It sounds like you're using scaffolding, which had a problem regarding 
this in Rails 0.8.5. You can fix it manually by doing something like:

<%= form("house", :action => url_for(:action => "save_house")) %>

...if my guess at what your problem is have any grounding in reality. 
This problem is fixed in the very forthcoming (and massive) Rails 0.9 
upgrade.

Amenities.find accepts and array and will return a such. 
@house.amenities.<< does the same and creates a link between the house 
and amenity for each of the records found.
