Question

When generating a bundle, are TitleCase names valid? For example with Acme\TitleCaseBundle Symfony2 will automatically assume routes are to be prefixed with acme_title_case, services are acme_title_case.example: and in Acme\TitleCaseBundle\DependencyInjection\Configuration, the root node for the configuration tree is found with this method

<?php
// ...

public function getConfigTreeBuilder()
{
    $treeBuilder = new TreeBuilder();
    $rootNode = $treeBuilder->root('acme_title_case');
    // ...
}

It’s supposed to be acme_titlecase !

Trying to correct these, then adding acme_titlecase: ~ to app/config/config.yml will throw this error

InvalidArgumentException: There is no extension able to load the configuration for 
"acme_titlecase" (in /Users/me/Sites/MySite/app/config/config.yml).
Looked for namespace "acme_titlecase", 
found "framework", "another_namespace", ... , "acme_title_case", ...

Thanks to a post by Matthias Noback, the solution is to override getAlias() method and return whatever you like.

<?php

namespace Acme\TitleCaseBundle\DependencyInjection;

// ...

class AcmeTitleCaseExtension extends Extension
{
    // ...

    public function getAlias()
    {
        return 'acme_titlecase';
    }
}
