How can I use a link\_to that will send multi-level params? I need to be  
able to use the following in the controller:

params[:sales\_order][:id]

Here’s the link\_to I currently have:

link\_to sales\_order.id.to\_s, :action =\> ‘show’, :id =\> sales\_order.id

But that just gives me this in the controller:

params[:id]

Is it possible to do what I’m wanting?

Thanks!

Allright, I think I figured out how to do this. Maybe it can help  
someone else:

link\_to sales\_order.id.to\_s, :action =\> ‘show’, :sales\_order =\> {:id  
=\> sales\_order.id}
