Laravel - Getting Started - Allowing Mass Assignment

If you would like to make all of your attributes mass assignable, you may define your model's $guarded property as an empty array. If you choose to unguard your model, you should take special care to always hand-craft the arrays passed to Eloquent's fill, create, and update methods:

     * The attributes that aren't mass assignable.
     * @var array
    protected $guarded = [];
