In this tutorial, you’ll learn how to insert data into a PostgreSQL database using Django ORM by capturing values from a GET request, saving them through a model, and displaying a success status page.

This is a beginner-friendly yet real-world Django example, perfect for understanding how URLs, views, models, templates, and ORM work together.

📌 What You’ll Learn in This Video

✅ How Django ORM works with PostgreSQL
✅ How to insert data using Django models
✅ How to read data from request.GET
✅ How to create a custom insert URL
✅ How to render a success page after insertion
✅ How to verify inserted data in PostgreSQL

🧩 Django ORM Insert Data – Step by Step Guide

🔹 Step 1: Create URL Pattern (myapp/urls.py)

Define a custom URL to trigger the insert operation:
path('insert_std_data/', views.insert_student_data)
📌 This URL will accept data via query parameters.

🔹 Step 2: Create Django View to Insert Data

Inside views.py, create the function to capture GET data and save it using ORM:

def insert_student_data(request):
std = Student()
std.std_name = request.GET.get('std_name')
std.username = request.GET.get('username')
std.password = request.GET.get('password')
std.save()
return render(request, 'status.html')

🧠 What’s happening here?

request.GET.get() fetches values from the URL
ORM creates and saves a new record
save() inserts data into PostgreSQL
A success page is rendered

🔹 Step 3: Example URL to Insert Data

Open your browser and use this format:
/insert_std_data/?std_name=Guhan&username=root&password=1234

📌 Data is now passed directly from the URL to the database.

🔹 Step 4: Create status.html Template

Inside the templates folder, create status.html:

Success


✔ This confirms the data was inserted successfully.

🔹 Step 5: Verify Data in PostgreSQL

Run the query in pgAdmin or psql:

SELECT * FROM Student;

🎉 You’ll see the newly inserted row in your database table.

🚀 Why Use Django ORM for Insert Operations?

✔ No raw SQL required
✔ Secure and readable code
✔ Database-independent
✔ Faster development
✔ Industry-standard approach
