按供应商分类的产品 - laravel

Question

I am working on a Laravel with MySQL e-commerce like website, and I can show all the products under its categories by vendor/store.

But the problem is, if I added a product under the same category, it also shows to other vendor which also have that category, that shouldn't have happen.

My Query:

$categories = Categories::with('products')
    ->whereHas('products', function ($query) use ($id) {
    $query->where('store_id' ,$id);
})
->get();

I think the problem is in the with part? but I don't know exactly how to do it.

DB Structure:

store

id  |  name


products

id | store_id  | category_id | name


categories
id | name

Answer 1

WhereHas() check if it has it, but does not filter the result. Does it have a product with this store, if yes return all categories where you now includes products that does not filter.

There is an array syntax, for filtering with() call. This will show the products correctly.

Categories::with(['products' => function ($query) use ($id) {
    $query->where('store_id' ,$id);
}])
