Lumen generators
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
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
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
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
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]
- name: the name of the model.
php artisan wn:model Task generates the following:
namespace App;
use Illuminate\Database\Eloquent\Model;
class Task extends Model {
protected $fillable = [];
protected $dates = [];
public static $rules = [
// Validation rules
];
// Relationships
}
- --fillable: the mass fillable fields of the model separated with commas.
php artisan wn:model Task --fillable=name,title gives:
//...
protected $fillable = ['name', 'title'];
- --dates: the date fields of the model, these will be converted automatically to
Carboninstances on retrieval.
php artisan wn:model Task --dates=started_at,published_at gives:
//...
protected $dates = ['started_at', 'published_at'];
- --path: specifies the path where to store the model php file. This path is used to know the namespace of the model. The default value is "app".
php artisan wn:model Task --path="app/Http/Models" gives:
namespace App\Http\Models;
//...
- --has-one, --has-many, --belongs-to and --belongs-to-many: the relationships of the model following the syntax
relation1:model1,relation2:model2,.... If themodelis missing, it will be deducted from the relation's name. If themodelis given without a namespace, it will be considered having the same namespace as the model being generated.
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();
}
- --rules: specifies the validation rules of the model's fields. The syntax is
field1=rules1 field2=rules2 ....
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",
];
-
--timestamps: Enables timestamps on the model. Giving
--timestamps=falsewill addpublic $timestamps = false;to the generated model. The default value istrue. -
--soft-deletes: Adds
Illuminate\Database\Eloquent\SoftDeletestrait to the model. This is disabled by default. -
--force: tells the generator to override the existing file. By default, if the model file already exists, it will not be overriden and the output will be something like:
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=...]
-
table: the name of the table to create.
-
--file: The migration file name (to speicify only for testing purpose). By default the name follows the patern
date_time_create_tableName_table.php. -
--schema: the schema of the table using the syntax
field1:type.arg1,ag2:modifier1:modifier2.. field2:.... Thetypecould betext,string.50,decimal.5,2for example. Modifiers can beuniqueornullablefor example. See documentation for the list of available types and modifiers.
php artisan wn:migration tasks --schema="amount:decimal.5,2:after.'size':default.8 title:string:nullable"
gives:
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');
}
}
-
--add: Specifies additional columns like
timestamps,softDeletes,rememberTokenandnullableTimestamps. -
--keys: the foreign keys of the table following the syntax
field:column:table:on_delete:on_update .... Thecolumnis optional ("id" by default). Thetableis optional if the field follows the naming conventionsingular_table_name_id.on_deleteandon_updateare optional too.
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=...]
-
model1 and model2: names of the two models (or the two tables if the models don't follow the naming conventions)
-
--add: Specifies additional columns like
timestamps,softDeletes,rememberTokenandnullableTimestamps. -
--file: The migration file name. By default the name follows the patern
date_time_create_table_name.php.
php artisan wn:pivot-table Tag Project --add=timestamps
gives:
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');
$table->timestamps();
});
}
public function down()
{
Schema::drop('project_tag');
}
}
Controller Generator
There are two commands for controllers. The first one is wn:controller:rest-actions which generates a trait used by all generated controllers. This trait includes the following methods:
-
all(): returns all the model entries as JSON. -
get($id): returns a specific model by id as JSON. -
add(Request $request): adds a new model or returns validation errors as JSON. -
put(Request $request, $id): updates a model or returns validation errors as JSON. -
remove($id): removes an entry by id.
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].
-
model: Name of the model (with namespace if not
App). -
--no-routes: Since routes are generated by default for the controller, this option is used to tell the generator "do not generate routes !".
-
--force: tells the generator to override the existing file.
-
--laravel: create Laravel style routes
php artisan wn:controller Task --no-routes gives:
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]
-
resource: the resource name to use in the URLs.
-
--controller: the corresponding controller. If missing it's deducted from the resource name.
-
--force: tells the generator to override the existing file.
-
--laravel: create Laravel style routes
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]
-
name: the name of the resource used in the URLs and to determine the model, table and controller names.
-
fields: specifies the fields of the resource along with schema and validation rules. It follows the syntax
name;schema;rules;tags ...-
name: the name of the field
-
schema: the schema following the syntax in the model generator. (note that the name is not part of the schema like on the model generator)
-
rules: the validation rules
-
tags: additional tags separated by commas. The possible tags are:
-
fillable: add this field to the fillable array of the model. -
date: add this field to the dates array of the model. -
key: this field is a foreign key.
-
-
-
--add: Specifies additional columns like
timestamps,softDeletes,rememberTokenandnullableTimestampsof the migration and if the list contains no timestamps, the model with containpublic $timestamps = false;. -
--has-one, --has-many and --belongs-to are the same as for the
wn:modelcommand. -
--migration-file: passed to the
wn:migrationas the--fileoption. -
--path: Defines where to store the model file as well as its namespace.
-
--force: tells the generator to override the existing file.
-
--laravel: create Laravel style routes
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:
-
--path: Defines where to store the model files as well as their namespace.
-
--laravel: create Laravel style routes
---
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.
