Replacement for “has_many … counter_sql” in Rails 4.1


I’m looking for ways to replace “has_many … counter_sql: ‘…’” in order to migrate an app from Rails 3.2 to 4.0 (done) and then up to 4.1 which has dropped support for “counter_sql”. An example is on Stackoverflow:

I’d do it with a separate counter method, but it doesn’t feel like the ideal solution.

Thanks for your hints!

my guess would be an association extension - i put more details on your stack overflow question.
