Laravel：获取模型类中的当前对象

Question

I'm wondering if it's possible to access the current object when accessing a method of that object. for example the method fullname() below is used to get the full name of the user.

class User extends Eloquent 
{

    public function itineraries() {
        return $this->has_many('Itinerary', 'user_id');
    }

    public function reviews() {
        return $this->has_many('Placereview', 'user_id');
    }

    public function count_guides($user_id){
        return Itinerary::where_user_id($user_id)->count();
    }

    public static function fullname() {
        return $this->first_name . ' ' . $this->last_name; // using $this as an example
    }
}

A user has a first_name field and a last_name field. Is there anyway I can do

$user = User::where('username', '=', $username)->first();

echo $user->fullname();

Without having to pass in the user object?

You're almost there, you just need to remove the static from your code. Static methods operate on a class, not an object; so $this does not exist in static methods

public function fullname() {
    return $this->first_name . ' ' . $this->last_name;
}
