如何在activeadmin rails的过滤器下拉列表中添加排序的元素 [英] how to add sorted elements in the filter dropdown in activeadmin rails

问题描述

我有一个Post模型，PostSource模型。一个PostSource有很多帖子，一个帖子属于一个PostSource。

I have a Post model, PostSource model. A PostSource has many posts, a post belong to one PostSource.

使用ActiveAdmin，在Post的Index操作中，我以这种方式显示PostSource的过滤器： / p>

Using ActiveAdmin, in the Index action of the Post, I am displaying a filter of PostSource this way:

filter :post_source, label: 'Source'
filter :category, as: :select, collection: Category.order(:name).collect { |cat| [cat.name, cat.id] }

，控制器为：

controller do
  def scoped_collection
    end_of_association_chain.includes(:post_source)
  end
end

它显示源，但不按排序顺序显示。在这种情况下如何对过滤器进行排序？

It displays the source, but does not display in a sorted order. How to sort the filter in this case?

我尝试在过滤器上添加可排序的订单，但似乎不起作用

I tried adding sortable, order on filter but it does not seem to work

推荐答案

如果您要对第一个过滤器（ post_source）进行排序，则只需在第二行中添加一个集合，然后在一个块内进行排序即可。

If you're trying to sort the first filter ('post_source'), you could just add a collection as you have in your second line, and sort within a block.

filter :post_source, label: 'Source', collection: proc { PostSource.order(:name) }

第二个示例中也可以使用此语法。

This syntax might be used as an alternative in the second example as well.
