I am a bit confused when coming from layout and partials.
To start of I have a file called application.html.erb which has my
layout such has follow
<html>
<head>
<body>
<%= render ''layouts/footer'' %>
</body
</html>
This call a new file _footer.html.erb
This file his has follow
<footer class="footer">
<nav>
<%= render "pages/link" %>
<ol class="footer_pages">
</ol>
</nav>
</footer>
Which calls a partial in the folder Pages which his a resources and has
_link.html.erb and contains the follow
<li>
<%= @pages.each do |page| %>
<%= page.name %>
<% end %>
</li>
Now the issues is @pages.each his nil and I understand the caller will
initiate the @pages = Page.all but the caller is who??
I try application and inserting it and doesnt see it, What i am doing
wrong?

Also have a look at the Rails Guide on Layouts and Rendering (I seem to remember suggesting this before), section 3.4.4 details how to pass local variables to partials. But read and understand the rest also. Have you finished working through railstutorial.org yet? I strongly suggest working through that before doing more on your own app. I seem to remember suggesting that before also.

I did set it up in the controller action of which one - controller/application -- prob with this is there is no action define - controller/pages -- in which actions, i try show, index doesn''t see it - controller/customer -- don''t even understand why it would be in customer - controller/sessions -- same has customer irrelevant it because i am calling from the footer which is located in the application -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Have you really worked right through railstutorial.org? If so then I think you need to go back to the beginning and start again, making sure you understand every concept and every line of code.
