Dynamically Adding Serialization Groups to Properties in Symfony 6.4 Using Traits

30 Views Asked by At

I'm working with Symfony 6.4 and have encountered a scenario where I need to dynamically assign serialization groups to entity properties defined in a trait. The goal is to use this trait across several entities (e.g., User, Profile) without losing the benefit of defining serialization groups directly within the trait's properties.

Each of my entities have their own Serialization Groups (User:read, User:write, User:read:collection, Profile:read...)

Here's the trait I'm using:

<?php

namespace App\Entity\Definition;

use DateTime;
use Doctrine\ORM\Mapping as ORM;

trait LifeCycleTrait
{

    #[ApiFilter(DateFilter::class)]
    #[ApiFilter(OrderFilter::class)]
    #[ORM\Column(type: 'datetimetz', options: ['default' => 'CURRENT_TIMESTAMP'])]
    protected ?DateTime $createdAt = null;

    #[ApiFilter(DateFilter::class)]
    #[ApiFilter(OrderFilter::class)]
    #[ORM\Column(type: 'datetimetz', options: ['default' => 'CURRENT_TIMESTAMP'])]
    protected ?DateTime $updatedAt = null;
    ...
}

Currently, to assign serialization groups to these properties in implementing classes, I have to override them like so, which defeats the purpose of using the trait:


class User {
    use LifeCycleTrait;

    #[Groups(['User:read'])]
    #[ApiFilter(DateFilter::class)]
    #[ApiFilter(OrderFilter::class)]
    #[ORM\Column(type: 'datetimetz')]
    protected ?DateTime $createdAt = null;

    #[Groups(['User:read'])]
    #[ApiFilter(DateFilter::class)]
    #[ApiFilter(OrderFilter::class)]
    #[ORM\Column(type: 'datetimetz')]
    protected ?DateTime $updatedAt = null;
}

I'm looking for a way to dynamically add serialization groups to these properties without having to override them in each implementing class. For context, I've successfully used the loadClassMetadata event for Doctrine to add field mappings manually for a Doctrine entity, but I'm unsure how to approach this for serialization groups.

Is there a way in Symfony, possibly using events or another mechanism, to dynamically assign serialization groups to trait properties during or before serialization?
