How to Fix a 404 Error When Restoring Soft Deleted Data in Laravel

If you're working with Laravel and utilizing the soft delete feature, you might have encountered a frustrating issue: being unable to restore soft deleted data. Instead of successfully restoring the data, you face a pesky 404 error. This article will explore the common reasons for this issue and provide a step-by-step guide to resolving it.

Understanding Soft Deletes in Laravel

Before we dive into the solution, let’s briefly recap how soft deletes function in Laravel. Soft deleting a model means that the data is not permanently removed from the database but is marked as deleted. This allows you to recover (or restore) the data later if needed.

Laravel utilizes a deleted_at column to mark records as soft deleted. When you want to restore a soft deleted record, you'll typically use the restore() method.

The Problem: 404 Error During Restoration

You’ve set up your code for soft deletes, and everything seems in place until you try to restore a deleted record. Instead of success, you’re met with a 404 Not Found error. The culprit often lies in how Laravel retrieves the model that you wish to restore.

The Code You Have

You have implemented the following method to restore a course:

But this method relies on dependency injection to retrieve the course based on the id from the URL. The issue arises because the course you're trying to access has already been marked as deleted, which prevents it from being fetched using route model binding.

The Solution: Refactor Your Restore Method

To resolve this issue, you’ll need to change your method so that it takes the course ID directly instead of relying on the model binding feature. Here’s how to refactor your method:

Key Changes Explained

Parameter Change: Instead of having dependency injection for the Course model, the method now accepts a simple course ID parameter.

Direct Retrieval: The method uses onlyTrashed()->find() to locate the soft deleted record directly by its ID.

Updating the Route

Make sure your routing definition aligns with the updated restore method. Your current route setup should look like this:

Note: The parameter {course} in the route will correspond to the course ID that will be passed to your restored method.

Implementing the Restore Button

When incorporating a restore button in your frontend, ensure it links with the correct ID:

Final Thoughts

Soft deletes are powerful features in Laravel that enhance data integrity. However, understanding how to properly implement restoration of soft deleted data is essential to avoid errors like 404. By following the steps laid out in this guide, you should be able to correct the functionality and restore your deleted data seamlessly.
