Polymorphic associations

[Thomas]

It seems to have been asked before, but I can't find a definitive
answer.

I have a model, address:

class Address < ActiveRecord::Base
belongs_to :addressable, :polymorphic => true
end

with a factory:

Factory.define :address do |a|
a.line_one { Random.address_line_1 }
a.line_two { Random.address_line_2 }
...
end

I have another model, company:

class Company < ActiveRecord::Base
has_one :address, :as => "addressable", :dependent => :delete
end

Factory.define :company do |c|
c.name { Random.firstname + "'s
Company" }
c.email { Random.firstname.downcase +
"com...@example.com" }
c.association :address
...
end

The problem comes in using the company factory. I happen to have a not
null constraint in my database, so doing Factory(:company) raises this
exception:

>> Factory.build(:company)
ActiveRecord::StatementInvalid: Mysql::Error: Column
'addressable_type' cannot be null: INSERT INTO `addresses` (`city`,
`line_two`, `updated_at`, `updated_by_id`, `addressable_type`,
`zip_code`, `addressable_id`, `line_one`, `created_by_id`, `state`,
`created_at`) VALUES('Umnkomaaz', 'Fl 613', '2009-11-19 03:32:43',
NULL, NULL, '55000', NULL, '27452 Oak Rd', NULL, 'AR', '2009-11-19
03:32:43')

Factory Girl doesn't set the id or type field on the polymorphic
association. Factory.build(:company) fails similarly, factory girl
tries to save the address for some reason.

Anyone have any ideas? Thanks!

I wrote a simple post about Polymorphic associations in factory_girl,
it should help you somehow, see http://blog.wangyaodi.com/2009/11/03/polymorphic-association-in-factory_girl/

You could use an after_create callback to add the address.

For example:

Factory.define :company do |c|
c.name 'your mom inc'
c.email 'yourmo...@lolyourmom.com'
c.after_create {|company|
Factory(:address, :addressable => :company)
}
end

Yeah, upgrading to FG 1.2.3 (I was at the previous version) and using
after_create works best.

Thanks!
