I want to have a parent model that I can add child objects (via a  
has\_many association) using the rails 2.3 nested form syntax. However,  
it seems like rails throws an error during validation of the parent  
model if I have a validates\_presence\_of :parent\_id defined in the child  
model.

Is the only solution to this to remove the validates\_presence\_of  
:parent\_id? This seems like a hack-ish workaround.
