Hartl的Rails教程 - false和「authenticated？」 （activation_token）

Question

尊敬的同事們。

我在做Hartl的Railstutorial並遇到問題，我解決不了。根據教程我做的每一步。問題的

說明：

如果做運動，「？從清單11.26使用了廣義驗證方法，驗證用戶進行身份驗證。根據記住這兩個單詞和激活令牌」。

當正確的結果應該是這樣的：

>> User.authenticated (: remember, user.remember_token) 
=> True 
>> User.authenticated (: activation, user.activation_token) 
=> True 

同時，在我的情況下，它是：

user = User.create(name: "Test User", email: "test@example.com", password: "foobar", password_confirmation: "foobar") 
    (0.1ms) begin transaction 
    User Exists (0.2ms) SELECT 1 AS one FROM "users" WHERE LOWER("users"."email") = LOWER(?) LIMIT ? [["email", "test@example.com"], ["LIMIT", 1]] 
    SQL (0.3ms) INSERT INTO "users" ("name", "email", "created_at", "updated_at", "password_digest", "activation_digest") VALUES (?, ?, ?, ?, ?, ?) [["name", "Test User"], ["email", "test@example.com"], ["created_at", 2017-02-26 20:36:50 UTC], ["updated_at", 2017-02-26 20:36:50 UTC], ["password_digest", "$2a$10$caQcP8VAQJaUwaFQwOt4j.RadReeSllF5TBEwbvuu1D08.A/LPOlC"], ["activation_digest", "$2a$10$q2aPIqOaNWlZstIsKnCjbev7DqC2UXkRoNTMO3XAvYj3tIcVG40Gy"]] 
    (41.1ms) commit transaction 
=> #<User id: 104, name: "Test User", email: "test@example.com", created_at: "2017-02-26 20:36:50", updated_at: "2017-02-26 20:36:50", password_digest: "$2a$10$caQcP8VAQJaUwaFQwOt4j.RadReeSllF5TBEwbvuu1D...", remember_digest: nil, admin: false, activation_digest: "$2a$10$q2aPIqOaNWlZstIsKnCjbev7DqC2UXkRoNTMO3XAvYj...", activated: false, activated_at: nil> 


>> User.authenticated (: activation, user.activation_token) 
=> False 

結果，我不能讓用戶激活在後期階段。

有沒有人能給我理由？

我解決了這個問題。

我在文件中的錯誤user.rb

我：

def create_activation_digest 
    self.activation_token = User.new_token 
    self.activation_digest = User.digest(:activation_token) 
    end 

應該是：（activation_token沒有 「：」）

def create_activation_digest 
    self.activation_token = User.new_token 
    self.activation_digest = User.digest(activation_token) 
    end 

我提出了一個解決方案，因爲它對某人有用。

謝謝你的建議。
