Restoring Soft Deleted Files in Laravel 8

Managing files and database records efficiently is crucial in any web application. If you're using Laravel, you might be familiar with soft deletes, a powerful feature that allows you to "delete" a record without permanently removing it from the database. However, things can get a bit tricky when it comes to handling files associated with these records. In this post, we will explore the common issue of restoring soft-deleted files in Laravel 8 and provide a comprehensive approach to solving it.

The Issue at Hand

Imagine you've implemented soft deletes in your Laravel model, and you want to delete a submission and its associated uploaded files. Once the record is soft deleted, you realize you need to restore that file back to its original location. Typically, when you soft delete a record, it is marked in the database, but files are permanently deleted when you manually delete them from the storage or public folder—meaning, you can't simply restore the file like you would a database entry.

Here's a snippet from a Laravel delete method for context:

The challenge lies in how to restore the file once it has been deleted from the storage.

Understanding Soft Deletes

What are Soft Deletes?

Soft deletes in Laravel make use of the SoftDeletes trait, which allows you to keep records in the database while marking them as deleted. Instead of removing a record, Laravel adds a deleted_at timestamp to indicate when it was deleted. This allows you to easily restore records later.

Limitations with Files

It is important to note that soft deletes apply only to database records, not to physical files stored on your server. When you delete a file, it is removed from the file system instantly, meaning there is no built-in method to recover it later through Laravel's soft delete functionality.

A Practical Solution for Restoring Files

Move Files to a Separate Directory

To simulate a soft delete for files, you can create a mechanism that moves the files to a temporary 'deleted' folder instead of deleting them outright. This way, you can restore the files when needed. Here’s a step-by-step approach to implement this:

Create a Deleted Folder: In your public or storage directory, create a folder called deleted_files (or a name of your choice) to temporarily hold deleted files.

Modify the Delete Method: Instead of deleting the file in the delete method, update your existing logic to move the file to the newly created folder. Here’s how you can modify your existing code:

Implement the Restore Function: Create a function to restore files from the deleted folder back to their original location:

Conclusion

While Laravel's soft delete feature is helpful for managing database records, it doesn't extend to physical files on your server. By creatively moving files to a designated folder instead of deleting them, you can simulate soft deletes for files, allowing for easy restoration when needed. Following the steps outlined above will help you effectively manage soft-deleted files in Laravel 8, ensuring you never lose important data permanently.

Implementing these improvements not only enhances your application's data management capabilities but also provides a safety net for user-uploaded files, reducing the likelihood of critical data loss.
