#Installation

1. Create a Laravel project and configure Filament on this project

laravel new MyProject

Refer to Filament documentation: https://filamentphp.com/docs/2.x/admin/installation#installation

2. Install the package

composer require heloufir/filament-workflow-manager

3. Register the package into your application providers config/app.php

\Heloufir\FilamentWorkflowManager\FilamentWorkflowManagerServiceProvider::class,

4. Run migrations

php artisan migrate

5. Create a new Filament user (refer to the Filament documentation) https://filamentphp.com/docs/2.x/admin/installation#installation

6. Serve your project

php artisan serve

Here you can see a menu named Workflows under Settings menu group, it's where you can manage your workflows.

#Configuration

1. Create your model

php artisan make:model MyModel

2. Configure your model to implement Workflow manager

use Heloufir\FilamentWorkflowManager\Core\HasWorkflow;
use Heloufir\FilamentWorkflowManager\Core\InteractsWithWorkflows;
// ...
 
class MyModel extends Model implements HasWorkflow
{
    use InteractsWithWorkflows;
 
    // ...
}

Here you need to add the implementation of the interface InteractsWithWorkflows and add the use of the trait InteractsWithWorkflows to your model.

3. Create a workflow

After you have configured your model, you can now create a workflow linked to this model, watch the following demo video:

4. Add a Filament resource to manage your model

Refer to the Filament documentation: https://filamentphp.com/docs/2.x/admin/resources/getting-started#creating-a-resource

5. Configure the Filament resource

• In your form Filament resource declaration you need to add WorkflowStatusInput::make() so your users can change the status of YourModel depending on your workflow configuration:

use Heloufir\FilamentWorkflowManager\Forms\Components\WorkflowStatusInput;
 
public static function form(Form $form): Form
{
    return $form
        ->schema([
            // ...
 
            WorkflowStatusInput::make()
        ]);
}

• If you wan't to show the model current status in the Filament resource table, you need to add the WorkflowStatusColumn::make() column definition:

use Heloufir\FilamentWorkflowManager\Tables\Columns\WorkflowStatusColumn;
 
public static function table(Table $table): Table
{
    return $table
        ->columns([
            // ...
 
            WorkflowStatusColumn::make()
        ]);
}

The last configuration needed, is to add WorkflowResource trait to the EditRecord and CreateRecord components of your model

EditRecord component

// ...
use Heloufir\FilamentWorkflowManager\Core\WorkflowResource;
 
class EditMyModel extends EditRecord
{
    use WorkflowResource;
 
    // ...
}

CreateRecord component

// ...
use Heloufir\FilamentWorkflowManager\Core\WorkflowResource;
 
class CreateMyModel extends CreateRecord
{
    use WorkflowResource;
 
    // ...
}

#History system

From the version 1.1.3 of this package, the history system is now available, and you can use it as below:

Important: Automatically the package will create an history row in the database after all status update of your models

To show the history inside your Filament resource table you only need to add workflow_resources_history() function call in your table's actions:

// ...
->actions([
    // ...
 
    workflow_resources_history()
])
// ...

This helper function will show a link action History.

When the user clicks on this link, a new tab will open and will display a table containing the history of all status changes.

#Events handler

From the version 1.1.4 of this package, on each status update the event WorkflowStatusUpdated is fired with a details object.

#Details object definition

#Details object example

{
  "type": "update",
  "old_status": {
    "id": 1,
    "name": "Created",
    "color": "#f4f6f7",
    "is_end": 0,
    "created_at": "2022-07-05T13:56:50.000000Z",
    "updated_at": "2022-07-05T13:56:50.000000Z",
    "deleted_at": null
  },
  "new_status": {
    "id": 2,
    "name": "Submitted",
    "color": "#bacef7",
    "is_end": 0,
    "created_at": "2022-07-05T13:56:50.000000Z",
    "updated_at": "2022-07-05T13:56:50.000000Z",
    "deleted_at": null
  },
  "model": {
    "id": 3,
    "name": "My model name",
    "created_at": "2022-07-05T14:23:33.000000Z",
    "updated_at": "2022-07-05T14:23:33.000000Z",
    "workflow_status_id": 1,
    "workflow_status": {
      "id": 3,
      "modelable_type": "App\\Models\\MyModel",
      "modelable_id": 3,
      "workflow_status_id": "2",
      "created_at": "2022-07-05T14:23:33.000000Z",
      "updated_at": "2022-07-05T14:23:36.000000Z",
      "status": {
        "id": 2,
        "name": "Submitted",
        "color": "#bacef7",
        "created_at": "2022-07-05T13:56:50.000000Z",
        "updated_at": "2022-07-05T13:56:50.000000Z",
        "deleted_at": null
      }
    }
  },
  "user": {
    "id": 1,
    "name": "EL OUFIR Hatim",
    "email": "[email protected]",
    "email_verified_at": null,
    "created_at": "2022-07-05T13:43:57.000000Z",
    "updated_at": "2022-07-05T13:43:57.000000Z"
  }
}

#Usage example

So to listen to this event you can define a function like below:

<?php
 
namespace App\Filament\Resources\MyModelResource\Pages;
 
use Heloufir\FilamentWorkflowManager\Core\WorkflowResource;
use App\Filament\Resources\MyModelResource;
use Filament\Resources\Pages\EditRecord;
 
class EditMyModel extends EditRecord
{
    use WorkflowResource;
 
    protected $listeners = ['WorkflowStatusUpdated' => 'status_updated'];
 
    protected static string $resource = MyModelResource::class;
 
    public function status_updated($obj)
    {
        dd($obj); // $obj is the details object defined before
    }
}

#End of workflow

From the version 1.1.6 of this package, you can add an end flag to a workflow status to detect if it's the end of the workflow.

Important: You cannot add a transition after another transition based on a to status flagged as end of workflow.

#Permissions

From the version 1.1.8 of this package, you can manage workflow permissions of your users.

#Configuration

To configure your User model to use workflow permissions, you need to use the WorkflowPermissions trait:

use Heloufir\FilamentWorkflowManager\Core\WorkflowPermissions;
use Illuminate\Foundation\Auth\User as Authenticatable;
 
class User extends Authenticatable
{
    use WorkflowPermissions;
 
    // ...
}

After that, in you Filament user resource, you need to add the WorkflowPermissions relation:

use Heloufir\FilamentWorkflowManager\Resources\UserResource\WorkflowPermissions;
 
public static function getRelations(): array
{
    return [
        WorkflowPermissions::class,
    ];
}

#Usage example

In the workflow manage page you can create multiple access level to your workflow transitions, as below:

After you have created your workflow permissions, you can attach them to your users:
