使用 Twitter/Facebook 身份验证的 Rails 4 错误。设计答案

【问题标题】：Rails 4 error with twitter/Facebook authentication. Devise使用 Twitter/Facebook 身份验证的 Rails 4 错误。设计
【发布时间】：2013-06-14 00:45:11
【问题描述】：

我正在与 devise 合作，我正在尝试允许用户使用 twitter/facebook 进行注册。我很困惑，因为我不断得到\ 没有路由匹配 {:controller=>"authentications", :action=>"passthru", :provider=>:twitter, :format=>nil} 缺少必需的键：[:provider]

Routes.rb

 devise_for :users,controllers: {omniauth_callbacks: "authentications", registrations: "registrations"}

AuthenticationController.rb

class AuthenticationsController < ApplicationController
  def index
    @authentications = Authentication.all
  end

  def create
    @authentication = Authentication.new(params[:authentication])
    if @authentication.save
      redirect_to authentications_url, :notice => "Successfully created authentication."
    else
      render :action => 'new'
    end
  end

  def destroy
    @authentication = Authentication.find(params[:id])
    @authentication.destroy
    redirect_to authentications_url, :notice => "Successfully destroyed authentication."
  end
  def twitter
raise omni = request.env["omniauth.auth"].to_yaml
end
end

好的，首先要阅读这个github.com/plataformatec/devise/wiki/OmniAuth:-Overview 非常详细的指南。如有任何进一步的问题，请提出，好像你走错了路

【解决方案1】：

我假设您在 User 模型中有类似下面的内容；因此，您会收到此路由错误。

devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable,
         :validatable, :omniauthable,
         :omniauth_providers => [:facebook],
         :omniauth_providers => [:twitter]

将其更改为以下内容：

devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable,
         :validatable, :omniauthable,
         :omniauth_providers => [:facebook, :twitter]

【解决方案2】：

我关注了omniauth example on github，我有

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  devise :omniauthable, :omniauth_providers => [:google]
end

但只需要一个设计线如下：

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable,
         :omniauthable, :omniauth_providers => [:google]
end
