ok, well i have os\_hardware\_combos.send(“platform\_id”) which returns 1  
and i have Platforms.find(1)  
which returns a value i want  
but if i do Platforms.find(os\_hardware\_combos.send(“platform\_id”)) it  
says,  
no id supplied to the find method

The only thing I can think of would be the 1 that is returned is not  
numeric? Although this didn’t seem very ruby like.

Any help?

This is really an activerecord question, but I’ll give it a shot. You  
should try doing it like  
Platforms.find(:first, :id =\> os\_hardware\_combos.platform\_id)

Actually, if os\_hardward\_combos is an instance of AR, you should just  
do os\_hardware\_combos.platform
