What is Django?

Django is an MVT web framework used to build web applications. It defines itself as a “batteries included” web framework, with robustness and simplicity to help web developers write clean, efficient and powerful code.

It is among the most famous web frameworks out there in the world and it’s one of the most used frameworks as well. It’s used by Instagram, Youtube, Google and even NASA for their website.

So let’s break it down even further to learn more about it.

The Structure

Django follows an MVT architecture which stands for Model-View-Template.

MVT is a Django variation of the famous MVC structure, that’s why you’ll feel it’s quite analogous to how other frameworks work.

When the Django server receives a request, the URL router maps the request to the appropriate view. The view then fetches the data through the models, fill the template and send it back to the user.


Django’s Templates

Django has a powerful template engine and its own markup language with many tools.

Templates are files with HTML code that’s used to render data. The contents of these files can be static or dynamic.

Since there’s no business logic in a template, it’s there only to present data.


What is Django used for?

People with little understanding of Django think it’s a mere content management system. In reality, it’s a software tool designed to build and run web applications.

The origin of the framework’s name is key to understanding its multifaceted nature. The Django framework owes its name to jazz guitarist Django Reinhardt, who was able to play dazzling runs on his guitar even though two of his fingers were paralyzed after an accident. In the same way, the Django framework can take on numerous tasks.

Django can be used for creating:

  • Client relationship management (CRM) systems;
  • Content management systems (CMS) for internal and commercial use;
  • Communication platforms;
  • Booking engines;
  • Document administration platforms;

Among other things, Django is great for:

  • Algorithm-based generators;
  • Emailing solutions;
  • Verification systems;
  • Filtering systems with dynamically changing rules and advanced parameters;
  • Data analysis solutions and complicated calculations;
  • Machine learning;

There are thousands of websites across the globe with Django at their core.

Advantages of Django

Here are the most important reasons why to use Django for custom websites. We think these reasons apply equally well to the startup projects and for business gurus.

1. Django has Batteries included

Django prides itself as a batteries-included framework. What that means is that it comes with a lot of stuff out of the box, that you may or may not use depending on your application. Instead of having to write your own code (the power), you just need to import the packages that you want to use.

It’s a part of the convention over configuration paradigm that Django is part of, and it allows you to make use of the solutions implemented by world-class professionals. Django batteries span a wide range of topics that include:

  • Authentication with auth package
  • Admin interfacing with admin package
  • Session management with Sessions package
  • Managing temporary or session-based messages with Messages package
  • Generating Google sitemap XML with Sitemaps package
  • Postgres special features with Postgres Package
  • Hooking into “types” of content with content types framework

2. It’s basically Python Language

Django is written in Python. The Python language is truly simple to learn and seems as it was created for newbies. Let’s see one example, just the classic code that newbies write when learning a new language:

In Python:

print "Hello World!"

In Java:

public class Main {

    public static void main(String[] args) {

       System.out.println("Hello World!");

    }

}

As you probably notice, Python’s allows managing more in fewer lines comparing to Java. Simplicity is the main key.


3. Community Support

Django’s community is one of the best things about it, they are helpful and actively working on making the framework more beginner-friendly and stabilizing the framework while adding new features.

Django’s documentation is quite thorough and is useful as a standalone tutorial, it will help you wrap your head around various features so you can use it as a primary source of information.


4. Django is Immensely Scalable

One of the nicest advantages of Django is that it can handle traffic and mobile app API usage of more than 400 million+ users helping maximize scalability and minimize web hosting costs. And when talking about hosting, we need to mention that the number of hosts is high and hosting price is relatively cheap and even free.


5. Rich ecosystem

Read Django like a system, developers say. What they mean is that there are many third-party applications that come with Django.

These applications can be integrated depending on project requirements. To imagine this better, think of Legos. There are many different Lego blocks. In app development, an authorization “block” or email sending “block” is present in almost every project.

Django consists of many applications — such as for authorization and sending emails — that can easily be plugged into a system.


6. Built-in Admin Panel

Admin panels are designed to help you manage your application. A Django admin panel is generated automatically from Python code, whereas creating an admin panel manually would take a lot of time and be absolutely pointless.

There’s a lot of room for customization in the Django admin panel thanks to third-party applications. Additionally, Django allows you to modify the interface with third-party wrappers and add dashboards unique to your needs.

Disadvantages of Django

Along with the advantages, come the disadvantages. There are some disadvantages of Django mentioned below :

1. URL Specification

You can create simple and easy-to-read URLs. However, Django uses regex to specify its URL routing patterns and that makes the code larger and creates complicated syntaxes. This is an example straight from the documentation:

r'^articles/(?P<year>[0-9]{4})/$'

r'^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/$'

r'^articles/(?P<year>[0-9]{4})/(?P<month>[0-9]{2})/(?P<day>[0-9]{2})/$'


2. Monolithic

Some internal Django modules, such as ORM and forms, are hard to replace; it will require a lot of effort from your developers to change the internal structure.


3. Far too slow while maintaining Backward compatibility

The framework has dedicated itself to backwards compatibility. What does that mean? It tends to get bigger and heavier over time.

Speed is a valid issue even in Python, but Django has explicitly chosen to designate other stuff. Django worries more about dev productivity and backwards compatibility than its speed.


4. Not for smaller projects

All the functionality of Django comes with lots of code. It takes server’s processing and time, which poses some issues for low-end websites which can run on even very little bandwidth.

For example, if you need to design a simple chat, Django can be too big of a framework and you can instead go with Flask, a microservice framework.


5. Steep learning curve

One of the primary disadvantages is that the Django web framework has a steep learning curve.

Developers making a switch from other languages to Python development with Django often find it harder to learn. The framework has different syntax due to Python, and developers don’t get the hang of it quickly.

The Future Of Django !

Strong community, constant updates, established user base and positive trends. I’d say the future is bright, although there are some upcoming competitors like Flask, that are gaining popularity, so it might be a good idea to keep an eye on them.

In reality, Flask and the other similar lightweight web frameworks are not really direct competitors of Django. They are great for quickly spinning up a microservice with a simple API, but they do not have all the built-in extra functionality that Django offers. In that regard Django is really one-of-a-kind among the Python-based frameworks.

When Not To Use Django?

There are some cases, when Django can really feel like an overkill. For example, if you’re building a small, stateless microservice, then I see absolutely no point in using Django. If you need only rest API, no UI, no admin area, no database – then Django would provide no benefit at all.
