我想在配置文件 (config.yml) 中添加一个简单的值列表.例如:
I would like to add a simple list of values in a configuration files (config.yml). For example :
my_bundle:
columns: ["col1", "col2"]
将节点添加到配置解析器时,它只是失败了:
When adding the node to the configuration parser, it simply fails :
$rootNode = $treeBuilder->root('my_bundle');
$rootNode->arrayNode('columns')->children()->end();
这是错误:
InvalidConfigurationException: Unrecognized options "0, 1" under "my_bundle.columns"
我错过了什么?这甚至可能吗?
What am I missing? Is this even possible?
如果你想实现这样的节点,只需:
If you want to achieve a node like this, just do:
$rootNode
->children()
->arrayNode('columns')
->prototype('scalar')
->end()
->end()
->end()
;
