Django tip: How to set and get sessions?

/ #Django

Using sessions with Django is easy and it's something that you should know how to do as a developer.

Set up

Sessions comes built in with the standard Django setup. But it's always nice to just double check that "'django.contrib.sessions'," is in your list of INSTALLED_APPS in your file.

Setting sessions

In this little example, I will show you how to set a session.

def index(request):
    # String
    request.session['username'] = 'codewithstein'

    # Integers
    request.session['user_id'] =

    # Booleans
    request.session['is_authenticated'] = True

    return render(request, 'index.html')

Great. Now we have a few session variables with strings, integers and boolean values.

Getting sessions

Getting sessions is also very easy.

def myaccount(request):
    # Check if "is_authenticated" is true. Default it to "False"
    if request.session.get('is_authenticated', False):
        print('You are authenticated')

    # Set username in a variable

    username = request.session.get('username', '')

    if username:
        print("Your username is %s" % username)
    return render(request, 'myaccount.html')

Deleting sessions

Now we know how to set and get sessions. But sometimes we want to delete them as well.

def logout(request):
        del request.session['is_authenticated']
    except KeyError:
        print("The key didn't exist")
    return redirect('index')

So now you know how to use sessions :-D

So, I would like you to help me please.
