def view\_history  
@posts = Post.search\_by\_requirement\_id(params[:id], params[:page])  
end

view\_history.html.erb

\<%= render :partial =\> :threads, :collection =\> @posts %\>

The @posts in view\_history doesn’t seem to make it to the  
\_threads.html.erb

Help!!

Thanks! =)

I believe there is a naming convention to follow if you’re using  
the :collection option. if your collection is called @posts your  
partial should be called the singular (\_post.html.erb).

Try then

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

I’m sure there are other (better) ways to do this… I’ve had success  
following this convention tho.
