我在用着：
我最近设置了我的omniauth-facebook一切正常。现在我想添加omniauth-twitter但不知怎的，我把事情搞砸了，非常糟糕。
1.)设置我的Omniauth-Facebook我这样做了（简而言之）：
gem 'omniauth'
gem 'omniauth-facebook'
2.)添加了列“provider" and "uid“到我的用户模型。
3.)接下来，我在 config/initializers/devise.rb 中声明了提供程序：
require "omniauth-facebook"
config.omniauth :facebook, "App_ID", "App_Secret",
{:scope => 'email,offline_access',
:client_options => {:ssl => {:ca_file => 'lib/assets/cacert.pem'}},
:strategy_class => OmniAuth::Strategies::Facebook}
4.)我编辑了我的模型 User.rb
# Facebook Settings
def self.find_for_facebook_oauth(auth, signed_in_resource = nil)
user = User.where(provider: auth.provider, uid: auth.uid).first
if user.present?
user
else
user = User.create(first_name:auth.extra.raw_info.first_name,
last_name:auth.extra.raw_info.last_name,
facebook_link:auth.extra.raw_info.link,
user_name:auth.extra.raw_info.name,
provider:auth.provider,
uid:auth.uid,
email:auth.info.email,
password:Devise.friendly_token[0,20])
end
end
并添加了要设计的属性：
:omniauth_providers => [:facebook]
5.)我编辑了路线：
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
THE END
虽然这对于 Facebook 来说非常有效，但我已经尝试了几个小时才能让它在 Twitter 上工作，但我就是不明白。
如果有这方面经验的人或者只是知道解决方案的人可以帮助我进行设置，我将非常感激:)
谢谢你们，对这么长的帖子表示歉意。
此外
Twitter 不提供 :email 属性，所以我猜我必须拆分我的用户注册过程？
My Twitter行动在我的用户模型
# Twitter Settings
def self.find_for_twitter_oauth(auth, signed_in_resource=nil)
user = User.where(:provider => auth[:provider], :uid => auth[:uid]).first
unless user
user = User.create(:first_name => auth[:name],
:user_name => auth[:screen_name],
:provider => auth[:provider], :uid => auth[:uid],
:password => Devise.friendly_token[0,20]
)
end
user
end
# build auth cookie hash for twitter
def self.build_twitter_auth_cookie_hash data
{
:provider => data.provider, :uid => data.uid.to_i,
:access_token => data.credentials.token, :access_secret => data.credentials.secret,
:first_name => data.name, :user_name => data.screen_name,
}
end
我必须迁移一个可确认的用户->如何：向用户添加 :confirmable
我公司的问题，（至少我现在已经到了这一点:)）
要解决电子邮件问题，您可以设置一个虚拟邮件，或者添加第二步，让用户添加他/她的电子邮件。
虚拟邮件：
class User < ActiveRecord::Base
before_create :set_dummy_mail, if self.provider == "twitter"
private
def set_dummy_mail
self.email = "#{self.name}[email protected]"
end
end
或者第二步选项：
如果提供商是 twitter 并且电子邮件为空，请修改您的控制器以重定向到添加电子邮件步骤。如果提供商是 Twitter，也许您还必须修改验证以允许创建时电子邮件为空白。
UPDATE: 我是这样做的：
Gemfile:
gem "devise"
gem "omniauth"
gem "omniauth-facebook"
gem "omniauth-twitter"

如果您使用不同的版本，您可能必须更改一些东西..

也许您必须修改我的解决方案的一个或其他部分..您还可以重构用户模型中的两种方法（find_for_facebook_auth、find_for_twitter_auth）以使用一种动态方法。尝试一下，如果仍有问题请告诉我。如果您发现任何拼写错误，也请告诉我。您还应该编写测试来检查系统内的所有内容。
