist.
