Problem Description

Currently, the indexBy attribute in Doctrine's OneToMany association is not supported by AssociationOverride. This limitation prevents developers from overriding the indexBy configuration in subclasses when extending a mapped superclass.

Detailed Example

Consider the following XML mapping in a mapped superclass:

<one-to-many
    field="channelPricings"
    target-entity="Sylius\Component\Core\Model\ChannelPricingInterface"
    mapped-by="productVariant"
    orphan-removal="true"
    index-by="channelCode"
>
    <order-by>
        <order-by-field name="id" />
    </order-by>

    <cascade>
        <cascade-all/>
    </cascade>
</one-to-many>

In this example, the channelPricings collection is indexed by channelCode.
However, when extending this mapped superclass, there is no straightforward way to override the indexBy attribute using AssociationOverride.

To get around the problem, I completely redefined the relationship by specifying a different indexBy.

    #[ORM\OneToMany(
        mappedBy: 'productVariant',
        targetEntity: ChannelPricingInterface::class,
        cascade: ['all'],
        orphanRemoval: true,
        indexBy: 'id',
    )]
    #[ORM\OrderBy(['id' => 'ASC'])]
    protected $channelPricings;
