Practice

1. What is the main purpose of Django's logout view?

easy

A. To display the user's dashboard

B. To create a new user account

C. To update user profile information

D. To end the user's session and log them out securely

Solution

1. Step 1: Understand the logout function role

   The logout view is designed to end the current user's session, removing their authentication.

2. Step 2: Identify the purpose of logout

   Logging out ensures the user is no longer authenticated, protecting their account.

3. Final Answer:

   To end the user's session and log them out securely -> Option D

4. Quick Check:

   Logout view ends session = A [OK]

Hint: Logout always ends user session securely [OK]

Common Mistakes:

• Confusing logout with login or registration
• Thinking logout updates user data
• Assuming logout shows user content

2. Which of the following is the correct way to call Django's logout function inside a view?

easy

A. logout(request)

B. logout(user)

C. logout()

D. logout(request, user)

Solution

1. Step 1: Check logout function signature

   Django's logout function requires the current request object to identify the session.

2. Step 2: Match correct usage

   Calling logout with only the request parameter is correct: logout(request).

3. Final Answer:

   logout(request) -> Option A

4. Quick Check:

   logout needs request object = D [OK]

Hint: Logout always needs the request object as argument [OK]

Common Mistakes:

• Passing user instead of request
• Calling logout without arguments
• Passing multiple arguments incorrectly

3. What will happen when this Django view code runs?

from django.contrib.auth import logout
from django.shortcuts import redirect

def logout_user(request):
    logout(request)
    return redirect('home')

medium

A. Syntax error because logout is not imported

B. User session ends and browser redirects to 'home' URL

C. User session remains active and page reloads

D. Redirect fails because 'home' URL is missing

Solution

1. Step 1: Analyze logout call

   The logout(request) call ends the user's session by clearing authentication data.

2. Step 2: Analyze redirect call

   The redirect('home') sends the user to the URL named 'home' after logout.

3. Final Answer:

   User session ends and browser redirects to 'home' URL -> Option B

4. Quick Check:

   logout + redirect = C [OK]

Hint: Logout then redirect to send user away [OK]

Common Mistakes:

• Assuming logout does not end session
• Confusing redirect with render
• Missing import causing errors

4. Identify the error in this logout view code:

from django.contrib.auth import logout
from django.shortcuts import redirect

def logout_user(request):
    logout()
    return redirect('home')

medium

A. logout() missing required request argument

B. redirect('home') is incorrect syntax

C. logout should be imported from django.shortcuts

D. Function name must be 'logout_view'

Solution

1. Step 1: Check logout function call

   The logout function requires the request object as an argument, but here it is called without any arguments.

2. Step 2: Verify other parts

   Redirect syntax is correct, import is from django.contrib.auth, and function name can be arbitrary.

3. Final Answer:

   logout() missing required request argument -> Option A

4. Quick Check:

   logout needs request argument = A [OK]

Hint: Always pass request to logout() [OK]

Common Mistakes:

• Calling logout without request
• Wrong import source for logout
• Assuming function name is fixed

5. You want to create a logout view that logs out the user and then shows a goodbye message on a page instead of redirecting. Which is the best way to do this?

hard

A. Call logout(request) then use redirect('goodbye')

B. Use Django's built-in LogoutView with next_page='goodbye'

C. Call logout(request) then use render(request, 'goodbye.html')

D. Call logout() then use render(request, 'goodbye.html')

Solution

1. Step 1: Understand logout and response options

   Calling logout(request) ends the session. To show a message, you render a template instead of redirecting.

2. Step 2: Choose correct method to show message

   Using render(request, 'goodbye.html') displays the goodbye page immediately after logout.

3. Final Answer:

   Call logout(request) then use render(request, 'goodbye.html') -> Option C

4. Quick Check:

   Logout + render page = B [OK]

Hint: Logout then render template to show message [OK]

Common Mistakes:

• Using logout() without request
• Redirecting instead of rendering for message
• Misusing LogoutView without template
