Generate Laravel Migrations from an existing database, including indexes and foreign keys!
This package is cloned from https://github.com/Xethron/migrations-generator and updated to support Laravel 5.6 and above, with more features.
Laravel Migrations Generator supports all five Laravel first-party support databases:
- MariaDB
- MySQL
- PostgreSQL
- SQL Server
- SQLite
Laravel | Version |

9.x | 6.x |
8.x | 6.x |
7.x | 6.x |
6.x | 6.x |
5.8.x | 6.x |
5.7.x | 6.x |

5.5 and below | https://github.com/Xethron/migrations-generator |
The recommended way to install this is through composer:
composer require --dev "kitloong/laravel-migrations-generator"
Laravel will automatically register service provider for you.
Auto-discovery is not available in Lumen, you need some modification on bootstrap/app.php
.
Uncomment the following line.
$app->withFacades();
Add following line into the Register Service Providers
section.
$app->register(\KitLoong\MigrationsGenerator\MigrationsGeneratorServiceProvider::class);
To generate migrations from a database, you need to have your database setup in Laravel's config (config/database.php
).
To create migrations for all the tables, run:
php artisan migrate:generate
You can specify the tables you wish to generate using:
php artisan migrate:generate --tables="table1,table2,table3,table4,table5"
You can also ignore tables with:
php artisan migrate:generate --ignore="table3,table4,table5"
Laravel Migrations Generator will first generate all the tables, columns and indexes, and afterwards setup all the foreign key constraints.
So make sure you include all the tables listed in the foreign keys so that they are present when the foreign keys are created.
You can also specify the connection name if you are not using your default connection with:
php artisan migrate:generate --connection="connection_name"
By default, Generator will generate multiple migration files for each table.
You can squash all migrations into a single file with:
php artisan migrate:generate --squash
Run php artisan help migrate:generate
for a list of options.
Options | Description |
---|---|
-c, --connection[=CONNECTION] | The database connection to use |
-t, --tables[=TABLES] | A list of Tables or Views you wish to Generate Migrations for separated by a comma: users,posts,comments |
-i, --ignore[=IGNORE] | A list of Tables or Views you wish to ignore, separated by a comma: users,posts,comments |
-p, --path[=PATH] | Where should the file be created? |
-tp, --template-path[=TEMPLATE-PATH] | The location of the template for this generator |
--date[=DATE] | Migrations will be created with specified date. Views and Foreign keys will be created with + 1 second. Date should be in format supported by Carbon::parse |
--table-filename[=TABLE-FILENAME] | Define table migration filename, default pattern: [datetime_prefix]\_create_[table]_table.php |
--view-filename[=VIEW-FILENAME] | Define view migration filename, default pattern: [datetime_prefix]\_create_[table]_view.php |
--fk-filename[=FK-FILENAME] | Define foreign key migration filename, default pattern: [datetime_prefix]\_add_foreign_keys_to_[table]_table.php |
--default-index-names | Don't use DB index names for migrations |
--default-fk-names | Don't use DB foreign key names for migrations |
--use-db-collation | Generate migrations with existing DB collation |
--skip-views | Don't generate views |
--squash | Generate all migrations into a single file |
The generator first generates all tables and then adds foreign keys to existing tables.
However, SQLite only supports foreign keys upon creation of the table and not when tables are altered. add_foreign_keys migrations will still be generated, however will get omitted if migrate to SQLite type database.
The generator will register custom data type from pg_type
, then generate migration as
public function up()
{
Schema::create('table', function (Blueprint $table) {
...
});
DB::statement("ALTER TABLE table ADD column custom_type NOT NULL");
}
Note that the new column
is always added at the end of the created table
which means the ordering of the column generated in migration will differ from what we have from the schema.
