Nested :throughs

Why not just have an extra field in the Task model called completed
(boolean). Next, create a method in the Task model that looks something
like this:

def tasks_completed_by_user(user)
  find(:all, :conditions => {"user_id = '#{user}'", "completed = '1'")
end

That would give you a collection of Tasks that are marked completed.

Now I am a ROR newbie so the code above may need some tweaking... but
you get the idea.

Thanks for the replies Mark and Melvin.

Since the tasks can indirectly belong to many users at once I couldn't
simply add a completed boolean to that class. ("Run a mile under 6
minutes" might be completed by Jeremy but not yet by Alex).

I ended up adding this method to my user model:

def completed_tasks_in_current_award
    tasks = []
    completed_tasks.each do |ct|
      if ct.task.task_group.award == award
        tasks << ct.task
      end
    end
    tasks
end

I'm guessing there might be a way to do it with more code - but this
will suffice for now.
