What does this Django view return?

Consider this Django view function using the redirect function. What will the user see after accessing this view?

Django

from django.shortcuts import redirect

def my_view(request):
    return redirect('home')

A The view raises a NameError because 'home' is not defined.

B The user sees a page with the text 'home'.

C The user is redirected to the URL mapped to the name 'home'.

D The user sees a 404 error page.

💡 Hint

Think about what the redirect function does with a string argument.

The redirect function takes a URL name and sends the user to that URL. It does not render text or raise an error if the URL name exists.

Which option correctly uses the redirect function to send to a URL path?

You want to redirect the user to the URL path '/dashboard/'. Which code snippet correctly does this?

A return redirect('dashboard')

B return redirect(path='/dashboard/')

C return redirect(url='/dashboard/')

D return redirect('/dashboard/')

💡 Hint

The redirect function can take a URL path as a string directly.

Passing '/dashboard/' as a string to redirect sends the user to that exact URL path. The other options either misuse parameters or treat the string as a URL name.

Why does this redirect cause an error?

This Django view tries to redirect using a variable but causes an error. Why?

def my_view(request):
    url_name = home
    return redirect(url_name)

Django

def my_view(request):
    url_name = home
    return redirect(url_name)

A NameError because 'home' is not defined as a variable or string.

B TypeError because redirect expects a string but got a variable.

C No error, it redirects correctly to 'home'.

D ValueError because 'home' is not a valid URL.

💡 Hint

Look at how the variable url_name is assigned.

The code assigns url_name = home without quotes, so Python looks for a variable named home which is not defined, causing a NameError.

What is the HTTP status code of this redirect response?

Given this Django view, what HTTP status code will the redirect response have?

from django.shortcuts import redirect

def my_view(request):
    return redirect('login')

Django

from django.shortcuts import redirect

def my_view(request):
    return redirect('login')

A 302 Found (temporary redirect)

B 301 Moved Permanently

C 404 Not Found

D 200 OK

💡 Hint

By default, redirect sends a temporary redirect status.

Django's redirect function returns an HttpResponseRedirect with status code 302 by default, indicating a temporary redirect.

Which redirect usage correctly passes URL parameters?

You want to redirect to a URL named 'profile' that requires a username parameter. Which option correctly passes the parameter using Django's redirect function?

A return redirect('profile', {'username': 'alice'})

B return redirect('profile', username='alice')

C return redirect('profile?username=alice')

D return redirect('profile/username/alice')

💡 Hint

Use keyword arguments to pass URL parameters to redirect.

The redirect function accepts the URL name and keyword arguments for URL parameters. Option B correctly uses this pattern.
