Ruby on Rails - how to display as xml models with has_many associations

Question

I have a ruby ​​on rails application that has two models - sheets and sub_tests. Ltest has an association ' has_many' with sub_tests. The show method for ltests has the following.

respond_to do |format|
  format.html # show.html.erb
  format.xml  { render :xml => @ltest }
end

This creates an ltest object. However, sub_tests owned by ltest are not displayed.

How can i do this?

<ltest>
....
   <sub_test>
   ...
   </sub_test>
   <sub_test>
   ...
   </sub_test>
</ltest>

I tried to do this with the following look:

But this generates two XML documents, not one with sub_tests built into the libraries.

Any suggestions on how I can do this?
