Django Template Language Simplifies Web Development with Python

How Django Works: Understanding the MVT Pattern (Model-View-Template) If you’re learning Python Django, understanding the MVT architecture is a game-changer. This poster visually explains how Django handles a request from start to finish 👇 🔹 Model (Data Layer) Handles database structure and data logic using Django ORM. 🔹 View (Business Logic) Processes user requests, interacts with models, and prepares the response. 🔹 Template (Presentation Layer) Renders dynamic HTML and displays data to the user. 🧠 Flow in simple terms: User Request ➝ View ➝ Model ➝ View ➝ Template ➝ Response Django keeps things clean, scalable, and secure by separating responsibilities clearly. That’s why it’s trusted for building production-ready web applications. 📌 Perfect for: --> Beginners learning Django --> Students preparing for interviews --> Developers revising architecture concepts 💬 Let me know in the comments: Do you prefer MVT (Django) or MVC (other frameworks)? #Django #Python #WebDevelopment #BackendDevelopment #SoftwareEngineering #MVT #Programming #LearnDjango #FullStack #Developer

WHY DJANGO REST_FRAMEWORK? DAY 9: ‎ ‎THE BROWSABLE API (YOUR SECRET WEAPON) ‎ ‎One of the biggest differences between Django and DRF is how you see your work. ‎ ‎In standard Django, if you want to see if your logic works, you’re either looking at the Admin Panel or building a quick HTML template. Although, it gives a little more room for customization, it is still a bit of a detour. ‎ ‎Enter the DRF Browsable API. ‎ ‎heThe moment you create a view in DRF and navigate to the URL in your browser, you aren't just looking at raw JSON text. DRF renders a clean, interactive web page that allows you to: ‎ ‎1. GET data and see it beautifully formatted. ‎ ‎2. POST new data using a built-in form. ‎ ‎3. PUT/DELETE resources with the click of a button. ‎ ‎It is essentially a live Sandbox for your backend. You can test your entire backend logic directly in the browser. ‎ ‎For me, this was actually pretty fascinating, just seeing my Python logic turn into a functional interface  that I could interact with, without writing a single line of CSS or HTML. It makes debugging feel less like a chore and more like a playground. ‎ ‎Do you prefer testing your logic in the terminal (Shell) or are you like me and you need a visual interface to feel like it’s real? ‎ ‎#APIs #webdevelopment #learninginpublic #learninpublic #whydjangorestframework #django #djangrestframework #python #webdev #backenddevelopment

WHY DJANGO REST_FRAMEWORK? DAY 5: ‎ WHAT IS DJANGO REST_FRAMEWORK? (DRF) ‎Django rest_framework is Django's own restful API, it keeps the backend separate from the server but negotiates with the database for information requested by the client through HttpResponses. ‎ ‎It is important to note that all requests are treated individually, and attended to provided the right data has been provided. e.g a new product can be created from the API endpoint provided all the required sections have been filled out as required by the models, the product name, category, description and so on. This is so that a new table is created in the database for that data without need for prior information like user account, or if that product exists prior. it's excellent for debugging and ensuring that the backend actually does what it claims to do. ‎A major part of drf's algorithm is its serializers. Serializers are files that help convert python primitive types/objects into acceptable web formats, e.g JSON, enabling clients to see and interact with resources displayed on the server in json format. As such, creating a new resource will be done using JSON format and saved, the data will then be deserialized/ parsed and sent back to the app where it will be saved on the database. ‎ ‎ let's create a mental flow chart: ‎Serializer initialized --> Server (resource displayed in JSON format.) --> Client requests/inputs data ---> Serializer validates data --> serializer deserializes data --> data gets stored in the database. ‎ So, that's how client-server-database flows occur in Django rest_framework. We are halfway through the series now and we've covered what Django is, when and why you should use Django, how to create projects in Django, what API's and restful API's are, and finally what django rest_framework is. Keep up with me as I continue to break down programming topics, while sharing my personal experience in building projects, with you. ‎ ‎#APIs #webdevelopment #learninginpublic #learninpublic #whydjangorestframework #django #djangrestframework #python #webdev #backenddevelopment

𝗜𝗻𝘁𝗿𝗼𝗱𝗎𝗰𝗶𝗻𝗴 𝗦𝗲𝗿𝗶𝗮𝗹𝗶𝗭𝗲𝗿𝗦 𝗜𝗻 𝗗𝗷𝗮𝗻𝗴𝗼 𝗥𝗲𝘀𝗍 𝗙𝗿𝗮𝗺𝗲𝗪𝗼𝗿𝗸 If you are new to Django Rest Framework, you may find the concept of serializers confusing. In this post, I will break it down in simple terms and show you how to build one from scratch. A serializer is like a bridge between your database and the internet. Django models store data as Python objects. When you want to send that data to a frontend application, you need to send it in a format that everyone understands, which is usually JSON. Serializers perform three main jobs: - Converting complex Python objects into Python dictionaries - Converting JSON data into complex Python objects - Checking if the incoming data is correct before saving it to the database Let's look at a simple scenario. We want to build a store, so we define a ProductModel with fields like name, description, price, stock, and is_active. To send a ProductModel instance to a web browser, we need a translator, which is the serializer. We will create a serializer that mirrors our model. You can learn more about serializers in the Django Rest Framework documentation. Source: https://lnkd.in/dECJbdiA

In the world of Python web development, selecting the appropriate framework can significantly impact your project's efficiency, scalability, and maintainability. Django, FastAPI, and Flask stand out as three of the most popular options, each catering to different needs and philosophies. Django is a full-featured, "batteries-included" framework ideal for complex applications. Flask offers a minimalist, flexible approach for those who prefer building from the ground up. FastAPI, a newer entrant, emphasizes speed, asynchronous capabilities, and API development with modern features like automatic documentation. This article delves into their histories, key features, performance, use cases, pros and cons, and ultimately helps you decide which might suit your next project. #backend #django #fastapi #flask https://lnkd.in/dvQnq66a

Django vs FastAPI: A Side-by-Side Look at Two Popular Python Frameworks Ever wondered how Django and FastAPI stack up against each other? They're both popular Python frameworks, but they serve different purposes and excel in different areas. Here's a quick comparison! 🔶 Django • Type: Full-stack, batteries-included framework • Best for: Monolithic applications, content-heavy sites (CMS, blogs, e-commerce) • Built-in features: Admin panel, ORM, authentication, templating engine • Architecture: MVT (Model-View-Template) • Learning curve: Steeper initially due to many built-in components • Performance: Solid for traditional web applications • API documentation: Third-party packages required (Django REST Framework) 🔶 FastAPI • Type: Modern, lightweight API framework • Best for: High-performance APIs, microservices, real-time applications • Built-in features: Async support, automatic API documentation, data validation • Architecture: ASGI-based, supports async/await • Learning curve: Gentler start, but requires more decisions on architecture • Performance: Excellent for I/O-bound operations and concurrent requests • API documentation: Auto-generated interactive docs (Swagger UI & ReDoc) 📊 Key Differences: • Django follows "batteries-included" philosophy while FastAPI follows "do one thing well" • Django excels in rapid development of full-featured web apps • FastAPI shines in building high-performance APIs with modern Python features • Both have excellent communities and ecosystems 💭 Final Thoughts: Neither is objectively "better" – they're tools designed for different jobs! Django is like a fully-equipped kitchen for cooking complete meals, while FastAPI is like specialized high-tech equipment for specific gourmet dishes. Have you worked with both? What's been your experience?

WHY DJANGO REST_FRAMEWORK? DAY 10: ‎ ‎THE FINAL VERDICT: DJANGO OR DRF? ‎ ‎We’ve spent 10 days breaking this down. From Serializers and Statelessness to Throttling and the Browsable APIs. So, the big question: Should you always use DRF? ‎ ‎The honest answer? No. ‎ ‎Choose Traditional Django if: ‎-- You are building a simple SEO-heavy blog or a site where the server needs to render everything for the browser (Server Side Rendering). ‎-- You don't need a mobile app or a separate frontend like React. ‎-- You want to keep everything "in-house" using Django’s MTV pattern. ‎ ‎Choose Django Rest_Framework if: ‎-- You want a Decoupled Architecture (Backend and Frontend are separate). ‎-- You are building for multiple platforms (Web, iOS, Android). ‎-- You want a scalable, stateless system that handles data like a pro. ‎-- You want to focus purely on logic and data without touching HTML/CSS. ‎ ‎My journey with PollScribe taught me that while DRF has a learning curve (those serializers can be tricky!), the freedom it gives you is unmatched. It forces you to think about your data more clearly and prepares your app for the modern, API-driven world. ‎ ‎This concludes our 10-day series! I hope this helped clear the fog on why DRF is such a powerhouse in the Python ecosystem. ‎ ‎What topic should I dive into next? More deep-dives into Serializers, or maybe a step-by-step project build? Drop your suggestions in the comments! ‎ ‎#APIs #webdevelopment #learninginpublic #learninpublic #whydjangorestframework #django #djangrestframework #python #webdev #backenddevelopment

Stop using SearchFilter for everything in Django. If you are building APIs with Django REST Framework, choosing the wrong filtering strategy is the fastest way to kill your database performance as your data grows. I see many developers defaulting to filters.SearchFilter because it’s easy to setup. But is it always the right choice? Here is the breakdown of SearchFilter vs. CharFilter, and when to use each: 1. The Precision Specialist: CharFilter (icontains) When you want to filter a specific field like "product name" or "email", CharFilter is your best friend. How it works: It maps directly to one field in your model. The Win: It’s predictable. If the user types in the "Title" box, they get results from the "Title" column. Performance: Easier to optimize with database indexes (especially if using istartswith). 2. The Generalist: SearchFilter This is your "Global Search" bar. One input that looks across multiple fields (e.g., searching for a string in name, description, and tags simultaneously). How it works: It uses the search_fields attribute to construct a large OR query. The Risk: As your dataset grows, an OR query across 5 different text columns becomes a performance nightmare. The Win: Great for UX when the user doesn't know exactly where the information is. The Rule of Thumb: - Use CharFilter for structured search (sidebar filters, specific tables, or power-user dashboards). - Use SearchFilter for "Google-like" search bars where the user wants to find a keyword anywhere in the record. If you are using PostgreSQL and your SearchFilter is getting slow, stop using basic lookups and start looking into SearchVector and Full Text Search, it’s a game changer for Django devs. How do you handle search in your Django projects? Do you prefer specific field filters or one big global search bar? 👇 #Django #Python #BackendDevelopment #RESTAPI #WebDevelopment
