Doctrine cannot map entity/repository namespace in chain

Question

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

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

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

But I keep getting the MappingException error:

The class 'AppBundle\Entity\MyClass' was not found in the chain configured namespaces

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

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)

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

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
...

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

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

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.

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.

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

• The entity files and configuration are stored under the working bundle AppBundle

• The AppBundle is registered and working (the controller is doing his thing)

• The command: doctrine:mapping:info seems to map the entities right away.

For the full code of the Entity Model:

Any words of advise is appreciated!.

Answer 1

try this:

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

if you want to access a particular function/method

$feedImport = $this->getDoctrine()->getRepository('AppBundle:MyClass')->sampleMethod();

Answer 2

Your bundle isn't declare in the AppKernel file or your doctrine mapping isn't reconized.

You should have in your AppKernel :

public function registerBundles()
{
    $bundles = array(
        ...
        new AppBundle\AppBundle(),
    );

    ....

    return $bundles;
}

And by default in your config.yml :

orm:
    auto_generate_proxy_classes: %kernel.debug%
    auto_mapping: true

Answer 3

Try this:

/**
 *
 * @ORM\Table(name="my_table_name")
 * @ORM\Entity()
 */
class MyClass

Answer 4

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.

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;

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

EDIT:

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

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