How can I set Django Cookies

Question

I have a web site which shows different content based on a location the visitor chooses. e.g: User enters in 55812 as the zip. I know what city and area lat/long. that is and give them their content pertinent to that area. My question is how can I store this in a cookie so that when they return they are not required to always enter their zip code?

I see it as follows:

Set persistent cookie based on their area.

When they return read cookie, grab zipcode.

Hello @kartik,

This is a helper to set a persistent cookie:

import datetime

def set_cookie(response, key, value, days_expire = 7):
  if days_expire is None:
    max_age = 365 * 24 * 60 * 60  #one year
  else:
    max_age = days_expire * 24 * 60 * 60 
  expires = datetime.datetime.strftime(datetime.datetime.utcnow() + datetime.timedelta(seconds=max_age), "%a, %d-%b-%Y %H:%M:%S GMT")
  response.set_cookie(key, value, max_age=max_age, expires=expires, domain=settings.SESSION_COOKIE_DOMAIN, secure=settings.SESSION_COOKIE_SECURE or None)

Use the following code before sending a response.

def view(request):
  response = HttpResponse("hello")
  set_cookie(response, 'name', 'jujule')
  return response

Hope it helps!!
Thank you!!
