我尝试使用 rails_admin 的示例初始化程序将 piggybak 集成到我的 rails 应用程序中

https://github.com/piggybak/demo/blob/master/config/initializers/rails_admin.rb

当我尝试启动服务器时,出现以下错误:

/home/dumand/Desktop/Projects/3dgreen/config/initializers/rails_admin.rb:32:in nestable block (2 levels) in <top (required)>': undefined method' 用于 RailsAdmin::Config::Actions:Module (NoMethodError)

这是服务器日志:

这是 rails_admin 初始化程序:

RailsAdmin.config do |config|

  config.main_app_name = ["3D Green"]

  ### Popular gems integration

  ## == Devise ==
  # config.authenticate_with do
  #   warden.authenticate! scope: :user
  # end
  # config.current_user_method(&:current_user)

  ## == Cancan ==
  # config.authorize_with :cancan

  ## == PaperTrail ==
  # config.audit_with :paper_trail, 'User', 'PaperTrail::Version' # PaperTrail >= 3.0.0

  config.actions do
    dashboard                     # mandatory
    index                         # mandatory
    new
    export
    bulk_delete
    show
    edit
    delete
    show_in_app

   nestable do
    visible do
      [::PiggybakTaxonomy::NavigationNode].include? bindings[:abstract_model].model
    end
   end

    ## With an audit adapter, you can add:
    # history_index
    # history_show

    config.model Product do
      edit do
      include_all_fields
      end
    end

  end
end

尝试删除可嵌套的分类代码,因为您似乎也没有根据您的模型使用嵌套分类
