Day-123 📘 Python Full Stack Journey – Django CRUD (Create Operation) Today I started implementing CRUD operations in Django, beginning with the Create functionality by building an Employee Registration Form. 🚀 🎯 What I learned today: 🗄️ Model Creation Created an Employee model to store user data: Full Name Employee ID Phone Number Email ID 🌐 Form Creation (Manual HTML Form) Built a registration form using HTML Used: method="post" {% csrf_token %} for security Input validation with required attributes ⚙️ Handling Form Data in Views Captured user input using request.POST Created an object and saved data into the database: ob = Employee() ob.fullname = username ob.emp_id = empid ob.ph_no = phno ob.email_id = emailid ob.save() 🔗 Routing & Navigation Connected form via URL routing Added navigation link in base.html This session helped me understand how Django handles data creation from user input, a key part of real-world applications. Looking forward to implementing the remaining CRUD operations — Read, Update, and Delete! 💻✨ #Django #Python #FullStackDevelopment #WebDevelopment #CRUD #BackendDevelopment #CodingJourney #LearningToCode #Upskilling #ContinuousLearning

Day-129 📘 Python Full Stack Journey – Django Messages & Authentication Flow 🔐 Today I enhanced my Django application by implementing user feedback messages and complete authentication flow (Login & Logout). 🚀 🎯 What I learned today: 💬 Django Messages Framework Displayed success messages after signup using: messages.success(request, f'Account created for {username}!') Rendered messages in HTML using: {% if messages %} {% for message in messages %} <p style="color: green;">{{ message }}</p> {% endfor %} {% endif %} 💡 This improves user experience by giving instant feedback. 🔐 Login Using AuthenticationForm Used Django’s built-in AuthenticationForm Accessed form fields directly in template: {{ form.username }} {{ form.password }} Validated and authenticated users securely 🚪 Logout Functionality Implemented logout using: from django.contrib.auth import logout def logout_view(request): logout(request) return redirect('Login') Added logout route and link in UI ⚙️ Key Takeaways Improved user interaction with messages Built a complete authentication cycle (Signup → Login → Logout) Learned how Django handles sessions and user state This session made my application more user-friendly, secure, and complete. Excited to keep improving with protected routes and user-specific data next! 💻✨ #Django #Python #FullStackDevelopment #WebDevelopment #Authentication #Login #Logout #UserExperience #CodingJourney #LearningToCode #Upskilling #ContinuousLearning

Day-120,121 📘 Python Full Stack Journey – Django Forms & User Input Handling Today I learned how to handle user input in Django using models and forms — an important step toward building interactive and data-driven applications. 🚀 🎯 What I learned today: 🗄️ Model Creation (Contact Form) Created a Contact model to store user data: Name Email Phone number Applied migrations and registered the model in Django Admin for easy data management 📝 Django ModelForm Created a form using Django’s built-in ModelForm: class BookingContact(forms.ModelForm): class Meta: model = Contact fields = '__all__' Learned how Django automatically generates form fields from models 🌐 Displaying Forms in Templates Rendered forms in HTML using: {{ form }} {{ form.as_p }} for structured layout 📩 Form Submission (POST Method) Used POST method for secure data submission Added {% csrf_token %} for protection Handled form submission in views.py: if request.method == 'POST': form = BookingContact(request.POST) if form.is_valid(): form.save() 🎨 Custom Form Styling Styled individual form fields manually using labels and inputs Learned how to design forms for better user experience This session helped me understand how Django manages forms, validation, and database storage seamlessly — a key step in building real-world web applications. Excited to keep building more interactive features! 💻✨ #Django #Python #FullStackDevelopment #WebDevelopment #Backend #Forms #Database #CodingJourney #LearningToCode #Upskilling #ContinuousLearning

Optimizing Django Queries: How to Avoid N+1 Problems One of the quickest ways to slow down your Django backend is the classic N+1 query issue. While working on Inboxit, I had to be deliberate about this especially when dealing with relationships between models. The fix I use most often: prefetch_related() It’s perfect for optimizing reverse relationships (when you have a ForeignKey pointing to your model and you need to access related data). Instead of making one query per object (which explodes with more records), prefetch_related fetches all the related data in just two queries one for the main objects and one for the related ones. This small change keeps response times fast and your API scalable as usage grows. Have you run into N+1 issues in your Django projects?

A Python package to clean Django project junk and free space. Over time, my projects kept filling up with things I don’t actually need… __pycache__, .pyc files, logs, staticfiles, even old virtual environments. Cleaning them manually every time was just… annoying 😅 So I made something simple to handle it. 🧹 Django Cleaner It scans your folders, detects Django projects automatically, and removes all the unnecessary stuff safely — without touching your actual code. You just run: django-cleaner ~/Projects and it does the rest. What it handles: • Removes __pycache__ and .pyc files • Cleans logs and staticfiles • Optional removal of venv • Shows how much space you freed I kept it simple on purpose. No setup, no complexity — just something useful that works. Published it on PyPI 📦 🔗 https://lnkd.in/gSvj5U3Y Code on GitHub 👇 🔗 https://lnkd.in/gNur8fN3 This is one of those small things that actually makes working on multiple projects easier. If you use Django, it might help you too. #Python #Django #OpenSource #BuildInPublic #SoftwareDevelopment #BackendDevelopment #DeveloperTools #Programming #Tech #CleanCode #Productivity #CodingLife

This one Django mistake made my query 12 seconds slow, and I realize it for hours.... 12 seconds… for a simple page. At first, I thought: “Maybe my system is slow.” But the real problem was my query. Here’s what was wrong 👇 I was doing this: • Fetching all records • Looping in Python to filter data • Multiple DB hits inside a loop Basically… I made Django work harder than needed. Here’s what fixed it: ✅ Used `select_related()` to reduce joins ✅ Used `prefetch_related()` for reverse relations ✅ Moved filtering logic into the database ✅ Avoided unnecessary loops Result? ⚡ Query time dropped from 12 sec → under 1 sec Big lesson: If your Django app feels slow, don’t blame Django… Check how you’re querying the database. Most of the time, the problem is not the framework — it’s the query. Have you ever faced slow queries in Django? What was your fix? #django #backend #python #query #developer

Day 02 of 30 | Django MVT Pattern 🐍 Before writing any code in Django, you need to understand how it thinks. MVT = Model + View + Template. Every request your user makes follows this exact flow: → Browser sends a request → urls.py routes it to the right View → View asks the Model for data → Model queries the database → View sends data to the Template → Template renders HTML and returns it to the browser I made a video explaining each part. My English is A2. The diagram helps. 👀 #Django #Python #30DaysOfDjango #LearningInPublic #Developer #SaaS
