創建nested_attributes使得before_create不行

我試圖創建在控制檯的用戶這樣做：創建nested_attributes使得before_create不行

2.2.1 :012 > u.save! 
    (0.2ms) BEGIN 
    User Exists (0.7ms) SELECT 1 AS one FROM "users" WHERE LOWER("users"."email") = LOWER('[email protected]') LIMIT 1 
    SQL (2.1ms) INSERT INTO "users" ("id", "first_name", "last_name", "email", "title", "time_zone", "company_id", "password_digest", "created_at", "updated_at", "activation_digest") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11) RETURNING "id" [["id", 200], ["first_name", "Random"], ["last_name", "Dude"], ["email", "[email protected]"], ["title", "CEO"], ["time_zone", "Stockholm"], ["company_id", 1], ["password_digest", "$2a$10$bHHA/JP5IMrucGUXRWMpsO8sInaouSqn48M.fDHpjGdvedu3Napra"], ["created_at", "2015-10-11 23:09:38.213109"], ["updated_at", "2015-10-11 23:09:38.213109"], ["activation_digest", "$2a$10$WF3bUOtbC1gk4ZnX58cJZO5k7P7YV6wvhmwz7EErTdvIseNuy0oyq"]] 
2.2.1 :013 > u.activation_token 
=> "vKrs0jtvZRiyU-YVE-aPXw"

現在，當我嘗試創建before_create不起作用用戶，我試圖改變它以before_validation，並沒有工作。

該用戶是來自公司的嵌套屬性，並且在公司＃new中創建。

class User < ActiveRecord::Base 
    belongs_to :company 
    attr_accessor :remember_token, :activation_token, :reset_token 
    before_save :downcase_email 
    before_create :create_activation_digest

現在，當我做@ user.activation_token它返回nil。下面是當我嘗試它的應用程序控制臺日志：

ActionController::UrlGenerationError - No route matches {:action=>"edit", :controller=>"account_activations", :email=>"[email protected]", :id=>nil} missing required keys: [:id]:

現在我看到返回activation_digest，所以我覺得這個問題是文采只是before_create不工作？這是奇怪，因爲那不應該是能夠創建激活消化爲兩個連接：

# Creates and assigns the activation token and digest. 
def create_activation_digest 
    self.activation_token = User.new_token 
    self.activation_digest = User.digest(activation_token) 
end

你可以發佈'account_activations_controller.rb'文件嗎？也是相應的視圖文件。 –

另外，請發佈您的'routes.rb'文件。 –

你的錯誤說：

ActionController::UrlGenerationError - No route matches {:action=>"edit", :controller=>"account_activations", :email=>"[email protected]", :id=>nil} missing required keys: [:id]:

好像在您看來，您所呼叫edit_account_activation_path沒有id參數，這就是爲你創建問題。嘗試發送user.id作爲edit_account_activation_path調用中的參數。

事情是這樣的：

edit_account_activation_path(user.email, user.id)

這應該解決您的問題。
