ActiveAdmin-将范围与过滤器一起使用 [英] ActiveAdmin - Using scopes with filters

问题描述

在我的ActiveAdmin模型中，我有一个自定义范围来显示已删除的记录，还有几个过滤器用于按特定列搜索记录。

In my ActiveAdmin model I have a custom scope to show deleted records and several filters for searching records by specific columns.

单独使用过滤器或将其组合在一起可以正常使用。

Using the filters individually or combined together works as expected.

使用范围可以按预期运行。

Using a scope works as expected.

问题是，使用范围似乎会覆盖所有过滤器，并且在选择范围后，添加的任何过滤器都无济于事。

The problem is that using a scope seemingly overrides all the filters and after selecting a scope any filter added does nothing.

这里有任何想法吗？我想要的是能够显示特定范围，然后仍然能够在该范围内过滤结果。

Anyone have any ideas here? What I want is to be able to show a specific scope and then still be able to filter results within that scope.

    ActiveAdmin.register Example do
      scope :deleted do |example|
        Example.only_deleted
      end

      scope :all do |example|
        Example.with_deleted
      end

      filter :title
      filter :description

      index do
        column :title
        column :description
      end

    end

[更新]

这是我一直使用的解决方案。我在模型上设置了with_deleted范围，并在侧面包括了用于显示/隐藏已删除结果的过滤器。不理想，因为还会显示最初删除的结果，但是至少所有过滤器都可以一起使用。

Here's the solution I've gone with. I set the with_deleted scope on the model and include filter on the side for showing/hiding deleted results. Not ideal since initially deleted results are also shown, but at least all filters can be used together.

    ActiveAdmin.register Example.with_deleted do

      filter :title
      filter :description
      filter :deleted, :as => :select, :collection => {:true => nil, :false => false }

      index do
        column :title
        column :description
      end

    end

推荐答案

不是作用域，而是创建另一个过滤器，该过滤器将根据是否删除示例或所有示例来选择条件上的记录。并根据需要应用尽可能多的过滤器。

Rather than scope create another filter which will select the records on criterion based on if examples are deleted or all. And apply as many filter as you want.

或者在过滤器中，同时计算要在其上运行过滤器的选择器，并相应地运行范围，然后在该过滤器上放置条件选择器。

Or in filter while calculating the selector on which you will run the filter run the scope accordingly and then put the filter conditions on that selector.
