如何绕过Twitter全身份验证"email can't be blank"错误？

Question

我在使用Twitter身份验证时遇到了一点麻烦。我一直收到邮件不能为空，重定向到注册，但在插入邮件并点击注册后，我仍然得到相同的错误。我试图使它不需要，但我得到的错误说，有人与"电子邮件已经存在。谢谢。

设计Routes.rb

    def has_role?(role)
        return true;
      end 
    def self.from_omniauth(auth)
      where(auth.slice(:provider, :uid)).first_or_create do |user|
        user.provider = auth.provider
        user.uid = auth.uid
        user.username = auth.info.nickname
      end
    end
def self.new_with_session(params, session)
  if session["devise.user_attributes"]
    new(session["devise.user_attributes"]) do |user|
      user.attributes = params
      user.valid?
    end
  else
    super
  end
end
def password_required?
  super && provider.blank?
end
def update_with_password(params, *options)
  if encrypted_password.blank?
    update_attributes(params, *options)
  else
    super
  end
end
end
              Call Back Controller 
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def all
    user = User.from_omniauth(request.env["omniauth.auth"])
    if user.persisted?
      flash.notice = "Signed in!"
      sign_in_and_redirect user
    else
      session["devise.user_attributes"] = user.attributes
      redirect_to new_user_registration_url
    end
  end
  alias_method :twitter, :all
end

Answer 1

您可以将username定义为您的"认证密钥"，而不是email by取消注释

配置。Authentication_keys = [:email]

配置/初始化/devise.rb

并将其改为

配置。Authentication_keys = [:username]

Answer 2

我也有同样的问题。此错误是由于在设计用户模型电子邮件字段设置为NotNull。解决方案:-

1。设置email字段允许空值

2。我把twitter的邮件保存在了我的电子邮件栏中这是twitter的代码

def self.find_for_twitter_oauth(auth, signed_in_resource=nil)
  user = User.where(:provider => auth.provider, :uid => auth.uid).first
  unless user
    temp = Tempfile.new([auth["uid"], ".jpg"])
    temp.binmode
    temp.write(open(auth["info"]["image"]).read)
    user = User.create(name:auth.extra.raw_info.name,
                         provider:auth.provider,
                         uid:auth.uid,
                         email:auth.info.email,
                         password:Devise.friendly_token[0,20],
                         image:temp                          
                         )
        user.build_profile(name:user.name,image:temp)
    user.profile.save     
  end
  user
end
