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.
