Tutorial 1

• django-admin startproject polls - create a new django project named polls
• python manage.py startserver - start web app on localhost

Creating a new view

1. pollsapp/views.py - define index(request)
2. pollsapp/urls.py - add url for view here

urlpatterns = [
        path('', views.index, name='index'),
        ]

3. pollsproject/urls.py - add rootURL conf herer

urlpatterns = [
    path('pollsapp/', include('pollsapp.urls')), # new url
    path('admin/', admin.site.urls),
]

The path function here takes four arguments - route: string containing URL pattern - view: function to be called when pattern is matched - name: unique identifier for URL

Tutorial 2

• INSTALLED_APPS in settings.py holds list of all django applications that are activated
• python manage.py createsuperuser - create new admin
• pollsapp/admin.py - contains models we want to be displayed in our admin interface

from django.contrib import admin

from .models import Question

admin.site.register(Question)

Making model changes

• Change your models (in models.py).
• Run python manage.py makemigrations to create migrations for those changes
• Run python manage.py migrate to apply those changes to the database.
