Rails - Dec 2008 - Problem with associations that could be null sometimes

Hi Everybody,

I''m developing a little task management system with a Task model that
belongs to Users and Projects.

The problem is that sometimes a task won''t belongs to an user AND a
project. It will be possible to add a task to a project without
delegate it to any user. In a similar way, it will be possible for
users to create a new task without assigning it to any project.

So, my question is: Can I simply create the belongs_to associations
for the Task model and leave the foreign_ids empty in the cases where
the task doesn''t have an user or a project? Is there a better
solution?

Thanks.
