MigBuilder reverse engineer from MySQL to Eloquent Laravels ORM

 

MigBuilder is a tool to reverse engineer a MySQL database into Models, Factories, Seeders & Migrations files for Laravel Eloquent ORM.

It reads the database structure and completes as much code as possible to ease the model generation in Laravel.

Unless the model is structured exactly as expected, the code files will contain non accurate lines or declarations. So it is ALWAYS recommended to check the code once is generated.

The ‘perfect’ tables definition is:

  • Tables should contain a single column primary key, better if its name is ‘id’
  • Relationships have to be declared and always be composed of one single column
  • Not frequent datatypes (binary, longtext, …) have not been tested yet
INSTALLATION

composer require pangodream/migbuilder

USAGE

php artisan migbuilder originschema

Migbuilder will read originschema database (originschema is the connection name in Laravel config/app.php file) and will generate the migration, model, seeder and factory files for each of the tables A good practice is two have two different connections declared in Laravel config/database.php file:

  • One alternative connection pointing to the existing database to be reverse engineered
  • The main connection that will be used to deploy migrate files and use models in

CAUTION: If you use the command above and any of the generated files already exists, the generation will not begin unless you specify the overwrite (–overwrite) parameter. Notice that using overwrite will destroy the information you have in any of your files having the same name.

NOTE: Migbuilder is not an error free code generator, but a help to save hand code lines, so you should review the generated code in every case.

I hope it to help you and if you have any comment, please let me know.
