Ruby on rails 如何将作为标记的行为集成到RailsAdmin？

是否有人在RailsAdmin上充当标签？我正在努力，但对我不起作用

假设你有后模特

class Post < ActiveRecord::Base
  attr_accessible :title, :user_id, :content, :tag_list

  acts_as_taggable
end

仅此而已，以下是包含上述场景的示例项目：

有什么错误吗？我能知道什么是不起作用的吗？我曾在一些项目中尝试过这种方法。负责后端的人让它工作了很多次，但是每次rails\u管理员或rails更新，整个事情都会崩溃，失控。我强烈建议您开始考虑编写自己的后端，因为虽然rails_admin非常适合开始工作，但您越是尝试自定义它，它只会变得更加复杂和令人沮丧，而且它节省的时间与维护自定义rails_admin设置所需的时间相比变得微不足道。

config.model Post do
  list do
    field :title
    field :tag_list
  end

  edit do
    field :title
    field :tag_list do
      html_attributes do
        {:style => "width:90%"}
      end
    end
    field :content
  end
end
