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

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

The problem is here:

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

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
