        qr_image = qrcode.make(request.POST.get("http://labpys.com",""),image_factory=factory, box_size=20)    
        bufstore = io.BytesIO()

Now to set url in urls.py

from django.contrib import admin
from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include("qr_code.urls")),
]

from django.contrib import admin
from django.urls import path
from . import views

urlpatterns = [
   path("",views.qr_code,name="qrcode"),
]
