 scope :search, lambda{|query| where(["name LIKE ?", "%#{query}%"])}

You can use rails' update_all method. See here for a description: http://apidock.com/rails/ActiveRecord/Relation/update_all

EDIT: It's part of the Relation class, so you may call this on scopes (It doesn't say that explicit in the documentation)

EDIT2: It works very much like destroy_all which may also be called on scopes (Relation)
