I am trying to design my ruby on rails app at the moment. I created views/layouts/posts.html.erb which styled my PostsController‘s views.

I want to add a main bar that is always at the top of the page no matter what view the user is looking at. I thought this was what the views/layouts/application.html.erb was for.

This seems to agree with me:

  • The entire Rails application (all views of all controllers) will
    use this layout:

    views/layouts/application.rhtml

  • All views within a single controller will use this layout. For
    example, the layout for
    weclome_controller.rb will use this
    layout. Notice, the ‘_controller’ is
    left off for the layout:

    views/layouts/welcome.rhtml

What am I doing wrong?

Here is what I have in the body of my application.html.erb

  <div id="top-bar">
      <div id="user_nav">
        <% if current_user %>
          <%= link_to "My Profile", current_user %>
          <%= link_to "Logout", logout_path %>
        <% else %>
          <%= link_to "Register", new_user_path %>
          <%= link_to "Login", login_path %>
        <% end %>
      </div>
    </div>
    <%= yield %>

    Both your layouts, application.html.erb and posts.html.erb should render the main bar as a partial:

    <%= render :partial => 'layouts/main_bar' %>

    All layouts contain the <html> element that wraps your page; you don’t have one layout wrapping around the other.
