Rails 4 - 設計Omniauth（多策略）

Question

我想在Rails 4中創建一個應用程序。我一直在嘗試過去3年（除了10天），以獲得設計工作。

我想按照這個教程：http://sourcey.com/rails-4-omniauth-using-devise-with-twitter-facebook-and-linkedin/

請不要推薦其他教程/寶石文檔。我已經嘗試了至少30個其他教程，並且該寶石文檔充滿了我不明白的錯誤和組件。

我目前的問題是，當我到達本教程的完成註冊步驟時，表單會詢問我的電子郵件地址。

的用戶控制器具有完成註冊方法：在這一行

undefined method `match' for {:host=>"localhost", :port=>3000}:Hash 

錯誤點：

 <div class="intpol3"><%= link_to 'Confirm my account', confirmation_url(@resource, confirmation_token: @token) %></div> 

def finish_signup 
    # authorize! :update, @user 
    if request.patch? && params[:user] #&& params[:user][:email] 
     if @user.update(user_params) 
     @user.skip_reconfirmation! 
     # sign_in(@user, :bypass => true) 
     # redirect_to root_path, notice: 'Your profile was successfully updated.' 
     # redirect_to [@user, @user.profile || @user.build_profile] 
     sign_in_and_redirect(@user, :bypass => true) 
     else 
     @show_errors = true 
     end 
    end 
    end 

當我嘗試這一點，我得到這個錯誤

我的開發環境設置爲包含我的電子郵件發件人的所有配置詳細信息。

當我嘗試在生產模式相同的步驟，我得到這個錯誤：

after_create :gen_profile 

    def gen_profile 
    Profile.create(user: self) # Associations must be defined correctly for this syntax, avoids using ID's directly. 
    # Profile.save 
    end 

：

ActionView::Template::Error (No route matches {:action=>"show", :controller=>"profiles", :id=>nil} missing required keys: [:id]): 

它尋找一個配置文件ID，因爲我在我的用戶模型有一個after_create行動

本教程中的其他問題是身份表中的字段未被填充。

我很想找到已成功實施本教程的人員或者可以看到如何完成此項工作。

我的代碼是：

的Gemfile

gem 'devise', '3.4.1' 
gem 'devise_zxcvbn' 
gem 'omniauth' 
gem 'omniauth-oauth2', '1.3.1' 
gem 'omniauth-google-oauth2'

色器件郵包 - 電流問題的確認

 <div class="intpol3"><%= link_to 'Confirm my account', confirmation_url(@resource, confirmation_token: @token) %></div> 

內容：

1. 在開發模式：有一個與一個問題鏈接到confi信息令牌。我找不到任何可能會出現這種情況的材料。該錯誤是：（::的ActionView模板::錯誤（未定義的方法`匹配」爲{：主機=> 「本地主機」，：端口=> 3000}：散列）：

2. 在生產模式中，存在一個錯誤消息是：ActionView :: Template :: Error（沒有路由匹配{：action =>「show」，：controller =>「profiles」，：id => nil}缺少必需的密鑰：[：ID]）：

我的簡檔航線：

resources :profiles, only: [:show, :edit, :update, :destroy] 
resources :users do 
    resources :profiles, only: [:new, :create] 
    end 

無在字段身份模型正在填充。他們都顯示爲零。

不同的事情做得比如圖教程：

1. 我也讓電子郵件註冊

2. 我的用戶控制器動作之前加上「finish_sign_up」到set_user

3. 我加了g +策略（這意味着我的寶石略有不同）

4. 我的新用戶方法不使用原始信息。它使用oauth處理的信息。

5. 我在完成註冊方法中的重定向略有不同，儘管我已經評論過並回到了教程中設置的方式以嘗試使其工作（儘管上述問題正在重複）。

我要瘋了試圖解決這些問題。我會說3年太長了，不能堅持這個問題。如果任何人都可以提供幫助，我會先付10倍，然後再付一些。謝謝。

Answer 1

<div class="intpol3"><%= link_to 'Confirm my account', 
    confirmation_url(@resource, confirmation_token: @token) %></div> 

嘗試resource而不是@resource。 AFAIK它只是一個helper_method，而不是一個實例變量。

我認爲這將在生產中完全解決您的問題。由於@resource與resource不同，它尚未設置，並且您基本上呼叫confirmation_url(nil, confirmation_token: @token)，並且nil正在傳遞給錯誤消息。

在開發過程中，似乎還有一個額外的問題，最有可能與您如何在config/environments/development.rb中配置config.action_mailer.default_url_options以及最有可能在ActionDispatch::Http::Url.build_host_url中引發異常有關。我懷疑你有這樣的：

config.action_mailer.default_url_options[:host] = { host: 'localhost', port: 9000 } 

修改成：

config.action_mailer.default_url_options[:host] = 'localhost:9000' 

，看看是否能解決一切問題。如果我對如何配置config.action_mailer.default_url_options錯誤，請粘貼您的config/environments/development.rb和您的開發錯誤的完整堆棧跟蹤，以便我們可以進一步幫助您。
