#visible_to(user) ⇒ Object

NOTE: in ActiveRecord 2.x #visible_to was mixed into class ActiveRecord::NamedScope::Scope but with AREL scope it must be Array.

The following is used to filter out user activities based on activity subject’s permissions. For example:

Note that we can’t use named scope for the Activity since the join table name is based on subject type, which is polymorphic.
