Forum: Ruby on Rails Is a global set of named_scope scopes a bad idea? If not, is it possible?

I've noticed that several of my models contain the same set of
named_scopes (ones for active, various access levels, etc.).  I was
thinking to avoid the duplication I'd try to pull that coat into a
common file either included or extended from within my models.

I created a module, but that didn't seem to work w/ errors trying to
use named_scope.  I create a "base" model and made the other models
child classes to it, but Rails looked for a bases table, which makes
sense, but unfortunately the table doesn't exist.

Is this possible or am I stuck duplicating the named_scopes across all
of my models?

When you tried using a module, did you try it like this? ie. putting the
calls to named_scope inside self.included ?

module MyScopes
  def self.included(base)
    base.send :named_scope, ... params ...


Another option might be to make a plugin with your named scopes in them.

No, I didn't try that but that worked perfectly.  Thanks for the tip.
