Answer 1

I am assuming you have a rental object, for which you show the form, I assume it is an instance variable @rental, furthermore I assume that inside your Rental class there is the following relation

class Rental

  belongs_to :user

end

Then you could just write the following:

f.select :user_id, [[@rental.user.user_name, @rental.user.id]]

Hope this helps.

On a related but less important note: it is really weird to have a column called user_name for a user: I would call that column just name, since it is part of a user anyway.
