What is the core codes of Laravel Eloquent behind the ->save() method to choose create or edit a new record in database

I understand Laravel is checking the object reference id to check if the object existed, so the save() method will run the edit method to edit it. and if it's a new object, it will run the create() method.

but I can't find the codes behind it, in the Eloquent package.

I want the exact address of the file that includes these codes

from the blow codes I infer the above conclusion:

I wrote this code in Laravel:

$setting = new Setting;
$setting->name = 'name1';
$setting->save();

$setting->name = 'name2';
$setting->save();

after executing I see just name2 in the database and it seems, after saving name1 Laravel edit that and save name2 in the database.

and after I execute this code:

$setting = new Setting;
$setting->name = 'name1';
$setting->save();
$setting = new Setting;
$setting->name = 'name2';
$setting->save();

and I saw both the records saved correctly, so I have name1 and name2.

You can find the code for Eloquent's save() method in vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php on line 833 in Laravel 8.12.

The behaviour that you're observing is a characteristic of the Active Record pattern, which Laravel is based on. Each time you use new to create an Eloquent model, it's creating a object that will represent a row in your database. Within Eloquent's save() method, it will check to see if a record already exists, and if it does it will update it (code below).

if ($this->exists) {
    $saved = $this->isDirty() ?
                $this->performUpdate($query) : true;
}

Your code is working as expected.
