README

The PostgreSQL migration tool

Latest Stable Version Build Status Build status Coverage Status License

Requirements

  • PHP 7.4
  • PostgreSQL 9.5

Usage

Note: this is alpha software. Do not use in production (yet). I would appreciate if you could test it and provide feedback in GitHub issues. <3

Warning: never allow untrusted input in table specifications as all migrations are translated to raw SQL!

  • Add the project using composer composer install peehaa/migres
  • Run the setup ./vendor/bin/migres setup
  • Run without arguments to view the available commands ./vendor/bin/migres

All native PostgreSQL data types are implemented and the list can be found at: https://github.com/PeeHaa/migres/tree/master/src/DataType

Creating a table

<?php declare(strict_types=1);

namespace Vendor\Migrations;

use PeeHaa\Migres\DataType\BigSerial;
use PeeHaa\Migres\DataType\Boolean;
use PeeHaa\Migres\DataType\CharacterVarying;
use PeeHaa\Migres\MigrationSpecification;
use PeeHaa\Migres\Specification\Table;

class CreateTable extends MigrationSpecification
{
    public function change(): void
    {
        $this->createTable('users', function (Table $table) {
            $table->addColumn('id', new BigSerial());
            $table->addColumn('is_admin', new Boolean())->notNull()->default(false);
            $table->addColumn('name', new CharacterVarying(128))->notNull();
            $table->addColumn('email_address', new CharacterVarying(255))->notNull();
            $table->primaryKey('id');
            $table->addIndex('users_name', 'name');
            $table->addUniqueConstraint('email_address_unq', 'email_address');
        });
    }
}

Renaming a table

<?php declare(strict_types=1);

namespace Vendor\Migrations;

use PeeHaa\Migres\MigrationSpecification;

class RenameTable extends MigrationSpecification
{
    public function change(): void
    {
        $this->renameTable('users', 'members');
    }
}

Dropping a table

<?php declare(strict_types=1);

namespace Vendor\Migrations;

use PeeHaa\Migres\MigrationSpecification;

class RenameTable extends MigrationSpecification
{
    public function change(): void
    {
        $this->dropTable('members');
    }
}

Table methods

The table object defines the following methods:

Table::addColumn(string $name, \Migres\DataType\Type $dataType)

$table->addColumn('column_name', new Integer());
$table->addColumn('column_name', new Integer())->notNull;
$table->addColumn('column_name', new Integer())->default(12);

Table::dropColumn(string $name)

$table->dropColumn('column_name');

Table::renameColumn(string $oldName, string $newName)

$table->renameColumn('old_name', 'new_name');

Table::changeColumn(string $name, \Migres\DataType\Type $dataType)

$table->changeColumn('column_name', new IntegerType());
$table->changeColumn('column_name', new IntegerType())->notNull();
$table->changeColumn('column_name', new IntegerType())->default(12);

Table::primaryKey(string $column, [string ...$columns])

$table->primaryKey('column_name');
$table->primaryKey('column_name1', 'column_name2');

Table::dropPrimaryKey([string $name])

$table->dropPrimaryKey();
$table->dropPrimaryKey('table_name_pkey');

Table::namedPrimaryKey(string $name, string $column, [string ...$columns])

$table->namedPrimaryKey('custom_name_pkey', 'column_name');
$table->namedPrimaryKey('custom_name_pkey', 'column_name1', 'column_name2');

Table::renamePrimaryKey(string $oldName, string $newName)

$table->renamePrimaryKey('old_name', 'new_name');

Table::addUniqueConstraint(string $constraintName, string $column, [string ...$columns])

$table->addUniqueConstraint('constraint_name', 'column_name');
$table->addUniqueConstraint('constraint_name', 'column_name1', 'column_name2');

Table::dropUniqueConstraint(string $constraintName)

$table->dropUniqueConstraint('constraint_name');

Table::addIndex(string $indexName, string $column, [string ...$columns])

$table->addIndex('name_idx', 'column_name');
$table->addIndex('name_idx', 'column_name DESC');
$table->addIndex('name_idx', 'column_name1 DESC', 'column_name2 DESC');

Table::addBtreeIndex(string $indexName, string $column, [string ...$columns])

$table->addBtreeIndex('name_idx', 'column_name');
$table->addBtreeIndex('name_idx', 'column_name DESC');
$table->addBtreeIndex('name_idx', 'column_name1 DESC', 'column_name2 DESC');

Table::addHashIndex(string $indexName, string $column, [string ...$columns])

$table->addHashIndex('name_idx', 'column_name');
$table->addHashIndex('name_idx', 'column_name DESC');
$table->addHashIndex('name_idx', 'column_name1 DESC', 'column_name2 DESC');

Table::addGistIndex(string $indexName, string $column, [string ...$columns])

$table->addGistIndex('name_idx', 'column_name');
$table->addGistIndex('name_idx', 'column_name DESC');
$table->addGistIndex('name_idx', 'column_name1 DESC', 'column_name2 DESC');

Table::addGinIndex(string $indexName, string $column, [string ...$columns])

$table->addGinIndex('name_idx', 'column_name');
$table->addGinIndex('name_idx', 'column_name DESC');
$table->addGinIndex('name_idx', 'column_name1 DESC', 'column_name2 DESC');

Table::dropIndex(string $indexName)

$table->dropIndex('name_idx');

Table::addCheck(string $checkName, string $expression)

$table->addCheck('bigger_than_10_chk', 'column_name > 10');

Table::dropCheck(string $checkName)

$table->dropCheck('bigger_than_10_chk');
