Примечание

The CounterCache behavior works for belongsTo associations only. For example for «Comments belongsTo Articles», you need to add the CounterCache behavior to the CommentsTable in order to generate comment_count for Articles table.

It is possible though to make this work for belongsToMany associations. You need to enable the CounterCache behavior in a custom through table configured in association options. See how to configure a custom join table Using the „through“ Option.
