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，因为我不断得到\ 没有路由匹配{：controller =＆gt;“authentications”，：action =＆gt;“passthru”，：provider =＆gt;：twitter，：format =＆gt; 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]

Answer 2

我关注的是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

但需要只有一个设计线如下：

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

使用Twitter / Facebook身份验证时出现Rails 4错误。设计
