A huge "memleak" in a simple Django view

views.py

from django.http import HttpResponse
 
from .models import FirstModel

# this view will make crazy use of the RAM ;)
def my_view(request):
    # this queryset contains about 100k records
    # each of them has many ForeignKeys to other models
    huge_queryset = FirstModel.objects.all()
    
    f = open('dumb.dump', 'w')
    
    for record in huge_queryset:
        print >>f, record
 
    f.close()
    return HttpResponse('Dumb dump completed!')
