问题 If I try declaring a property, like this: public $quantity = 9; ...it doesn't work, because it is not considered an "attribute", but merely a property of the model class. Not only this, but also I am blocking access to the actually real and existent "quantity" attribute. What should I do, then? 回答1: An update to this... @j-bruni submitted a proposal and Laravel 4.0.x is now supporting using the following: protected $attributes = array( 'subject' => 'A Post' ); Which will automatically set
