Hello
I have simple application which checks for username and password in
database as well as looks in session for key "user_id". If user exists and
login gets successfull then page is redirected to admin page. Here problem
is I am storing username in session in one view and retrieving it another
but at the time of retrieval it says that the key does not exist in
session.
I have just started learning Django and this is my first project. Please
help me.
Here is my views.py :
====================================================================================================
# Create your views here.
from BaseHTTPServer import BaseHTTPRequestHandler
from django.shortcuts import render_to_response
from django.http import HttpResponse, HttpResponseRedirect
from django.views.decorators.csrf import csrf_exempt
from webapp.models import User
def index(request):
if request.session.get("user_id", False):
print "Used logged in"
return HttpResponseRedirect("webadmin")
else:
print "Used not logged in"
return render_to_response("index.html", {})
@csrf_exempt
def login(request):
username = request.POST.get("username", None)
password = request.POST.get("password", None)
vals = {}
if not username or not password:
print "Please enter credentials"
vals['error'] = "Invalid credentials"
return HttpResponseRedirect("/")
elif not isUserExists(username, password):
print "Invalid credentials"
vals['error'] = "Invalid credentials"
return HttpResponseRedirect("/")
else:
request.session['user_id'] = username
request.session.save()
request.session.modified = True
print "&&&&&&&&&&&&&&&&& : " + request.session['user_id']
print "Sessino value written"
return HttpResponseRedirect("webadmin")
def webadmin(request):
'''
Controller to handle /webadmin url
'''
return render_to_response("admin.html", {})
def isUserExists(uname, pwd):
'''
Check if user exists in database or not
'''
users = User.objects.filter(username=uname, password=pwd)
if len(users) >0:
print "Access granted"
return True
else:
print "Access denied"
return False
