Retrieve datas from session after redirect

How can i retrieve the data from session within the template after redirecting.Is it possible actually?

Here is my code:

View.py:

if request.POST:
user = request.POST.get('username')
passw = request.POST.get('password')
#password1 = ''
try:
    userdata = Employee.objects.get(username = user, password = passw)
    user_id = request.session["user_id"] = userdata.id
    employee_details = Employee.objects.get(id=user_id)
    request.session['emp_details'] = employee_details
    return HttpResponseRedirect('/home/')
except Employee.DoesNotExist:
    state = "Username or password incorrect !"
    return render_to_response('login.html',
        {'username' : username1,'state' : state},
        context_instance = RequestContext(request))

template: home.html

<body>
<p>
<ul>
    <li><a href="">{{request.session.emp_details.emp_name}}</a></li>
</ul>
</p>
<p><a href="/logout/"><button>logout</button></a></p>
</body>

Thanks

Make sure that you've added django.core.context_processors.request to your template context processors. Then you can access session variables just as you do in your code.

You may need to add the following line to your view

request.session.modified = True

This depends on whether you have SESSION_SAVE_EVERY_REQUEST = True in your settings. Have a looks at the docs for saving sessions.

Lastly, make sure that you're passing a RequestContext object to the render_to_response function in the view at '/home/'. The RequestContext includes the request object in the template context (making it accessable in the template with {{ request }}).

WARNING

Whilst this should help you get your sessions working - I have to agree with Daniel, you shouldn't be doing user authentication like this. Use django's own authentication.
