laravel create method

1// If there's a flight from Oakland to San Diego, set the price to $99.
2// If no matching model exists, create one.
3$flight = App\Flight::updateOrCreate(
4    ['departure' => 'Oakland', 'destination' => 'San Diego'],
5    ['price' => 99, 'discounted' => 1]
6);

1# The easiest way to create a model instance is using the 
2# make:model Artisan command:
3
4php artisan make:model Flight
5
6# If you would like to generate a database migration when you 
7# generate the model, you may use the --migration or -m option:
8
9php artisan make:model Flight --migration
10php artisan make:model Flight -m

1// Retrieve flight by name, or create it if it doesn't exist...
2$flight = App\Flight::firstOrCreate(['name' => 'Flight 10']);
3
4// Retrieve flight by name, or create it with the name, delayed, and arrival_time attributes...
5$flight = App\Flight::firstOrCreate(
6    ['name' => 'Flight 10'],
7    ['delayed' => 1, 'arrival_time' => '11:30']
8);
9
10// Retrieve by name, or instantiate...
11$flight = App\Flight::firstOrNew(['name' => 'Flight 10']);
12
13// Retrieve by name, or instantiate with the name, delayed, and arrival_time attributes...
14$flight = App\Flight::firstOrNew(
15    ['name' => 'Flight 10'],
16    ['delayed' => 1, 'arrival_time' => '11:30']
17);

1// If there's a flight from Oakland to San Diego, set the price to $99.
2// If no matching model exists, create one.
3$flight = App\Models\Flight::updateOrCreate(
4    ['departure' => 'Oakland', 'destination' => 'San Diego'],
5    ['price' => 99, 'discounted' => 1]
6);

1firstOrCreate() will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.
2firstOrNew() will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save() on the model). Otherwise it will give you the matched item.

1Alternatively, there's also a create method which accepts a plain PHP array instead of an Eloquent model instance.
2$post = Post::find(1);
3
4$post->comments()->create([
5    'message' => 'This is a new comment message'
6]);
