Question

I just want to flash an notice/error if the message is/isn’t saved, without any redirect, how can I have no redirect:

  respond_to do |format|
  if @message.save
    format.html { redirect_to request.referer, :notice => 'Message sent!' } #dont want redirect
  else
    # error message here
  end

Answer 1

Use flash.now:

if @message.save
  flash.now[:notice] = 'Message sent!'
else
  flash.now[:alert] = 'Error while sending message!'
end

respond_to do |format|
  format.html { # blahblah render }
end
