ruby-on-rails - Rails 4 - Devise Omniauth(多种策略)

Question

我正在尝试在 Rails 4 中制作一个应用程序。过去 3 年(除了 10 天)我一直在尝试让设计工作。

我正在尝试遵循本教程:http://sourcey.com/rails-4-omniauth-using-devise-with-twitter-facebook-and-linkedin/

请不要推荐其他教程/gem 文档。我已经尝试了至少 30 个其他教程，并且 gem 文档充满了我不理解的错误和组件。

我当前的问题是，当我完成本教程中的注册步骤时，表单会要求我提供电子邮件地址。

用户 Controller 有一个完成注册方法:

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

当我尝试此操作时，出现此错误:

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

该行的错误点:

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

我的开发环境设置为包含我的电子邮件发件人的所有配置详细信息。

当我在生产模式下尝试相同的步骤时，出现此错误:

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

它正在寻找配置文件 ID，因为我的用户模型中有一个 after_create 操作:

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

本教程的另一个问题是身份表中的字段未填充。

我很想找到已成功实现本教程或可以了解如何实现此功能的人。

我的代码是:

gem 'devise_zxcvbn'

设计邮件程序 - 确认

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

当前问题总结:

1. 在开发模式下:确认 token 的链接存在问题。我找不到任何 Material 表明为什么会出现这种情况。错误是:(ActionView::Template::Error (未定义方法 `match' for {:host=>"localhost", :port=>3000}:Hash):

2. 在生产模式下，用户查找个人资料 ID 时出错。错误消息为: ActionView::Template::Error (没有路由匹配 {:action=>"show", :controller=>"profiles", :id=>nil} 缺少必需的键: [:id]):

我的个人资料路线是:

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

身份模型中的任何字段均未填充。它们都显示为零。

所做的事情与教程中所示的不同:

1. 我还允许电子邮件注册

2. 我在用户 Controller 中的操作之前将“finish_sign_up”添加到 set_user

3. 我添加了 g+ 策略(这意味着我的 gem 略有不同)

4. 我的新用户方法不使用原始信息。它使用 oauth 处理过的信息。

5. 我在完成注册方法中的重定向略有不同，尽管我已经对此进行了评论并返回到教程中规定的方式以尝试使其正常工作(尽管上述问题是重复)。

我正在疯狂地尝试解决这些问题。我想说三年对于这个问题来说太长了。如果有人能提供帮助，我会支付 10 倍，然后再支付一些。谢谢。

Answer 1

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

尝试resource而不是@resource。 AFAIK 它只是一个 helper_method，而不是一个实例变量。

我认为这将完全解决您在生产中的问题。由于 @resource 与 resource 不同，因此尚未设置，您基本上是在调用 confirmation_url(nil,confirmation_token: @token)，并且 nil 被传递到错误消息。

在开发过程中，似乎存在一个额外的问题，这很可能与您在 config/environments/development.rb< 中配置 config.action_mailer.default_url_options 的方式有关 最有可能的是在 ActionDispatch::Http::Url.build_host_url 中引发异常。我怀疑你有类似的东西:

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

将其更改为:

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

看看这是否能解决所有问题。如果我对 config.action_mailer.default_url_options 的配置方式有误，请粘贴您的 config/environments/development.rb 以及开发错误中的完整堆栈跟踪，以便我们可以进一步帮助您。
