Rails 4 - 设计Omniauth（多种策略）

Question

我正在尝试在Rails 4中创建一个应用程序。我已经尝试了最近3年（除了10天），以便设计工作。

我正在尝试按照本教程：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文档中充满了我不理解的错误和组件。

我目前的问题是，当我到达本教程中的完成注册步骤时，表单会要求我提供我的电子邮件地址。

用户控制器的完成注册方法为：

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

当我尝试这个时，我收到了这个错误：

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

此行的错误点：

        <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电子邮件发件人的所有配置详细信息。

当我在生产模式中尝试相同的步骤时，我收到此错误：

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

它正在寻找个人资料ID，因为我在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。

我很想找到成功实施本教程的人，或者可以看看如何使其发挥作用。

我的代码是：

的Gemfile

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

设计邮件 - 确认

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

当前问题摘要：

1. 在开发模式下：确认令牌的链接存在问题。我找不到任何表明可能出现这种情况的材料。错误是：（ActionView :: Template :: Error（{：host =＆gt;“localhost”，：port =＆gt; 3000}的未定义方法`匹配'：哈希）：

2. 在生产模式下，用户在查找配置文件ID时出错。错误消息是：ActionView :: Template :: Error（没有路由匹配{：action =＆gt;“show”，：controller =＆gt;“profiles”，：id =＆gt; 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

1. 身份模型中的所有字段都没有填充。它们都显示为零。

所做的事情与教程中所显示的不同：

1. 我也允许电子邮件注册

2. 我在用户控制器中的操作之前将'finish_sign_up'添加到set_user

3. 我添加了g +策略（这意味着我的宝石略有不同）

4. 我的新用户方法不使用原始信息。它使用oauth处理的信息。

5. 我在完成注册方法中的重定向略有不同，虽然我已经评论过并回到教程中设置的方式以尝试使其工作（尽管上述问题是重复）。

我疯狂地试图解决这些问题。我会说3年太长时间不能坚持这个问题。如果有人可以提供帮助，我会向前支付10倍，然后支付一些。谢谢。

Answer 1

resource

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

我认为这将在生产中完全解决您的问题。由于resource与confirmation_url(nil, confirmation_token: @token)不同，因此尚未设置，并且您基本上正在调用nil，而config.action_mailer.default_url_options正在通过通过错误信息。

在开发过程中，似乎还有一个问题，很可能与您在config/environments/development.rb中配置config.action_mailer.default_url_options[:host] = { host: 'localhost', port: 9000 } 的方式有关，而且最有可能在{{3}中引发异常}}。我怀疑你有类似的东西：

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

将其更改为：

config.action_mailer.default_url_options

看看是否能解决所有问题。如果我对config/environments/development.rb的配置方式有误，请粘贴您的{{1}}以及开发错误中的完整堆栈跟踪，以便我们为您提供进一步的帮助。
