Rails_admin 和专家:#<RailsAdmin::MainController 的未定义方法“策略”
Rails_admin and pundit: undefined method `policy' for #<RailsAdmin::MainController
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'
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"
