New Error Handling in Rails 2.0
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:
class AccountsController
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
