Symfony：auto_mapping和auto_generate_proxy_classes的含义是什么？

问题描述

配置使用：

doctrine:
dbal:
  driver:   "%database_driver%"
   ....
orm:
    auto_generate_proxy_classes: "%kernel.debug%"
    auto_mapping: true

auto_mapping 的确切含义是什么？它被用于真实和虚假的吨数，没有精确的描述。
发生代理生成（如果不是自动）？通过doctrine命令行工具？

What is the exact meaning of auto_mapping? It is used in tons of exemples with true and false, and no precise description.When does occurs the proxy generation if it's not auto ? By doctrine command-line tools ?

推荐答案

auto_mapping 自动从您的包 Resources / config / doctrine 目录中加载映射。

auto_mapping is where doctrine will automatically load the mapping from your bundle Resources/config/doctrine directory.

将其设置为false将意味着您将需要自己加载映射。如果您有实体的映射，而不是要覆盖的供应商捆绑包中的映射超类，那么它可以很方便。

Setting it to false will mean that you will need to load the mappings yourself. It can be handy if you have mappings for entities rather than mapped superclasses in a vendor bundle that you want to override.

您可以通过说明映射在教条配置...

You can do this either by way of stating the mappings in the doctrine config ...

doctrine:
    orm:
        entity_managers:
            default:
                mappings:
                    AcmeUnknownBundle:
                        mapping:              true
                        type:                 yml
                        dir:                  "Resources/config/doctrine"
                        alias:                ~
                        prefix:               Acme\UnknownBundle\Entity
                        is_bundle:            true

将它们添加到一些一种 ...

adding them in some sort of mappings pass ...

class AcmeUnknownBundle extends Bundle
{
    public function build(ContainerBuilder $container)
    {
        parent::build($container);
        // ...

        $modelDir = realpath(__DIR__.'/Resources/config/doctrine/model');
        $mappings = array(
            $modelDir => 'Acme\UnknownBundle\Model',
        );

        $ormCompilerClass = 'Doctrine\Bundle\DoctrineBundle\DependencyInjection\Compiler\DoctrineOrmMappingsPass';
        if (class_exists($ormCompilerClass)) {
            $container->addCompilerPass(
                DoctrineOrmMappingsPass::createYamlMappingDriver(
                    $mappings,
                    array('acme_unknown.model_manager_name'),
                    true
            ));
        }
    }
}
