问题是,前线发送者没有发出电子邮件,因此,我申请的模型用户证实存在电子邮件,我在回击中发现以下错误:

Email can t be blank

我可在user.rb上查阅。模式:

#config omniauth twitter
def self.find_for_twitter_oauth(access_token, signed_in_resource = nil)
    data = access_token.extra.raw_info
    if user = User.where(:username => data.screen_name).first
        user
    else
        User.create!(:username => data.screen_name, :password => Devise.friendly_token)
    end
end

我在omniauth_questbacks_ Controller.rb上也这样做。

  def twitter
    @user = User.find_for_twitter_oauth(request.env["omniauth.auth"], current_user)
    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Twitter"
      sign_in_and_redirect @user, :event => :authentication
    else
      # http://stackoverflow.com/questions/7117200/devise-for-twitter-cookie-overflow-error
      session["devise.twitter_data"] = request.env["omniauth.auth"].except( extra )
      redirect_to new_user_registration_url
    end
   end

我想迫使用户提供电子邮件地址,以便发送通讯、信使......

www.un.org/spanish/ecosoc 我如何解决这一问题?

谢谢!

Answer 1

增编用户模式:

def email_required?
  super && provider.blank?
end

2. 您可使用对应的密码方法:

def password_required?
  super && provider.blank?
end

在使用总括供应商时,这应优先于外地要求。

Answer 2

我也面临同样的问题,即Twitter没有给你电子邮件,你不得不以另一种方式想取电子邮件。我所列举的唯一解决办法是,压倒电击,利用散射数据自动填写表格,让用户有机会亲自填写邮件,然后在数据库上签字并拯救用户。

探讨以下问题:

在通过OAuth核实其“Twitter”身份后,是否有办法获得用户电子邮件ID?。

A solution is explained thoroughly here: http://asciicasts.com/episodes/236-omniauth-part-2

And on GitHub: https://github.com/fertapric/rails3-mongoid-devise-omniauth/wiki/How-To:-Retrieve-email-information-(middle-step)-from-providers-like-Twitter-or-LinkedIn

出于某种原因,这一问题在谷歌的排名中高于这些联系,因此,我认为,我补充了这些联系。

Answer 4

You need to remove the presence validation of the email field. Follow this post and see if that works. Sorry for the late response, hope this helps.
