Introduction to Django

Hello everyone, from today we’re going to start a new tutorial series on Django framework. In this tutorial we will cover basic introduction of Django. Before start to learn, lets have a look on some most frequently asked questions about Django. These questions will help you to understand that what actually Django is.

  1. What is Django?
  2. Why use Django?
  3. How does Django work?
  4. Is Django stable?
  5. What are the requirements to learn Django?

So let’s answer these questions one by one.

Introduction to Django

What is Django?

Django is open-source and free web framework. It is written in Python language. It was created about 13 years ago (21 july 2005) and the latest and stable release Django 2.1 is out this year (1 august 2018) with a whole new set of features and capabilities. It is maintained by the Django Software Foundation, an independent organization established as a 501 non-profit. Django is a framework for web developers, it provides amazing infrastructure required for database-driven websites that have user authentication, content administration, file uploads, and much more.

We doesn’t have to create all these features from sratch, we can use Django framework and utilize these components that are already built-in there, so we can save a lot of time by using these inbuilt components. If you love to working  with python, especially for web application or web design, then you should learn the Django framework.

Why use Django?

We already have seen that how it saves a lot of time for us. There are some another reasons to use Django framework.

  1. Components: It is a light weight and stand alone web server where we can develop and test our project, a template system that uses the concept of inheritance from OOP, supports caching the data into memory, supports middleware framework (a light and low level plugin which is a system for altering input and output of django), consists of an object-relational mapper (ORM) that mediates between python classes and a relational database and many other components are there.
  2. Bundled Applications: Django also includes a number of applications in its contrib package like – dynamic admin interface, an extensible authentication system that follows EAP (extensible authentication protocol), tools for creating Atom (web feeds) and RSS, tools for producing google sitemaps, a site’s framework which allows us to install django only once and run more than one websites, having different contents, inbuilt tool to reduce cross-site scripting, cross-site request forgery, SQL injection, cracking password and mitigate other web attacks.
  3. Extensibility: Django allows us plug the third party code into a regular project, so that it can be re-used. There are around 2500 packages to extend the framework’s original behavior.

There are many other reasons to use Django framework, which will you know while learning it.

How does Django work?

It can be broken into several components like Models.py, URL.py, Views.py files. Each file have their own specification like Models.py defines our data model by extending your single code line into full database tables and add a pre-built administration section to manage content, while on other hand Views.py is the main part of Django. Actual processing happens in view. We’ll discuss it later in detail.

Is Django stable?

Of course, Django is stable. Most of the companies are using it. Some of them are:

  • Bitbucket
  • Instagram
  • Pinterest
  • Mahalo
  • The washington post’s webstite

What are the requirements to learn Django?

You should be familiar with basic syntax of Python, functions, importing external modules, conditional operator, loops, Regular Expression, data structure like tuple, set and dictionary, and a computer to work with.

That’s all for this article, if you have any problem or question related to introduction to Django then comment below, we’ll reply as soon as possible.

dotnet sdk list and dotnet sdk latest

Can someone make .NET Core better with a simple global command? Fanie Reynders did and he did it in a simple and elegant way. I'm envious, in fact, because I spec'ed this exact thing out in a meeting a few months ago but I could have just done it like he did and I would have used fewer keystrokes! Last year when .NET Core was just getting started, there was a "DNVM" helper command that you could use to simplify dealing with multiple versions of the .NET SDK on one machine. Later, rather than 'switching global SDK versions,' switching was simplified to be handled on a folder by folder basis. That meant that if you had a project in a folder with no global.json that pinned the SDK version, your project would use the latest installed version. If you liked, you could create a global.json file and pin your project's folder to a specific version. Great, but I would constantly have to google to remember the format for the global.json file, and I'd constan...

15 Web Design Trends to Watch in 2018

The modern world is full of extraordinary things that influence our imagination and mood. Our soul needs a perfect atmosphere and impressive spots. To apply such things in practice, we have submitted the list of the web trends that deserve your attention. Robert frost design analysis will meet all your wishes and expectations. Image Source Web Design Trends to Watch in 2018 1. More Organic Shapes Until this year, web design, as well as mobile design, were based on the right-angled and sharp-edged shapes. However, it seems that this year will bring some significant changes in the field of web design. The recent trends will offer the absolute rounded corners. In addition, the web design of 2018 will make the real things look like the cartoonish ones. 2.   Bold Minimalism Although some of you may think that this web design trend will not attract the Internet users. Indeed, the notion of minimalism is often associated with boredom and dullness. However, in this case, bold ...

Data Encryption Standard (DES) Algorithm

Data Encryption Standard is a symmetric-key algorithm for the encrypting the data. It comes under block cipher algorithm which follows Feistel structure. Here is the block diagram of Data Encryption Standard. Fig1: DES Algorithm Block Diagram [Image Source: Cryptography and Network Security Principles and Practices 4 th Ed by William Stallings] Explanation for above diagram: Each character of plain text converted into binary format. Every time we take 64 bits from that and give as input to DES algorithm, then it processed through 16 rounds and then converted to cipher text. Initial Permutation: 64 bit plain text goes under initial permutation and then given to round 1. Since initial permutation step receiving 64 bits, it contains an 1×64 matrix which contains numbers from 1 to 64 but in shuffled order. After that, we arrange our original 64 bit text in the order mentioned in that matrix. [You can see the matrix in below code] After initial permutation, 64 bit text passed throug...
