php - 使用 Doctrine-Fixture 加载数据时，requestStack getCurrentRequest 在服务中为空
问题描述
所以，这是我在 stackoverflow 上的第一篇文章，如果我错过了一些强制性信息，请见谅。
让我解释一下我面临的问题。
在尝试使用 Doctrine-fixture command: 加载数据php bin/console doctrine:fixture:load -e test时，我收到以下错误：
In DebtService.php line 152:
Call to a member function getSession() on null
那么，这是如何发生的，我有一个 pre persist 事件侦听器，它调用我的 DebtService 以检查是否可以使用付款来偿还债务。
我在用 ：
Symfony: ~3.4.*
Doctrine-Fixture-bundle: 3.0
这是我用来加载数据的类
class LoadBasicData extends Fixture implements FixtureInterface
{
private $container;
public function load(ObjectManager $manager)
{
new Session(new MockFileSessionStorage());
$entities = array(
Client::class,
Landlord::class,
Contact::class,
Month::class,
Year::class,
Honorary::class,
Room::class,
Pension::class,
Warranty::class,
Flat::class,
Contract::class,
Debt::class,
PiggyBank::class,
Transfer::class,
Material::class,
Budget::class,
Cleaning::class,
Expense::class,
ClientPayment::class, // Class That makes the error pop up
//Payment::class
);
foreach($entities as $entity){
$object = new $entity();
$className =explode('\\', get_class($object));
$objName=end($className);
if(method_exists($object, "test")) {
$object = $object->test(); // Returns the object with mocked values
if(method_exists($object, "setDate")){
$object->setDate(new \Datetime("now"));
}
if(method_exists($object, "setRoom")){
$object->setRoom($this->getReference("Room"));
}
if(method_exists($object, "addRoom")){
$object->addRoom($this->getReference("Room"));
}
if(method_exists($object, "setClient")){
$object->setClient($this->getReference("Client"));
}
if(method_exists($object, "setHonorary")){
$object->setHonorary($this->getReference("Honorary"));
}
if(method_exists($object, "setAdministrationHonorary")){
$object->setAdministrationHonorary($this->getReference("Honorary"));
}
if(method_exists($object, "setLandlord")){
$object->setLandlord($this->getReference("Landlord"));
}
if(method_exists($object, "setWarranty")){
$object->setWarranty($this->getReference("Warranty"));
}
if(method_exists($object, "setMonth")){
$object->setMonth($this->getReference("Month"));
}
if(method_exists($object, "setYear")){
$object->setYear($this->getReference("Year"));
}
if(method_exists($object, "addMaterial")){
$object->addMaterial($this->getReference("Material"));
}
if(method_exists($object, "addClientPayment")){
$object->addClientPayment($this->getReference("ClientPayment"));
}
if(method_exists($object, "setPension") && $objName != "Room"){
$object->setPension($this->getReference("Pension"));
}
$this->addReference($objName, $object);
$manager->persist($object);
$manager->flush();
}
}
}
}

}
}else{

$this->reduceClientDebt($clientPayment->getPenaltyAmount(),$clientPayment);
}
}
}
}
我试过评论 $request->getSession(); // 它适用于测试，但我的应用程序中丢失了 flashBags。
这是我第一次在我的应用程序中实现 Test / Doctrine-Fixture。我对这件事的了解仍然有限。
谢谢你的帮助。

解决方案
好的，我找到了解决问题的方法。
LoadBasicData 作为一项服务，我注入了@requestStack 并创建了一个新的请求/会话。
服务.yml
services:
loadBasicData:
class: AD\CoreBundle\DataFixtures\ORM\LoadBasicData
arguments: ["@request_stack"]
tags: ['doctrine.fixture.orm']
并添加到我的构造函数中：LoadBasicData.php
protected $requestStack;
public function __construct(RequestStack $requestStack){
$this->requestStack = $requestStack;
$request = new Request();
$request->setSession(new Session());
$this->requestStack->push($request);
}
