我一直在尋找一段時間，似乎無法弄清楚是什麼造成這種情況，我有一個模型工作節省志願者和他的家庭和工作地址。我改變了一些東西（似乎無法弄清楚我的生活），現在地址沒有被設置。錯誤的訂單保存模型導軌
這是我的主要型號：
class HumanVolunteer < ActiveRecord::Base
has_one :primaryPhone, :class_name => "PhoneNumber", :foreign_key => "id", :primary_key => "phone_id"
has_one :primaryEmail, :class_name => "Email", :foreign_key => "id", :primary_key => "email_id"
has_one :work_adr, :class_name => "Address", :foreign_key => "id", :primary_key => "workaddressid"
has_one :home_adr, :class_name => "Address", :foreign_key => "id", :primary_key => "homeaddressid"
attr_accessible :firstName, :lastName, :homeaddressid, :notes, :status, :workaddressid, :home_adr, :work_adr,
:primaryPhone, :primaryEmail, :home_adr_attributes, :work_adr_attributes, :primaryPhone_attributes,
:primaryEmail_attributes
accepts_nested_attributes_for :home_adr
accepts_nested_attributes_for :work_adr
accepts_nested_attributes_for :primaryPhone
accepts_nested_attributes_for :primaryEmail
end
和地址型號：
class Address < ActiveRecord::Base
attr_accessible :city, :line1, :line2, :notes, :state, :zipcode
belongs_to :human_volunteer
end

我可以看到什麼我認爲這個問題通過查看日誌，人類志願者首先得到保存，使用地址碼的空值s，然後地址被保存（也與電話號碼和電子郵件模型相同的問題，它們與地址設置相同），然後地址被保存，然後人類志願者不會再次用新值更新：

我能回頭到日誌中，找到一個工作，而human_volunteer是最後一件事插入。它首先插入地址，電子郵件，電話，然後在插入志願者時使用這些ID。
編輯：我也可以報告，我沒有得到任何錯誤，一切都經過，只是數據沒有連接。
任何想法可能導致訂單的變化？我看不到我改變了任何影響這一點的事情。
更新：我試圖改變HAS_ONE線和能夠至少產生一個錯誤（更好或更差），當我cahnged行到：
has_one :workaddress, :class_name => "Address", :foreign_key => "id", :primary_key => "workaddress"
has_one :homeaddress, :class_name => "Address", :foreign_key => "id", :primary_key => "homeaddress"
它嘗試使用addressid 1每次我也得到
ActiveRecord::RecordNotUnique (PG::Error: ERROR: duplicate key value violates unique constraint "addresses_pkey"
DETAIL: Key (id)=(1) already exists.
另外，如果我拿出primary_key領域，似乎工作，但它試圖將它們均設置爲相同的地址，我也得到了同樣的錯誤，除了與下一個ID（22，23 ，每次我嘗試24次等）
也許這可以解釋一些問題？我會繼續刺激。
非常感謝你， - 肯
你不能在你的提交歷史看看，看看你修改了什麼？ – 2012-08-07 17:05:45
我不確定導軌如何使用NameCasing破壞名稱，但不應該* belongs_to：human_volunteer * be * belongs_to：humanvolunteer *？ – 2012-08-07 17:09:14
嘿謝謝你的回覆，我試過使用：humanvolunteer，而不是運氣。我還沒有開始使用版本控制（只是在工作的早期階段），所以我沒有任何方式回滾。 – 2012-08-07 17:54:34
