The management command "startapp" can be used to create the skeleton of the new app:

python manage.py startapp samples

Then the normal duties are required to integrate the new app in the project:

• add "samples" to INSTALLED_APPS list (in settings)
• provide a default "index" view to the new app
• create a suitable urls.py in the app
• include samples.urls in the general (project's) url route

Hint: this app will be very similar to the "chat" app

howto create a Model

At this moment "samples" will require a single model; for example:

class Sample(models.Model):
    id = models.UUIDField(default=uuid.uuid4, primary_key=True, unique=True, null=False, blank=False, editable=False)
    date = models.DateTimeField(auto_now_add=True)
    value = models.FloatField(default=0.0)

Having created a new Model, we need to generate a new migration:

python manage.py makemigrations sample

and run it to update the database structure:

python manage.py migrate

These steps needs to be repeated every time a Model in created or modified

Purpose

• add a new page di the "frontend" app
• each time the page is show, a new random UUID is shown

Hint: in python you can obtain a random UUID as follows:

import uuid
new_uuid = str(uuid.uuid4())

Optional

• provide an input field to let use ask for more N uuids, where N >= 1
