README Apartment App

Rails API Configuration

Add RSpec dependencies✅

bundle add rspec-rails
rails generate rspec:install

Create a User model via Devise and add appropriate configurations✅

Add devise dependencies

bundle add devise
rails generate devise install
rails generate devise User
rails db:migrate

Add code to config/environments/development.rb

config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }

Replace code in config/initializers/devise.rb

# find this line:
config.sign_out_via = :delete
# and replace it with this:
config.sign_out_via = :get

Create registrations and sessions controllers to handle sign ups and logins

rails generate devise:controllers users -c registrations sessions

Replace code in app/controllers/users/registrations_controller.rb

class Users::RegistrationsController < Devise::RegistrationsController
  respond_to :json
  def create
    build_resource(sign_up_params)
    resource.save
    sign_in(resource_name, resource)
    render json: resource
  end
end

Replace code in app/controllers/users/sessions_controller.rb

class Users::SessionsController < Devise::SessionsController
  respond_to :json
  private
  def respond_with(resource, _opts = {})
    render json: resource
    end
  def respond_to_on_destroy
    render json: { message: "Logged out." }
  end
end

Update devise routes: config/routes.rb

Rails.application.routes.draw do
  devise_for :users,
  path: '',
    path_names: {
      sign_in: 'login',
      sign_out: 'logout',
      registration: 'signup'
    },
    controllers: {
      sessions: 'users/sessions',
      registrations: 'users/registrations'
    }
  end

Configure CORS✅

Update config/initializers/cors.rb

Rails.application.config.middleware.insert_before 0, Rack::Cors do
  allow do
    origins 'http://localhost:3001'
    resource '*',
    headers: ["Authorization"],
    expose: ["Authorization"],
    methods: [:get, :post, :put, :patch, :delete, :options, :head],
    max_age: 600
  end
end

Uncomment this from Gemfile

gem "rack-cors"

Add JWT dependencies and configurations✅

Install dependencies

bundle add devise-jwt

Create Jwt secret key

bundle exec rails secret

Run this command to open the window to add the new secret key

EDITOR="code --wait" bin/rails credentials:edit

Add the secret key below the secret key base using this code

jwt_secret_key: <newly-created secret key>

In the terminal hit 'control + c' to save the file

If you get an error saying it didn't save. Manually save the file with 'command + s' in the VScode window

Add this to config/initializers/devise.rb

config.jwt do |jwt|
  jwt.secret = Rails.application.credentials.jwt_special_key
  jwt.dispatch_requests = [
    ['POST', %r{^/login$}],
  ]
  jwt.revocation_requests = [
    ['DELETE', %r{^/logout$}]
  ]
  jwt.expiration_time = 5.minutes.to_i
end

Add JWT revocation✅

Run this in the terminal

rails generate model jwt_denylist

Add this code to the migration: db/migrate/

def change
  create_table :jwt_denylist do |t|
    t.string :jti, null: false
    t.datetime :exp, null: false
  end
  add_index :jwt_denylist, :jti
end

Migrate

rails db:migrate

Replace this in the app/models/user.rb

devise :database_authenticatable, :registerable, :recoverable, :rememberable, :validatable, :jwt_authenticatable, jwt_revocation_strategy: JwtDenylist

Rails Apartment Model

Generate Model

Generate model in the terminal

rails generate resource Apartment street:string unit:string city:string state:string square_footage:integer price:string bedrooms:integer bathrooms:float pets:string image:text user_id:integer

Define the relationship between Apartment and the User in app/models/user.rb

class User < ApplicationRecord
  devise :database_authenticatable, :registerable,
  :recoverable, :rememberable, :validatable, :jwt_authenticatable, jwt_revocation_strategy: JwtDenylist
  has_many :apartments
end

Define the relationship between Apartment and the User in app/models/apartment.rb

class Apartment < ApplicationRecord
  belongs_to :user
end

Add a global variable for user to allow for easier testing in spec/models/apartment_spec.rb

require 'rails_helper'

RSpec.describe Apartment, type: :model do
  let(:user) { User.create(
      email: 'test@example.com',
      password: 'password',
      password_confirmation: 'password'
    )
  }

Add first test to test for valid attributes

it 'is valid with valid attributes' do
apartment = user.apartments.create(
street: 'Test Street',
unit: 'Test Unit',
city: 'Test City',
state: 'Test State',
square_footage: 1000,
price: '$1000',
bedrooms: 1,
bathrooms: 1.0,
pets: 'Test Pets',
image: 'https://c8.alamy.com/comp/B0RJGE/small-bungalow-home-with-pathway-in-addlestone-surrey-uk-B0RJGE.jpg',
)
expect(apartment).to be_valid
end

Add test for validating presence of attributes repeat for each data column making sure to update the it statement and the expect statement

it 'is not valid without a street attribute' do
apartment = user.apartments.create(
unit: 'Test Unit',
city: 'Test City',
state: 'Test State',
square_footage: 1000,
price: '$1000',
bedrooms: 1,
bathrooms: 1.0,
pets: 'Test Pets',
image: 'https://c8.alamy.com/comp/B0RJGE/small-bungalow-home-with-pathway-in-addlestone-surrey-uk-B0RJGE.jpg',
)
expect(apartment).not_to be_valid
expect(apartment.errors[:street].first).to eq("can't be blank")
end
end

Add validation to app/models/apartment.rb

class Apartment < ApplicationRecord
  belongs_to :user
  validates :street, :unit, :city, :state, :square_footage, :price, :bedrooms, :pets, :bathrooms, :image, presence: true
end

API Endpoints

Testing

Add a global user variable for the test file

RSpec.describe "Apartments", type: :request do
  let(:user) { User.create(
      email: 'test@example.com',
      password: 'password',
      password_confirmation: 'password'
    )
  }

Add a mock GET request for index

describe 'GET #index' do
    it 'returns a list of apartments and http success' do
      apartment = user.apartments.create(
        street: 'Test Street',

        city: 'Test City',
        state: 'Test State',
        square_footage: 1000,
        price: '$1000',
        bedrooms: 1,

        pets: 'Test Pets',
        image: 'https://c8.alamy.com/comp/B0RJGE/small-bungalow-home-with-pathway-in-addlestone-surrey-uk-B0RJGE.jpg'
      )
      get apartments_path
      expect(response).to have_http_status(200)
      expect(apartment).to be_valid
    end

Add a mock POST request for create

          unit: 'Test Unit',
          city: 'Test City',
          state: 'Test State',
          square_footage: 1000,
          price: '$1000',
          bedrooms: 1,
          bathrooms: 1.0,
          pets: 'Test Pets',
          image: 'https://c8.alamy.com/comp/B0RJGE/small-bungalow-home-with-pathway-in-addlestone-surrey-uk-B0RJGE.jpg',
          user_id: user.id
        }
      }
      apartment = Apartment.where(street: 'Test Street').first
      expect(response).to have_http_status(200)
      expect(apartment).to be_valid
    end
    it 'creates a invalid apartment' do
      post apartments_path, params: {
        apartment: {
          street: nil,

      expect(response).to have_http_status(422)
      expect(apartment).to eq(nil)
