Extend ApplicationUser with Domain entities relationship

Hello,

I was wondering how one could extend the ApplicationUser the cleanest way possible if I need a one-to-many relationship between ApplicationUser and one entity from my Domain project. Should I just move ApplicationUser to my Domain model? Right now, I cannot do it since my domain model has no idea about ApplicationUser.

Then you already have multiple options listed above to accomplish that.

The easiest and quickest way is to simply have Entity inherit from AuditableEntity. This way the CreatedBy property will be populated with the current user’s ID automatically when Entity is added to the Db.

When retrieving Entity from the Db, just inject ICurrentUserService into your Get Entity handler and select where CreatedBy == _currentUserService.UserId.

E.e.

public class GetEntityQueryHandler : IRequestHandler<GetEntityQuery, EntityDto>
{
    private readonly IApplicationDbContext _context;
    private readonly IMapper _mapper;
    private readonly ICurrentUserService _currentUserService;

    public GetEntityQueryHandler(IApplicationDbContext context,
        ICurrentUserService currentUserService)
    {
        _context = context;
        _currentUserService = currentUserService;
    }

    public async Task<EntityDto> Handle(GetEntityQuery request, CancellationToken cancellationToken)
    {
        var entity = _context.Entity
            .FirstOrDefaultAsync(i => i.CreatedBy == _currentUserService.UserId);

        return _mapper.Map<Entity, EntityDto>(entity);
    }
}

In any case, your issue is a software design issue and not an issue related to this project. The above comments more than cover the issue you described. If you need further help, I suggest you post a question on StackOverflow (where questions like this belong).

Good luck.
