Dzięki za rozwiązanie, wszystko działa okej 👍 Dla przyjemniejszego developmentu można dodać seedy, które odpala się komendą rails db:seed:
# db/seeds.rb
puts 'Creating customers'
customers = []
10.times do
customers << Customer.create!(name: Faker::LordOfTheRings.character)
end
puts 'Creating categories'
categories = []
5.times do
categories << Category.create!(name: Faker::GameOfThrones.house)
end
puts 'Creating products'
products = []
20.times do
products << categories.sample.products.create!(price: rand(1..10_000))
end
puts 'Ordering products'
products.sample(15).each do |product|
product.update!(customer: customers.sample)
end
puts 'Done!'|

Zazwyczaj pisze się:
@customer = Customer.new(customer_params)
if @customer.save
...| class ProductsController < ApplicationController | ||
| def index | ||
| @customer = Customer.find(params[:customer_id]) | ||
| @products = @customer.products.order(price: :desc) |

order(price: :desc) mogłoby stać się scope na modelu Product

brak opcji optional: true powoduje, że nie można stworzyć produktu, który nie jest jeszcze przypisany do żadnego customera
