How Select just some columns ?

Hi,

if I do:
user = User.find :all
render :xml => user.to_xml

I obviously get the user records whith ALL the columns (name, surname,
tel, email, ...)

depending on what you're doing, either use the :select option on the
call to find or the :only/:except options on to_xml may be what you
want.

':select' is perfect:

users = User.find(:all, :select = 'email')

I overlooked it in RoR api.
Thank you !
