向 Laravel model 添加过滤器辅助方法

Question

I'd like to add a method to my Laravel Product model which filters by name attr and returns a collection of all matching products, here's what I've got:

Product.php

public function filterByName($query)
{
    return $this->where('name','LIKE','%'.$query.'%')->get();
}

ProductController.php

$products = collect(new Product);
$products->filterByName($name);

What's the correct usage of this? Do I need to use a QueryFilter?

Answer 1

Are you talking about scope?

public function scopeByName($query, $param)
{
    return $query->where('name','LIKE','%'.$param.'%');
}

and then

$products = Product::byName('xyz')->get();
