Rails_admin 和专家：#<RailsAdmin::MainController 的未定义方法“策略”

Question

我在 rails 5 上，我正在尝试通过专家为我的 rails_admin 面板实施授权。所以我在我的应用程序控制器中包含了 pundit 并安装了 the rails_admin_pundit gem 正如你在我的 Gemfile 的这个片段中看到的那样：

gem 'devise'
gem 'devise-i18n'
gem 'rails_admin', '~> 1.0'
gem 'rails_admin-i18n'
gem 'rails_admin_tag_list', github: 'kryzhovnik/rails_admin_tag_list'
gem 'pundit'
gem "rails_admin_pundit", :github => "sudosu/rails_admin_pundit"

申请政策：

class ApplicationPolicy
  attr_reader :current_user, :record

  def initialize(current_user, record)
    @user = current_user
    @record = record
  end

  def index?
    false
  end

  def show?
    scope.where(:id => record.id).exists?
  end

  def create?
    false
  end

  def new?
    create?
  end

  def update?
    false
  end

  def edit?
    update?
  end

  def destroy?
    false
  end

    def rails_admin?(action)
        case action
        when :dashboard
            @user.admin?
        when :index
            @user.admin?
        when :show
            @user.admin?
        when :new
            @user.admin?
        when :edit
            @user.admin?
        when :destroy
            @user.admin?
        when :export
            @user.admin?
        when :history
            @user.admin?
        when :show_in_app
            @user.admin?
        else
            raise ::Pundit::NotDefinedError, "unable to find policy #{action} for #{record}."
        end
    end

end

还有我的 rails_admin 初始值设定项的片段：

RailsAdmin.config do |config|
  config.authorize_with :pundit
  config.current_user_method(&:current_user)
  ...
end

所以现在当我加载管理仪表板时 (url: "/admin") 我得到这个错误:

undefined method `policy' for #RailsAdmin::MainController:0x0055914e2523a0>

我已按照所有说明进行操作，但仍然看不出缺少什么。任何 answer/suggestion 将不胜感激。

这也困扰着我。最终找到：https://travis-ci.org/sferik/rails_admin/jobs/152180750

rails_admin 现在默认为 ::ActionController::Base

要修复，请将以下内容放入 rails_admin.rb：

config.parent_controller = '::ApplicationController'

Rails_admin and pundit: undefined method `policy' for #<RailsAdmin::MainController
