How to convert from Python to Ruby on Rails

Introduction: Free Python to Ruby on Rails Code Converter

When making the switch from one programming language to another, it can often be daunting and time-consuming, especially if you're transitioning from Python to Ruby on Rails. This guide aims to serve as a free resource for converting your Python code to Ruby on Rails. If you're already proficient in Python but need to adapt your skills for a Ruby on Rails application, read on to make that transition smoother and more efficient.

Understanding the Basics: Python vs Ruby on Rails

Before diving into the conversion process, it's essential to understand the fundamental differences between Python and Ruby on Rails:

  • Python: A versatile and widely-used programming language known for its readability and simplicity. Python is often used for data science, scripting, and web development (commonly with frameworks like Django or Flask).
  • Ruby on Rails: A powerful web application framework written in Ruby. Rails follow the convention over configuration paradigm and are optimized for programmer happiness and sustainable productivity.

Key Structural Differences

Syntax and Semantics

One of the first things to get accustomed to is the difference in syntax and semantics between Python and Ruby on Rails:

  • Python uses indentation to denote code blocks, while Ruby uses end keywords.
  • Python employs def to define functions and methods, whereas Ruby utilizes def and end.

Here’s a simple example to highlight these differences:


def hello_world():
    print("Hello, World!")


def hello_world
  puts "Hello, World!"

Object-Oriented Differences

Both Python and Ruby are object-oriented languages, but Ruby tends to be more object-oriented in practice.


class Person:
    def __init__(self, name): = name

    def greet(self):
        return f"Hello, {}"


class Person
  def initialize(name)
    @name = name

  def greet
    "Hello, #{@name}"

Converting Data Models

A common task in both Python and Ruby on Rails is the handling of data models, often backed by databases.

Python (Django)

from django.db import models

class Person(models.Model):
    name = models.CharField(max_length=100)

Ruby on Rails

class CreatePersons < ActiveRecord::Migration[6.0]
  def change
    create_table :persons do |t|
      t.string :name


class Person < ApplicationRecord

In this example, the Ruby on Rails code covers both database migration and model definition.

Routes and URL Handling

Handling routes in Python (using Flask) and Ruby on Rails is another crucial difference:

Python (Flask)

from flask import Flask

app = Flask(__name__)

def home():
    return "Hello, World!"

if __name__ == '__main__':

Ruby on Rails

Rails.application.routes.draw do
  root 'welcome#index'

class WelcomeController < ApplicationController
  def index
    render plain: "Hello, World!"

Template Engines

When it comes to rendering UI, Python typically uses Jinja2 templates while Ruby on Rails uses ERB:

Python (Jinja2)

<!DOCTYPE html>
    <title>{{ title }}</title>
    <h1>{{ header }}</h1>
    <p>{{ content }}</p>

Ruby on Rails (ERB)

<!DOCTYPE html>
    <title><%= @title %></title>
    <h1><%= @header %></h1>
    <p><%= @content %></p>

Key Libraries and Gems

The transition to Ruby on Rails will also involve switching to different libraries or "gems":

  • Requests (Python) -> HTTParty (Ruby)
  • Pandas (Python) -> ActiveRecord or Sequel (Ruby)
  • NumPy (Python) -> Ruby's native numerical methods or use specific gems like Numpy.rb.
