Ruby on rails Rails 3 ActiveAdmin-用于筛选器选项卡和索引数据的不同查询

我不熟悉ruby、rails和ActiveAdmin

我有一些自定义过滤器，可以返回正确的数据，并且可以在“过滤器”选项卡中看到正确数量的记录

我注意到在索引视图中实际呈现数据时使用了不同的查询，我不知道为什么

经过进一步调查，我认为我的问题与ActiveAdmin中的分页有关。我有一个特定的请求，其中我将自己的可显示广告限制设置为3，但是这个限制被ActiveAdmin中的分页操作覆盖

我尝试将paginate设置为false，但没有任何效果

# The Query should be
# [ my query is here, see image below ]) ORDER BY RANDOM() LIMIT 3

# Effect with paginate = true to my query is:
# [ my query is here, see image below ]) ORDER BY RANDOM() LIMIT 30 OFFSET 0
config.paginate = true

# Effect with paginate = false to my query is:
# [ my query is here, see image below ]) ORDER BY RANDOM() LIMIT 10000 OFFSET 0
config.paginate = false


# Expected SQL - This is what gets used on the tabs at top of screen
SELECT "advertisements".* FROM "advertisements" WHERE "advertisements"."site_section" = 'Signed In' AND "advertisements"."region_id" IN (10) AND (active = 'true' AND start_date <= '2014-12-01 13:00:00.000000' AND end_date >= '2014-12-01 13:00:00.000000') ORDER BY RANDOM() LIMIT 3


# Actual SQL - This is what is used to render the index
SELECT "advertisements".* FROM "advertisements" WHERE "advertisements"."site_section" = 'Signed In' AND "advertisements"."region_id" IN (10) AND (active = 'true' AND start_date <= '2014-12-01 13:00:00.000000' AND end_date >= '2014-12-01 13:00:00.000000') ORDER BY RANDOM() LIMIT 30 OFFSET 0

谢谢你的图片这个答案的问题是它是不可配置的，示例中返回的当前广告数量3是来自custom panel的一个查询参数。如何阻止页面与我的查询进行交互。即使关闭它也不能阻止ActiveAdmin将我的调用更改为limit。
