Generate

Code Generation can be used to speed up development times by building much of the repetitive code for you. This is entirely optionally - like all of oil - and all code can be edited however you like afterwards. You can generate the following items:

Controllers

To generate a skeleton Controller with actions and views predefined, use the following command:

$ php oil g controller posts action1 action2 action3
	Created view: APPPATH/views/posts/action1.php
	Created view: APPPATH/views/posts/action2.php
	Created view: APPPATH/views/posts/action3.php
	Created controller: APPPATH/classes/controller/posts.php

This will produce a controller that looks like this:

class Controller_Posts extends Controller_Template
{

	public function action_action1()
	{
		$this->template->title = 'Posts » Action1';
		$this->template->content = View::forge('posts/action1');
	}

	public function action_action2()
	{
		$this->template->title = 'Posts » Action2';
		$this->template->content = View::forge('posts/action2');
	}

	public function action_action3()
	{
		$this->template->title = 'Posts » Action3';
		$this->template->content = View::forge('posts/action3');
	}

}

/* End of file posts.php */

Models

Generate a simple Model by listing fields and have the Migration automatically created for you to match:

$ php oil g model post title:varchar[50] body:text user_id:int
	Created model: APPPATH/classes/model/post.php
	Created migration: APPPATH/migrations/001_create_posts.php

That will create a simple Model that uses Orm, so make sure the package is enabled in your config file. It will look like this:

class Model_Post extends Orm\Model {

	protected static $_properties = array(
		'id',
		'title',
		'body',
		'created_at',
		'updated_at'
	);

	protected static $_observers = array(
		'Orm\Observer_CreatedAt' => array(
			'events' => array('before_insert'),
			'mysql_timestamp' => false,
		),
		'Orm\Observer_UpdatedAt' => array(
			'events' => array('before_save'),
			'mysql_timestamp' => false,
		),
	);

}

/* End of file post.php */

Not very exciting, but the migration is the useful part here:

namespace Fuel\Migrations;

class Create_posts
{
	public function up()
	{
		\DBUtil::create_table('posts', array(
			'id' => array('constraint' => 11, 'type' => 'int', 'auto_increment' => true),
			'title' => array('constraint' => 50, 'type' => 'varchar'),
			'body' => array('type' => 'text'),
			'user_id' => array('constraint' => 11, 'type' => 'int'),
			'created_at' => array('type' => 'datetime'),

		), array('id'));
	}

	public function down()
	{
		\DBUtil::drop_table('posts');
	}
}

If you do not wish to generate a migration, simply supply the --no-migration:

$ php oil g model post title:varchar[50] body:text user_id:int --no-migration
	Created model: APPPATH/classes/model/post.php

Generating Model using Model_Crud

FuelPHP v1.1 added a simple Model_Crud base model which offers similar functionality of using ORM without overhead of relational data. You can have the model generated using this by adding --crud

$ php oil g model post title:varchar[50] body:text user_id:int created_at:datetime --crud
	Created model: APPPATH/classes/model/post.php
	Created migration: APPPATH/migrations/001_create_posts.php

That will create a simple Model that uses Fuel\Core\Model_Crud. It will look like this:

class Model_Post extends \Model_Crud
{
	protected static $_properties = array(
		'id',
		'title',
		'body',
		'user_id',
		'created_at',
		'updated_at'
	);

	protected static $_table_name = 'posts';

}

Generating Model Without Timestamp Option

Add --no-timestamp to exclude the created/updated fields and observers.

$ php oil g model post title:varchar[50] body:text user_id:int --no-timestamp
class Model_Post extends \Orm\Model
{
  protected static $_properties = array(
    'id',
    'title',
    'body',
    'user_id'
  );

}
namespace Fuel\Migrations;

class Create_posts
{
  public function up()
  {
    \DBUtil::create_table('posts', array(
      'id' => array('constraint' => 11, 'type' => 'int', 'auto_increment' => true),
      'title' => array('constraint' => 50, 'type' => 'varchar'),
      'body' => array('type' => 'text'),
      'user_id' => array('constraint' => 11, 'type' => 'int'),

    ), array('id'));
  }

  public function down()
  {
    \DBUtil::drop_table('posts');
  }
}

Changing Timestamp Fields

When you're using the timestamp fields in either ORM models or CRUD models (\Model_Crud) you can chose your own field names. Use the --created-at and --updated-at options to set your own field names.

$ php oil g model post title:varchar[50] body:text user_id:int --created-at=my_created

Which will give you:

<?php

class Model_Post extends \Orm\Model
{
	protected static $_properties = array(
		'id',
		'title',
		'body',
		'user_id',
		'my_created',
		'updated_at'
	);

	protected static $_observers = array(
		'Orm\Observer_CreatedAt' => array(
			'events' => array('before_insert'),
			'mysql_timestamp' => false,
			'property' => 'my_created',
		),
		'Orm\Observer_UpdatedAt' => array(
			'events' => array('before_save'),
			'mysql_timestamp' => false,
		),
	);
}
<?php

namespace Fuel\Migrations;

class Create_posts
{
	public function up()
	{
		\DBUtil::create_table('posts', array(
			'id' => array('constraint' => 11, 'type' => 'int', 'auto_increment' => true),
			'title' => array('constraint' => 50, 'type' => 'varchar'),
			'body' => array('type' => 'text'),
			'user_id' => array('constraint' => 11, 'type' => 'int'),
			'my_created' => array('constraint' => 11, 'type' => 'int'),
			'updated_at' => array('constraint' => 11, 'type' => 'int'),

		), array('id'));
	}

	public function down()
	{
		\DBUtil::drop_table('posts');
	}
}

Viewmodels

Optionally you have have oil to generate a Viewmodel class to accompany the view.

$ php oil g controller posts action1 action2 action3 --with-viewmodel

Running Migrations

The following commands illustrate how to use the refine command to run useful migration tasks, assuming that the system is currently at migration 5. The migrate task can be given parameters to move directly to a given version, or just up/down by a single version.

$ php oil refine migrate
	Currently on migration: 5.

$ php oil refine migrate --version=4
	Migrated to version: 4.

$ php oil refine migrate --version=5
	Migrated to version: 5.

$ php oil refine migrate:down
	Migrated to version: 4.

$ php oil refine migrate:up
	Migrated to version: 5.

The following field types are supported: string[n], varchar[n], int[n], enum[value1, value2], decimal[n, n], float[n, n], text, blob, datetime, date, timestamp and time.

Generating Migrations

You can generate migrations without creating a model. This could be used to rename a table, or add fields to a table in a way that is easy to deploy in other environments.

$ php oil generate migration rename_table_users_to_accounts
	Building magic migration: rename_table
	Created migration: APPPATH/migrations/002_rename_table_users_to_accounts.php

Magic Migrations

There are a number of "magic" migrations which automatically build you a migration based on a prefix to your migration name.

$ php oil generate migration create_users name:text email:string[50] password:string[125]
$ php oil generate migration rename_table_users_to_accounts
$ php oil generate migration add_bio_to_accounts bio:text
$ php oil generate migration delete_bio_from_accounts bio:text
$ php oil generate migration rename_field_name_to_username_in_accounts
$ php oil generate migration drop_accounts

Note: Be careful when naming your migrations that you don't begin with any keywords by accident.

Scaffolding

Scaffolding is the really exciting part of Oil's code generation. This approach is heavily borrowed from Rails who have done a great job with it. The idea is that you create not only the MVC skeletons and migrations, but populate them with default CRUD code so the code will actually work after writing the command.

$ php oil g scaffold monkey name:string description:text
	Created model: APPPATH/classes/model/monkey.php
	Created migration: APPPATH/migrations/003_create_monkeys.php
	Created controller: APPPATH/classes/controller/monkeys.php
	Created view: APPPATH/views/monkeys/index.php
	Created view: APPPATH/views/monkeys/view.php
	Created view: APPPATH/views/monkeys/create.php
	Created view: APPPATH/views/monkeys/edit.php
	Created view: APPPATH/views/monkeys/_form.php

$ php oil refine migrate
Migrated to latest version: 3.

As you can see lots of code is generated by this command including a command that is executed in the second command. The controller looks like this:

class Controller_Monkey extends Controller_Template
{

	public function action_index()
	{
		$data['monkeys'] = Model_Monkey::find('all');
		$this->template->title = "Monkeys";
		$this->template->content = View::forge('monkey/index', $data);

	}

	public function action_view($id = null)
	{
		$data['monkey'] = Model_Monkey::find($id);

		$this->template->title = "Monkey";
		$this->template->content = View::forge('monkey/view', $data);

	}

	public function action_create($id = null)
	{
		if (Input::method() == 'POST')
		{
			$monkey = Model_Monkey::forge(array(
				'name' => Input::post('name'),
				'description' => Input::post('description'),
			));

			if ($monkey and $monkey->save())
			{
				Session::set_flash('success', 'Added monkey #'.$monkey->id.'.');

				Response::redirect('monkey');
			}

			else
			{
				Session::set_flash('error', 'Could not save monkey.');
			}
		}

		$this->template->title = "Monkeys";
		$this->template->content = View::forge('monkey/create');

	}

	public function action_edit($id = null)
	{
		$monkey = Model_Monkey::find($id);

		if (Input::method() == 'POST')
		{
			$monkey->name = Input::post('name');
			$monkey->description = Input::post('description');

			if ($monkey->save())
			{
				Session::set_flash('success', 'Updated monkey #' . $id);

				Response::redirect('monkey');
			}

			else
			{
				Session::set_flash('error', 'Could not update monkey #' . $id);
			}
		}

		else
		{
			$this->template->set_global('monkey', $monkey, false);
		}

		$this->template->title = "Monkeys";
		$this->template->content = View::forge('monkey/edit');

	}

	public function action_delete($id = null)
	{
		if ($monkey = Model_Monkey::find($id))
		{
			$monkey->delete();

			Session::set_flash('success', 'Deleted monkey #'.$id);
		}

		else
		{
			Session::set_flash('error', 'Could not delete monkey #'.$id);
		}

		Response::redirect('monkey');

	}


}

Tasks

You can also have oil generate the skeleton of a new task.

$ php oil g task newtask cmd1 cmd2

Which will generate

<?php

namespace Fuel\Tasks;

class Newtask
{
	public static function run($args = NULL)
	{
		echo "\n===========================================";
		echo "\nRunning DEFAULT task [Newtask:Run]";
		echo "\n-------------------------------------------\n\n";

		/***************************
		 Put in TASK DETAILS HERE
		 **************************/
	}

	public static function cmd1($args = NULL)
	{
		echo "\n===========================================";
		echo "\nRunning task [Newtask:Cmd1]";
		echo "\n-------------------------------------------\n\n";

		/***************************
		 Put in TASK DETAILS HERE
		 **************************/
	}

	public static function cmd2($args = NULL)
	{
		echo "\n===========================================";
		echo "\nRunning task [Newtask:Cmd2]";
		echo "\n-------------------------------------------\n\n";

		/***************************
		 Put in TASK DETAILS HERE
		 **************************/
	}
}
/* End of file tasks/newtask.php */

Configs

To generate a Config, use the following command:

$ php oil g config sample hello:world
	Created config: APPPATH/config/sample.php

This will produce a config that looks like this:

return array (
	'hello' => 'world',
);

/* End of file sample.php */

Generate Config from COREPATH

To combine config from COREPATH/config if APPPATH/config doesn't have one

$ php oil g config package
	Created config: APPPATH/config/package.php

This will produce a config that looks like this:

return array (
	'sources' =>
	array (
		0 => 'github.com/fuel-packages',
	),
);

Force Update Config from COREPATH & APPPATH

To combine config from COREPATH/config and combine APPPATH/config to APPPATH/config

$ php oil g config form --overwrite
	Created config: APPPATH/config/form.php

This will produce a config that looks like this:

return array (
	'prep_value' => true,
	'auto_id' => true,
	'auto_id_prefix' => '',
	'form_method' => 'post',
);

/* End of file form.php */
