can i update in one query a group of objects? i’ve something like: objs  
= Model.find(:all, :conditions =\> …)…can i do something like  
objs.update\_attribute(:active, true) ?  
i can’t do a objs.each do |obj| obj.update\_attribute  
because it’s in a script which run every 5 minutes…and N could be 1  
as could be 10000 ☹

Model.update\_all ‘active = true’, ‘your conditions’
