I’ve been working with Ruby on Rails for a long time, and honestly, it always felt like pure magic.

Rails' elegance, its conventions, the way things just worked with minimal setup. It made development fast and enjoyable.

Recently, I wanted to work with Django (Python’s popular web framework). Especially because of the growing interest in Python and AI.
But when I started, I really missed the convenience and flow that Rails gave me.

So, I started exploring:
How can we get that Rails-like magic in Django too?

Let’s take a look 👇

Serializers — Handling Data Representation

In Rails, we use serializers to control how our model data looks:

# app/serializers/post_serializer.rb
class PostSerializer < ActiveModel::Serializer
  attributes :id, :title, :content
end

In Django, it's similar using Django REST Framework:
First, install the djangorestframework package

pip install djangorestframework

# serializers.py
from rest_framework import serializers
from .models import Post

class PostSerializer(serializers.ModelSerializer):
    class Meta:
        model = Post
        fields = ['id', 'title', 'content']

And how to call those serializers?!.
No worries, we going to see in upcoming.😎

Controllers and Views — Managing Requests

In Rails, we use controllers like this:

# app/controllers/posts_controller.rb
class PostsController < ApplicationController
  def index
    @posts = Post.all
    render json: @posts
  end
end

In Django, you can use ViewSets to do the same:

# views.py
from rest_framework import viewsets
from .models import Post
from .serializers import PostSerializer

class PostViewSet(viewsets.ModelViewSet):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

Auto CRUD — no manual GET, POST, PUT handling! 😃

Routing — Clean and Automatic

In Rails, adding routes is super simple:

# config/routes.rb
resources :posts

In Django, you can achieve the same using DRF’s routers:

# urls.py
from rest_framework.routers import DefaultRouter
from .views import PostViewSet

router = DefaultRouter()
router.register(r'posts', PostViewSet, basename='post')

urlpatterns = router.urls

Resourceful routes with a few lines! ✌️

Callbacks — Hooking into Model Events

In Rails

class Post < ApplicationRecord
  before_save :capitalize_title
end

Django (with signals):

from django.db.models.signals import pre_save
from django.dispatch import receiver

@receiver(pre_save, sender=Post)
def capitalize_title(sender, instance, **kwargs):
    instance.title = instance.title.capitalize()

✅Behavior before/after saving models — sorted!

Validations — Ensuring Data Integrity

In Rails

class Post < ApplicationRecord
  validates :title, presence: true
end

In Django

from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=100)

    def clean(self):
        if not self.title:
            raise ValidationError('Title cannot be empty')

Django models come with built-in validation hooks.
(Also, Django’s CharField automatically validates max_length like Rails does!)

Wrapping Up

Even though Rails and Django have different styles, you can recreate almost all of Rails' magic in Django — once you know where to look!

From serializers, viewsets, routers, callbacks, validations, and beyond — Django can feel just as developer-friendly as Rails.

And this is just the beginning!

In upcoming parts, we'll dive deeper into topics like building APIs, authentication, background jobs, and more.
