編輯：這是使用Rails 2.3.5獲得一個「有沒有指定的列」當裝載Rails的燈具
出於某種原因，當我嘗試與樂隊信用卡式在我的項目聯繫起來，我得到以下錯誤
SQLite3::SQLException: table credit_cards has no column named band: INSERT INTO "credit_cards" ("created_at", "vault_token", "billing_zipcode", "billing_first_name", "updated_at", "band", "billing_state", "billing_city", "id", "billing_email_address", "billing_country", "billing_address", "billing_phone_number", "billing_last_name") VALUES ('2010-10-08 03:26:07', 'vaulttokenvalue', 12345, 'Test', '2010-10-08 03:26:07', 'beekin', 'TX', 'AnyCity', 714867248, '[email protected]', 'US', '1234 Any Street', '5555555555', 'User')
和
SQLite3::SQLException: table bands has no column named credit_card: INSERT INTO "bands" ("name", "created_at", "next_payment_date", "updated_at", "credit_card", "account_type_id", "id", "hometown_city", "account_status", "subdomain", "hometown_state", "website", "account_type_name") VALUES ('Beekin', '2010-10-08 03:29:16', '2010-10-07', '2010-10-08 03:29:16', 'card_one', 715507355, 862144657, 'Nashville', 'ACTIVE', 'beekin', 'TN', 'http://www.beekin.com', 'MONTHLY')
我的遷移看起來像
class CreateCreditCards < ActiveRecord::Migration
def self.up
create_table :credit_cards do |t|
t.references :band
t.string :billing_first_name
t.string :billing_last_name
t.string :billing_address
t.string :billing_city
t.string :billing_state
t.string :billing_zipcode
t.string :billing_country
t.string :billing_email_address
t.string :billing_phone_number
t.string :vault_token
t.timestamps
end
add_column :bands, :credit_card_id, :integer
end
end
我bands.yml夾具的樣子：
beekin:
name: Beekin
website: "http://www.beekin.com"
hometown_city: Nashville
hometown_state: TN
subdomain: beekin
account_type: monthly
account_type_name: "MONTHLY"
account_status: "ACTIVE"
credit_card: card_one
next_payment_date: <%= Date.today %>
而且我credit_cards.yml夾具的樣子：
card_one:
band: beekin
billing_first_name: Test
billing_last_name: User
billing_address: "1234 Any Street"
billing_city: AnyCity
billing_state: TX
billing_zipcode: 12345
billing_country: US
billing_email_address: "[email protected]"
billing_phone_number: "5555555555"
vault_token: vaulttokenvalue
能有人請指出我在做什麼錯。我已經將它與其他燈具進行了比較，它看起來應該可以工作，但事實並非如此。
has_ has_one：credit_card（帶內模型）和belongs_to：band（在credit_card模型中）。我現在真的很失落。
我敢肯定，你不要以爲一個id分配給固定，因爲你不知道插入數據庫時，某個夾具的ID會是什麼。 – Koby 2010-10-08 11:27:31
我還應該補充說，account_type每月指的是每月的account_types夾具：這就是困擾我的東西。我有他們幾乎完全相同的方式設置和account_type夾具按預期工作，而credit_card不是。 – Koby 2010-10-08 12:38:54
我繼續前進，嘗試了這一點，它的工作，但我的印象是，你沒有想到硬件編碼固定裝置的ID值，做了這種改變，或者這只是一個例外，而不是規則？ – Koby 2010-10-10 01:19:26
