Symfony：get（） - 这究竟是如何工作的？

Question

I have a line in a sample Symfony app that reads:

$seo = $this->get('sonata.seo.page');

However the config.yml file reads:

sonata_seo:
page:
    metas:
        property: ... etc ...

I've read http://symfony.com/doc/current/service_container.html but I'm not clear how exactly the get('sonata.seo.page') works. Does it somehow equate to the key / values in the config file? i.e. does the underscore in sonata_seo get magically changed to a period?

Answer 1

You cannot access values in config.yml direcly, like values in parameters.yml.

That file can store configuration values for bundles thought.
