Django error: type object 'HttpRequest' has no attribute 'META'

I am new to django. I am coding a urlshortner now I wanted to ad functionality to read Http referer to count number of times the link has been clicked from various social platforms.

In documentation it states that HttpRequest object that in included in django.http will extract it using - HttpRequest.META['HTTP_REFERER']

So I did this to print out the type of info that it contains - 

from django.http import HttpRequest
from .models import UrlSave

def display(request,id):
    print(HttpRequest.META['HTTP_REFERER'])
    try:
        short_url = UrlSave.objects.get(pk=id)
        visit_time = short_url.times_visited
        short_url.times_visited = short_url.times_visited+1
        url = short_url.to_view
        short_url.save()
        context = {'visit':visit_time,'url':url}
        return render(request,'shorturl/previsit.html',context)
    except:
        return HttpResponse('Wrong Url')

But when I visit the link it prints out the error in CLI - AttributeError: type object 'HttpRequest' has no attribute 'META'

I am unable to find out the reason for it even after going through many stackoverflow pages Please Help

You can not obtain the META of the request by accessing it like a class attribute, the specific request is the request parameter, so you can access it with request.META['HTTP_REFERER']:

from django.http import HttpRequest
from .models import UrlSave

def display(request, id):
    print(request.META['HTTP_REFERER'])
    try:
        short_url = UrlSave.objects.get(pk=id)
        visit_time = short_url.times_visited
        short_url.times_visited = short_url.times_visited+1
        url = short_url.to_view
        short_url.save()
        context = {'visit':visit_time,'url':url}
        return render(request,'shorturl/previsit.html',context)
    except:
        return HttpResponse('Wrong Url')
