ActiveAdmin报表中的项目编号 [英] Numbering items in an ActiveAdmin Report

问题描述

是否可以在ActiveAdmin中获取每个项目的顺序号？

Is it possible to get the sequential number of each item in ActiveAdmin?

所以看起来像这样：

| Number | Name  |

| 1      | Bill  |

| 2      | Smith |  

我知道这可以通过 each_with_index 来实现

I know this can be achieved with each_with_index but don't think there is a way to use this with ActiveAdmin.

是否可以像 controller一样添加一些内容 c >？

我想将此功能添加到ActiveAdmin的索引中，例如

I want to add this functionality into an index on ActiveAdmin so for example

index do
   column "Number" do |a|
       # Some way of specifying index number         
   end
   column "Name" do |a|
       a.name
   end

end

谢谢

推荐答案

这是可行的：

index do
  @index = 30 * (((params[:page] || 1).to_i) - 1) # 30 needs to set to that what your page size is
  column :number do
    @index += 1
  end
end

更新：方式上有一个构建实现：

UPDATE: There is a build in implementation on the way:

index do
  selectable_column
  index_column
  column ...
end
