[Rails] Using :include "recursively" (including the children of the child)?

[Iván Vega Rivera]

Hi,

Let's say I have the following hierarchy of tables:

Group <- parent
Location <- child of Group
School <- child of Location
Phone <- child of School

Then, if I want to do this:

Location.find(...someparms..., :include => [:schools, :group, :phones])

I get an association error (Association was not found). I guess it 
happens because AR is looking in the Location model for the Phones 
association, which only exists in the School model (I also tried 
singular, :phone).

Is there any way I can load all Phone records at once? I wouldn't mind 
using custom SQL if that's the only solution.

Thanks in advance!

Ivan V.
