Render cached action of another controller inside erb template

Question

Hi,

I want to render action inside my erb template.

<div>
  <%= render :controller => :tags, :action => :tag_cloud %>
</div>

This block throws exception: undefined method `formats' for nil:NilClass

Also I want to tag_cloud action to be rendered from cache. Is that possible?

Answer 1

Just remind that render :action does not run the tags controller, it just renders the tag_cloud erb with the variables you have defined in your current controller. So you have to define in your controller all the instance variables you need in your template, including the one on which the formats method is called.
