README

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:

$app->add('MigratorConsole')
    ->migrateModels([
        new Model\User($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);
$migration->table('user')
    ->id()
    ->field('name')
    ->field('address', ['type'=>'text']);
    ->create();

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

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.

Examples

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

<?php
$m = \atk4\data\schema\Migration::getMigration($connection);
$m->table('user')->drop();
$m->field('id');
$m->field('name', ['type'=>'string']);
$m->field('age', ['type'=>'integer']);
$m->field('bio');
$m->create();

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

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

// do anything with tables

$s->setDB($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'],
]];
$this->setDB($q);

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

Installation

Add the following inside your composer.json file:

composer require atk4/schema
