Rails_admin和pundit:#RailsAdmin :: MainController的未定义方法`policy'

Question

我正在使用rails 5,我正在尝试使用pundit为我的rails_admin面板实现授权.所以我在我的应用程序控制器中包含了pundit并安装了rails_admin_pundit gem,你可以在我的Gemfile的这个片段中看到:

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初始化程序的片段:

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(url:"/ admin")时,我收到此错误:

#RailsAdmin :: MainController的未定义方法`policy':0x0055914e2523a0>

我遵循了所有的指示,但我仍然没有看到缺少的东西.任何答案/建议将不胜感激.

这也让我感到烦恼.最终发现:https://travis-ci.org/sferik/rails_admin/jobs/152180750

rails_admin现在默认为 ::ActionController::Base

要修复,请将以下内容放在rails_admin.rb中:

config.parent_controller = '::ApplicationController'
