Question

尝试按照https://github.com/plataformatec/devise/#configuring-controllers自定义登录行为。

使用Rails 5.2.2，ruby 2.5.3，设计4.6.1。

我用过user_signed_in吗？在application_controller.rb中使用before_action进行选择查询并生成current_user对象。

这是否意味着用户已登录？这是预期的行为吗？

如果是的话，如何在application_controller中检查用户登录，我需要根据用户详细信息设置应用程序级别的值。

如果我做错了，请帮助我并纠正我。

未对默认的 devise.rb

进行任何更改

routes.rb

Rails.application.routes.draw do
  resources :profiles
  devise_for :users, controllers: { sessions: 'users/sessions' }
  root to: "profiles#index"
end

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery prepend: true
  before_action :simple_call, if: proc { user_signed_in? }
  ## USER BELOW LINE AS WELL BY COMMENTING ABOVE RESULTS SAME
  #before_action :simple_call, if: proc { current_user.present? }
  def  simple_call
    p '--------CURRENT_USER----'
    p current_user
  end
end

users / sessions_controller.rb

# frozen_string_literal: true

class Users::SessionsController < Devise::SessionsController
  # before_action :configure_sign_in_params, only: [:create]

  # GET /resource/sign_in
  # def new
  #   super
  # end

  # POST /resource/sign_in
  def create
    p 'this line is printing after before action'
    super do |resource|
     p 'this is inside create'
    end
  end

  # DELETE /resource/sign_out
  # def destroy
  #   super
  # end

  # protected

  # If you have extra params to permit, append them to the sanitizer.
  # def configure_sign_in_params
  #   devise_parameter_sanitizer.permit(:sign_in, keys: [:attribute])
  # end
end

在登录期间

登录

更新

请参阅此讨论。 https://github.com/plataformatec/devise/issues/4951

我相信在即将发布的版本中将解决此问题。

Answer 1

您很有可能需要先致电before_filter :authenticate_user!，然后user_signed_in?支票才能正常运行。

在使用user_signed_in进行操作之前？签入应用程序控制器进行数据库调用并返回用户
