    <p>Finding a solution for reusing entity annotations between different database platforms I reach this:<br> I have a solution for rename tableName on entity classes metadata listening loadClassMetada event:</p> <p>My services.xml</p> <pre class="lang-xml prettyprint-override"><code>&lt;service id="framework.loadclassmetadata.listener" class="%framework.loadclassmetadata.listener.class%"&gt; &lt;tag name="doctrine.event_listener" event="loadClassMetadata" method="loadClassMetadata"/&gt; &lt;call method="setContainer"&gt;&lt;argument type="service" id="service_container" /&gt;&lt;/call&gt; &lt;/service&gt; </code></pre> <p>My Listener class:</p> <pre class="lang-php prettyprint-override"><code>&lt;?php namespace Fluency\Bundle\FrameworkBundle\EventListener; use Doctrine\ORM\Event\LoadClassMetadataEventArgs; use Doctrine\ORM\Mapping\ClassMetadataInfo; use Symfony\Component\DependencyInjection\ContainerAware; /** * Class LoadClassMetadataListener * * @package Fluency\Bundle\FrameworkBundle\EventListener */ class LoadClassMetadataListener extends ContainerAware { /** * @param LoadClassMetadataEventArgs $args */ public function loadClassMetadata(LoadClassMetadataEventArgs $args) { $connection = $this-&gt;container-&gt;get('database_connection'); $classMetadata = $args-&gt;getClassMetadata(); if(!$connection-&gt;getDatabasePlatform()-&gt;supportsSchemas()) { $tableName = $classMetadata-&gt;table['name']; $classMetadata-&gt;table['name'] = str_replace('.', '_', $tableName); foreach ($classMetadata-&gt;getAssociationMappings() as $fieldName =&gt; $mapping) { if ($mapping['type'] == ClassMetadataInfo::MANY_TO_MANY) { if(isset($classMetadata-&gt;associationMappings[$fieldName]['joinTable']['name'])) { $mappedTableName = $classMetadata-&gt;associationMappings[$fieldName]['joinTable']['name']; $classMetadata-&gt;associationMappings[$fieldName]['joinTable']['name'] = str_replace('.', '_', $mappedTableName); } } } } } } </code></pre> <p>And a solution for create schemas on database platforms like postgresql:</p> <pre class="lang-php prettyprint-override"><code>&lt;?php namespace Fluency\Bundle\FrameworkBundle\EventListener; use Doctrine\DBAL\DBALException; use Doctrine\DBAL\Event\SchemaCreateTableEventArgs; use Symfony\Component\DependencyInjection\ContainerAware; /** * Class SchemaCreateTableListener * * @package Fluency\Bundle\FrameworkBundle\EventListener */ class SchemaCreateTableListener extends ContainerAware { /** * @var array */ private $_createdSchemas = array(); /** * @param SchemaCreateTableEventArgs $args */ public function onSchemaCreateTable(SchemaCreateTableEventArgs $args) { $connection = $this-&gt;container-&gt;get('database_connection'); if ($args-&gt;getPlatform()-&gt;supportsSchemas()) { $tableName = $args-&gt;getTable()-&gt;getName(); $separetedTableName = explode('.', $tableName); if (count($separetedTableName) == 2) { $schemaName = $separetedTableName[0]; if (!in_array($schemaName, $this-&gt;_createdSchemas)) { try { $connection-&gt;exec(sprintf("CREATE SCHEMA %s", $schemaName)); } catch (DBALException $e) { } $this-&gt;_createdSchemas[] = $schemaName; } } } } } </code></pre> <p>All works fine but I think that it's not optimal cause on every time I need class metadata the eventlistener is called by the main entity and each related entity. I though a dirty solution with a command changing annotations by the hard way, reading Entities and replacing tablenames using regexp. (file_get_contents, regexp replacement and file_put_contents)... but don't like me.</p> <p><strong>My question (finally) is if its possible, when symfony2-doctrine2 generates annotations cache and or proxy classes, set the correct tableName?</strong> then my entities code remains without change and loadClassMetadata method logic it's called only when cache it's generated.</p>

    1. COMy tableName on entity annotations using postgresql/oracle standard schema.tablename and in other database like sqlite and mysql are changed on fly to schema_tablename.

    2. COI don't have an answer to your question, but I will note that all of this is much easier if you can switch/upgrade to PHP 5.4 and use Traits.

    3. COTraits don't solve my problem, they are design for solve conflicts with multiple inheritance and that's not my problem.. but thanks any way...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
