This should be straightforward but a search hasn’t helped:

I want to convert this:  
\<% for post in @posts %\>

\<%= link\_to "#{post.title}" %\>

posted by \<%= link\_to "#{post.person.name}" %\>
  

\<%= h(post.body) %\>

  

\<% end %\>

into THIS:

\<% for post in @posts %\>  
\<%= render :partial =\> ‘postblock’%  
\<% end %\>

but just moving the PostBlock div into \_postblock.rhtml gives an invalid  
action for “post.” How can I cleanly separate this? I’ve also tried  
using :collection =\> @posts but the documentation on :collection is very  
poor. Thanks!

It was a naming convention problem. Since the passed object is  
automagically named the same thing as the partial, penaming the partial  
to “\_post.rhtml” works:

\<%= render :partial =\> ‘post’, :collection =\> @posts %\>
