How to explicitly specify PARTITION in ActiveRecord SELECT query?

I have a huge partitioned table and I know partition name in advance before executing SELECT query.

In vanilla SQL the syntax is SELECT * FROM objects PARTITION (p1)

My current workaround seems to be working but looks kind of hacky:

active_record_relation.to_sql.gsub('FROM `objects`', "FROM `objects` PARTITION(#{explicit_partition_name})")

I'm wondering if there is a more idiomatic ActiveRecord solution to this?

Just to be clear, I'm aware of Partition Pruning but I can't use it, because partition hashing/finding logic is an external component/system.

The database is MySQL if that's important.
