Rails_admin 和专家:#<RailsAdmin::MainController 的未定义方法`policy' [英] Rails_admin and pundit: undefined method `policy' for #<RailsAdmin::MainController

问题描述

我在 rails 5 上，我正在尝试使用专家为我的 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 rails_admin_pundit gem，正如你在我的这个片段中看到的宝石文件:

gem '设计'宝石设计-i18n"gem 'rails_admin', '~>1.0'宝石'rails_admin-i18n'宝石rails_admin_tag_list"，github:kryzhovnik/rails_admin_tag_list"宝石专家"gem "rails_admin_pundit", :github =>sudosu/rails_admin_pundit"

申请政策:

class ApplicationPolicyattr_reader :current_user, :recorddef 初始化(当前用户，记录)@user = current_user@record = 记录结尾定义索引?错误的结尾定义显示?scope.where(:id => record.id).exists?结尾定义创建?错误的结尾定义新?创造?结尾定义更新?错误的结尾定义编辑?更新?结尾def销毁?错误的结尾def rails_admin?(动作)案件诉讼什么时候:仪表板@user.admin?什么时候:索引@user.admin?什么时候:显示@user.admin?什么时候:新@user.admin?什么时候:编辑@user.admin?什么时候:销毁@user.admin?什么时候:出口@user.admin?什么时候:历史@user.admin?当:[e-mail]?别的引发 ::Pundit::NotDefinedError，无法为 #{record} 找到策略 #{action}."结尾结尾结尾

还有一段我的 rails_admin 初始值设定项:

RailsAdmin.config 做 |config|config.authorize_with :punditconfig.current_user_method(&:current_user)...结尾

所以现在当我加载管理仪表板(网址:/admin")时，我收到此错误:

<块引用>

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

我按照所有说明进行操作，但我仍然看不到缺少什么.任何答案/建议将不胜感激.

解决方案

这也困扰着我.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，请将以下内容放入 rails_admin.rb:

config.parent_controller = '::ApplicationController'

I'm on rails 5 and I'm trying to implement authorizations with pundit for my rails_admin panel. So I included pundit in my application controller and installed the rails_admin_pundit gem as you can see in this snippet of my Gemfile:

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"

The application policy:

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

And a snippet of my rails_admin initializer:

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

So now when I load the admin dashboard (url: "/admin") I get this error:

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

I followed all the instructions, but I still don't see what's missing. Any answer/suggestion will be greatly appreciated.

解决方案

This bugged me too. Eventually found: https://travis-ci.org/sferik/rails_admin/jobs/152180750

rails_admin now defaults to ::ActionController::Base

To fix, put the following in rails_admin.rb:

config.parent_controller = '::ApplicationController'
