Ruby on Rails

Something you think should be happening isn't happening. I don't see
any debugging code in your files.

Are you using your log file to verify the parameters being passed in
from your form and review the queries being executed?

You might want to avoid mass assignment for security reasons and to
give more control.
For example, in your controller,

:stuff = { :authnum => params[:contract][:authnum],
:st_date => params[:contract][:st_date],
:end_date => params[:contract][:end_date] }
logger.debug("------------------------ stuff #{stuff.inspect}")
@contract = Contract.new(stuff)
