Please note, I already have done

pip install qrcode

pip install qrcode[pil]

pip install PyQRCode

models.py code from qr app is as follows

 from django.db import models
from django import forms
from user.models import User
import datetime

# Class name starts with capital letter
class QR(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    description = models.CharField(max_length=255, blank=True)
    qr_identifier = models.CharField(max_length=255, blank=True)
    size = models.FloatField(default=0.0, blank=True)
    active = models.BooleanField(default=True, help_text='Active / Inacitve.')
    # TODO: Remove the default=1 parameter
    created_by_user = models.ForeignKey(User, on_delete=models.CASCADE, default=1)
    created_at = models.DateTimeField(editable=False, auto_now_add=True)
    

class QRFile(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    location = models.FileField(upload_to='documents/')
    size = models.CharField(max_length=200, null=True, blank=True)
    media_type = models.CharField(max_length=200, null=True, blank=True)
    qr = models.ForeignKey(QR, on_delete=models.CASCADE)

class QRURL(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    URL = models.CharField(max_length=200, null=True, blank=True, default="Product Link")
    qr = models.ForeignKey(QR, on_delete=models.CASCADE)
    
class QRScan(models.Model):
    name = models.CharField(max_length=200, null=True, blank=True)
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    qr = models.ForeignKey(QR, on_delete=models.CASCADE)
    scanned_at = models.DateTimeField(editable=False, default=datetime.datetime.now)
    comment = models.CharField(max_length=255, null=True, blank=True)

Answer 1

Your project is called qrcode and since default path for settings module of Django is

<project name>.settings

which in your case translates to

qrcode.settings

Django is importing settings from qrcode library. To fix this issue, rename your project to something that does not conflict with the library name.

After you manually rename the project, you have to make appropriate changes in manage.py and wsgi.py files.
