Pass a variable into a partial, rails 3?

Try this:

<% @posts.each do |post| %>
  <%= render 'middle', :post => post %>
<% end %>

Like this you'll have a local variable post available within the partial.

Give it to the partial as a local variable

<%= render :partial => 'middle', :locals => { :post => post } %>

Of course, rails also has a shortcut for rendering collections:

<%= render :partial => 'post', :collection => @posts %>

In this case it will call the partial post for every post with a local variable 'post'

You can even render a spacer template between each post:

<%= render :partial => 'post', :collection => @posts, :spacer_template => 'post_divider' %>

<% @posts.each do |post| %>
  <% render middle, :post => post %>
<% end %>

You can now access post as the local variable post in the partial

Replace <%= render middle %> with <%= render middle, :post => post %>. Then in your middle partial, you can access the post variable.
