DataFlair has a complete series of Django quizzes. Make sure to bookmark them:

Let’s start the quiz.

Q.1 Suppose you want to count the number of books in Django.
books = Book.objects.all()
Which implementation would be fastest?

Correct! Wrong!

The database level implementation will always be faster than the Python implementation. Python implementation is faster than the template’s implementation. To improve performance, mostly lower-level implementations are preferred.

Q.2 From the previous question, suppose we want to implement the Query in the template. Choose one option which provides an optimal solution.

Correct! Wrong!

The second implementation is the fastest. If you see, we are actually performing the books.count() in the template. It is even more optimal than the one with a database solution in the previous question.

Q.3 What are some of the ways by which we can improve the site’s performance?

Please select 5 correct answers

Correct! Wrong!

The techniques described here are all recommended by Django’s Documentation. The latter is not always effective. Caching the whole site won’t be of any use for large websites. It will only consume more memory. Using the template language for processing is not a good idea if the same can be achieved in view. The template language adds the templates header time which is extra in every sense.

Q.4 Which of these variables are the settings for django.contib.staticfiles app?

Please select 4 correct answers

Correct! Wrong!

Often Django developers take media settings as the staticfiles app. The media settings are for a different Django app and middleware. The STATICFILES_DIRS and STATICFILES_FINDERS are used when the project contains multiple static files directory. The finders also become important when the website becomes large and has various static assets that change frequently.

Q.5 Which of these commands is not a management command of staticfiles?

Correct! Wrong!

Q.6 What data types and objects are not accepted as an argument by Paginator class?

Correct! Wrong!

Dictionaries in Python don’t have a count(). The obvious answer could have been the dictionary but the dictionary does have the len method. Although using a dictionary in Paginator is not very fruitful as the methods are not made to iterate over a dictionary.

Q.7 Suppose I have a Python class like this. Now, if we pass the obj in a context variable and add the template like this. {{ obj.topic }} Which value will the template engine return?

python class - Django MCQ
Correct! Wrong!

The template system lookup works like this. Class attributes are searched before any method lookups. Therefore, the topic is returned rather than the method execution.

Q.8 What are some valid forloop attributes of Django Template System?

Please select 3 correct answers

Correct! Wrong!

Q.9 Which of these is not a valid method or approach to perform URL resolution?

Correct! Wrong!

All three methods are valid and provide the absolute URL of the resources.

Q.10 Which of the following Password Validators are not provided by default in Django?

Correct! Wrong!

The default password validators check for the minimum length of the password. They check whether the password is not completely numerical. Also, The CommonPasswordValidator will check whether the password matches with common passwords. The common passwords are a list of 20,000 passwords. The last one is not a default Password Validator.

Q.11 Which of these are not built-in Validators in Django?

Correct! Wrong!

Q.12 Which of these is not a step in Form Validation?

Correct! Wrong!

Form validation is a complex process and comprises of various steps. Although, there is no tampering with data so there is no meaning of a clear method. The other methods are there to convert the data into Python data type. That data is then passed through custom and built-in validators. At last, we get cleaned data.

Q.13 When we execute form.clean() on a form object and suppose at any point validation error is raised by a validator. What happens after the Validation Error occurs?

Correct! Wrong!

Q.14 Suppose I have a directory structure as shown. We want to extend the temp2.html and dataflair.html in temp3.html. Select all the options with the correct extend statement. The extend statement is written in temp3.html.
