Rails_admin 和 pundit：#

2024-05-24

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 https://github.com/sudosu/rails_admin_pundit/ 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"

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

以及我的 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（url：“/admin”）时，我收到此错误：

#RailsAdmin::MainController:0x0055914e2523a0> 的未定义方法“策略”

我遵循了所有说明，但我仍然没有看到缺少什么。任何答案/建议将不胜感激。

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

Rails_admin 现在默认为::ActionController::Base

要修复此问题，请将以下内容放入rails_admin.rb中：

config.parent_controller = '::ApplicationController'
