laravel create model
# The easiest way to create a model instance is using the
# make:model Artisan command:
php artisan make:model Flight
# If you would like to generate a database migration when you
# generate the model, you may use the --migration or -m option:
php artisan make:model Flight --migration
php artisan make:model Flight -mlaravel firstorcreate
// Retrieve flight by name, or create it if it doesn't exist...
$flight = App\Flight::firstOrCreate(['name' => 'Flight 10']);
// Retrieve flight by name, or create it with the name, delayed, and arrival_time attributes...
$flight = App\Flight::firstOrCreate(
['name' => 'Flight 10'],
['delayed' => 1, 'arrival_time' => '11:30']
);
// Retrieve by name, or instantiate...
$flight = App\Flight::firstOrNew(['name' => 'Flight 10']);
// Retrieve by name, or instantiate with the name, delayed, and arrival_time attributes...
$flight = App\Flight::firstOrNew(
['name' => 'Flight 10'],
['delayed' => 1, 'arrival_time' => '11:30']
);laravel model::query
// Eloquent's Model::query() returns the query builder
Model::where()->get();
// Is the same as
Model::query()->where()->get();
Model::query();
// Can be useful to add query conditions based on certain requirements
