The simpleWorkflow extension is a set of Yii components that is dedicated to provide an easy way to manage the life cycle of CActiveRecord objects inside a workflow. It provides features to control the behavior of the active record in its associated workflow : transition tasks, status constraints, event model.

Resources

Documentation

Requirements

Yii 1.1.4 or above

Installation

Extract the released files under protected/extensions.
add the SWPhpWorkflowSource component to your configuration

```php 'components'=>array( // adding the simple Workflow source component 'swSource'=> array( 'class'=>'application.extensions.simpleWorkflow.SWPhpWorkflowSource', ), ...

```

add simpleWorkflow extension base folder to your imports

```php 'import'=>array( ... 'application.extensions.simpleWorkflow.*', // Import simpleWorkflow extension ), ```

Usage

Once installed and correctly configured, the simpleWorkflow extension will handle the workflow for any model. To enable simpleWorkflow for a given model, you must attach the SWActiveRecordBehavior behavior to this model.

```php class MyModel extends CActiveRecord { public function behaviors() { return array( 'swBehavior' => array( 'class' => 'application.extensions.simpleWorkflow.SWActiveRecordBehavior' ) ); } } ```

The model can then be inserted into a workflow, and evolve among statuses inside this workflow. For instance, the code below insert an existing record into a workflow, or if already done, displays its current status :

```php $m=MyModel::model()->findByPk('1'); if( $m->swHasStatus() ){ echo 'status : '.$m->swGetStatus()->toString(); }else { $m->swInsertToWorkflow(); $m->save(); } ```

Gii Command

Creating a workflow 'by hand' can become an error-prone task when several nodes and edges are required. One good option is to create the workflow using a visual tools, and after some searches it seems that one of the best application to do it is yEd Graph Editor. Of course, it is free to use !

Once created and saved to graphml format, the workflow can be converted into a simpleworkflow, ready to use. To learn more about the simpleWorkflow Gii command, please check the command folder.
