I'd like to try and revive discussion around these issues: https://github.com/rails/rails/issues/7121 https://github.com/rails/arel/issues/83
Originally, my thought for an easy solution was to hide the presence of group_values inside a subquery using `from(relation.group(x)).count` as I suggested here: https://groups.google.com/forum/#!topic/rubyonrails-core/mwBehQcEduU SELECT COUNT(*) FROM (SELECT * FROM ... GROUP BY ...) Unfortunately some databases (MySQL) are really inefficient at dealing with functions on subqueries like this. And ultimately, relying on subqueries to fix it for us is a hack just to get around the problem with blindly calling `count` and expecting an integer. I keep running into this problem regularly enough that I really want to work something out for separate and predictable "row count" and "grouped count" methods. Maybe something like one of these ideas I sketched out: https://gist.github.com/avit/3681183 Is there a way forward?
