I'm trying to send users a new notification when a person follows them. But, I receive an error when the acts_as_notifable method fires off. The relationship is 1 to 1, but I would also be alright with grouping follow notifications as well. The code that I have is below. No notifications are fired off.

follow.rb

class Follow < ActiveRecord::Base



  extend ActsAsFollower::FollowerLib

  extend ActsAsFollower::FollowScopes



  # NOTE: Follows belong to the "followable" and "follower" interface

  belongs_to :followable, polymorphic: true

  belongs_to :follower, polymorphic: true



  acts_as_notifiable :users, targets: -> (follow, key) do

   ([follow.user.followable_id] - [follow.user.follower_id])

  end



end

schema

  create_table "follows", force: :cascade do |t|

    t.string "followable_type", null: false

    t.bigint "followable_id", null: false

    t.string "follower_type", null: false

    t.bigint "follower_id", null: false

    t.boolean "blocked", default: false, null: false

    t.datetime "created_at", null: false

    t.datetime "updated_at", null: false

    t.index ["followable_id", "followable_type"], name: "fk_followables"
