Save vs update in laravel

Question

What is the difference between save() and update() method in Laravel.

I have used save() method in case of update query but in few cases it acts as update and in few case it act as insert query function. Please let me know what exactly the difference between them.

Answer 1

These methods both allow you to save data to a database.

The save() method performs an INSERT when you create a new model which is currently is not present in your database table:

 $flight = new Flight;

 $flight->name = $request->name;

 $flight->save(); // it will INSERT a new record

Also it can act like an UPDATE, when your model already exists in the database. So you can get the model, modify some properties and then save() it, actually performing db's UDPATE:

$flight = AppFlight::find(1);

$flight->name = 'New Flight Name';

$flight->save(); //this will UPDATE the record with id=1

Theupdate() method allows you to update your models in more convenient way:

AppFlight::where('active', 1)
          ->where('destination', 'San Diego')
          ->update(['delayed' => 1]); // this will also update the record

So you don't even need to assign the retrieved model to any variable. Updated properties are passed as arguments.

Examples and more info in the Laravel's docs.
