使用Twitter/Facebook身份验证时出现Rails 4错误.设计

Question

我正在使用设计,我正在尝试允许用户使用twitter/facebook注册.我很困惑,因为我一直得到\没有路由匹配{:controller =>"authentications",:action =>"passthru",:provider =>:twitter,:format => nil}缺少必需的密钥:[:provider]

的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

Answer 1

我假设你在用户模型中有类似下面的东西; 因此,您收到此路由错误.

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]
