[英]how to add sorted elements in the filter dropdown in activeadmin rails
I have a Post model, PostSource model. 我有一个Post模型,PostSource模型。 A PostSource has many posts, a post belong to one PostSource.
PostSource有很多帖子,帖子属于一个PostSource。
Using ActiveAdmin, in the Index action of the Post, I am displaying a filter of PostSource this way: 使用ActiveAdmin,在Post的Index操作中,我以这种方式显示PostSource的过滤器:
filter :post_source, label: 'Source'
filter :category, as: :select, collection: Category.order(:name).collect { |cat| [cat.name, cat.id] }
with the controller as: 与控制器一样:
controller do
def scoped_collection
end_of_association_chain.includes(:post_source)
end
end
It displays the source, but does not display in a sorted order. 它显示源,但不按排序顺序显示。 How to sort the filter in this case?
在这种情况下如何对过滤器进行排序?
I tried adding sortable, order on filter but it does not seem to work 我尝试在过滤器上添加可排序的顺序,但它似乎不起作用
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. 如果您正在尝试对第一个过滤器('post_source')进行排序,您可以像在第二行中一样添加一个集合,然后在一个块中进行排序。
filter :post_source, label: 'Source', collection: proc { PostSource.order(:name) }
This syntax might be used as an alternative in the second example as well. 此语法也可以在第二个示例中用作替代方法。
