WHERE 子句中的 Doctrine Filter 而不是 LEFT JOIN

Question

I have a multi tenant application and i'm using the Doctrine Filters to filter my SQL by client.

So, when i want a list of my client Projects i just need to do a "getAll" and the filter will automatically append the SQL on the WHERE clause, like this:

SELECT * 
FROM projects p
WHERE p.client_id = 1 #(appended by the filter)

My problem is when i want for example the ProjectMembers . The filter will add the SQL to the LEFT JOIN, not to the WHERE clause, making useless the filter because will return all the ProjectMembers , even they aren't from the client 1.

SELECT * 
FROM projects p
LEFT JOIN project_members pm ON pm.project_id = p.id 
AND p.client_id = 1 #(appended by the filter)

This is my addFilterConstrait

public function addFilterConstraint(ClassMetaData $targetEntity, $targetTableAlias)
{
    $class = $targetEntity->getName();

    if (array_key_exists($class, $this->disabled) && $this->disabled[$class] === true) {
        return '';
    } elseif (array_key_exists($targetEntity->rootEntityName, $this->disabled) && $this->disabled[$targetEntity->rootEntityName] === true) {
            return '';
    }

    $config = $this->getFilterConfig($targetEntity->getReflectionClass());

    if (!isset($config['clientFilter']) || !$config['clientFilter']) {
        return '';
    }

    return $targetTableAlias. '.' . $config['columnName'] . ' = ' . $this->getParameter('client'); // getParameter applies quoting automatically
}

Any ideas how can i solve this, adding the filter to the WHERE instead of the LEFT JOIN?

The more SQL you do in Symfony you will soon see it is much easier to create a repository for your entity, use one for each or share a common repository with multiple entities. Then write your DQL in the repository. Note: DQL is a lot like SQL but it has its limitations.

https://symfony.com/doc/3.3/doctrine/repository.html

Then you can reference the function.

$em = $this->getDoctrine()->getManager();
$data = $em->getRepository(EntityClassName::class)->repositoryFunctionName($paramifyouhaveany);
