I'm new to named_scope so bear with me if this is dumb.
I have created two named scopes both using lambda to pass in
arguments. One passes in a single argument and works great the other
passes in two arguments and doesn't work and gives me this error:
undefined method `last_reference' for #<Class:0x4464cb4>
vendor/rails/activerecord/lib/active_record/base.rb:1833:in
`method_missing_without_paginate'
/opt/ruby-enterprise-1.8.6-20090201/lib/ruby/gems/1.8/gems/mislav-
will_paginate-2.3.8/lib/will_paginate/finder.rb:170:in
`method_missing'

`with_scope'
(__DELEGATION__):2:in `__send__'
(__DELEGATION__):2:in `with_scope'
app/controllers/orders_controller.rb:23:in `show'
The two named_scopes:
class OrderTrack < ActiveRecord::Base
named_scope :one, lambda {|id,account_id| {:conditions => ["id = ?
and account_id = ?",id,account_id]}}
named_scope :all, lambda {|account_id| {:conditions =>
["account_id = ?",account_id]}}
end
I believe I need to use lambda to pass in arguments. The
named_scope :all works great and ends up doing an sql query like:
SELECT * FROM `order_tracks` WHERE (account_id = 344)
But the single one that I want to end up doing something like:
SELECT * FROM `order_tracks` WHERE (id = 3 and account_id = 344)
doesn't want to work.
This is soft of a contrived example, but I'm just trying to see if I
understand this stuff.
Thanks.
