Eloquent Restore with restoring soft deleted models

TL;DR When using Eloquent's soft delete feature in Laravel, you can restore deleted models by calling the restore() method on the affected instance, which resets the deleted_at column to NULL. This effectively un-hides the record and makes it visible again in your database.

Eloquent Restore: Restoring Soft Deleted Models in Laravel

As a developer, you're likely familiar with the concept of soft deletes in Eloquent, Laravel's ORM system. But have you ever needed to restore a soft deleted model? Perhaps your user accidentally deleted an important record and needs it back? Or maybe you've implemented a delete functionality that also keeps track of deleted records for auditing purposes.

Whatever the reason, restoring soft deleted models is a crucial aspect of database management in Laravel. In this article, we'll dive into the world of Eloquent restore, exploring how to properly restore soft deleted models and what's happening behind the scenes.

Understanding Soft Deletes

Before we begin, let's quickly recap how soft deletes work in Eloquent. When you use the delete() method on a model, it doesn't actually remove the record from your database. Instead, it updates a few columns to mark the record as deleted:

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    protected $softDelete = true;
}

In this example, any time you call delete() on an instance of the User model, Eloquent will update the deleted_at column with the current timestamp. This effectively "hides" the record from view, making it seem like it's been deleted.

Restoring Soft Deleted Models

Now that we've covered soft deletes, let's talk about restoring them. To restore a soft deleted model, you can use the restore() method on the affected instance:

$user = User::where('name', 'John')->first();
$user->delete(); // Mark as deleted

// Later...
$user->restore(); // Restore to its original state

When you call restore(), Eloquent will simply reset the deleted_at column back to NULL. This effectively "unhides" the record, making it visible again in your database.

Behind the Scenes: What's Happening with restore()

So what's happening behind the scenes when you call restore()? Let's take a peek at the code:

public function restore()
{
    if (! $this->hasBeenSoftDeleted()) {
        return;
    }

    // Reset deleted_at column to NULL
    $this->update(['deleted_at' => null]);
}

As you can see, restore() checks whether the model has been marked as soft deleted using the hasBeenSoftDeleted() method. If it hasn't, nothing happens.

Next, it simply updates the deleted_at column to NULL, effectively restoring the record to its original state.

Conclusion

In this article, we've explored the concept of Eloquent restore and how to properly restore soft deleted models in Laravel. Whether you're implementing a delete functionality or need to recover accidentally deleted records, understanding the ins and outs of restore() is crucial for any developer working with Eloquent.

Remember: when it comes to database management, it's essential to know what's happening behind the scenes. With this knowledge, you'll be well-equipped to handle even the most complex data restoration scenarios in Laravel.
