Laravel 5, log Model create, update , delete events

Question

I am developing Laravel 5 app. In Which I want to log Model create, update and deleted event with all New or changed(in case Model is being updated) Model Fields . I want simple reusable solution without writing too much of a code.

Answer 1

Although old thread, but with specific reference to OP's request of simple reusable solution without writing too much of a code, Spatie's activity logger is a breeze! This specific part of their full documentation shows how simply and easy OP's quest can be!

Answer 2

I've made a little modification hope It helps. ( this just keeps track of modification on the model )

migration

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;

class CreateLogActions extends Migration
{
  /**
   * Run the migrations.
   *
   * @return void
   */
  public function up()
  {
    Schema::create('log_actions', function (Blueprint $table) {
      $table->increments('id');
      $table->integer('loggable_id');
      $table->string('loggable_type');
      $table->string('action');
      $table->integer('user_id')->unsigned()->index();
      $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
      $table->timestamp('dt_action');
    });
  }

  /**
   * Reverse the migrations.
   *
   * @return void
   */
  public function down()
  {
    Schema::drop('log_actions');
  }
}

model

<?php

namespace App\Wdog\Entities;

use Illuminate\Database\Eloquent\Model;
use Prettus\Repository\Contracts\Transformable;
use Prettus\Repository\Traits\TransformableTrait;

class LogAction extends Model implements Transformable
{
  use TransformableTrait;

  protected $fillable = [
    'loggable_type',
    'loggable_id',
    'user_id',
    'action',
    'dt_action'

  ];

  public $timestamps = false;

  protected $dates = [
    'dt_action'
  ];

  public function user()
  {
    return $this->belongsTo('App\User');
  }

  public function loggable()
  {
    return $this->morphTo();
  }
}

Trait

finally just add a trait

<?php   

namespace App\Wdog\Traits;

use App\Wdog\Entities\LogAction;
use Auth;
use Carbon\Carbon;
use Illuminate\Database\Eloquent\Model;


trait ModelEventLogger
{

  public static function bootModelEventLogger()
  {

    $user_id = Auth::user()->id;
    foreach (static::getRecordActivityEvents() as $eventName) {


      static::$eventName(function (Model $model) use ($user_id, $eventName) {

        $log = new LogAction([
          'user_id'   => $user_id,
          'dt_action' => Carbon::now(),
          'action'     => $eventName
        ]);          

        $model->logs()->save($log);


      });
    }    
  }    

  protected static function getRecordActivityEvents()
  {
    if (isset(static::$recordEvents)) {
      return static::$recordEvents;
    }

    return [
      'created',
      'updated',
      'deleted',
    ];
  }


  protected static function logs()
  {


    return $this->morphMany('\App\Wdog\Entities\LogAction', 'loggable')->orderBy('dt_action', 'desc');




  }


}

then just use the trait in your model

class User extends Model implements Transformable
{
  use ModelEventLogger;
...

Answer 3

Sure you can create trait like below and use it in all models you want to log.,

<?php

namespace App\Traits;

use App\Activity;
use Illuminate\Database\Eloquent\Model;

/**
 * Class ModelEventLogger
 * @package App\Traits
 *
 *  Automatically Log Add, Update, Delete events of Model.
 */
trait ModelEventLogger {

    /**
     * Automatically boot with Model, and register Events handler.
     */
    protected static function bootModelEventLogger()
    {
        foreach (static::getRecordActivityEvents() as $eventName) {
            static::$eventName(function (Model $model) use ($eventName) {
                try {
                    $reflect = new \ReflectionClass($model);
                    return Activity::create([
                        'user_id'     => \Auth::user()->id,
                        'contentId'   => $model->id,
                        'contentType' => get_class($model),
                        'action'      => static::getActionName($eventName),
                        'description' => ucfirst($eventName) . " a " . $reflect->getShortName(),
                        'details'     => json_encode($model->getDirty())
                    ]);
                } catch (\Exception $e) {
                    return true;
                }
            });
        }
    }

    /**
     * Set the default events to be recorded if the $recordEvents
     * property does not exist on the model.
     *
     * @return array
     */
    protected static function getRecordActivityEvents()
    {
        if (isset(static::$recordEvents)) {
            return static::$recordEvents;
        }

        return [
            'created',
            'updated',
            'deleted',
        ];
    }

    /**
     * Return Suitable action name for Supplied Event
     *
     * @param $event
     * @return string
     */
    protected static function getActionName($event)
    {
        switch (strtolower($event)) {
            case 'created':
                return 'create';
                break;
            case 'updated':
                return 'update';
                break;
            case 'deleted':
                return 'delete';
                break;
            default:
                return 'unknown';
        }
    }
} 

Now you can use this trait in any Model you want to throw events for. In your case in Article Model.

<?php namespace App;

use App\Traits\ModelEventLogger;
use Illuminate\Database\Eloquent\Model;

class Test extends Model {

    use ModelEventLogger;

    //Just in case you want specific events to be fired for Article model
    //uncomment following line of code

   // protected static $recordEvents = ['created'];

}

Ofcourse you will have to create 'Activity' model and related table with relevent columns. I hope this helps.
