所以我有一个名为VIP的模型，它有很多相关信息。因此，当我们走到路线vip/{id}时，我会返回大部分信息。然而，当我转到vips/{per-page}时，我不想返回所有数据，因为API将以指数级速度减慢。相反，我宁愿退回一些更基本的东西。
为了做到这一点，我有一个Transformer，它在顶部创建基本响应，然后进入下面一些更复杂的关联，然后返回全部。如果为true，我想向transformer发送某种只返回基本响应的标志。然而，我正在使用分形，似乎无法找到将此标志发送到转换器的方法。
VipsController@index：
/**
* Display a listing of the resource.
*
* @return 'Illuminate'Http'Response
*/
public function index(Request $request, $perPage = 15)
{
$page = $request->input('page');
$vip = Cache::tags(['vips'])->remember("vip.index.$perPage.$page", 60, function() use ($perPage){
Log::info('getting data from the database');
return $this->vip->paginate($perPage, ['*'], ['gender','status','local','jobClass','nonMember','initiationDate','pensioner']);
});
return $this->fractal->paginatedCollection($vip, new VipTransformer());
}
VipTransformer@transform：
public function transform(Vip $vip)
{
$response = [
'id' => $vip->vip_id,
'first_name' => isset($vip->first_name) ? $vip->first_name : '',
'last_name' => isset($vip->last_name) ? $vip->last_name : '',
'birth_date' => isset($vip->birth_date) ? $vip->birth_date : '',
'deceased_date' => isset($vip->deceased_date) ? $vip->deceased_date : '',
'divorced_date' => isset($vip->divorced_date) ? $vip->divorced_date : '',
'marriage_date' => isset($vip->marriage_date) ? $vip->marriage_date : '',
'initiation_date' => isset($vip->initiationDate->date_value) ? $vip->initiationDate->date_value : '0000-00-00',
'gender' => isset($vip->gender->code_description) ? $vip->gender->code_description : '',
'status' => isset($vip->status->code_description) ? $vip->status->code_description : '',
'local' => isset($vip->local) ? "{$vip->local->local_code} - {$vip->local->local_name}" : '',
'jobClass' => isset($vip->jobClass) ? $vip->jobClass->code_description : '',
'nonMember' => isset($vip->nonMember) ? $vip->nonMember->code_description : '',
'age' => isset($vip->birth_date) && $vip->birth_date !== '0000-00-00' ? Carbon::parse($vip->birth_date)->age : 0,
];
// Grab retirement date from pension tables
$response['retirement_date'] = $vip->pensioner->retirement_date ?? '0000-00-00';
// Grab the associated information for the vip profile
$reciprocals = [];
$addresses = [];
$phone_numbers = [];
$emails = [];
foreach($vip->addresses as $address) {
$addresses = [
'address1' => $address->address_1 ?? '',
'address2' => $address->address_2 ?? '',
'city' => $address->city ?? '',
'zip' => $address->zip_code ?? '',
'country' => $address->country->code ?? '',
'state' => $address->state->state_province_code ?? '',
'is_default' => $address->is_default ?? false,
];
}
// TODO: Add record status trait to each
foreach ($vip->phones as $phone) {
$phone_numbers[] = [
'extension' => $phone->extension ?? '',
'number' => $phone->phone_number ?? '',
'is_default' => $phone->is_default ?? false,
];
}
foreach ($vip->emails as $email) {
$emails[] = [
'email_address' => $email->email_address ?? '',
'is_default' => $email->is_default ?? false,
];
}
foreach ($vip->reciprocalMembers as $member) {
$reciprocals[] = $member->effective_date . ' - ' . $member->fund->fund_abbreviation . ' - ' . $vip->local->local_name;
}
$response['addresses'] = $addresses;
$response['phone_numbers'] = $phone_numbers;
$response['emails'] = $emails;
$response['reciprocals'] = $reciprocals;
return $response;
}
有没有一种方法可以让我使用Fractal将标志发送到转换器？也许还有更好的方法吗？
更新：
答案是有效的，但我是这样做的。。。。随心所欲：
变压器：
protected $indexRequest;
public function __construct($indexRequest = null)
{
$this->indexRequest = $indexRequest ?? false;
}
分形调用：
return $this->fractal->paginatedCollection($vips, new VipTransformer(true));
我从未使用过分形，但你不能做一些事情，比如在VipTransformer类上添加一个标志吗。
<?php
class VipTransformer
{
protected $basicResponseFlag = false;
public function setFlag($flag)
{
$this->basicResponseFlag = $flag;
}
public function transform(Vip $vip)
{
if($this->basicResponseFlag){
//do basic stuff
}
}
}
现在开始你的VipsController@index：
/**
* Display a listing of the resource.
*
* @return 'Illuminate'Http'Response
*/
public function index(Request $request, $perPage = 15)
{
$page = $request->input('page');
$vip = Cache::tags(['vips'])->remember("vip.index.$perPage.$page", 60, function() use ($perPage){
Log::info('getting data from the database');
return $this->vip->paginate($perPage, ['*'], ['gender','status','local','jobClass','nonMember','initiationDate','pensioner']);
});
$vipTransformer = new VipTransformer();
$vipTransformer->setFlag(true); //set your transfomer to basic mode
return $this->fractal->paginatedCollection($vip, $vipTransformer);
}
