README
Library to dynamically handle workflows in a database with ROA support.
Getting Started
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
Prerequisites
- Install PHP 7.2 or higher
- Composer Installed
The rest of the requirements are checked by composer when installing the repository on the next step.
Installation
You can use composer to install the library roaresearch/yii2-workflow
by running
the command;
composer require roaresearch/yii2-workflow
or edit the composer.json
file
require: { "roaresearch/yii2-workflow": "*", }
Deployment
Then run the required migrations
php yii migrate/up -p=@roaresearch/workflow/migrations
Which will install the following table structure
ROA Backend Usage
The ROA support is very simple and can be done by just adding a module version to the api container which will be used to hold the resources.
class Api extends \roaresearch\yii2\roa\modules\ApiContainer { public $versions = [ // other versions 'w1' => ['class' => 'roaresearch\yii2\workflow\roa\modules\Version'], ]; }
You can then access the module to check the available resources.
- workflow
- workflow/<workflow_id:\d+>/stage
- workflow/<workflow_id:\d+>/stage/<stage_id:\d+>/transition
- workflow/<workflow_id:\d+>/stage/<stage_id:\d+>/transition/<target_id:\d+>/permission
Which will implement CRUD functionalities for a workflow.
Process and Worklog
A process
is an entity which changes from stage depending on a workflow. Each
stage change is registered on a worklog
for each process
record.
To create a process
its required to create a migrations for the process and
the worklog then the models to handle them, its adviced to use the provided
migration templates.
class m170101_010101_credit extends EntityTable { public function getTableName(): string { return 'credit'; } public function columns(): array { return [ 'id' => $this->primaryKey(), 'workflow_id' => $this->normalKey(), // other columns ]; } public function foreignKeys(): array { return [ 'workflow_id' => ['table' => 'workflow']; ]; } }
class m170101_010102_credit_worklog extends \roaresearch\yii2\workflow\migrations\WorkLog { public function getProcessTableName(): string { return 'credit'; } }
After running the migrations its necessary to create Active Record models.
class Credit extends \roaresearch\yii2\workflow\models\Process { protected function workflowClass(): string { return CreditWorkLog::class; } public function getWorkflowId(): int { return $this->workflow_id; } public function rules() { return \yii\helpers\ArrayHelper::merge(parent::rules(), [ // other rules here ]); } }
class CreditWorkLog extends \roaresearch\yii2\workflow\models\WorkLog { public static function processClass(): string { return Credit::class; } }
Initial Worklog
Notice that by default every new record of Process being validated will attempt
to create an initial WorkLog. If you want to prevent this behavior for example
on search models you need to set the Process::$autogenerateInitialWorklog
to
false
class CrediSearch extends \roaresearch\yii2\workflow\models\WorkLog { /** * @inhertidoc */ protected $autogenerateInitialWorklog = false; }
If this option is set to true
then on the same request which creates the
process Credit
can receive fields comment
and stage_id
which will be
stored not in the process Credit
but in the worklog record.
Relations Process::$worklogs
and Process::$activeWorkLog
Process models contain 2 relations to handle its work log. $workLogs
provide
the list of all the related work logs and $activeWorkLog
find only the most
recent worklog using the groupwise search strategy.
Notice that the groupwise strategy implies a join query with aliased tables, as such extra consideration is needed when joining with other queries.
Worklog Resource
Each process gets a worklog about the flow of stages it goes through.
On ROA you can declare each worklog as a child resource for the process resource
public $resources = [ 'credit', 'credit/<credit_id:\d+>/worklog' => [ 'class' => WorklogResource::class, 'modelClass' => CreditWorkLog::class, ] ];
[Detailed documentation for worklog and its use cases](Worklog.md]
Running the tests
This library contains tools to set up a testing environment using composer scripts, for more information see Testing Environment section.
Break down into end to end tests
Once testing environment is setup, run the following commands.
composer deploy-tests
Run tests.
composer run-tests
Run tests with coverage.
composer run-coverage
Live Demo
You can run a live demo on a freshly installed project to help you run testing or understand the responses returned by the server. The live demo is initialized with the command.
php -S localhost:8000 -t tests/_app
Where :8000
is the port number which can be changed. This allows you call ROA
services on a browser or REST client.
