'ruby how properly update parent and child object

I have tree related models:

class Parent < ApplicationRecord
  has_many :pets
  has_one :kid
  attr_accessor :notify_kid
  after_save :let_the_kid_know

  def let_the_kid_know
    if notify_kid == '1'
       self.kid.does_the_kid_know = true
       self.kid.save
    end
  end
end

class Pet < ApplicationRecord
  belongs_to :parent
end

class Kid < ApplicationRecord
  belongs_to :parent
end

In my test I try to do something like this:

 parent.notify_kid = '1'
 parent.pets.first.name = 'Lollipop'
 parent.save!

 assert_equal true, parent.kid.does_the_kid_know

Test fails. Additionally, the pet item doesn't update either. In the test, I operate on objects already created in the database.

Solution 1:[1]

There is a syntax error here: def let_the_kid_know:, it should be def let_the_kid_know and another parent.notife_kid I guess is parent.notify_kid.

If that is not enough to fix you problem please post the error you see in the terminal.
