How do you implement your own authentication with ActiveAdmin without Devise? ActionView::Template::Error: undefined method

Question

根据 ActiveAdmin documentation，您只需创建 authenticate_admin_user! 和 current_admin_user 方法即可创建身份验证。我这样做了，提供了正确的密码，但它给了我一个错误页面。还需要什么？

application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  def authenticate_admin_user!
    puts session[:user].inspect
    redirect_to login_path unless session[:user] && session[:user]["admin"] == true
  end

  def current_admin_user
    session[:user]
  end

end

config/initalizers/active_admin.rb

  # == User Authentication
  #
  # Active Admin will automatically call an authentication
  # method in a before filter of all controller actions to
  # ensure that there is a currently logged in admin user.
  #
  # This setting changes the method which Active Admin calls
  # within the application controller.
  config.authentication_method = :authenticate_admin_user!

  # == Current User
  #
  # Active Admin will associate actions with the current
  # user performing them.
  #
  # This setting changes the method which Active Admin calls
  # (within the application controller) to return the currently logged in user.
  config.current_user_method = :current_admin_user

index_controller.rb

class IndexController < ApplicationController
  def login_post
    if Digest::SHA256.base64digest(params[:password]) == "xxxxxxxxxxxxxx="
      session[:user] = {"admin" => true}
      redirect_to admin_root_path
    else
      flash.now.alert = 'Invalid password.'
      render :login
    end

现在报错

ActiveAdmin 加载正常，config.authentication_method 和 config.current_user_method 评论。

Rails 5.0.7，ActiveAdmin 1.3.0

我通过添加

修复了它 routes.rb

get :logout, controller: :index, as: :destroy_admin_user_session

index_controller.rb

  def logout
    reset_session
    redirect_to :root
  end
