There was a problem hiding this comment.
Since the fix is not implemented yet, this spec fails:
1) ActiveAdmin::Views::PaginatedCollection creating with the dsl with :pagination_total set to false should not perform count queries
Failure/Error: end
expected "D, [2018-04-02T22:48:21.957729 #82970] DEBUG -- : \e[1m\e[35m (0.2ms)\e[0m \e[1m\e[34mSELECT COUN...T 1 FROM \"posts\" LIMIT ? OFFSET ?) subquery_for_count\e[0m [[\"LIMIT\", 30], [\"OFFSET\", 0]]\n" not to include "SELECT COUNT"
and the log output shows the count queries:

The PR #3848 was supposed to make sure that
paginate_total: falseoption preventsSELECT COUNTqueries. Unfortunately, the current AA version (v1.2.1) makes count queries whenpaginate_total: falseis provided.The goal of this PR is to add a spec to assert on the count query and fix the issue.
