Question

我尝试使用google帐户管理用户注册我的rails 4.0.0应用。设计完美。现有用户可以使用Google帐户登录。但是我使用Google Oauth 2进行新用户注册时遇到了一些困难。例如：我有谷歌帐户“example@google.com”。它已登录到我当前的PC上。当我尝试使用此帐户注册我的应用程序时，它会生成空白注册表单。如果我不手动提供电子邮件，登录，全名等 - 我有错误消息，他们“不能空白”。我猜解决方案是为文本字段创建默认值以获取用户详细信息。所以，我的问题是如何为视图中的变量提供等于谷歌帐户变量的值？

新用户注册中form_for中的电子邮件字段：

= f.email_field :email, :autofocus => true, :value => 'how can i put auth.info.email here?'

omniauth_callbacks_controller.rb：

class OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def google_oauth2
    user = User.from_omniauth(request.env["omniauth.auth"])
    if user.persisted?
      flash.notice = "Signed in Through Google!"
      sign_in_and_redirect user
    else
      session["devise.user_attributes"] = user.attributes
      flash.notice = "You are almost Done! Please provide a password to finish setting up your account"
      redirect_to new_user_registration_url
    end
  end
end

来自用户模型的 omniauth方法：

  def self.from_omniauth(auth)
    if user = User.find_by_email(auth.info.email)
      user.provider = auth.provider
      user.uid = auth.uid
      user
    else
      where(auth.slice(:provider, :uid)).first_or_create do |user|
        user.provider = auth.provider
        user.uid = auth.uid
        user.full_name = auth.info.name
        user.email = auth.info.email # THIS (user.email) value i want to provide to my registration form as default value
        user.birthday = auth.info.birthday
        user.avatar = auth.info.image
     end
    end
  end

我遇到了与GitHub相同的问题，你可以看看我的用户模型

使用Devise和omniauth-google-oauth2注册新用户
