I am using transaction as :
Merchant.transaction do @merchant.save! end
Now, how can I trap the exception and show in a user friendly way if the save fails. I need to show signup again if save fails, and go to 'profile' if save is a success. How can I do that ?
rescue that exception...
begin Merchant.transaction do @merchant.save! end rescue WhateverTheExceptionThrownNameIsHere redirect_to '/doh_an_error' # or set flash[:error] or a add an error or something else end
