1fill in blank

easy

Complete the code to set a session variable in Django.

💡 Hint

Common Mistakes

Forgetting to use quotes around the session key name.

Using variable names without quotes which causes errors.

Session keys must be strings, so quotes are needed around 'user_id'.

2fill in blank

medium

Complete the code to set the session expiry time to 5 minutes.

Django

request.session.set_expiry([1])

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

A'5 minutes'

C300

D60

💡 Hint

Common Mistakes

Passing minutes directly instead of seconds.

Using a string instead of an integer.

The set_expiry method expects seconds, so 5 minutes is 300 seconds.

3fill in blank

hard

Fix the error in the code to clear the session data properly.

Django

request.session.[1]()

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

Cdelete

Dremove

💡 Hint

Common Mistakes

Using clear() which only removes data but keeps the session cookie.

Using non-existent methods like delete() or remove().

The flush() method clears the session data and deletes the session cookie.

4fill in blank

hard

Fill both blanks to check if the session has expired and then set a new expiry.

Django

if request.session.get_expiry_age() [1] 0:
    request.session.set_expiry([2])

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

A>

B<

C300

D0

💡 Hint

Common Mistakes

Using wrong comparison operator causing logic errors.

Setting expiry time to zero which means session expires immediately.

Check if expiry age is less than 0 (expired), then set expiry to 300 seconds (5 minutes).

5fill in blank

hard

Fill all three blanks to create a session dictionary comprehension that stores user IDs with expiry times greater than 10 minutes.

Django

active_sessions = {user: request.session.get_expiry_age() [1] 600 for user in users if request.session.get_expiry_age() [2] 600 and request.session.exists([3])}

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

A>

B<

C'session_key'

Duser

💡 Hint

Common Mistakes

Mixing up comparison operators causing wrong filtering.

Using a string literal instead of the user variable for session key.

The comprehension filters users with expiry age greater than 600 seconds (10 minutes) and checks if the session exists for that user key.
