📌 Introduction
In Django, the render() function is used to:
- Load an HTML template
- Pass data to it
- Return it as an HTTP response
👉 It is the most commonly used function in Django views.
🎯 Program Statement
👉 Create and render a basic HTML template using Django render() function.
⚙️ Step 1: Create Project and App
django-admin startproject myproject
cd myproject
python manage.py startapp myapp
⚙️ Step 2: Register App
📁 File: settings.py
🔹 Path:
myproject/myproject/settings.py
🔹 Code:
INSTALLED_APPS = [
...
'myapp',
]
⚙️ Step 3: Configure Templates Folder
📁 File: settings.py
🔹 Path:
myproject/myproject/settings.py
🔹 Code:
import os
TEMPLATES = [
{
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
},
]
⚙️ Step 4: Create View using render()
📁 File: views.py
🔹 Path:
myproject/myapp/views.py
🔹 Code:
from django.shortcuts import render
def home(request):
return render(request, 'home.html')
🧠 Explanation
render(request, 'home.html')
- Loads
home.html - Returns it as response
- No data passed here
⚙️ Step 5: URL Mapping
📁 File: urls.py
🔹 Path:
myproject/myproject/urls.py
🔹 Code:
from django.contrib import admin
from django.urls import path
from myapp import views
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.home),
]
⚙️ Step 6: Create Template
📁 File: home.html
🔹 Path:
myproject/templates/home.html
🔹 Code:
<!DOCTYPE html>
<html>
<head>
<title>Home Page</title>
</head>
<body>
<h1>Welcome to Django</h1>
<p>This is my first template rendered using render() function.</p>
</body>
</html>
⚙️ Step 7: Run Server
python manage.py runserver
🌐 Step 8: Output
Open:
✅ Output:
Welcome to Django
This is my first template rendered using render() function.
🧠 How It Works
- User opens
/ - URL calls
home()view - View calls
render() - Django loads
home.html - HTML is displayed in browser
🧠 Syntax of render()
render(request, template_name, context)
Example:
return render(request, 'home.html', {'name': 'Kavita'})
⚠️ Common Errors
❌ Template not found
👉 Check:
templates/home.html
❌ App not registered
👉 Add 'myapp' in INSTALLED_APPS
❌ Wrong template path
👉 Use:
render(request, 'home.html')
NOT:
render(request, '/templates/home.html')
