Accesor not available in JSON response

Hi everybody, yesterday I discovered accesors thanks to the community:

https://laracasts.com/discuss/channels/general-discussion/attach-property-to-eloquent-model

They appear to be really handy computed properties for my backend models HOWEVER, I just noticed that they are not retained in the response. That is, on my vue components I don't have access to these properties, they aren't just there. This is SUCH a bummer...

So my question is, how can I make the accessors be retained in the JSON response so I can use these in my views!

So I can use discount.stockLeft in my vue components.

My accessor example:

public function getStockLeftAttribute()
    {
        return collect($this->discountcodes)->reject(function ($code) {
            return $code->isBought;
        })->count();
    }
