    <p>I'd like to propose different solution to your original problem.You can use <a href="http://api.symfony.com/2.3/Symfony/Component/DependencyInjection/Loader/PhpFileLoader.html" rel="nofollow">PhpFileLoader</a> to dynamically define parameters for your config.yml.</p> <ol> <li><p>Extract you main database connection parameters into separate file:</p> <pre><code># src/Blogger/BlogBundle/Resources/config/parameters.yml parameters: main_db_name: maindb main_db_user: root main_db_password: null main_db_host: localhost </code></pre></li> <li><p>Create new PHP script (say DynamicParametersLoader.php) which will inject new parameters in app container. I think you cannot use your symfony app in this script, but you can read main db credentials from $container variable. Like the following:</p> <pre><code># src/Blogger/BlogBundle/DependecyInjection/DynamicParametersLoader.php &lt;?php $mainDbName = $container-&gt;getParameter('main_db_name'); $mainDbUser = $container-&gt;getParameter('main_db_user'); $mainDbPassword = $container-&gt;getParameter('main_db_password'); $mainDbHost = $container-&gt;getParameter('main_db_host'); # whatever code to query your main database for dynamic DB credentials. You cannot use your symfony2 app services here, so it ought to be plain PHP. ... # creating new parameters in container $container-&gt;setParameter('dynamic_db_name', $dbName); $container-&gt;setParameter('dynamic_db_user', $dbUser); $container-&gt;setParameter('dynamic_db_password', $dbPass); </code></pre></li> <li><p>Now you need to tell Symfony about your script and new parameters.yml file:</p> <pre><code># config.yml imports: - { resource: parameters.yml } - { resource: ../../DependencyInjection/DynamicParametersLoader.php } </code></pre></li> <li><p>At this step you can freely use injected parameters in you config:</p> <pre><code># config.yml ... dynamic_conn: dbname: %dynamic_db_name% user: %dynamic_db_user% password: %dynamic_db_password% ... </code></pre></li> </ol>

    1. COThis solution will not work because parameters are already replaced in placeholders. Also, you will regenerate a new container each time you need to change. It will be a performance murder.

    2. COAlexandre, there are different parameters in placeholders (dynamic_db_name vs main_db_name).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
