我在 YML 中有一个配置,如下所示:

foobar_template:
    templates:
        homepage:
            name: "Homepage template"
            regions: ["top", "main", "left", "bottom"]
            layout:
              - [ { region: "top", colspan: 4 } ]
              - [ { region: "left" }, { region: "main", colspan: 3 } ]
              - [ { region: "bottom", colspan: 4 } ]

        subpage:
            name: "Subpage template"
            regions: ["top", "main"]
            layout:
              - [ { region: "top", colspan: 4 } ]
              - [ { region: "main", colspan: 4 } ]

我一直在尝试确保根据规范定义此配置,但似乎无法确保布局部分包含至少定义一个区域的条目。目前我的 Configuration.php 包含以下内容:

class Configuration implements ConfigurationInterface
{
    /**
     * {@inheritDoc}
     */
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('foobar_template');

        $rootNode
            ->children()
                ->arrayNode('templates')
                    ->useAttributeAsKey('template')
                    ->prototype('array')
                        ->children()
                            ->scalarNode('name')->end()
                            ->arrayNode('regions')
                                ->isRequired()
                                ->requiresAtLeastOneElement()
                                ->prototype('scalar')->end()
                            ->end()
                            ->append($this->addLayoutNode())
                        ->end()
                    ->end()
                ->end()
            ->end();

        return $treeBuilder;
    }

    public function addLayoutNode()
    {
        $builder = new TreeBuilder();
        $node = $builder->root('layout');

        $node
            ->isRequired()
            ->requiresAtLeastOneElement()
            ->prototype('array')
                ->prototype('variable')->end()
            ->end();

        return $node;
    }
}

但我真的很想测试指定的布局块是否包含一个区域(即一个至少包含 的片段- [{ region: <region_name> }],那么我应该使用什么而不是->prototype('variable')->end()addLayoutNode() 来实际执行此测试?我尝试了多种方法,但总是尝试执行此操作时遇到 InvalidDefinitionException 或 InvalidConfigurationException。有人知道如何在 Configuration 中测试上述内容吗?(我目前在 bundle Extension 的负载中进行了一些健全性检查,但如果 Configuration 可以检查它会更干净这个)。

You can use a ConfigurationProccesor: http://symfony.com/doc/2.0/components/config/definition.html#processing-configuration-values or a CompilerPass for the more complex config.
