What does this Django function-based view return?

Consider this Django view function. What will the user see when visiting the URL linked to this view?

Django

from django.http import HttpResponse

def greet(request):
    return HttpResponse('Hello, friend!')

A A blank page with no content

B A JSON response with the message 'Hello, friend!'

C The text 'Hello, friend!' displayed in the browser

D A server error because the view is missing a template

💡 Hint

HttpResponse sends plain text back to the browser.

The view returns an HttpResponse with the string 'Hello, friend!'. This text appears in the browser as plain content.

📝 Syntax

intermediate

Identify the syntax error in this Django view

Which option correctly fixes the syntax error in this function-based view?

Django

from django.http import HttpResponse

def welcome(request)
    return HttpResponse('Welcome!')

A Indent the return statement one level less

B Add a colon after the function definition: def welcome(request):

C Remove the parentheses from the function definition

D Change HttpResponse to JsonResponse

💡 Hint

Function definitions in Python always end with a colon.

The function definition is missing a colon at the end of the line. Adding ':' fixes the syntax error.

❓ state_output

What is the output of this view when accessed with a GET request?

Analyze this Django view. What will the user see when they visit the URL with a GET request?

Django

from django.http import HttpResponse

def check_method(request):
    if request.method == 'POST':
        return HttpResponse('Posted!')
    else:
        return HttpResponse('Not a POST request')

A 'Posted!'

B A 404 Not Found error

C A server error due to missing POST handling

D 'Not a POST request'

💡 Hint

The view checks the HTTP method and returns different responses.

Since the request is GET, the else branch runs, returning 'Not a POST request'.

🔧 Debug

advanced

Why does this Django view cause a runtime error?

This view raises an error when accessed. What is the cause?

Django

from django.http import HttpResponse

def broken_view(request):
    return HttpResponse('All good!', status=200)

A HttpResponse does not accept positional arguments after keyword arguments

B HttpResponse requires a template to render

C The status code 200 is invalid

D The view is missing a return statement

💡 Hint

Check the order of arguments passed to HttpResponse.

HttpResponse expects the content as the first argument. Passing status=200 before content causes a TypeError.
