ruby on rails - ActiveRecord is not reloading nested object after it's updated inside a transaction -

i'm using rails 4 oracle 12c , need update status of user, , use new status in validation model need update:

class user   has_many :posts    def custom_update!(new_status)     relevant_posts = user.posts.active_or_something     activerecord::base.transaction       update!(status: new_status)       relevant_posts.each { |post| post.update_stuff! }     end   end end  class post   belongs_to :user    validate :pesky_validation    def update_stuff!     # can call other places, need transaction here     activerecord::base.transaction       update!(some_stuff: 'some value')     end   end    def pesky_validation     if user.status == old_status       errors.add(:base, 'nope')     end   end end 

however, failing , receive validation error pesky_validation, because user inside post doesn't have updated status.

the problem is, when first update user, instantiated users inside relevant_posts variable not yet updated, , i'd need fix call reload, however, maybe because i'm inside transaction, not working, , pesky_validation failing.

relevant_users.first.user.reload, example, reloads user same old status had before update, , i'm assuming it's because transaction not yet committed. how can solve , update references new status?
