Rails - Jun 2006 - Newbie: Help Please - Model Validation Error

Hi,

I''d be grateful for your help.

I get the error (see below) everytime I add the
following into a newly generated (via scaffold) model
class:

validates_presence_of :myname, :mymessage, :mytel

Without it, I can insert records into my database.
With it, I get the error :(

ERROR>>

 ArgumentError in AdminController#create 

wrong number of arguments (1 for 0)

RAILS_ROOT: script/../config/..

> validates_presence_of :myname, :mymessage, :mytel
Have you tried putting those on their own lines?

validates_presence_of :myname
validates_presence_of :mymessage
validates_presence_of :mytel

?

think of validates_presence_of like a javascript function, you''re 
passing vars to it in a specific order.

validates_presence_of(object,optionalthingslikemessageandifblocks)
