Django Framework & MVT Pattern
Develop large-scale, robust web applications with the feature-rich Django framework.
Batteries Included
Django is a "high-level Python web framework that encourages rapid development and clean, pragmatic design." It includes an ORM, auth system, admin interface, and more out of the box.
The MVT Pattern
- Model: Defines the data structure (database abstraction).
- View: Handles business logic and returns a response.
- Template: Handles the presentation layer (HTML).
Creating a Model
from django.db import models
class Post(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title
class Post(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title
Writing a View
from django.shortcuts import render
from .models import Post
def post_list(request):
posts = Post.objects.all()
return render(request, 'blog/post_list.html', {'posts': posts})
from .models import Post
def post_list(request):
posts = Post.objects.all()
return render(request, 'blog/post_list.html', {'posts': posts})
The Admin Interface
Register your models to see them in the automatically generated admin site.
from django.contrib import admin
from .models import Post
admin.site.register(Post)
from .models import Post
admin.site.register(Post)
