• 嘿，伙计们，我试图建立测试我的控制器使用rspec，我有3个模型和控制器，即用户，支付和家庭-这些模式;在搜索中以支付属于用户和家庭、家庭有多个支付、用户有多个支付的方式相关联。

• 我已经设法为模型的这些关联编写了测试，现在我被控制器卡住了。

• 下面是我试着写的

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

• 并得到这个错误下面在控制台.我认为问题可能与关联

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>'

• 下面是我的控制器，这是试图测试

# frozen_string_literal: true

module Api
  module V1

      before_action :set_payment, only: %i[show edit update destroy]

      def index
        if user_signed_in?
          @payments = current_user.payments.order(created_at: :desc)
          render json: @payments.to_json(include: %i[home user])
        else
          render json: {}, status: 401
        end
      end

      # GET /payments/1 or /payments/1.json
      def show
        @payment = current_user.payments.find(params[:id])

      end

      end

      private

      def set_payment

      end

      # Only allow a list of trusted parameters through.
      def payment_params
        params.require(:payment).permit(:first_name, :last_name, :phone_number, :address, :money_paid, :date,
