用于集合的 Laravel 5.5 API 资源(独立数据)
我想知道是否可以为项目资源和集合资源定义不同的数据.
I was wondering if it is possible to define different data for item resource and collection resource.
对于收藏,我只想发送 ['id', 'title', 'slug']
但项目资源将包含额外的详细信息 ['id', 'title','slug'、'user' 等]
For collection I only want to send ['id', 'title', 'slug']
but the item resource will contain extra details ['id', 'title', 'slug', 'user', etc.]
我想实现以下目标:
class PageResource extends Resource
{
/**
* Transform the resource into an array.
*
* @param IlluminateHttpRequest
* @return array
*/
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'slug' => $this->slug,
'user' => [
'id' => $this->user->id,
'name' => $this->user->name,
'email' => $this->user->email,
],
];
}
}
class PageResourceCollection extends ResourceCollection
{
/**
* Transform the resource collection into an array.
*
* @param IlluminateHttpRequest
* @return array
*/
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'slug' => $this->slug,
];
}
}
PageResourceCollection 不会按预期工作,因为它使用了 PageResource,所以它需要
PageResourceCollection will not work as expected because it uses PageResource so it needs
return [
'data' => $this->collection,
];
我可以将资源复制到 PageFullResource
/PageListResource
和 PageFullResourceCollection
/PageListResourceCollection
但我试图找到达到相同结果的更好方法.
I could duplicate the resource into PageFullResource
/ PageListResource
and PageFullResourceCollection
/ PageListResourceCollection
but I am trying to find a better way to achieve the same result.
推荐答案
Resource 类有一个集合方法.您可以将其作为参数输入返回到您的 ResourceCollection,然后在集合上指定您的转换.
The Resource class has a collection method on it. You can return that as the parameter input to your ResourceCollection, and then specify your transformations on the collection.
控制器:
class PageController extends Controller
{
public function index()
{
return new PageResourceCollection(PageResource::collection(Page::all()));
}
public function show(Page $page)
{
return new PageResource($page);
}
}
资源:
class PageResource extends Resource
{
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'slug' => $this->slug,
'user' => [
'id' => $this->user->id,
'name' => $this->user->name,
'email' => $this->user->email,
],
];
}
}
class PageResourceCollection extends ResourceCollection
{
public function toArray($request)
{
return [
'data' => $this->collection->transform(function($page){
return [
'id' => $page->id,
'title' => $page->title,
'slug' => $page->slug,
];
}),
];
}
}
