Laravel 调用模型 [应用\产品] 上未定义的关系 [品牌]

Question

我正在尝试返回带有资源的模型数据，但它说：调用模型 [应用\产品] 上的未定义关系 [品牌]。法典product.phppublic function brand(){  return $this->belongTo(Brand::class);}brand.phppublic function products(){  return $this->hasMany(Product::class);}controllerpublic function show($slug){  $product = Product::where('slug', $slug)->with(['photos', 'variations', 'options', 'brand'])->where('active', 'yes')->first();  return response()->json([    'data' => new ProductFrontResource($product),    'message' => 'Product retrieved successfully.',  ]);}ProductFrontResource.phpuse App\Http\Resources\CategoryResource;class ProductFrontResource extends JsonResource{    public function toArray($request)    {        $arrayData = [            'id' => $this->id,            'name' => $this->name,            'slug' => $this->slug,            'brand' => $this->brand->name,            'categories' => CategoryResource::collection($this->whenLoaded('categories')),            'created_at' => (string) $this->created_at,            'updated_at' => (string) $this->updated_at,        ];        return $arrayData;    }}有什么想法吗？更新如果我从零件中删除它说：brandwith()Call to undefined method App\Product::belongTo()

将品牌关系改变成这样。

public function brand(){
  return $this->belongsTo(Brand::class);
}
