Omniauth-Facebook 的其他用户属性验证失败
Additional User Attribute Validation Failure with Omniauth-Facebook
大家好，在此先感谢您的专业知识和帮助。
我在 Rails 上的 Ruby 方面不是很熟练（仅仅 3 个月前才开始），并且正在构建一个相当复杂的应用程序。我遇到了关于 Omniauth-Facebook 的障碍。我有 Devise、omniauth-facebook、一个 omniauth_callbacks 控制器、一个 Devise registrations_controller、一个 Devise users_controller 和一个对多个字段进行验证的用户模型（请参阅下面的所有代码).在设置这一切时，我或多或少地遵循了这个 Youtube 视频：https://www.youtube.com/watch?v=VeUX3pWn28w 和许多其他分散的指南，当我尝试进行故障排除时。有些已经过时了，我什至不确定我的代码的哪些部分可能已经过时了。
我的注册表单的工作原理：用户可以填写我的自定义注册表单并正确添加到数据库中，所有 Devise 操作都正常运行并且所有自定义 table 属性都被记录下来。用户可以单击 "Signup with Facebook" 按钮并被定向到 Facebook 到 login/signup，其中返回提供者和 UID，以及（看起来）名字、电子邮件和密码。我的架构中默认有 State 和 Zip，因此不会引发验证异常。
似乎失败的地方：当 Facebook 发回信息时，它似乎在电子邮件返回时中断 ("User Exists")。即使我已经包含 "auth.info.last_name, auth.info.image, etc."，终端错误也不会显示从 Facebook 返回的那些额外字段，但验证不会抛出异常，包括电子邮件。在我的数据库中，我确保该电子邮件没有重复。由于我的数据库和验证，我需要的姓氏、性别、出生日期、地址和城市似乎也没有填写，这是可以理解的（last_name 除外），因为我无法从 Facebook 收到这些信息.
这就是我想要的：正如我上面提到的，Facebook 似乎没有返回 "last_name"、"address" 或 "image"。我还需要包括出生日期、性别和他们所在的城市。看来我无法从 omniauth-facebook 做到这一点，因为 Facebook 的 Auth Hash 不包括这些字段。我如何允许用户通过 Facebook 使用这些提供的字段进行注册，通过 Facebook 登录，然后被定向到一个页面，他们可以在其中输入我的数据库所需的缺少的附加信息？因此，在通过 facebook 注册后，如何将用户发送到另一个页面（没有抛出那些验证异常？），然后输入该附加信息（姓氏、出生日期、地址、地址 2 [如果需要]、性别和 city/state/zip、or/else 是否缺少任何其他字段）？为什么 "last_name" 会失败，但 "first_name" 没问题？
下面是你们可能需要的所有东西的图片，我认为可能需要。同样，我了解 Ruby 和 Rails 的基础知识，并认为自己处于中等水平，但需要帮助来理解 why/how 答案解决了我遇到的这个问题。遗憾的是，我对高级路由和控制器的工作原理缺乏了解，所以如果您有任何资源可以帮助我提高对该主题的了解，我也将不胜感激。

我的浏览器和终端错误：
在您的 Devise 初始值设定项 (config/initializers/devise.rb) 中，您需要使用 info_fields 参数来添加您希望 Facebook 加入的项目 return。默认情况下，Facebook 只有 return 的姓名、电子邮件和 ID。例如：
# Add a new OmniAuth provider. Check the wiki for more information on setting
# up on your models and hooks.
config.omniauth :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_APP_SECRET'],
callback_url: 'https://ossemble-workspace-twistedben.c9users.io/users/auth/facebook/callback',
info_fields: 'email,name,birthday,locale,gender'
您可以获得 Facebook 用户对象 here 上可用项目的列表。某些项目（例如生日）需要用户的许可和 Facebook 对您的应用的特别批准。您需要在文档中彻底探索这一点。
此外，Facebook 用户可以拒绝您的应用访问 his/her 个人资料的任何部分。仅仅因为您请求来自 Facebook 的电子邮件，并不保证回电将包括电子邮件。您的应用需要妥善处理这些情况。
在您的情况下，您可能想要创建一个新的用户记录但不立即保存它。相反，将该对象传递给注册表单，让用户填写 his/her 个人资料中的空白。或者您可以在不验证的情况下保存新记录 (user.save(validate:false))。
此外，我建议将您的应用程序 ID 和应用程序密码存储在环境变量 (ENV[...]) 中，而不是将其签入源代码或在线发布。您会想立即获得一个新的 Facebook 秘密。

我的浏览器和终端错误：
在您的 Devise 初始值设定项 (config/initializers/devise.rb) 中，您需要使用 info_fields 参数来添加您希望 Facebook 加入的项目 return。默认情况下，Facebook 只有 return 的姓名、电子邮件和 ID。例如：
# Add a new OmniAuth provider. Check the wiki for more information on setting
# up on your models and hooks.
config.omniauth :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_APP_SECRET'],
callback_url: 'https://ossemble-workspace-twistedben.c9users.io/users/auth/facebook/callback',
info_fields: 'email,name,birthday,locale,gender'
您可以获得 Facebook 用户对象 here 上可用项目的列表。某些项目（例如生日）需要用户的许可和 Facebook 对您的应用的特别批准。您需要在文档中彻底探索这一点。
此外，Facebook 用户可以拒绝您的应用访问 his/her 个人资料的任何部分。仅仅因为您请求来自 Facebook 的电子邮件，并不保证回电将包括电子邮件。您的应用需要妥善处理这些情况。
在您的情况下，您可能想要创建一个新的用户记录但不立即保存它。相反，将该对象传递给注册表单，让用户填写 his/her 个人资料中的空白。或者您可以在不验证的情况下保存新记录 (user.save(validate:false))。
此外，我建议将您的应用程序 ID 和应用程序密码存储在环境变量 (ENV[...]) 中，而不是将其签入源代码或在线发布。您会想立即获得一个新的 Facebook 秘密。
