Rails - Aug 2010 - find does not raise exception

Hi
   I have the code

  def index
    @messages = message_thread.messages
  end

private

  def message_thread
    begin
      current_user.message_threads.find(params[:thread_id])
    rescue ActiveRecord::RecordNotFound
      logger.warn "No permission or thread_id nil"
      render :file => "#{RAILS_ROOT}/public/404.html"
    end
  end


    And even if params[:id] does not have any values I dont get any
exception . I can''t figureout why. Please help

Thanks

The problem is here:

>      logger.warn "No permission or thread_id nil"
>      render :file => "#{RAILS_ROOT}/public/404.html"
>    end
>  end
>

You have a rescue statement which is overriding the exception:
current_user.message_threads.find(params[:thread_id]) rescue
ActiveRecord::RecordNotFound

 remove the rescue first you will see an exception.

Hi Edmond
Thanks for your reply. The problem is not that. Even it enters in 
rescue, it does not render :file =>
"#{RAILS_ROOT}/public/404.html". But
it continues execution and I get problem at @messages = 
message_thread.messages

  as nil.messages


Thanks
Tom
