Rails 2.0 has added in a very cool way to trap errors without a bunch of messy nested rescue blocks or case statements.
The ticket that added all the magic is here. And it couldn't come too soon as I immediately had a project that needed it. Check out what I was looking at doing:
and now with the new exception handling:
class AccountsController :overdrawn rescue_from Account::Suspended, :with => :suspended rescue_from ActiveRecord::RecordNotFound, :with => :not_found protected def overdrawn flash[:error] = "Sorry the account this transaction would make this account overdrawn" redirect_to account_path(params[:account]) end def suspended flash[:error] = "Sorry the account you are trying to use has been suspended, please contact customer services" redirect_to account_path(params[:account]) end def not_found flash[:error] = "No such account could be found" redirect_to user_path(current_user) end end
woohoo!! Much cleaner and more descriptive of my intentions
