主义2:类型x已经存在 [英] Doctrine2: Type x already exists

问题描述

我的Doctrine API有问题.

I have a problem with the Doctrine API.

我想添加一个新的教义类型.我按照本文档创建了该类，并在自定义驱动程序中添加了该类型.

I want to add a new Doctrine Type. I followed this documentation to create the class, and I have added the type in my custom driver.

Type::addType("custom", "Namespace\NameBundle\Types\CustomType");
$this->registerDoctrineTypeMapping("CustomType", "custom");

我的问题在执行php app/控制台缓存时清除:清除.

My problem append when I execute php app/console cache:clear.

[Doctrine\DBAL\DBALException]
Type custom already exists.

经过几次搜索，我发现在Doctrine \ DBAL \ Types \ Type :: addType(...)中，如果知道类型，则会引发异常……我不明白为什么会引发此错误.

After few searches, I have found in Doctrine\DBAL\Types\Type::addType(…) throw an exception if the type is knew… I don't understand why this error is throwing.

推荐答案

我发现了我的问题！

我不知道为什么，但是我的自定义类型一次又一次地加载.

I don't know why, but my custom type is loading again and again.

要解决此问题，请添加类似检查的代码.

To resolve this problem, adding this code like checking.

if (!Type::hasType("custom")) {
    Type::addType("custom", "Namespace\NameBundle\Types\CustomType");
    $this->registerDoctrineTypeMapping("CustomType", "custom");
}

它有效！
