Refactoring module
Dear all
Please see the following module, In module SX3 SX4 and SX5 have similar
class Tasklist, but inherit from different class.
I will use the following code to connect to different data sources
RemoteSX3Model.establish_connection sx3_hash
RemoteSX4Model.establish_connection sx4_hash
RemoteSX5Model.establish_connection sx5_hash
How can I refactor my code in module to look simpler? Thank you

has_and_belongs_to_many on legacy DB
I am working with mapping ActiveRecord onto a legacy database. All is going
well (using set_table_name, set_primary_key, etc), but I can''t get my

[AR] #{id} namespace visibility used in finder_sql
Dears,
[Rails 1.0.0]
I''m working with a legacy schema, and around my 20+ models i''ve used

They are based on a finder_sql doing some dirty sql and using #{id}
from the ''pivot'' model for extracting data in other tables.

ActiveRecord method so I would like to reference the table name with
self.table_name or something...

has_one mapping with arbitrary right and left hand side keys
I have two tables:
table_1:
tab1_id,
other_id
table_2:
id,
tab2_id,
something_else
I would like to specify a has_one mapping from table_1 to table_2 but
specifying that the join is based on (table_2.tab2_id =
table_1.other_id).
I am half way there with:
class Table1 < ActiveRecord::Base
set_table_name "table_1"
set_primary_key "tab1_id"
has_one :Table2, :class_name
