Using 'signed_cookies' backend instead of 'db' for database sessions.

💡 Hint

Common Mistakes

Using dot notation instead of brackets for session keys.

Not quoting the session key string.

To store a value in session, use request.session['key'] = 'value'. The key must be a string inside brackets.

5fill in blank

hard

Fill all three blanks to retrieve a session value with a default in a Django view.

Django

def my_view(request):
    color = request.session.get([1], [2])
    return HttpResponse(f'Favorite color is [3]')

Drag options to blanks, or click blank then click option'

A'favorite_color'

B'unknown'

Ccolor

D'color'

💡 Hint

Common Mistakes

Not using quotes around the session key.

Using the string 'color' instead of the variable color in the response.

Use request.session.get('key', 'default') to safely get a session value. Then use the variable color in the response.
