如何使用访问器从二进制字段创建文本字段？

Question

In Laravel 5, I have a binary field called 'microchip,' which is a binary field. I would like to build an accessor function which outputs "yes," or "no," if the original field contains a 1 or 0 respectively. I have this:

    public function getMicrochipTextAttribute($input)
    {
    switch($input)
    {
        case 0:
            return "No";
        break;
        case 1:
            return "Yes";
        break;
    }
}

Unfortunately, when I use $model->microchip_text, it is returning "No," regardless of the contents of the $input. Regardless of whether $input contains a 1 or 0, it is outputting "No."

The reason for that is because Eloquent doesn't know what $input you are using, because you are creating a accessor for a new property and not for an existing one. Instead, try this:

public function getMicrochipTextAttribute()
{
    switch($this->attributes['microchip'])
    {
        case 0:
            return "No";
        break;
        case 1:
            return "Yes";
        break;
    }
}

or a shorter version:

public function getMicrochipTextAttribute()
{
    return $this->attributes['microchip'] ? 'Yes' : 'No';
}
