Active Record .push() problem


I have code like this

  def items
    my_items = self.items
    if self.added_items
      self.added_items.each do |ai|
    return my_items


the added items are a join table when you connect to other users
items. Then im trying to display the complied list. but when doing
this, it changes the user_id of the added item from the user that
created to the current_user.

not fully understanding why, or if there is a better way to handle

any help would be greatly appreciated.
