[Rails] actionmailer issues

[Jeffrey Moss]

You need to get used to debugging if you are ever going to make any progress 
unassisted. Try using the "console" script in the scripts directory to debug 
this. You must print the results of inspect in order to see it. Run console, 
load your model with require user, then start debugging:

user = User.find_first("id = 123") [enter]
print user.inspect [enter]
confirmation = user.confirmation.build('id' => rand(Time.now)) [enter]
print confirmation.inspect [enter]

I fixed this code for you, dont forget to call save after you "build" an 
object.

Good luck!
