Тестирование запросов с помощью rspec

• Привет, ребята, я пытаюсь создать тесты для своих контроллеров с помощью rspec, у меня есть 3 модели и контроллеры, т.е. пользовательский, платежный и домашний -Эти режимы связаны в поиске таким образом, что платеж принадлежит пользователю и дому, дом имеет много платежей, а пользователь имеет много платежей.

-Мне удалось написать тесты для этих ассоциаций для моделей, теперь застрял на контроллерах.

• Ниже то, что я пытался написать

require 'rails_helper'

RSpec.describe 'Payments', type: :request do
  let(:valid_attributes) do
    { first_name: 'mutebi', last_name: 'godfrey', phone_number: '+256780140670', address: 'kampala', money_paid: '6000', date: '25/08/2023',
      nin_number: 'KK45896587450P', user_id: '5', home_id: '9' }
  end

  let(:invalid_attributes) do
    skip('Add a hash of attributes invalid for your model')
  end

  describe 'GET /index' do
    it 'renders a successful response' do
      Payment.create! valid_attributes
      get payments_url, headers: valid_headers, as: :json
      expect(response).to be_successful
    end
  end

  describe 'GET /show' do
    it 'renders a successful response' do
      payment = Payment.create! valid_attributes
      get payment_url(payment), as: :json
      expect(response).to be_successful
    end
  end
end

• и получить эту ошибку ниже в консоли. я думаю проблема может быть в ассоциациях

  1) Payments GET /index renders a successful response
     Failure/Error: Payment.create! valid_attributes
     
     ActiveRecord::RecordInvalid:
       Validation failed: User must exist, Home must exist
     # ./spec/requests/payments_spec.rb:17:in `block (3 levels) in <main>'

  2) Payments GET /show renders a successful response
     Failure/Error: payment = Payment.create! valid_attributes
     
     ActiveRecord::RecordInvalid:
       Validation failed: User must exist, Home must exist
     # ./spec/requests/payments_spec.rb:25:in `block (3 levels) in <main>'

• Ниже мой контроллер, который я пытаюсь проверить
