原则无法在链中映射实体/存储库名称空间

问题描述

我正在尝试使用主义设置symfony，配置主义对我来说是新的。

I'm trying to setup symfony with doctrine, configuring doctrine is new for me.

我尝试通过使用以下代码从数据库中检索实体我的控制器：

I try to retrieve a entity from the database by using the following code in my controller:

$ feedImport = $ this-> getDoctrine（）-> getRepository（MyClass :: class）;

但是我一直收到 MappingException 错误：

在链配置的名称空间中找不到类'AppBundle\Entity\MyClass'

我还尝试手动指定完全限定的类名。但这无济于事。

I also tried to manually specify the fully qualified class name. But this didn't help.

但是我的错误信息似乎表明我需要做一些额外的配置：我需要添加实体/ repositories到配置的名称空间链。但是我在找到该链以及如何配置它方面遇到一些麻烦（如果我的假设是正确的话）

However the way I looked to it the error message seems to suggest I need to do some additional configuring: that I need to add my entities/repositories to "The chain of configured namespaces". But I have some trouble finding this chain and how to configure it (if my assumptions are correct ofcourse)

问题＃1：是否存在某种命名空间链？如果在哪里可以看到如何配置它的示例？

Question #1: Is there some kind of namespace chain? If there is where can I see examples of how to configure it?

所有实体信息都在我的 AppBundle 中束。请参阅下面的包结构：

All the entity information is in my AppBundle bundle. see the bundle structure below:

...
└── AppBundle
    ├── AppBundle.php
    ├── Controller
    │   └── DefaultController.php
    ├── Entity
    │   └── MyClass.php
    ├── Repository
    │   └── MyClassRepository.php
    └── Resources
        └── config
            └── doctrine
                └── MyClass.orm.yml
...

我使用symfony bin\控制台工具。

I generated the entity class / repository / orm.yml files using the symfony bin\console tool.

如果我使用相同的控制台工具使用以下命令检查学说映射信息：
doctrine：mapping：info 命令我告诉我这些类已正确/成功映射：

If i use the same console tool to check the doctrine mapping info with:doctrine:mapping:info command I show me that the classes are correctly/sucessfuly mapped:

Found 1 mapped entity:
[OK]   AppBundle\Entity\MyClass

关于模型/实体配置文件的生成过程。
我使用symfony 控制台工具生成了元数据yaml文件。通过运行以下命令： doctrine：mapping：import 。在创建了yml文件之后，我使用了'doctrine：generate：entities'来生成enity类。

About the process of generation of the models/entity configuration files.I generated the meta data yaml files using the symfony console tool. By running the command: doctrine:mapping:import. After the yml files where created I used 'doctrine:generate:entities' to generate the enity classes.

给我的印象是，如果生成文件并将它们存储在 Entity 文件夹中的工作包中， auto_mapping：true 会自动处理此映射问题。

I was under the impression that if the files where generated and store in a working bundle in the Entity folder, the auto_mapping: true would automatically take care of this mapping thingy.

此假设正确吗？如果不是，请告诉我出什么问题了。

Is this assumption correct? If not please tell me what is wrong.

AppBundle 已注册并正在运行（控制器为

Any words of advise is appreciated!.

推荐答案

经过长时间的努力，我发现了导致问题的原因。
我的symfony环境在 prod 模式下运行。我切换到 dev 。

After a long struggle I found out what caused the problem. My symfony environment was running in prod mode. I switched to dev. And it all worked like a charm.

但是我仍然想知道为什么？！我检查了 AppKernel.php ，它看起来像：

But i'm still wondering why?! I checked The AppKernel.php and it looks like:

$bundles = [
    new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
    new Symfony\Bundle\SecurityBundle\SecurityBundle(),
    new Symfony\Bundle\TwigBundle\TwigBundle(),
    new Symfony\Bundle\MonologBundle\MonologBundle(),
    new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
    new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
    new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
    new AppBundle\AppBundle(),
];

if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
    $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
    $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
    $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();

    if ('dev' === $this->getEnvironment()) {
        $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        $bundles[] = new Symfony\Bundle\WebServerBundle\WebServerBundle();
    }
}

return $bundles;

在我看来，无论我在哪种环境下运行，都必须遵守学说。有人可以向我解释这种行为的原因。

It seems to me no matter what environment I run, doctrine is loaded. Can somebody explain to me the reason behind this behaviour.

编辑：

我发现了更多东西，我换了再次进入 prod 环境，但是现在我开始打开/关闭调试功能。

I discovered something more, I switched to prod environment again but now I started flipping debugging on/off.

现在，我看到它在生产模式下可以很好地工作，但只有在启用调试后才可以。为什么？

Now I see that is works nicely in production mode but only when debugging is enabled. Why?
