t = Topic.objects.get_or_create(top_name=random.choice(topics))[0]
t.save()
return t

def populate(N=5):

for entry in range(N):

# iget the topic for the entry
top = add_topic()

# create fake data for that entry
fake_url = fakegen.url()
fake_date = fakegen.date()
fake_name = fakegen.company()

# create the new Webpage entry
webpg = Webpage.objects.get_or_create(Topic=top,url=fake_url,name=fake_name)[0]

# create fake access record for Webpage
acc_rec = AccessRecord.objects.get_or_create(name=webpg,date=fake_date)[0]
if __name__=='__main__':
print("populating script")
populate(20)
