具有多对多关系的分页

cur*_*ved 3 laravel eloquent

我的数据库中有products,categoriescategory_product(枢轴)表。

我想在同一个响应中返回带有分页类别信息产品

我知道我可以使用Product::with('categories')->pagination(20)

但我不想将类别附加到每个产品。

让产品属于特定类别的正确方法是什么?

我试过了,但我无法获得分页:

$category = Category::where('slug', $slug)->first();
$products = $category->products()->paginate(20);
return response()->json([
    'category' => new CategoryResource($category),
    'products' => ProductResource::collection($products),
]);

这是我的产品资源

return [
    'id' => $this->id,
    'name' => $this->name,
    'description' => $this->description,
    'code' => $this->code,
    'image' => $this->image,
    'quantity' => $this->quantity,
    'price' => $this->price,
    'slug' => $this->slug,
    'sort_order' => $this->sort_order,
    'created_at' => $this->created_at,
    'updated_at' => $this->updated_at,
    'categories' => CategoryResource::collection($this->whenLoaded('categories')),
];
