Symfony2 Doctrine oneToMany orderBy multiple columns

Question

我有这样的代码（.yml）：

oneToMany:
        products:
            targetEntity: SMS\Bundle\SwiadczeniaPlatne\Domain\Zlecenie\Produkt
            mappedBy: zlecenie
            cascade: [persist, remove]
            indexBy: id
            orphanRemoval: true
            orderBy: { patient: ASC, contract: ASC }

患者和合同是对象。我想通过patient.name和contract.name对产品进行排序。我怎么能这样做？

Answer 1

格式错误：

oneToMany:
        products:
            targetEntity: SMS\Bundle\SwiadczeniaPlatne\Domain\Zlecenie\Produkt
            mappedBy: zlecenie
            cascade: [persist, remove]
            indexBy: id
            orphanRemoval: true
            orderBy: 
                patient: ASC
                contract: ASC
