undefined method `will_save_change_to_address - ruby-on-rails-3

Question

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

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

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

Method will_save_change_to_address? comes from the Rails method will_save_change_to_attribute? . You get an error, because your Product model is missing address attribute. Just create a migration adding this column to the products table.
