README

Eloquent Model Generator generates Eloquent models using database schema as a source.

Version 2.0.0

Version 2.0.0 has been released. Checkout this discussion for more details and upgrade instructions.

Installation

Step 1. Add Eloquent Model Generator to your project:

composer require krlove/eloquent-model-generator --dev

Step 2. Register GeneratorServiceProvider:

'providers' => [
    // ...
    Krlove\EloquentModelGenerator\Provider\GeneratorServiceProvider::class,
];

Step 3. Configure your database connection.

Usage

Use

php artisan krlove:generate:model User

to generate a model class. Generator will look for table named users and generate a model for it.

table-name

Use table-name option to specify another table name:

php artisan krlove:generate:model User --table-name=user

In this case generated model will contain protected $table = 'user' property.

output-path

Generated file will be saved into app/Models directory of your application and have App\Models namespace by default. If you want to change the destination and namespace, supply the output-path and namespace options respectively:

php artisan krlove:generate:model User --output-path=/full/path/to/output/directory --namespace=Your\\Custom\\Models\\Place

output-path can be absolute path or relative to project's app directory. Absolute path must start with /:

/var/www/html/app/Models - absolute path
Custom/Models - relative path, will be transformed to /var/www/html/app/Custom/Models (assuming your project app directory is /var/www/html/app)

base-class-name

By default, generated class will be extended from Illuminate\Database\Eloquent\Model. To change the base class specify base-class-name option:

php artisan krlove:generate:model User --base-class-name=Custom\\Base\\Model

no-backup

If User.php file already exist, it will be renamed into User.php~ first and saved at the same directory. Unless no-backup option is specified:

php artisan krlove:generate:model User --no-backup

Other options

There are several useful options for defining several model's properties:

no-timestamps - adds public $timestamps = false; property to the model
date-format - specifies dateFormat property of the model
connection - specifies connection name property of the model

Overriding default options

Instead of specifying options each time when executing the command you can create a config file named eloquent_model_generator.php at project's config directory with your own default values:

<?php

return [
    'namespace' => 'App',
    'base_class_name' => \Illuminate\Database\Eloquent\Model::class,
    'output_path' => null,
    'no_timestamps' => null,
    'date_format' => null,
    'connection' => null,
    'no_backup' => null,
    'db_types' => null,
];

Registering custom database types

If running a command leads to an error

[Doctrine\DBAL\DBALException]
Unknown database type <TYPE> requested, Doctrine\DBAL\Platforms\MySqlPlatform may not support it.

it means that you must register your type <TYPE> at your config/eloquent_model_generator.php:

return [
    // ...
    'db_types' => [
        '<TYPE>' => 'string',
    ],
];

Usage example

Table user:

CREATE TABLE `users` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(50) NOT NULL,
  `email` varchar(100) NOT NULL,
  `role_id` int(10) unsigned NOT NULL,
  PRIMARY KEY (`id`),
  KEY `role_id` (`role_id`),
  CONSTRAINT `user_ibfk_1` FOREIGN KEY (`role_id`) REFERENCES `roles` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8

Command:

php artisan krlove:generate:model User

Result:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

/**
 * @property int $id
 * @property int $role_id
 * @property mixed $username
 * @property mixed $email
 * @property Role $role
 * @property Article[] $articles
 * @property Comment[] $comments
 */
class User extends Model
{
    /**
     * @var array
     */
    protected $fillable = ['role_id', 'username', 'email'];

    /**
     * @return \Illuminate\Database\Eloquent\Relations\BelongsTo
     */
    public function role()
    {
        return $this->belongsTo('Role');
    }

    /**
     * @return \Illuminate\Database\Eloquent\Relations\HasMany
     */
    public function articles()
    {
        return $this->hasMany('Article');
    }

    /**
     * @return \Illuminate\Database\Eloquent\Relations\HasMany
     */
    public function comments()
    {
        return $this->hasMany('Comment');
    }
}

Generating models for all tables

Command krlove:generate:models will generate models for all tables in the database. It accepts all options available for krlove:generate:model along with skip-table option.

skip-table

Specify one or multiple table names to skip:

php artisan krlove:generate:models --skip-table=users --skip-table=roles

Note that table names must be specified without prefix if you have one configured.

Customization

You can hook into the process of model generation by adding your own instances of Krlove\EloquentModelGenerator\Processor\ProcessorInterface and tagging it with GeneratorServiceProvider::PROCESSOR_TAG.

Imagine you want to override Eloquent's perPage property value.

class PerPageProcessor implements ProcessorInterface
{
    public function process(EloquentModel $model, Config $config): void
    {
        $propertyModel = new PropertyModel('perPage', 'protected', 20);
        $dockBlockModel = new DocBlockModel('The number of models to return for pagination.', '', '@var int');
        $propertyModel->setDocBlock($dockBlockModel);
        $model->addProperty($propertyModel);
    }

    public function getPriority(): int
    {
        return 8;
    }
}

getPriority determines the order of when the processor is called relative to other processors.

In your service provider:

public function register()
{
    $this->app->tag([InflectorRulesProcessor::class], [GeneratorServiceProvider::PROCESSOR_TAG]);
}

After that, generated models will contain the following code:

/**
 * The number of models to return for pagination.
 * 
 * @var int
 */
protected $perPage = 20;
