是否可以在 API 响应中 return 不同的模型
is it possible to return different models in an API response
这是我第一次在这里发帖,请原谅我的错误:
我有一个搜索功能,其路线是:
Route::get('/search', 'SearchController@index');
目前,我有一个 eloquent 关系,产品有很多交易。是否可以 return 一个单级深度数组执行以下操作:
- 如果产品有有效的交易,return只有交易;
- 否则,return产品本身。
这是我之前在 Product.php 中实现的内容:
public function deals()
{
return $this->hasMany(Deal::class, 'product_id');
}
Deal.php
public function product()
{
return $this->hasOne(Product::class, 'id', 'product_id');
}
搜索控制器:
public function index(Request $request)
{
$per_page = $request->per_page ?? 10;
$products = Product::query()->latest()
->when($request->query('filter'), function ($query) use ($request) {
$query->with('deals')->where('title', 'LIKE', "%$request->filter%");
})
->when($request->query('category'), function ($query) use ($request) {
$query->with('deals')->whereHas('categories', function ($q) use ($request) {
$q->where('title', 'LIKE', "%$request->category%");
});
})
->paginate($per_page);
return new PaginatedCollection($products, ProductResource::class);
}
在我的 ProductResource 中:
<?php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class ProductResource extends JsonResource
{
public function toArray($request)
{
$details = array_filter($this->details ?: [], function ($d) {
return $d != "";
});
$personalizedOptions = array_filter($this->personalized_options ?: [], function ($o) {
return $o != "";
});
return [
'id' => $this->id,
'createdAt' => $this->created_at,
'updatedAt' => $this->updated_at,
'title' => $this->title,
'sellerId' => $this->sellerId,
'description' => $this->description,
'categories' => CategoryResource::collection($this->categories),
'details' => $details,
'active' => (bool) $this->active,
'defaultPreviewImageId' => $this->default_preview_image_id,
'originalPrice' => $this->originalPrice,
'shippingPrice' => $this->shippingPrice,
'shippingWeightLbs' => $this->shippingWeightLbs,
'shippingWeightOz' => $this->shippingWeightOz,
'shippingMaxDays' => $this->shipping_max_days,
'shippingMinDays' => $this->shipping_min_days,
'personalized' => (bool) $this->personalized,
'personalizedOptions' => $personalizedOptions,
'deals' => $this->deals ?? null,
'options' => ProductOptionResource::collection($this->productOptions),
'images' => ImageResource::collection($this->images->whereNull('meta')),
'preview' => new ImageResource($this->images->where('meta', '=', 'preview')->first()),
];
}
}
现在,我已将 ProductResource 重构为此,但这都是 returning null
响应

namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class ProductResource extends JsonResource
{
public function toArray($request)

return $d != "";
});
$personalizedOptions = array_filter($this->personalized_options ?: [], function ($o) {
return $o != "";
});
if($this->deals){
DealResource::collection($this->deals);
}else{
return [
'id' => $this->id,
'createdAt' => $this->created_at,
'updatedAt' => $this->updated_at,
'title' => $this->title,
'sellerId' => $this->sellerId,
'description' => $this->description,
'categories' => CategoryResource::collection($this->categories),
'details' => $details,
'active' => (bool) $this->active,
'defaultPreviewImageId' => $this->default_preview_image_id,
'originalPrice' => $this->originalPrice,
'shippingPrice' => $this->shippingPrice,
'shippingWeightLbs' => $this->shippingWeightLbs,
'shippingWeightOz' => $this->shippingWeightOz,
'shippingMaxDays' => $this->shipping_max_days,
'shippingMinDays' => $this->shipping_min_days,
'personalized' => (bool) $this->personalized,
'personalizedOptions' => $personalizedOptions,
// 'deals' => $this->deals ?? null,
'options' => ProductOptionResource::collection($this->productOptions),
'images' => ImageResource::collection($this->images->whereNull('meta')),
'preview' => new ImageResource($this->images->where('meta', '=', 'preview')->first()),
];
}
}
}
条件检查可能给出空结果的原因。它是 return 一个数组,您需要将其更新为此。
if(count($this->deals))
这将检查交易数组是否包含数组中的元素。如果不是,它将 return 个产品。
