render :collection and :partial

Does the :collection option on render only work with :partials? Or can
I call render :collection directly from a controller against a normal
(non-partial) template? I couldn't get it to work but maybe I am
missing something.

Rendering collections is only meant to be done with partials.

Pito, we'd need to see some code to be more helpful.

Try changing the name of the partial to match the model / variable
names.

You can streamline your render partial calls by using instance
variable names that match your class and partial name

e.g. <%= render :partial => @posts %> would render the collection
@posts in a partial called _post.html.erb (Rails 2.0.2) ( i think)

If you wanted to render a colleciton in a normal template either
create the partial call within it or use the each method to iterate
the collection. e.g.
@posts.each do |post|
....
end

With more AJAX stuff it makes sense to use partials more often so you
can reload sections of your view easily from rjs.
