Categories Of Django Interview Questions

Q1) What do you know about the term Django? Briefly explain about some of the technical features that are available in Django.

Ans: Django is referred to as a  high-level web application framework that is based on Python.

The Django framework is one of the best frameworks available in the industry which helps in the rapid development, pragmatic design without affecting or compromising on the features.

Few of the technical features of Django include the following:

  • Admin Interface
  • Security Features
  • Code Reusability
  • ORM
  • CDN Integration

A huge number of third-party applications

Apart from these, There are many features which the Django community has been developing since  a few years and hence it is called “Batteries-Included” framework, as it has lots of features built-in within it. It is  time-consuming and expensive to make if this framework was not developed.

Q2) How do you think that the Django’s code reusability features are different from other frameworks? Justify your answer.

Ans: Django framework is providing its extensive support to offer the feature of  code-reusability more reliably when compared to the other frameworks available in the market. A Django Project is referred to as a collection of different applications that include the login application, signup application.These applications are allowed to be just copied from one directory to another with some tweaks or changes to file and it is not required  to write new signup application from the beginning. This is the reason for which  Django is considered as a rapid development framework and this level of code reusability is not available in any of the  other frameworks.

Q3) Django is called as a MVC based framework, how does this framework implement MVC? Support your answer.

Ans: Django follows an  MTV architecture which is considered to be a variant of MVC architecture. MVC  stands for Model, View, and Controller. There will be different parts of a website so that the development and execution can take place in different machines in order to achieve faster and more responsive websites. Django makes use of the MTV architecture which consists of the three different components and they are all capable of being handled by Django itself.

Models are considered to be as the part in which includes file in a Django application, which is used for defining the data structure of the application being developed.

Views are referred to as the mediators that exist between models and templates, they will be receiving the data from the Model and make it a dictionary and return the same as a response to the request placed to the Template.

The Template is referred to as the component with which the user will be interacting and it is capable of being generated in both statically and dynamically in the Django server.

Q4) Is Django’s Admin Interface considered customizable? If yes, then How?

Ans: Django’s Admin is referred to as one of the applications and very customizable, it also allows you to download a different third-party application and then install it for a totally different view. You are allowed to develop or create your own Admin Application if you would require complete control over the Admin. Although you are allowed to customize the Django Admin site which includes changing the properties of objects. You are also allowed to make some changes in particular models and apply the changes in the Django Admin for specific apps where we can add a search bar for particular applications. The Django Admin Interface is said to be fully customizable to the lowest level, but instead of customizing that much, it is recommended to rather create a new Admin Interface. So those who do not prefer Django Admin Interface can prefer making a new one from scratch than editing the previous one.

Q5) Explain the significance of using the file and what data/ settings it contains?

Ans: Whenever the Django server starts, it starts looking for As the name settings, it is the main settings file of the web application. Everything inside your Django project includes a lot of things like databases, backend engines, middlewares, installed applications, main URL configurations, static file addresses, templating engines, allowed hosts and servers and security key stores in this file as a list or dictionary. Hence, whenever the Django server starts,  it will be executing the file and then move on to the loading of the particular engines and databases so that when a request is given it can serve the same quickly.

Q6) Briefly explain about Django ORM?

Ans: Django ORM is referred to as one of the special feature-rich tools available in Django. ORM stands for Object-Relational Mapper. This ORM provides the ability to a developer to interact with a database in a pythonic way. Django ORM is referred to as the abstraction that exists between models (web application data-structure) and the database where the data is stored.

It makes it possible to perform the operations to retrieve, save, delete and perform other operations over the database without writing any SQL code. It also covers many loopholes and limitations and will be taking all the field attributes and provide you more control over your code in Python rather than any other database language.

Q7) List out the different advantages of using Django?

Ans: Below listed are the advantages of using Django:

  • Django’s stack is known to be loosely coupled with a tight cohesion.
  • Helps in the quick development of websites as and when required within the given deadlines.
  • Follows the DRY or the Don’t Repeat Yourself Principle which means, one concept or a piece of data should live in just one single place
  • It is Consistent at both low as well as high levels
  • Capable of easily dropping into raw SQL whenever required
  • SQL statements are optimized internally and are not executed many times.
  • The Django apps utilize very less code.
  • Behavior are explicitly specified.
  • It is more flexible while using URLs.

Q8) what is the process to connect your Django project to the database?

Ans: Django has come up with a default database which is called SQLite. In order to connect your project to this database, you will need to use the following commands:

python migrate- migrate command is responsible for looking at the INSTALLED_APPS settings and creates database tables accordingly as required.

python makemigrations- it tells Django whenever you have created/ changed your models.

python sqlmigrate name of the app followed by the generated id> -sqlmigrate will take the migration names and return their SQL.

Q9) What are ‘views’?

Ans: The views in Django are capable of serving the purpose of encapsulation. They are capable of encapsulating the logic liable for processing the user’s request and for returning the response back to the user. Views in Django will either return an HttpResponse or will raise an exception such as Http404. HttpResponse includes the objects that consist of the content that is to be delivered or displayed to the user.

Q10) What are ‘Models’?

Ans: Models are referred to as the single and definitive source for information about the data. It includes all the essential fields and behaviors of the data you have stored. Often, each model will be mapped to a single specific database table. In Django, models will serve as the abstraction layer which is used for structuring and manipulating the data. Django models are a subclass of the django.db.models. A Model class and the attributes in the models represent the fields in the database.

Q11) What are ‘templates’?

Ans: A Django’s template layer is used for rendering the information to be presented to the user in a designer-friendly format. Using these templates, you are allowed to generate HTML dynamically. The HTML includes both static as well as dynamic parts of the content. It is possible to have any number of templates based on the requirement of your project. It is also fine if none of them are included. Django has come up with its own template system called the Django template language (DTL). Regardless of the backend, you are also allowed to load and render templates by making use of Django's standard admin.

Q12) Briefly explain what are ‘signals’?

Ans: A Django comes up with a signal dispatcher that helps in allowing the decoupled applications to get notified whenever actions occur or take place elsewhere in the framework. Django has come up with a set of built-in signals that will allow the senders to notify a set of receivers when some action is executed or takes place.

Q13) What are static files?

Ans: The Static files in Django are those files that are responsible for serving the purpose of additional files such as the CSS, images or JavaScript files. These files will be managed by django.contrib.staticfiles. These files will be created within the project app directory by creating a subdirectory named as static.

Q14) What is the process of creating a Django project?

Ans: In order to create a Django project, cd into the directory where you would like to create the project and enter the following command:

django-admin startproject proj

NOTE: Here, proj is the name of the project. You can give any name that you wish to.

Q15) What do you understand by the term ‘sessions’?

Ans: Django provides its full support to sessions. Using the session framework, will help you to easily store and retrieve the arbitrary data that is based on the per-site-visitors. The session framework will basically data on the server-side and takes care of sending and receiving cookies. These cookies include a unique session ID but not do not include the actual data itself unless you explicitly use a cookie-based backend.

Q16) Briefly explain the use of Middlewares in Django.

Ans: By this time, you might have come across numerous Django Interview Questions, where this is one of the most frequently asked questions. Middleware is a framework that is a light and low-level plugin system which is used for altering the Django’s input and output globally. It is also considered as a framework of hooks into the request/ response processing of Django. Each and every component in middleware has some particular task to be performed. For example, AuthenticationMiddleware is used for associating with the users with their requests using sessions. Django is flexible to provide many other middlewares such as cache middleware which will enable site-wide cache, common middleware that allows to performs many tasks such as forbidding access to user agents, URL rewriting, etc, GZip middleware that is used for compressing the content for browsers, etc.

Q17) Is Django better than Flask?

Ans: Django is referred to as a framework that will allow you to build large projects. On the other hand, Flask is used for building smaller websites but flask is much easier to learn and use when compared to Django. Django is a full-fledged framework and does not require any third-party packages. The Flask is more of a lightweight framework that will allow you to install third-party tools as and how you like. Hence the ultimate answer is dependent on the user’s requirements and in case the requirement is very heavy, the answer will definitely be Django.

Q18) Give a brief idea about the different inheritance styles in Django?

Ans: There are three different inheritance styles in Django:

1) Abstract base classes: The abstract base class style is used when you only require a parent's class to hold the information that you would not like to type out for each child model.

2) Multi-table Inheritance: The multi-table inheritance style is used if you are subclassing an existing model and will need each model to have its own database table.

3) Proxy models: The proxy model style is used, if you would like to modify the Python level behavior of the model, without changing the model's fields.

Q19) What are the two important parameters in signals?

Ans: There are two important parameters in signals. They  are:

Receiver: It specifies the callback function which is connected to the signal.

Sender: It specifies a particular sender from where a signal is being received.
