Returns an anonymous scope.
posts = Post.scoped posts.size # Fires "select count(*) from posts" and returns the count posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects fruits = Fruit.scoped fruits = fruits.where(:colour => 'red') if options[:red_only] fruits = fruits.limit(10) if limited?
Anonymous scopes tend to be useful when procedurally generating complex queries, where passing intermediate values (scopes) around as first-class objects is convenient.
You can define a scope that applies to all finders using ActiveRecord::Base.default_scope.
