What does this Django TemplateView render?

Given the following Django TemplateView, what will be the rendered output when accessing the URL mapped to this view?

Django

from django.views.generic import TemplateView

class WelcomeView(TemplateView):
    template_name = "welcome.html"

# Assume welcome.html contains: <h1>Welcome to our site!</h1>

A <h1>Hello, user!</h1>

B TemplateDoesNotExist error

C <h1>Welcome to our site!</h1>

D Empty page with no content

💡 Hint

Check what the template_name attribute points to and what the template contains.

The TemplateView renders the template specified by template_name. Since welcome.html contains the heading, that is what will be rendered.

What context data is available in this TemplateView?

Consider this Django TemplateView: from django.views.generic import TemplateView class InfoView(TemplateView): template_name = "info.html" def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['page_title'] = 'Information Page' return context What is the value of 'page_title' in the template context when rendering info.html?

A None

B Information Page

C page_title

D Raises AttributeError

💡 Hint

Look at how get_context_data adds 'page_title' to the context dictionary.

The get_context_data method adds 'page_title' with value 'Information Page' to the context, so the template can access it.

Which option correctly overrides TemplateView to pass extra context?

You want to add extra context data 'user_role' with value 'admin' to a TemplateView. Which code snippet correctly does this?

A

class MyView(TemplateView):
    template_name = 'dashboard.html'
    extra_context = {'user_role': 'admin'}

B

class MyView(TemplateView):
    template_name = 'dashboard.html'
    def get_context_data(self):
        return {'user_role': 'admin'}

C

class MyView(TemplateView):
    template_name = 'dashboard.html'
    def get_context(self):
        return {'user_role': 'admin'}

D

class MyView(TemplateView):
    template_name = 'dashboard.html'
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['user_role'] = 'admin'
        return context

💡 Hint

Remember to call super() when overriding get_context_data to preserve existing context.

Option D correctly overrides get_context_data, calls super(), adds 'user_role', and returns the updated context.

Why does this TemplateView raise TemplateDoesNotExist?

Given this view: from django.views.generic import TemplateView class AboutView(TemplateView): template_name = 'about_us.html' But when accessing the URL, Django raises TemplateDoesNotExist: about_us.html. What is the most likely cause?

A The template file about_us.html is missing from the templates directory.

B The template_name attribute is misspelled and should be templateName.

C TemplateView requires a render() method to be defined.

D The URL pattern is not mapped to AboutView.

💡 Hint

Check if the template file exists in the correct folder.

TemplateDoesNotExist means Django cannot find the template file. The most common cause is the file missing or in the wrong folder.

How does TemplateView handle HTTP GET requests internally?

Which statement best describes how Django's TemplateView processes an HTTP GET request?

A TemplateView calls get_context_data(), renders the template with context, and returns an HttpResponse.

B TemplateView uses a form to process GET data before rendering.

C TemplateView requires a manually defined get() method to handle GET requests.

D TemplateView directly returns the template file content without context processing.

💡 Hint

Think about the flow of data from request to response in TemplateView.

TemplateView's get() method calls get_context_data(), renders the template with that context, and returns the response automatically.
