[Mustaballer]

Overview

• Resolves #
• add QR code scanner support
• admins can scan QR codes, and participants that have accepted and rsvped can view thier QR codes

Unit Tests Created

• n/a

Steps to QA

• run migrations with python manage.py migrate
• create an admin user and log in to localhost:8000 --> you should be able to view admin dashboard
  • click on qr code scanning, this should take you to qr scanning page
  • currently there is no active event, in order for scanning to be active you need to update the EVENT_START_DATE = datetime(2024, 10, 26, 8, 0, 0, tzinfo=TZ_INFO) to earlier so you can test it and adjust one of these sign in event start dates to your current time so its active following in settings/__init__.py

SIGN_IN_TIMES = [
{
"name": "sign_in",
"description": "Hackathon Sign In",
"time": datetime(2023, 11, 4, 10, 0, 0, tzinfo=TZ_INFO), # Nov 4th @ 9am
},
{
"name": "lunch1",
"description": "Lunch Day 1",
"time": datetime(2023, 11, 4, 12, 30, 0, tzinfo=TZ_INFO), # Nov 4th @ 12:30pm
},
{
"name": "dinner1",
"description": "Dinner Day 1",
"time": datetime(2023, 11, 4, 18, 0, 0, tzinfo=TZ_INFO), # Nov 4th @ 6pm
},
{
"name": "breakfast2",
"description": "Breakfast Day 2",
"time": datetime(2023, 11, 5, 8, 0, 0, tzinfo=TZ_INFO), # Nov 5th @ 8am
},
{
"name": "lunch2",
"description": "Lunch Day 2",
"time": datetime(2023, 11, 5, 11, 45, 0, tzinfo=TZ_INFO), # Nov 5th @ 11:45pm
},
]```

• In order to test scanning a QR code you need a QR code --> first create a user with an application who has been accepted and has rsvp(ask me if you don't know how to do this), sign in to dashboard and it should have QR code
• then just go to admin site and show off this QR code(i made a screenshot of the QR code and then showed to the scanner)
• it should work and give details of your dietary requirements and t shirt size

SIGN_IN_TIMES needs to be updated with the correct times

[Mustaballer]

@carmen-chau double check if these intervals work

[Mustaballer]

this might be better

UPDATE: From logistics, I think the only time slot we need to adjust is Lunch Day 2

In __init__.py, around line 354, replacing the line with this should work:

"time": datetime(2024, 10, 26, 11, 45, 0, tzinfo=TZ_INFO), # Oct 26th @ 11:45 pm

Basically the table should look like this now, lmk if there any differences on your end:

I tried adding the additional dietary restriction info on my end, you can try doing this:

return_string = ( (user.first_name).capitalize() + " successfully signed in. 👕T-shirt: " + application.tshirt_size + " 🍉 Dietary Restrictions: " + application.dietary_restrictions + " 🍉 Extra dietary notes: " + application.free_response_dietary_restrictions )

application.free_response_dietary_restrictions is not blank only if the user has either allergies or has written "Other" in application.dietary_restrictions

Another note: one thing I'm slightly concerned about is spacing (100 char max for application.free_response_dietary_restrictions)
