DDD Symfony / Doctrine library - Security User needs UserInterface

What the title basically means is this:

tldr; My User Domain model, which should not have any relation to the Application layer, needs the UserInterface (a Symfony class) for Symfony Security to work.

My setup is as follows:

app/
...
src/
vendor/

"app" contains all the pure Symfony code that uses all the "Domain" related code from "src"

"src" contains a Domain that has a structure like so:

DomainName/Application
DomainName/Domain
DomainName/Infrastructure

The "User" model (plain old php object) defined within DomainName/Domain SHOULD NOT implement/extend code from the Application layer. But I can't get it to work. I have looked into extending and providing a "different" User model (from within "app") and mappedSuperclasses of Doctrine, but my model has too many relations for that to work.

Is this setup even possible or should I accept this is the only way to go? :(

NB: I hope it is kinda clear what I'm trying to achieve, it's difficult to explain.

Full example layout:

app/

config/security.yaml
    security:
      ...
      providers:
        app_user_provider:
          entity:
            class: DomainName\Domain\User

src/DomainName/Domain/User.php
    - Nothing special, id, uuid, etc

src/DomainName/Domain/Repository/UserRepository.php
    - This is an interface, because the domain does not contain the implementation

src/DomainName/Infrastructure/Persistence/Doctrine/Dbal/UserDbalRepository.php
    - This implements the UserRepository, and the UserRepository will always be injected within "app"

src/DomainName/Infrastructure/Persistence/Doctrine/ORM/User.orm.yml
    - This is the mapping ORM file for the Entity
Solution

  • A bit old topic, but for other people who will face similiar issue I had exactly same case in my current project, and I solved it by creating Domain User Model and in Infrastructure I have created SecurityUser model, with dependency of my User model from Domain, so I was able to use my Domain UserRepository eg. in custom user provider from which I was returnig SecurityUser, with injected Domain User fetched from repository.
