📌 Introduction

Django provides a powerful Admin Interface that allows you to:

• view records
• add new data
• update records
• delete records

👉 But for this, the model must be registered in admin.py.

---

🎯 Program Statement

👉 Register a model in Django admin and display records.

---

🧠 Concept

This program uses:

• models.py → database structure
• admin.py → model registration
• Django admin panel

---

⚙️ Step 1: Model (Already Created)

---

📁 File: models.py

🔹 Path:

myproject/myapp/models.py

---

🔹 Code:

from django.db import models

class Student(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField()
    course = models.CharField(max_length=100)
    email = models.EmailField(unique=True)

    def __str__(self):
        return self.name

---

⚙️ Step 2: Register Model in Admin

---

📁 File: admin.py

🔹 Path:

myproject/myapp/admin.py

---

🔹 Code:

from django.contrib import admin
from .models import Student

admin.site.register(Student)

---

🧠 Explanation

• admin.site.register(Student) makes the model visible in admin panel
• Without this, model will not appear in admin

---

⚙️ Step 3: Run Server

python manage.py runserver

---

⚙️ Step 4: Open Admin Panel

👉 Open:

http://127.0.0.1:8000/admin/

---

⚙️ Step 5: Login

👉 Use superuser credentials

(If not created, see next post 👇)

---

🌐 Step 6: Output

After Login:

You will see:

MYAPP
   Students

---

Click “Students”

👉 You will see:

• list of student records
• Add button
• Edit option

---

Click “Add Student”

Form appears like:

Name: ______
Age: ______
Course: ______
Email: ______

---

After Saving:

Records will be displayed in admin list.

---

🧠 How It Works

1. Model defines database table
2. Admin registers the model
3. Django automatically generates admin UI
4. You can perform CRUD operations directly

---

🔥 Key Concepts

admin.site.register(Student)

---

Admin Panel URL

---

Model Display

def __str__(self):
    return self.name
