Why i'm facing that error?

You have a module `Product` somewhere and it shadows your activerecord model. Rename one of them. — Sergio Tulentsev, Dec 22 '17 at 07:24
The `Product` model generated using `rails g model` command or you have manually created it? — Muhammed Anees, Dec 22 '17 at 09:38

I suppose you are getting this error because your app name will also be Product. By default your app name will be a reserved keyword and you cannot use it for naming. If this is the case, you should rename the app to something like product_app to use model name as Product. To rename the app you can refer Renaming a Rails 4 app or How to rename a rails 5 application?. Hope this help.

You need to force to require model product.rb because not auto loading this file on controller like

require 'product.rb'

Very good explanation on @shingara answer

I think you dont have the model class :

file app/model/product.rb

class Product < ApplicationModel
end
