Question

This is my session’s controller code

  def create
    user = User.authenticate(params[:login], params[:password])
    if user
      session[:user_id] = user.id
      redirect_to_target_or_default root_url, :notice => "Logged in successfully."
    else
      flash.now[:alert] = "Invalid login or password."
      render :action => 'new'
    end
  end

I need a div id="welcomebuttons" located in layouts/application.html.erb to display when the user is not in session (logged out) but disappear completely and remain hidden when the user is logged in. I tried adding javascript:hideDiv_welcomebuttons() to the if user but of course that didn’t work.

Could anyone help?

in application layout

<% if session[:user_id].nil? %>
  <div id="welcomebuttons">
  </div>
<% end %>
