Mako Schema Builder

This is a simple database schema builder package for Mako Framework >=4.5.

This package runs on top of Phinx

Install

Use composer to install. Simply add package to your project.

composer require softr/mako-schema-builder:*

So now you can update your project with a single command.

composer update

Register Service

After installing you'll have to register the package in your app/config/application.php file.

'packages' =>
[
    ...
    'web' =>
    [
        ...
        // Register the package for web app
        'softr\MakoSchemaBuilder\SchemaPackage',
    ],
    'cli' =>
    [
        ...
        // Register the package for command line app
        'softr\MakoSchemaBuilder\SchemaPackage',
    ]
],

Creating Tables

To create a new database table, use the create method. The create method accepts two arguments. The first is the name of the table, while the second is a Closure which receives a object used to define the new table:

$this->schema->create('users', function($table)
{
    $table
        ->addColumn('username', 'string', ['limit' => 20])
        ->addColumn('password', 'string', ['limit' => 40])
        ->addColumn('password_salt', 'string', ['limit' => 40])
        ->addColumn('email', 'string', ['limit' => 100])
        ->addIndex(['username', 'email'], ['unique' => true]);
});

Modifying Tables

To modify an existing table, use the table method. The table method accepts two arguments. The first is the name of the table, while the second is a Closure which receives a object used to define the table wich will be modified:

$this->schema->table('users', function($table)
{
    $table->addColumn('username', 'string', ['limit' => 20])
          ->changeColumn('email', 'string', ['limit' => 255]);
});

Connection

You can also specify an alternative connection. Just use the connection method specifing the connection name.

$this->schema->connection('foo')->create('table', function($table)
{
    ....
});

Renaming / Dropping Tables

To rename an existing database table, use the renameTable method:

$this->schema->renameTable('from', 'to');

To drop an existing table, you may use the dropTable or dropIfExists methods:

$this->schema->dropTable('users');

$this->schema->dropIfExists('users');

Checking For Table / Column Existence

You may easily check for the existence of a table or column using the hasTable, hasColumn and hasColumns methods:

if($this->schema->hasTable('users'))
{
    // Do something
}

if($this->schema->hasColumn('users', 'email'))
{
    // Do something
}

if($this->schema->hasColumns('users', ['name', 'email']))
{
    // Only returns true if all fields exists on table
}

Working With Columns

Get a column list

To retrieve all table columns, simply call the getTableColumns method. This method will return an array of column names.

$columns = $this->schema->getTableColumns('users');

Renaming a Column

To rename a column access an instance of the Table object then call the renameColumn method.

$table->renameColumn('bio', 'biography');

Adding a Column After Another Column

When adding a column you can dictate its position using the after option.

$table->addColumn('city', 'string', ['after' => 'email']);

Dropping a Column

To drop a column, use the removeColumn method.

$table->removeColumn('short_name');

Specifying a Column Limit

You can limit the maximum length of a column by using the limit option.

$table->addColumn('short_name', 'string', ['limit' => 30]);

Changing Column Attributes

To change column type or options on an existing column, use the changeColumn method.

$table->changeColumn('email', 'string', ['limit' => 255]);

Working with Indexes

To add an index to a table you can simply call the addIndex() method on the table object.

$table->addIndex(['email']);

We can pass an additional parameter to the addIndex() method to specify a unique index.

$table->addIndex(['email'], ['unique' => true]);

Removing indexes is as easy as calling the removeIndex() method. You must call this method for each index.

$table->removeIndex(['email']);

Working With Foreign Keys

Phinx has support for creating foreign key constraints on your database tables. Let’s add a foreign key to an example table:

$this->schema->create('tags', function($table)
{
    $table->addColumn('tag_name', 'string')
});

$this->schema->create('tag_relationships', function($table)
{
    $table->addColumn('tag_id', 'integer')
          ->addForeignKey('tag_id', 'tags', 'id', ['delete'=> 'SET_NULL', 'update'=> 'NO_ACTION']);
});

It is also possible to pass addForeignKey an array of columns. This allows us to establish a foreign key relationship to a table which uses a combined key.

$this->schema->table('follower_events', function($table)
{
    $table->addColumn('user_id', 'integer')
          ->addColumn('follower_id', 'integer')
          ->addColumn('event_id', 'integer')
          ->addForeignKey(['user_id', 'follower_id'], 'followers', ['user_id', 'follower_id'], ['delete'=> 'NO_ACTION', 'update'=> 'NO_ACTION']);
});

We can also easily check if a foreign key exists:

$this->schema->table('tag_relationships', function($table)
{
    if($table->hasForeignKey('tag_id'))
    {
        // do something
    }
});

Finally to delete a foreign key use the dropForeignKey method.

$this->schema->table('tag_relationships', function($table)
{
    $table->dropForeignKey('tag_id');
});
