Few days ago I have struggled with a problem using Symfony2 configuration. I
|
|||
|
|
wanted to add the following kind of configuration to `config.yml`:
|
|||
|
|
|
|||
|
|
{% highlight yaml %}
|
|||
|
|
acme_demo:
|
|||
|
|
transitions:
|
|||
|
|
- { hc_cba: 180 }
|
|||
|
|
- { cba_hc: -1 }
|
|||
|
|
{% endhighlight %}
|
|||
|
|
|
|||
|
|
The problem was that the stuff under `transitions` is dynamic, so those
|
|||
|
|
`hc_cba` and `cba_hc` tags can be pretty much anything. After hitting many
|
|||
|
|
errors, I came to the solution:
|
|||
|
|
|
|||
|
|
{% highlight php %}
|
|||
|
|
<?php
|
|||
|
|
$rootNode
|
|||
|
|
->children()
|
|||
|
|
->arrayNode('state_machine')
|
|||
|
|
->requiresAtLeastOneElement()
|
|||
|
|
->beforeNormalization()
|
|||
|
|
->ifArray()
|
|||
|
|
->then(function($values) {
|
|||
|
|
$ret = array();
|
|||
|
|
|
|||
|
|
foreach ($values as $value) {
|
|||
|
|
foreach ($value as $transition => $time) {
|
|||
|
|
$ret[] = array('transition' => $transition, 'time' => e);
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
return $ret;
|
|||
|
|
})
|
|||
|
|
->end()
|
|||
|
|
->prototype('array')
|
|||
|
|
->children()
|
|||
|
|
->scalarNode('transition')->end()
|
|||
|
|
->scalarNode('time')->end()
|
|||
|
|
->end()
|
|||
|
|
->end()
|
|||
|
|
->end()
|
|||
|
|
->end()
|
|||
|
|
;
|
|||
|
|
{% endhighlight %}
