In this blog, I'll be going over some of the most important interview questions asked during a django developer interview. These include some of the classics as well as my personal experience with the interviews and questions that I recall being asked. let's get right into it...
Since Django is a Python framework so a lot of the questions would be related to Python as well. I will be writing another blogpost for just the Python interview question if you want just those but for now, here will be a mix of python and django questions and answers.
Django is a web framework based on python, it is free and open source. The main purpose of using django is to get some website or web app developed quickly and securely. Although its main purpose is to develop websites but it is vastly used as a REST API back end by a lot of companies who write their mobile app's backend on Django. there are packages like the Django Rest Framework available to help facilitate this feature. Django comes with a lot of the cool features which makes it easier, faster to develop on, and secure.
The main leverage Django has over other frameworks like laravel is that it is based on python and all of the python libraries can be used to get something done which is a huge upside because they are well maintained and there is almost no complexity in using them with django.
NO, It is certainly not a frontend framework however it supports other frontend frameworks to be integrated in it. By default django uses basic HTML/CSS for developing frontend using JINJA template engine to show dynamic data. You can integrate ReactJS, VueJS, Angular possibly others frameworks as well into your django app.
It supports all of the major databases which include:
But the goto and most used databases with django are PostgreSQL and MySQL.
It even supports connecting to more than 1 Databases in a single project.
The flow of Django is not the usual MVC but slightly different naming and what I'll call here MVT (Model View Template). The working can be seen in the image flow here
briefly explaining user hits the URL which is resolved by django and extact 2 main things from the URL i.e. View and parameters passed then that resolved View is run and parameters are passed along which contains further logic and that logic migh require django to get something from the database which are defined as models here the data is retrieved from the models and then passed to the template which then completes the flow. so the actual flow can be formated as URL -> View -> Model (optional) -> template.
It has the following features that increase the developer's productivity
Views in django contain all of the logic and are connected to both templates and models. they get the data from models and pass them over to the template.
There are 2 types of views in Django
