Named_scope returns Array -- find returns error?

Rails
1

From the documentation:

class Shirt < ActiveRecord::Base
named_scope :red, :conditions => {:color => ‘red’}
end

Unlike Shirt.find(…), however, the object returned by Shirt.red is not
an Array; it resembles the association object constructed by a has_many
declaration. For instance, you can invoke Shirt.red.find(:first),
Shirt.red.count, Shirt.red.find(:all, :conditions => {:size => ‘small’})

So Shirt.red.find(:all, …) is valid according to the docs.

I have:

class Member < ActiveRecord::Base
named_scope :active_members, :conditions => { :rcrd_status => ‘Y’ }
end

And wish to call:
Member.active_members.find(:all, :conditions => { … })

But I’m getting the error:

ArgumentError (wrong number of arguments (2 for 1)): in `find’

And I noticed Member.active_members.class.to_s returns “Array”

What gives? I can’t imagine the documentation being that wrong, so
what did I do wrong?

Can you show us the exact line that fails please with a few lines each
side, with line numbers, and the trace dump?

What happens if you use active_members without the find?

It’s a pity there’s no way to delete threads here. It turned out I had a
class method with the same name. slaps forehead. Typical. Spend
forever finding a bug, ask for help, find the answer yourself soon
after! Sorry for the noise.
