I think you should be able to do:

<%= f.select :user_id, User.find(f.object.user_id).collect {|t| [t.user_name, t.id]} %>

This does seem a little odd to me though. I'd have thought either:

• Your object has a proper association to the relevant user, in which case you should be able to do f.object.user.user_name and f.object.user.id.
• If you genuinely want the currently logged in user, you should probably be asking your authentication framework/code for the reference. E.g. if you were using Devise, it would be current_user.

As an aside, I don't really understand why you want a select list just containing the current user - is that definitely what you're trying to achieve, or have I misunderstood?
