Rails - Mar 2006 - new user.presentation

Hi,

I''m creating an RoR application right now and i''ve got the
following
question:

An user has one presentation.

So i''ve got an user table and in that table is an field 
fkPresentationID. Now i want to create an new user and at the same 
moment an new presentation for that user. I thought it would work with 
something like this, but it didn''t work.

@user = User.new(params[:user])
@user.presentation.new(params[:presentation])
if @user.save
    flash[:notice] = ''OK.''
    redirect_to :action => ''list''
else
    render :action => new
end

Can anyone tell me what i''m doing wrong?

Thanks in advance

I think this should be @user.presentation = Presentation.new

Hi Daan,
Not fully awake yet (still working on my first pot of coffee :) ...but I did
want to point one thing out...
You do know that the convention for this field is typically presentation_id
? If you need this field name, make sure you have this in your Presentation
model:
belongs_to :user, :foreign_key => "fkPresentationID"

@user needs to be saved before a presentation can be attched, becasue 
user needs to have a id for the presentation to recognize it.
