Question

我正在使用omniauth-twitter gem进行身份验证。我的rails应用程序由Mongodb支持。

点击登录后，它会打开Twitter个人资料。我输入了凭据并被重定向回应用程序，并显示错误

unknown operator: $oid (2)

    def current_user
      @current_user ||= User.find_by(id: session[:user_id])
    end

    helper_method :current_user

它指向@current_user行的错误。但是当我检查数据库中通过执行User.last创建的用户时，我可以看到一个用户对象。

User.rb 文件

class User
  include Mongoid::Document

  field :provider, type: String
  field :uid, type: String
  field :name, type: String
  field :location, type: String
  field :image_url, type: String
  field :url, type: String
  index({ provider: 1, uid: 1 }, { unique: true})

  class << self
      def from_omniauth(auth_hash)
        user = find_or_create_by(uid: auth_hash['uid'], provider: auth_hash['provider'])
        user.name = auth_hash['info']['name']
        user.location = auth_hash['info']['location']
        user.image_url = auth_hash['info']['image']
        user.url = auth_hash['info']['urls']['Twitter']
        user.save!
        user
      end
  end
end

然后我创建了一个会话控制器，如下所示。

class SessionsController < ApplicationController

  def create
    begin
    @user = User.from_omniauth(request.env['omniauth.auth'])
    session[:user_id] = @user.id
    flash[:success] = "Welcome, #{@user.name}!"
      rescue
        flash[:warning] = "There was an error while trying to authenticate you..."
    end
    redirect_to root_path
  end

  def destroy
    if current_user
     session.delete(:user_id)
     flash[:success] = 'See you!'
    end
   redirect_to root_path
  end
end

有人可以帮我解决这个问题吗？

current_user helper方法在mongoid支持的身份验证中返回错误
