Sql rails 4使用一些散列修改查询输出

这是我从查询数据库输出的示例数据

{name: "abc", product_id: 1, supplier_id: 1, supplier_name: "zxc", quantity:"40", price:"100"}

现在在rails中，可以这样修改输出

{name: "abc", product_id: 1, supplier_id: 1, details: {supplier_name: "zxc", quantity:"40", price:"100"} }

我如何做到这一点，更改一些字段并将其插入哈希，我使用它是因为它用于显示详细信息页面

非常感谢您的简单评论和回答，， 多谢各位

这是我的控制器

  def crud_show(model)
if model.methods.include?(:show)
  data = model.show(params[:id], current_holding_company.id)
else
  data = model.find_by(id: params[:id], holding_company_id)
end

if data.blank?
  render nothing: true, status: 404
else
  respond_to do |format|
    format.json { render json: data.to_json, status: 200 }
  end
end
end

这是我的模型
