How to convert from Ruby to Laravel

Transitioning from Ruby to Laravel can be an enriching yet challenging experience. This guide will walk you through the essentials of converting Ruby code into the Laravel framework, tailored for those proficient in Ruby but new to Laravel.

Introduction to Laravel

Laravel is a powerful PHP framework designed to make web development easier and more structured. Known for its elegant syntax, robust tools, and powerful features, Laravel can seem daunting coming from Ruby, but the transition is manageable with a clear roadmap.

Environment Setup

Before diving into the conversion, setting up the Laravel environment is crucial:

  1. Install Composer: Laravel relies heavily on Composer for dependency management.
  2. Install Laravel: You can install Laravel by using Composer with the command composer global require laravel/installer.
  3. Set Up a Laravel Project: Run laravel new projectname to create a new Laravel project.

Routing

In Ruby, routes are defined in config/routes.rb. Conversely, Laravel uses routes/web.php for managing routes.

# Ruby
get 'welcome/index'

Converted to Laravel:

// Laravel
Route::get('/welcome', 'WelcomeController@index');

Controllers

Rails controllers are located in app/controllers, whereas Laravel places them in app/Http/Controllers.

Ruby Controller:

class WelcomeController < ApplicationController
  def index
  end
end

Converted to Laravel Controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class WelcomeController extends Controller
{
    public function index()
    {
        //
    }
}

Views

Ruby views are found in app/views, while Laravel views reside in resources/views.

Ruby View (ERB):
<!-- app/views/welcome/index.html.erb -->
<h1>Hello, world!</h1>
Laravel View (Blade):
<!-- resources/views/welcome.blade.php -->
<h1>Hello, world!</h1>

Models and Database Migrations

Models in Ruby are in app/models, and migrations are in db/migrate. Laravel models are in app/Models, and migrations are in database/migrations.

Ruby Model:

class Post < ApplicationRecord
end

Converted to Laravel Model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;
}

Ruby Migration:

class CreatePosts < ActiveRecord::Migration[6.0]
  def change
    create_table :posts do |t|
      t.string :title
      t.text :body

      t.timestamps
    end
  end
end

Converted to Laravel Migration:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePostsTable extends Migration
{
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->text('body');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

Adding Functionality

Ruby Method:

def greet(name)
  "Hello, #{name}!"
end

Converted to Laravel Method:

public function greet($name)
{
    return "Hello, {$name}!";
}

Dependency Management

Ruby uses Bundler for dependency management, while Laravel utilizes Composer.

Gemfile:

gem 'rails', '~> 6.0.3'

Composer.json:

{
    "require": {
        "laravel/framework": "^8.0"
    }
}

Middleware

Ruby on Rails middleware is found in app/middleware, while Laravel middleware is in app/Http/Middleware.

Ruby Middleware:

class Authentication
  def initialize(app)
    @app = app
  end

  def call(env)
    # Middleware logic
    @app.call(env)
  end
end

Converted to Laravel Middleware:

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class Authenticate
{
    public function handle(Request $request, Closure $next)
    {
        // Middleware logic
        return $next($request);
    }
}

Conclusion

Transitioning from Ruby to Laravel involves understanding the architectural and syntactical differences between the two frameworks. This guide on using a Free Ruby to Laravel Code Converter provides the basic roadmap for transitioning your code. Although these examples highlight core concepts, further study and experience will ensure a smoother transition.
