Import breaks when not using default primary key
Reported by DaniSchumacher | June 17th, 2009 @ 09:04 AM
I have a model where the primary key field is NOT "id". I work on MySQL tables that have been there before me.
class Buy < ActiveRecord::Base
set_table_name "BUY"
set_primary_key "buy_no"
end
When I try to import an Array of new Buys i get an error :
/usr/lib/ruby/gems/1.8/gems/activerecord-2.1.2/lib/active_record/attribute_methods.rb:251:in
method_missing': undefined
methodbuy_no_before_type_cast' for #<Buy:0xb70739d0>
(NoMethodError)

from /usr/lib/ruby/gems/1.8/gems/ar-extensions-0.9.1/lib/ar-extensions/import.rb:168:in `import'
the methods _before_type_cast only exist for 'ordinary'
attributes
what should I do ?

ActiveRecord::Extension (aka ar-extensions) is a plugin to extend and
enhance the functionality of ActiveRecord. It starts by adding better
find support for ActiveRecord. It then adds mass data import
capabilities which are highly efficient and lastly it supports to_csv
functionality.
It also introduces a cool concept of creating easily extendable pieces
of ActiveRecord functionality, so developers don't have to understand
ActiveRecord internals or have the fear of breaking ActiveRecord
itself.
