How to convert from Laravel to Ruby

Converting a Laravel application to Ruby can be a daunting task, but it becomes manageable if you break it down into smaller, systematic steps. This guide will walk you through each essential phase, ensuring you successfully migrate your Laravel project to a Ruby-based framework.

Understanding the Differences Between Laravel and Ruby

Before starting the conversion, it's crucial to understand the structural and syntactical differences between Laravel (a PHP framework) and Ruby (a programming language often paired with the Rails framework).

  • Laravel: A feature-rich MVC framework in PHP, designed to facilitate easier and faster web development.
  • Ruby: An object-oriented language known for its simplicity and productivity. Usually paired with Ruby on Rails (RoR) for web development.

Setting Up Your Ruby Environment

Begin by ensuring you have a proper development environment for Ruby set up on your machine.

  1. Install Ruby:
    rbenv install 3.0.0
    rbenv global 3.0.0
  2. Install Rails:
    gem install rails
  3. Create a New Rails Application:
    rails new your_app_name
    cd your_app_name

Database Configuration

Laravel typically uses Eloquent ORM for database handling, whereas in Ruby, ActiveRecord is the norm.

  1. Migrate Database Schema:

    • Examine your Laravel migrations located in the database/migrations directory.
    • Translate each Laravel migration to a corresponding Rails migration. For example:
      class CreateUsers < ActiveRecord::Migration[6.0]
        def change
          create_table :users do |t|
            t.string :name
            t.string :email
  2. Run Migrations in Rails:

    rails db:migrate

Converting Routes and Controllers

Routes in Laravel are defined in routes/web.php, and controllers extend a base controller class. In Ruby on Rails, these are handled slightly differently.

  1. Transform Routes:

    • Laravel route example:
      Route::get('/users', [UserController::class, 'index']);
    • Rails route equivalent:
      # config/routes.rb
      resources :users, only: [:index]
  2. Translate Controllers:

    • Laravel controller:
      class UserController extends Controller {
          public function index() {
              $users = User::all();
              return view('users.index', compact('users'));
    • Rails controller:
      class UsersController < ApplicationController
        def index
          @users = User.all

Converting Models

Both Laravel and Rails use object-relational mapping (ORM) extensively but with different nomenclatures and conventions.

  1. Eloquent to ActiveRecord:
    • Laravel model example:
      class User extends Model {
          protected $fillable = ['name', 'email'];
    • Rails model equivalent:
      class User < ApplicationRecord
        validates :name, presence: true
        validates :email, presence: true, uniqueness: true

View Conversion

Laravel uses Blade templates for views, while Rails uses Embedded Ruby (ERB).

  1. Blade to ERB:
    • Blade syntax:
      @foreach ($users as $user)
          <p>{{ $user->name }}</p>
    • ERB syntax:
      <% @users.each do |user| %>
          <p><%= %></p>
      <% end %>

Middleware and Helpers

Middleware in Laravel is comparable to Rails' middleware, but the creation and usage are different.

  1. Converting Middleware:
    • Laravel Middleware:
      public function handle($request, Closure $next) {
          if (condition) {
              return response('Unauthorized.', 401);
          return $next($request);
    • Rails Middleware:
      class CustomMiddleware
        def initialize(app)
          @app = app
        def call(env)
          request =
          if condition
            [401, {'Content-Type' => 'text/plain'}, ['Unauthorized']]
      # Add to middleware stack in config/application.rb
      config.middleware.use "CustomMiddleware"


Laravel uses PHPUnit for testing, whereas Rails uses Minitest or RSpec.

  1. Converting Tests:
    • Laravel Test:
      public function test_user_creation() {
          $response = $this->post('/users', ['name' => 'John Doe']);
    • Rails Example (using RSpec):
      require 'rails_helper'
      RSpec.describe "Users", type: :request do
        it "creates a new user" do
          post '/users', params: { user: { name: 'John Doe' } }
          expect(response).to have_http_status(201)

Final Steps

After converting all parts of your Laravel application to Ruby, thoroughly test the new Ruby application to ensure all functionalities work correctly. Utilize Ruby's testing frameworks and tools to identify and fix any issues promptly.


By following these structured steps, you will be able to effectively convert your Laravel application to Ruby. While the transition requires a deep understanding of both frameworks, dividing the process into manageable sections can significantly ease the conversion effort.meta description: A step-by-step guide on how to convert Laravel to Ruby, covering the setup, database configuration, routes, controllers, models, views, middleware, and testing procedures.
