The model directory belongs to a software instance.

What magic were you expecting to have happen? (Rails did exactly what  
you told it to).

Don’t you want something like

format.xml { render :xml =\> @software.to\_xml( :include =\> :directories )  
}

If you want only @directories, then you should create an rxml template  
to be used under software, where you marshall the xml data is any old  
format you want.

for directory in @directories  
xml.directory do  
xml.directory\_name(directory.name)  
etc  
etc  
end  
end

I want each directory as xml, just how it is…but the associated  
“software” object, I want to include that. What you wrote initially  
looks backwards to me.

since this is requested as directories.xml

 .... \<%= directory.software.name %\>

It sounds like that’s the only way to create an index.rxml file?

I figured there would be an automatic way to map associated models to  
the default xml output.
