ruby on rails - How can I lock a model's associated collection? -

i have

class foo   has_many :widgets end

there's place want pull widgets locked select. so, want equivalent of:

@widgets_to_work_with = widget.find_all_by_foo_id(@foo.id, :lock => true)

with nicer code, like:

@widgets_to_work_with = @foo.widgets(:lock => true)

what's best way this?

you redefine method widgets in foo activerecord or , safer ,add method a.e.

# in foo.rb #... def self.locked_widgets   widget.find_all_by_foo_id(self.id, :lock => true) end

hope usefull
