Django

Views

A view is a Python function (or class) that receives an incoming request and returns a response.

Example: a view listing posts, newest first

# blog/views.py
from django.shortcuts import render
from .models import Post

def post_list(request):
    posts = Post.objects.all().order_by('-published_at')
    return render(request, 'blog/post_list.html', {'posts': posts})

Renders the blog/post_list.html template with every Post, newest
first, available as {{ posts }}.

Post.objects.all().order_by('-published_at') is Django's ORM, the same kind of query you saw in the SQL tutorial's ORDER BY lesson, expressed as Python method calls instead of a raw SQL string. The leading - before published_at means descending order, exactly matching SQL's ORDER BY published_at DESC. render() is the bridge between a view's Python data and the actual HTML template that displays it, covered properly two lessons from now.

# blog/views.py
from django.shortcuts import render
from .models import Post

def post_list(request):
    posts = Post.objects.all().order_by('-published_at')
    return render(request, 'blog/post_list.html', {'posts': posts})

Renders the blog/post_list.html template with every Post, newest first, available as {{ posts }}.
