Environment setup

Create your conda environment or python venv and run the following in it. If unsure, refer to https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/.

python -m pip install -U --force-reinstall -r requirements.txt  # use pip3 for Linux
cd ascendaApp/
npm install # in ./ascendaApp

Run app locally

Run the following on separate terminals in ./ascendaApp

python manage.py runserver # django
npm start                  # react

Visit localhost:3000

Test locally

python manage.py runserver                        # run server for selenium
npx mocha src/selenium/test.js --no-timeouts      # run individual selenium test file
npx mocha src/selenium --no-timeouts --recursive  # run all selenium tests
./node_modules/.bin/jest ./src/components/        # run all unit tests

Change database models

Refer to this guide for Django-REST: https://www.digitalocean.com/community/tutorials/build-a-to-do-application-using-django-and-react

python manage.py makemigrations ascendaApp  # update migrations from Django models
python manage.py sqlmigrate ascendaApp 0001 # returns SQL from migrations
python manage.py migrate                    # apply migrations
python manage.py createsuperuser            # create admin

Experiment with django shell

python manage.py shell # run cli with django project environment

from ascendaApp.models import Hotel
from ascendaApp.views import HotelSerializer
from django.utils import timezone

Hotel.objects.all().count()
Hotel.objects.filter(name__startswith='Park').get() # __ to chain relationships, question__dat__year
Hotel.objects.get(pk=1).delete()
h7 = Hotel.objects.filter(id=7).get()
HotelSerializer(h7).data

h1 = Hotel(name='Studio M Hotel', reviewScore=3.69, price=450.0, address='3 Nanson Road', lat=1.29088, lng=103.83904)
h1.save()
h2 = Hotel(name='Park Hotel Clarke Quay', reviewScore=2.69, price=302.0, address='1 Unity Street', lat=1.29148, lng=103.8424)
h2.save()
h3 = Hotel(name='Aqueen Hotel Paya Lebar', reviewScore=4.69, price=192.0, address='33 Jalan Afifi', lat=1.32218, lng=103.89177)

sqlite3  db.sqlite3
SELECT * FROM ascendaApp_bookinginfo;
