Allow multi-level STI #82
Description
If you have this scenario
class User
acts_as_reader
end
class A
acts_as_readable on: :created_at
end
class A < B
end
class B < C
end
And try to do something like
user = User.create!
c = C.create!
# Assume A.last is the same record as c
a = A.last
a.mark_as_read!(for: user)
user.have_read?(c)
# Expect true, but got false
I think it has to do with readable_parent behaviour.
I made a pull request to address this issue.
