copied!<p>I created a Configuration class and build a tree that defines my configuration in that class,but i guess it's very ugly then my question is to find a solution to simplify my calss?</p> <pre><code><?php namespace Myapp\Mybundle\DependencyInjection; use Symfony\Component\Config\Definition\Builder\ArrayNodeDefinition; use Symfony\Component\Config\Definition\Builder\TreeBuilder; use Symfony\Component\Config\Definition\ConfigurationInterface; class Configuration implements ConfigurationInterface { /** * {@inheritDoc} */ public function getConfigTreeBuilder() { $treeBuilder = new TreeBuilder(); $rootNode = $treeBuilder->root('em_profession'); $rootNode ->children() ->arrayNode('region') ->isRequired() ->requiresAtLeastOneElement() ->useAttributeAsKey('id') ->prototype('array') ->children() ->scalarNode('label') ->isRequired() ->cannotBeEmpty()->defaultValue('em_profession_label')->end() ->arrayNode('childrens') ->isRequired() ->requiresAtLeastOneElement() ->useAttributeAsKey('id') ->prototype('array') ->children() ->scalarNode('label')->end() ->arrayNode('childrens') ->isRequired() ->requiresAtLeastOneElement() ->useAttributeAsKey('id') ->prototype('array') ->children() ->scalarNode('label')->end() ->arrayNode('childrens') ->isRequired() ->requiresAtLeastOneElement() ->useAttributeAsKey('id') ->prototype('array') ->children() ->scalarNode('label')->end() ->arrayNode('childrens') ->isRequired() ->requiresAtLeastOneElement() ->useAttributeAsKey('id') ->prototype('array') ->children() ->scalarNode('label')->end() ->arrayNode('childrens') ->isRequired() ->requiresAtLeastOneElement() ->useAttributeAsKey('id') ->prototype('array') ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ->end() ; return $treeBuilder; } </code></pre> <p>My configuration works fine but it's very big so I wich to minimise it to simplify it and to stop the repetition of code...</p> <p><strong>edit</strong></p> <p>OK I know this solution but I guess I cant applicate it in my configuration,for exemple in Twig configuration file they use a custom function in the end of class after "->end()" but in my configuration i use it inside "prototype()" also I have a lot of repetition of code but child inside child inside child...so it's deficult to minimise it correctly... </p>
