Lumen generators

Build Status Scrutinizer Code Quality SensioLabsInsight License

A collection of generators for Lumen and Laravel 5.

Contents

Why ?

I installed Lumen and wanted to use it to create a REST API (since this is the main usage of Lumen). But I didn't find commands which will speed up my workflow. That's why I created this package and included useful commands to build a RESTful API.

This packages was mainly built to be used with Lumen, but it should work fine with Laravel 5 too.

Installation

Add the generators package to your composer.json by running the command:

composer require wn/lumen-generators

Then add the service provider in the file app/Providers/AppServiceProvider.phplike the following:

public function register()
{
    if ($this->app->environment() == 'local') {
        $this->app->register('Wn\Generators\CommandsServiceProvider');
    }
}

Don't forget to include the application service provider on your bootstrap/app.php and to enable Eloquent and Facades if you are using Lumen

If you run the command php artisan list you will see the list of added commands:

wn:controller               Generates RESTful controller using the RESTActions trait
wn:controller:rest-actions  Generates REST actions trait to use into controllers
wn:migration                Generates a migration to create a table with schema
wn:model                    Generates a model class for a RESTfull resource
wn:pivot-table              Generates creation migration for a pivot table
wn:resource                 Generates a model, migration, controller and routes for RESTful resource
wn:resources                Generates multiple resources from a file
wn:route                    Generates RESTful routes.

Quick Usage

To generate a RESTful resource for your application (model, migration, controller and RESTful routes), you simply need to run one single command. For example:

php artisan wn:resource task "name;string;required;fillable project_id;integer:unsigned;numeric;fillable,key due;date;;date" --add=timestamps --belongs-to=project

will generate these files:

app/Task.php

<?php namespace App;

use Illuminate\Database\Eloquent\Model;

class Task extends Model {

	protected $fillable = ["name", "project_id"];

	protected $dates = ["due"];

	public static $rules = [
		"name" => "required",
		"project_id" => "numeric",
	];

	public function project()
	{
		return $this->belongsTo("App\Project");
	}

}

app/Http/Controllers/RESTActions.php

<?php namespace App\Http\Controllers;

use Illuminate\Http\Request;


trait RESTActions {

	protected $statusCodes = [
		'done' => 200,
		'created' => 201,
		'removed' => 204,
		'not_valid' => 400,
		'not_found' => 404,
		'conflict' => 409,
		'permissions' => 401
	];

	public function all()
	{
		$m = self::MODEL;
		return $this->respond('done', $m::all());
	}

	public function get($id)
	{
		$m = self::MODEL;
		$model = $m::find($id);
		if(is_null($model)){
			return $this->respond('not_found');
		}
		return $this->respond('done', $model);
	}

	public function add(Request $request)
	{
		$m = self::MODEL;
		$this->validate($request, $m::$rules);
		return $this->respond('created', $m::create($request->all()));
	}

	public function put(Request $request, $id)
	{
		$m = self::MODEL;
		$this->validate($request, $m::$rules);
		$model = $m::find($id);
		if(is_null($model)){
			return $this->respond('not_found');
		}
		$model->update($request->all());
		return $this->respond('done', $model);
	}

	public function remove($id)
	{
		$m = self::MODEL;
		if(is_null($m::find($id))){
			return $this->respond('not_found');
		}
		$m::destroy($id);
		return $this->respond('removed');
	}

    protected function respond($status, $data = [])
    {
    	return response()->json($data, $this->statusCodes[$status]);
    }

}

app/Http/Controllers/TasksController.php

<?php namespace App\Http\Controllers;


class TasksController extends Controller {

	const MODEL = "App\Task";

	use RESTActions;

}

app/Http/routes.php

// These lignes will be added
/**
 * Routes for resource task
 */
$app->get('task', 'TasksController@all');
$app->get('task/{id}', 'TasksController@get');
$app->post('task', 'TasksController@add');
$app->put('task/{id}', 'TasksController@put');
$app->delete('task/{id}', 'TasksController@remove');

database/migrations/date_time_create_tasks.php

<?php

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

class CreateTasksMigration extends Migration
{
    
    public function up()
    {
        Schema::create('tasks', function(Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->integer('project_id')->unsigned();
            $table->date('due');
            $table->foreign('project_id')
                ->references('id')
                ->on('projects');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::drop('tasks');
    }
}

Now simply run the migration and you are ready to go.

More then that, you can generate multiple resources with only one command ! Click here to see an example

Detailed Usage

Model Generator

The wn:model command is used to generate a model class based on Eloquent. It has the following syntax:

wn:model name [--fillable=...] [--dates=...] [--has-many=...] [--has-one=...] [--belongs-to=...] [--belongs-to-many=...] [--rules=...] [--timestamps=false] [--path=...] [--soft-deletes=true] [--force=true]

php artisan wn:model Task generates the following:

<?php namespace App;

use Illuminate\Database\Eloquent\Model;

class Task extends Model {

	protected $fillable = [];

	protected $dates = [];

	public static $rules = [
		// Validation rules
	];

	// Relationships

}

php artisan wn:model Task --fillable=name,title gives:

//...	
	protected $fillable = ['name', 'title'];

php artisan wn:model Task --dates=started_at,published_at gives:

//...	
	protected $dates = ['started_at', 'published_at'];

php artisan wn:model Task --path="app/Http/Models" gives:

<?php namespace App\Http\Models;
//...

php artisan wn:model Task --has-many=accounts --belongs-to="owner:App\User" --has-one=number:Phone belongs-to-many=tags --path=tests/tmp

gives:

//...
	public function accounts()
	{
		return $this->hasMany("Tests\Tmp\Account");
	}

	public function owner()
	{
		return $this->belongsTo("App\User");
	}

	public function number()
	{
		return $this->hasOne("Tests\Tmp\Phone");
	}

	public function tags()
	{
		return $this->belongsToMany("Tests\Tmp\Tag")->withTimestamps();
	}

php artisan wn:model TestingModel --rules="name=required age=integer|min:13 email=email|unique:users,email_address"`

gives:

// ...
	public static $rules = [
		"name" => "required",
		"age" => "integer|min:13",
		"email" => "email|unique:users,email_address",
	];

TestingModel model already exists; use --force option to override it !

Migration Generator

The wn:migration command is used to generate a migration to create a table with schema. It has the following syntax:

wn:migration table [--schema=...] [--add=...] [--keys=...] [--force=true] [--file=...]

php artisan wn:migration tasks --schema="amount:decimal.5,2:after.'size':default.8 title:string:nullable"

gives:

<?php

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

class CreateTasksMigration extends Migration
{
    
    public function up()
    {
        Schema::create('tasks', function(Blueprint $table) {
            $table->increments('id');
            $table->decimal('amount', 5, 2)->after('size')->default(8);
            $table->string('title')->nullable();
            // Constraints declaration

        });
    }

    public function down()
    {
        Schema::drop('tasks');
    }
}

php artisan wn:migration tasks --keys="category_type_id user_id:identifier:members:cascade"

gives:

//...
$table->foreign('category_type_id')
    ->references('id')
    ->on('category_types');

$table->foreign('user_id')
    ->references('identifier')
    ->on('members')
    ->onDelete('cascade');

Pivot Table Generator

The wn:pivot-table command is used to generate a migration to create a pivot table between two models. It has the following syntax:

wn:pivot-table model1 model2 [--add=...] [--force=true] [--file=...]

php artisan wn:pivot-table Tag Project --add=timestamps

gives:

<?php

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

class CreateProjectTagMigration extends Migration
{
    
    public function up()
    {
        Schema::create('project_tag', function(Blueprint $table) {
            $table->increments('id');
            $table->integer('project_id')->unsigned()->index();
            $table->integer('tag_id')->unsigned()->index();
            $table->foreign('project_id')
                ->references('id')
                ->on('projects');
            $table->foreign('tag_id')
                ->references('id')
                ->on('tags');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::drop('project_tag');
    }
}

Controller Generator

There are two commands for controllers. The first one is wn:controller:rest-actions which generates a trait used by all generated controllers. This trait includes the following methods:

Note that the trait doesn't use the common used methods on Laravel (like index, store, ...) to avoid conflicts. Which enables you to use this trait with controllers you already have in your application.

The second command is wn:controller which actually generates the controller. The syntax of this command is wn:controller model [--no-routes] [--force=true].

php artisan wn:controller Task --no-routes gives:

<?php namespace App\Http\Controllers;


class TasksController extends Controller {

	const MODEL = "App\\Task";

	use RESTActions;

}

Routes Generator

The wn:route command is used to generate RESTfull routes for a controller. It has the following syntax:

wn:route resource [--controller=...] [--force=true]

php artisan wn:route project-type adds the following routes:

$app->get('project-type', 'ProjectTypesController@all');
$app->get('project-type/{id}', 'ProjectTypesController@get');
$app->post('project-type', 'ProjectTypesController@add');
$app->put('project-type/{id}', 'ProjectTypesController@put');
$app->delete('project-type/{id}', 'ProjectTypesController@remove');

php artisan wn:route project-type --laravel adds the following routes:

Route::get('project-type', 'ProjectTypesController@all');
Route::get('project-type/{id}', 'ProjectTypesController@get');
Route::post('project-type', 'ProjectTypesController@add');
Route::put('project-type/{id}', 'ProjectTypesController@put');
Route::delete('project-type/{id}', 'ProjectTypesController@remove');

Resource Generator

The wn:resource command makes it very easy to generate a RESTful resource. It generates a model, migration, controller and routes. The syntax is : wn:resource name fields [--add=...] [--has-many=...] [--has-one=...] [--belongs-to=...] [--migration-file=...] [--path=...] [--force=true]

Multiple Resources From File

The wn:resources (note the "s" in "resources") command takes the generation process to an other level by parsing a file and generating multiple resources based on it. The syntax is

wn:resources filename [--path=...] [--force=true]

This generator is smart enough to add foreign keys automatically when finding a belongsTo relation. It also generates pivot tables for belongsToMany relations automatically.

The file given to the command should be a valid YAML file ( for the moment, support of other types like XML or JSON could be added in the future). An example is the following:

---
Store:
  hasMany: products
  fields:
    name:
      schema: string:50 unique
      rules: required|min:3
      tags: fillable
Product:
  belongsTo: store
  fields:
    name:
      schema: string
      rules: required
      tags: fillable
    store_id:
      schema: integer unsigned
      rules: required numeric
      tags: fillable key
    desc:
      schema: text nullable
      tags: fillable
    published_at:
      schema: date
      rules: date
      tags: date fillable
    price:
      schema: 'decimal:5,2' # need quotes when using ','
      rules: numeric
      tags: fillable
  add: timestamps softDeletes

Testing

To test the generators, I included a fresh lumen installation under the folder lumen-test to which I added this package and have written some acceptance tests using Codeception. To run tests you just have to execute the install.sh to install dependencies then execute test.sh.
