Laravel访问被拒绝将模型存储到数据库中

I want to send my model into database via ajax in Laravel.

Here is my ajax call

    $('.btn-like').click(function(event) {
        $.ajax({
        url: 'like',
        type: 'POST'
        })
        .done(function(data) {
            console.log(data);
        }); 

    });

And here is my route

Route::post('like', [
    'uses' => 'DefaultController@like'
]);

and Here Like function in the DefaultController controller

public function like()
{
    $like = new Like();
    $like->save();
}

And here hte Like model

class Like extends Eloquent {

    protected $table = 'likes';

}

And this is error what I get

Access denied for user 'homestead'@'localhost' (using password: YES)"

btw. here is how I set my env

$env = $app->detectEnvironment(array(

    'local' => array('Itachi'),

));

does anyone know where can be problem?

Thank you very much for any advice.

Your defined database credentials within app/config/database.php are wrong.

Please make sure your database settings are correct. Also check if provided user homestead has permissions for selected database.
