Agile Schema

2.0.0 2019-12-02 03:10 UTC


This extension for Agile Data implements ability to work with SQL schema, execute migrations, perform DB-tests in PHPUnit (used by other ATK frameworks) and sync up "Model" structure to the database.

Basic Usage:

// Add the following code on your setup page / wizard:

        new Model\User($app->db), 
        new Model\Order($app->db),
        new Model\Payment($app->db)

The user will see a console which would adjust database to contain required tables / fields for the models:


Of course it's also possible to perform migration without visual feedback:

$changes = (\atk4\schema\Migration::getMigration(new User($app->db)))->migrate();

If you need a more fine-graned migration, you can define them in great detail.

// create table
$migration = \atk4\schema\Migration::getMigration($app->db);
    ->field('address', ['type'=>'text']);

// or alter
$migration = \atk4\schema\Migration::getMigration($app->db);
    ->newField('age', ['type'=>'integer'])

Currently we fully support MySQL and SQLite connections, partly PgSQL and Oracle connections. Other SQL databases are not yet supported. Field declaration uses same types as ATK Data.


schema\Migration is a simple class for building schema-related queries using DSQL.

$m = \atk4\data\schema\Migration::getMigration($connection);
$m->field('name', ['type'=>'string']);
$m->field('age', ['type'=>'integer']);

schema\Snapshot (NOT IMPLEMENTED) is a simple class that can record and restore table contents:

$s = new \atk4\data\schema\Snapshot($connection);
$tables = $s->getDB($tables);

// do anything with tables


Integration with PHPUnit

You can now automate your database testing by setting and checking your database contents easier. First, extend your test-script from \atk4\schema\PHPUnit_SchemaTestCase.

Next, you need to set your schema

$q = ['user' => [
    ['name' => 'John', 'surname' => 'Smith'],
    ['name' => 'Steve', 'surname' => 'Jobs'],

Perform any changes, then execute:

$this->assertEquals($q, $this->getDB('user'));

To ensure that database remained the same. Of course you can compare against any other state.

  • Automatically add 'id' field by default
  • Create tables for you
  • Detect types (int, string, date, boolean etc)
  • Hides ID values if you don't pass them


Add the following inside your composer.json file:

composer require atk4/schema
