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”

HTH,

@presentation.valid?  
if @presentation.valid? and @user.valid?  
@presentation.save  
@user.presentation = @presentation  
@user.lastlogin = Time.now  
@user.save  
flash[:notice] = ‘Ok’  
redirect\_to :action =\> ‘list’  
else  
render :action =\> ‘new’  
end
