Bug Tracker Architecture

I am creating a Bug Tracker application (toy one) with DDD in mind. I have a BugRepository with methods like Add / Delete / Save and a user Repository having the same kind of methods (Actually both derive from IRepository). Now Bug has a Property called "Assigned To" which is a column in DB where the ID of the user is stored.

Now I need a method called "FindAssignee" or rather I want to know who the bug is assigned to. Where do i put that?

I was thinking that I could say --> In BugRepository add a method called "FindAssignee". But that would return a "USER" object. Is that OK? Aren't repositories for an aggregate root (Bug this case) supposed to return ONLY their entities (Bug again) ?

Solution

  • Is that OK?

    Yes.

    Aren't repositories for an aggregate root (Bug this case) supposed to return ONLY their entities (Bug again) ?

    Yes.

    But your query isn't to a aggregate root.

    Your query is against a specific Bug which has one or more Assignees.
