You are my personal hero, today. Thank you so much for helping out on
this thread. It works.

Ok, so this seems to work
1) Create dynamic classes from a list (some rework on getting that from
tables automatically needed)
2) Instantiate those objects
A minor error pops up now.
The tables exist, as do the fields.
However, with:
service = Services.new(:portID => 333, :method => "PUT")

That makes sense, thought it might be a scope problem.
Thank you.

I have a scenario where I need to dynamically create classes from
existing application (external to app) databases, to pull data for
reports.
# Table definitions
APP_TABLES = %w(#list of tables for a given app - I'm sure I could
query this on a simple connect. But let's stick to this for now.)
Thanks. It does seem like multiple DBs and migrations do not necessarily
play well.
Would be interesting to see a recipe for this somewhere.

I have a Rails reporting application that will generate reports for
other Rails applications.
As such I need to import legacy databases, but might also over time,
change them.
How do I handle migrations with having, and connecting to, x number of
databases?
I've defined the 'other' databases con
class Pair < ActiveRecord::Base
belongs_to :flag
belongs_to :item, :class_name => 'Item', :foreign_key => 'item_1',
:validate => true
belongs_to :item, :class_name => 'Item', :foreign_key => 'item_2',
:validate => true
end
seems to fix the problem.

I have a very simple pairing scenario that links a pair to two items
(cross-comparison and rating).
My problem is that on insertion of the pair I get an
AssociationTypeMismatch error, that I haven't seen before.

I have the following model layout:
class List < ActiveRecord::Base
has_many :subscribers, :through => :list_subscribers
has_many :list_subscribers
end
class Subscriber < ActiveRecord::Base
has_many :lists
has_many :lists, :through => :list_subscribers
end
class ListSubscriber< ActiveRecord::Base
