Django

I'm Ankitha working for Luxoft India, as a junior software engineer. I'm a python developer and it is important to know Djnago - third party library in Python. So, here is an article about Oops.

Introduction:

Django is a high-level web framework that is used for rapid development of web applications. It is a free and open-source framework that follows the Model-View-Controller (MVC) architectural pattern.

Django's ORM (Object-Relational Mapping) is one of its most powerful tools, allowing developers to map their database schema to Python classes, and interact with the database using Python code.

Another advantage of Django is its built-in admin interface. This allows developers to easily create an admin interface for their application, without having to write any code. The admin interface provides a user-friendly interface for managing data and content within the application. It can be customized to fit the needs of the application, and can even be extended to include custom functionality.

Django is also known for its security features. It comes with built-in protection against many common web application vulnerabilities, such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Django's built-in authentication system is also highly secure, with features like password hashing, session management, and user permissions.

One of the reasons for Django's popularity is its large and active community.The Django community is also very helpful and supportive, with many developers willing to answer questions and provide assistance.

In addition to its built-in features, Django also has a vast ecosystem of third-party packages and libraries. These packages can be easily installed using the pip package manager, and can add additional functionality to the application. For example, there are packages for integrating Django with popular front-end frameworks like React and Angular, as well as packages for handling payments, sending emails, and more.

In conclusion, Django is a powerful and versatile web framework that is ideal for building complex web applications. Its built-in tools and features, along with its strong security and active community, make it a top choice for developers. Whether you're a beginner or an experienced developer, Django has something to offer.

Some of the Django features include:

Object-Relational Mapping (ORM):

Django provides an ORM that maps database tables to Python classes, allowing developers to interact with the database using Python code.

Admin Interface:

Django includes a built-in admin interface that allows developers to manage database records and perform CRUD (Create, Read, Update, Delete) operations.

URL Routing:

Django has a powerful URL routing system that makes it easy to define URLs for views and map them to specific functions or methods.

Template Engine:

Django has a powerful template engine that allows developers to create reusable templates and generate HTML dynamically based on data passed to them.

Security:

Django includes built-in security features such as protection against CSRF (Cross-Site Request Forgery) attacks, XSS (Cross-Site Scripting) attacks, and SQL injection attacks.

Scalability:

Django is designed to be scalable and can handle high traffic websites with ease.

Built-in Middleware:

Django includes built-in middleware that allows developers to add functionality to the request/response cycle, such as authentication, caching, and compression.

Internationalization:

Django includes built-in support for internationalization and localization, allowing developers to easily create applications that support multiple languages.

Testing:

Django provides a built-in testing framework that allows developers to write and run tests to ensure their code is working as expected.

Third-Party Libraries:

Django has a large and active community that has developed a wide range of third-party libraries to extend its functionality, such as Django REST framework for building RESTful APIs and Django Channels for building real-time applications.

Example of django:

from django.shortcuts import render
import openpyxl

def create(request):
    if request.method == "GET":
        return render(request,'fileupload.html')
    else:
        exl_data=explore(request)
        return render(request, 'fileupload.html', {"excel_data":exl_data})

def explore(request):
        excel_file = request.FILES["excel_file"]
        wb = openpyxl.load_workbook(excel_file)
        ws = wb.active
        excel_data = []
        for row in ws.iter_rows():
            row_data = []
            for cell in row:
                row_data.append(str(cell.value))
            print(row_data)
            excel_data.append(row_data)

        print(excel_data)
        return excel_data

Conclusion:

In conclusion, Django is a widely-used Python web framework that provides developers with a comprehensive set of tools for building web applications. Its ease of use, versatility, and scalability make it a popular choice for building everything from simple websites to complex, data-driven applications. With its powerful ORM system and built-in admin interface, Django streamlines the development process and allows developers to focus on creating high-quality, feature-rich web applications.
