DQL - leftJoin() error: Expected Literal, got 'JOIN' - symfony

Question

This code:
$builder->select('p')
->from('ProProposalBundle:Proposal', 'p')
->leftJoin('ProProposalBundle:Proposal:Vote', 'v')
->leftJoin('ProUserBundle:User', 'u')
->andWhere('v.proposal = p')
->andWhere('v.user = u')
->andWhere('v.decision = "in_favor" OR v.decision = "against"')
->andWhere('u = :user')
->setParameter('user', $options['user'])
->andWhere('p.community = :community')
->setParameter('community', $community)
->andWhere('p.archived = :archived')
->setParameter('archived', $options['archived'])
->leftJoin('p.convocation', 'c')
->andWhere("p.convocation IS NULL OR c.status = '" . Convocation::STATUS_PENDING . "'");
return $builder->getQuery()->execute();
is returning an error:
[Syntax Error] line 0, col 106: Error: Expected Literal, got 'JOIN'
This is the formed query:
SELECT p FROM ProProposalBundle:Proposal p LEFT JOIN ProProposalBundle:Proposal:Vote v LEFT JOIN ProUserBundle:User u LEFT JOIN p.convocation c WHERE v.proposal = p AND v.user = u AND (v.decision = "in_favor" OR v.decision = "against") AND u = :user AND p.community = :community AND (p.convocation IS NULL OR c.status = 'pending') ORDER BY p.created desc
LEFT JOIN is missing the ON or WITH condition. The question is: what am I doing wrong with DQL query? Am I wrong with leftJoin() method?

Answer 1

Doctrine ORM needs you to tell which relation is joined, not the entity itself (you did it well with p.convocation) :
$builder->select('p')
->from('ProProposalBundle:Proposal', 'p')
->leftJoin('ProProposalBundle:Proposal\Vote', 'v', 'WITH', 'v.proposal = p AND v.user = :user AND (v.decision = :in_favor OR v.decision = :against)')
->setParameter('user', $options['user'])
->setParameter('in_favor', 'in_favor')
->setParameter('against', 'against')
->andWhere('p.community = :community')
->setParameter('community', $community)
->andWhere('p.archived = :archived')
->setParameter('archived', $options['archived'])
->leftJoin('p.convocation', 'c')
->andWhere("p.convocation IS NULL OR c.status = :pending")
->setParameter('pending', Convocation::STATUS_PENDING);
return $builder->getQuery()->execute();
edit: I inversed Vote relation as you commented and removed useless WHERE clauses (Doctrine automatically resolves JOIN ON clause. I also transferred some WHERE clauses about joins in the optional params (WITH in DQL).
edit2: Without relation between Proposal and Vote, not sure it works.
edit3: Best practice is to use setParameter for all values in WHERE clauses.
