Eloquent Model Generator

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

Version 1.0.0

Version 1.0.0 has been released.

Installation

Step 1. Configure your database connection. Run your migrations.

Step 2. Add Eloquent Model Generator to your project:

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

Usage

Use

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

no-timestamps

If you want to disable timestamps for the model, specify --no-timestamps option:

php artisan ray:generate:model User --no-timestamps

date-format

If you want to specify date format for the model, specify --date-format option:

php artisan ray:generate:model User --date-format='Y-m-d'

connection

If you want to specify connection name for the model, specify --connection option:

php artisan ray:generate:model User --connection='mysql'

Overriding default options

Instead of specifying options each time when executing the command you can publish the config file by executing the following command:

php artisan vendor:publish --provider="Ray\EloquentModelGenerator\Provider\GeneratorServiceProvider"

This will create a file named eloquent_model_generator.php at project's config directory. You can modify the file 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,
    `role_id`  int(10) unsigned NOT NULL,
    `username` varchar(50)      NOT NULL,
    `email`    varchar(100)     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 ray:generate:model User

Result:

App\Models\User.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

/**
 * @property integer $id
 * @property integer $role_id
 * @property string $username
 * @property string $email
 * @property Role $role
 */
class User extends Model
{
    /**
     * @var array
     */
    protected $fillable = ['role_id', 'username', 'email'];

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

Generating models for all tables

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

skip-table

Specify one or multiple table names to skip:

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

OR specify a string of tables separated by a comma:

php artisan ray:generate:models --skip-table="users,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 Ray\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);
        
        $propertyModel = new PropertyModel('guarded', 'protected', []);
        $dockBlockModel = new DocBlockModel('¡Tengo miedo!.', '@var array');
        $propertyModel->setDocBlock($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([PerPageProcessor::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;

/**
 * ¡Tengo miedo!.
 * 
 * @var array
 */
protected $guarded = [];
...

Notes:

Processor priority is important. Priority 0 is the highest priority. The higher the priority, the later the processor is called.

Default processor priority:

• TableNameProcessor - 0
• ClassDefinitionProcessor - 18
• NamespaceProcessor - 1
• BaseClassProcessor - 2
• CustomPrimaryKeyProcessor - 3
• SoftDeleteTraitProcessor - 4
• DateFormatProcessor - 5
• ConnectionProcessor - 6
• NoBackupProcessor - 7
• PropertyProcessor - 8
• RelationProcessor - 9
• DocBlockProcessor - 10
• FillableProcessor - 11
• PrimaryKeyProcessor - 12
• TimestampsProcessor - 13
• TableNameProcessor - 14
• BackupProcessor - 15
• ModelProcessor - 16
• UseStatementProcessor - 17
• NamespaceDirectoryProcessor - 19
