undefined method `will_save_change_to_address

I am new to coding and a friend and I are making a website that has a map with markers. For some reason it's working when she pulls the master branch but when I pull origin master on GitHub I get errors and no markers. Does anyone know why it works on one devise but not on another? We have been constantly running into this issue.

product model

class Product < ApplicationRecord
  belongs_to :user
  has_many :bookings, dependent: :destroy
  validates :name, presence: true
  validates :category, presence: true
  has_one_attached :photo
  geocoded_by :address
  after_validation :geocode, if: :will_save_change_to_address?
  include PgSearch::Model
  pg_search_scope :search_by_name_and_category,
  against: [ :name, :category ],
  using: {
    tsearch: { prefix: true } # <-- now `superman batm` will return something!
  }
end

product controller

def index
    if params[:query].present?
      @products = Product.search_by_name_and_category(params[:query])
    else
      @products = Product.all
      @markers = @products.geocoded.map do |product|
        {
          lat: product.latitude,
          lng: product.longitude
        }
      end
    end
  end

  def product_params
    params.require(:product).permit(:name, :category, :price, :description, :address)
  end
