Answers for "laravel update attribute"

laravel updateOrCreate

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

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 -m

laravel add attribute to model

//The problem is caused by the fact that the Model's toArray() method ignores any accessors which do not directly relate to a column in the underlying table.

//As Taylor Otwell mentioned here, "This is intentional and for performance reasons." However there is an easy way to achieve this:

class EventSession extends Eloquent {

    protected $table = 'sessions';
    protected $appends = array('availability');

    public function getAvailabilityAttribute()
    {
        return $this->calculateAvailability();  
    }
}

laravel model set new attribute

public function getAvailabilityAttribute()
    {
        return $this->calculateAvailability();  
    }
