在devise 2.0上跳过omniauth-twitter的电子邮件验证 [英] Skip email validation for omniauth-twitter on devise 2.0

问题描述

我正在使用devise 2.0和gem omniauth-twitter

问题是，twitter不会发送电子邮件，所以我的应用程序的模型用户验证有一封电子邮件，并在回调中收到以下错误：

 电子邮件不能为空
  

我有这在我的 user.rb 模型中：

  #config omniauth twitter 
 def self。 find_for_twitter_oauth（access_token，signed_in_resource = nil）
 data = access_token.extra.raw_info 
如果user = User.where（：username => data.screen_name）.first 
 user 
 else 
 User.create！（：username => data.screen_name，：password => Devise.friendly_token）
 end 
 end 
  / pre> 
 
 
我有这个在我的 omniauth_callbacks_controller.rb  
  def twitter 
 @user = User.find_for_twitter_oauth（request.env [omniauth.auth]，current_user）
如果@ user.persisted？ 
 flash [：notice] = I18n.tdevise.omniauth_callbacks.success，：kind => Twitter
 sign_in_and_redirect @user，：event => ：身份验证
 else 
＃http://stackoverflow.com/questions/7117200/devise-for-twitter-cookie-overflow-error 
会话[devise.twitter_data] =请求。 env [omniauth.auth]。except（'extra'）
 redirect_to new_user_registration_url 
 end 
 end 
  
我想要强制给用户发送电子邮件地址发送通讯，广告等... 
 
 
 
 我如何解决这个问题？ 
 
 
 
谢谢！
解决方案
将其添加到您的用户模型中：
  def email_required？ 
超级&& provider.blank？ 
 end 
  
您可以使用等效的密码方法：
  def password_required？ 
超级&& provider.blank？ 
 end 
  
使用Omniauth提供程序时，这应该覆盖字段的要求。
 
I'm using devise 2.0 and gem omniauth-twitter

The problem is that twitter does not send an email in response, so the model user of my application validates that there is an email and I get the following error in the callback:
Email can't be blank
I have this in my user.rb model:
#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
and I have this in my omniauth_callbacks_controller.rb
  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
I want force to user to give a email address for send newsletter, advertirser...etc

How can I fix this problem?

Thank you!
解决方案
Add this to your User model:
def email_required?
  super && provider.blank?
end
You can use an equivalent method for the password:
def password_required?
  super && provider.blank?
end
This should override the field requirements when using Omniauth providers.
