How to set or get a cookie value in django

Question

This is my code:

from django.shortcuts import render_to_response, get_object_or_404 from django.template import RequestContext from django import http from django.http import HttpResponse   def main(request, template_name='index.html'):     HttpResponse.set_cookie('logged_in_status', 'zjm1126')     context ={               'a':a,               'cookie':HttpResponse.get_cookie('logged_in_status'),     }      return render_to_response(template_name, context)     #return http.HttpResponsePermanentRedirect(template_name) 

It raises this exception:

unbound method set_cookie() must be called with HttpResponse instance as first argument (got str instance instead) 

What can I do?

Answer 1

You can't just start calling methods on the HttpResponse class, you have to instantiate it e.g. response = HttpResponse("Hello World"), call the cookie method, and then return it from your view.

response = render_to_response(template_name, context)  response.set_cookie('logged_in_status', 'never_use_this_ever')  return response # remember my other answer:  # it's a terrrible idea to set logged in status on a cookie. 

To get the cookie:

request.COOKIES.get('logged_in_status')  # remember, this is a terrible idea.
