README

Records the changes history made to an eloquent model.

Quick start

Your model must have an id field!

composer require isaevdimka/laravel-model-changes-history

php artisan vendor:publish --tag="model-changes-history"

php artisan migrate

Note: this library use database storage as default.

Installation

composer require isaevdimka/laravel-model-changes-history

The package is auto discovered.

To change the config, publish it using the following command:

php artisan vendor:publish --provider="ModelChangesHistory\Providers\ModelChangesHistoryServiceProvider" --tag="config"

You can use three ways for record changes: 'storage' => 'database', 'file' or 'redis'

If you want to use database storage, you must publish the migration file, run the following artisan commands:

php artisan vendor:publish --provider="ModelChangesHistory\Providers\ModelChangesHistoryServiceProvider" --tag="migrations"

php artisan migrate

Use this environment to manage library:

# Global recorgin model changes history
RECORD_CHANGES_HISTORY=true

# Default storage for recorgin model changes history
MODEL_CHANGES_HISTORY_STORAGE=database

Usage

Add the trait to your model class you want to record changes history for:

use ModelChangesHistory\Traits\HasChangesHistory;
use Illuminate\Database\Eloquent\Model;

class TestModel extends Model {
    use HasChangesHistory;

    /**
     * The attributes that are mass assignable.
     * This will also be hidden for changes history.
     *
     * @var array
     */
    protected $hidden = ['password', 'remember_token'];
}

Your model now has a relation to all the changes made:

$testModel->latestChange();

ModelChangesHistory\Models\Change {
    ...
    #attributes:  [
        "model_id" => 1
        "model_type" => "App\TestModel"
        "before_changes" => "{...}"
        "after_changes" => "{...}"
        "change_type" => "updated"
        "changes" => "{
            "title": {
                "before": "Some old title",  
                "after": "This is the new title"
            },
            "body": {
                "before": "Some old body",  
                "after": "This is the new body"
            },
            "password": {
                "before": "[hidden]",  
                "after": "[hidden]"
            }
        }"
        "changer_type" =>  "App\User"
        "changer_id" => 1
        "stack_trace" => "{...}"
        "created_at" => "2020-01-21 17:34:31"
    ]
    ...
}

Getting all changes history:

$testModel->historyChanges();

Illuminate\Database\Eloquent\Collection {
  #items: array:3 [
    0 => ModelChangesHistory\Models\Change {...}
    1 => ModelChangesHistory\Models\Change {...}
    2 => ModelChangesHistory\Models\Change {...}
    ...
}

If you use database storage you can also use morph relations to Change model:

$testModel->latestChangeMorph();
$testModel->historyChangesMorph();

Clearing changes history:

$testModel->clearHistoryChanges();

Get an independent changes history:

use ModelChangesHistory\Facades\HistoryStorage;
...

$latestChanges = HistoryStorage::getHistoryChanges(); // Return collection of all latest changes
$latestChanges = HistoryStorage::getHistoryChanges($testModel); // Return collection of all latest changes for model

$latestChange = HistoryStorage::getLatestChange(); // Return latest change
$latestChange = HistoryStorage::getLatestChange($testModel); // Return latest change for model

HistoryStorage::deleteHistoryChanges(); // This will delete all history changes
HistoryStorage::deleteHistoryChanges($testModel); // This will delete all history changes for model

Getting model changer:

// Return Authenticatable `changer_type` using HasOne relation to changer_type and changer_id
$changer = $latestChange->changer; 

If you use database storage you can use Change model as:

use ModelChangesHistory\Models\Change;

// Get the updates on the given model, by the given user, in the last 30 days:
Change::query()
    ->whereModel($testModel)
    ->whereChanger($user)
    ->whereType(Change::TYPE_UPDATED)
    ->whereCreatedBetween(now()->subDays(30), now())
    ->get();

Clearing changes history using console:

php artisan changes-history:clear

You can use it in Kelner:

protected function schedule(Schedule $schedule)
{
    $schedule->command('changes-history:clear')->monthly();
}
