Django Interview Questions and Answers

Ques 11. Explain the admin interface in Django.

The admin interface is the interface already available in Django. It helps web developers save their time by eliminating the need to create another admin panel. Django admin is an application that can be easily imported from the package named django.contrib. It comes with user authentication and other features, such as management of various models and CMS, among other things.

The Django admin interface has two default models, Groups and Users, which are included in the admin interface after migrating the project and creating a new superuser.

To login to the default admin space, we need to route the URL to the admin panel, which is http://127.0.0.1:8000/admin/ by default.

Ques 12. How is the code reusability of Django better than other frameworks?

Django offers better reusability of code than other available Python-based web frameworks. It is a collection of various applications, such as login applications, signup, etc. You can copy such applications from one directory to another by making the required changes to the settings.py file. Thus, there is no need to write the entire code for the signup application from scratch. This is why Django helps in the rapid development of web applications.

Django is a batteries-included web framework, which means it comes with some built-in common components such as login, signup, session, and authentication features.

We can easily use those prewritten components code in our web applications by importing them into the script.

Ques 13. What happens when the Django website receives a request?

Whenever a user enters the URL in the browser, the Django server receives the request. The server looks for the URL in its URL-config. If the server finds the match there, it will return the corresponding view function.

Then the request is made to the model of an application to get the data. If there is any data to be passed, pass it to the corresponding template. After, the template renders in the browser. If the process does not work as expected, the user will get a “404” error page.

Ques 14. Can you customize Django’s admin interface? If yes, then how?

Yes, you can customize Django’s admin interface. Django’s admin is another entirely customizable application. It enables you to download another third-party application for a different view. You can create your own admin application to have complete control over it. Also, for customizing the Django admin site, you can change the settings of the admin site object.

Also, you can make the desired changes to your models and then apply them in the Django admin for adding specific applications, such as the search bar. You can customize even a smaller detail of your Django admin interface. Still, it is advisable to create a new admin rather than making so many changes at a lower level.

Ques 15. Why is Django considered a loosely coupled framework?

Django is considered a loosely coupled framework, as it is based on the MVT architecture, a variant of the MVC architecture. The MVT architecture is useful because it entirely separates the server code from the client’s machine.

Models and views are available on a client machine. However, the client only receives the template — the HTML and CSS code — along with the data from the models.

Since these components are different, the front-end and back-end developers can work together on the same project. Making changes to a project by both the teams will not impact each other, thus making Django a loosely coupled framework.
