将Twitter帐户连接到现有的设备帐户

用户可以通过Devise注册。

注册后，用户应该可以连接他的

• Twitter Account

在过去，我使用omniauth让facebook和twitter连接工作。 但在这种特殊情况下，我需要将Twitter帐户链接到现有的设备帐户。

任何人都可以帮助我从哪里开始或阅读，我完全无能为力。

gem

 gem 'omniauth-twitter' gem 'omniauth-facebook' gem 'omniauth-linkedin' 

在视图中

 <%= check_connection('Facebook')%> <%= check_connection('Linkedin')%> <%= check_connection('Twitter')%> 

助手

  def check_connection(provider) if current_user.has_connection_with(provider) html = link_to disconnect_path(social: provider.downcase), class: "#{provider}-m phone-verified row" do content_tag :span, 'Verified', class: "verified" end else html = link_to user_omniauth_authorize_path(provider: provider.downcase), class: "#{provider}-m phone-verified row" do content_tag :span, 'Click to verify', class: "un-verified" end end end 

在用户模型中 – 对你而言，这可能会有所不同

  devise :database_authenticatable, :registerable, :confirmable, :lockable, :recoverable, :rememberable, :trackable, :validatable, :omniauthable, :omniauth_providers => [:facebook, :twitter, :linkedin] has_many :authorizations, :dependent => :destroy def has_connection_with(provider) auth = self.authorizations.where(provider: provider).first if auth.present? auth.token.present? else false end end 

在我的路线

  devise_for :users, :controllers => {:registrations => "users/registrations", :sessions => "users/sessions", :passwords => "users/passwords", :omniauth_callbacks => "users/omniauth_callbacks" #<- this one you need } 

创建授权表 - 请参阅此链接uninitialized constant User :: Authorization | omn​​iauth

 class CreateAuthorizations < ActiveRecord::Migration def change create_table :authorizations do |t| t.string :provider t.string :uid t.integer :user_id t.string :token t.string :secret t.string :first_name t.string :last_name t.string :name t.string :link t.timestamps end end end 

OmniauthCallbacksController / controllers / users / ...
