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)
