How to Display Soft Deleted Items in Laravel Backpack

Managing soft deletes in Laravel Backpack can be challenging, especially when you want to view items that have been deleted. By default, Laravel's soft delete feature uses a global scope which prevents deleted items from appearing in your queries. However, there are straightforward ways to manipulate these scopes in different operations, particularly when you want to display deleted items in a show operation.

Understanding the Problem

When working with the Laravel Backpack package for admin panels, soft deletes are a common feature that allows you to retain deleted items in your database. This feature enables you to recover items if necessary, but it introduces some complexities:

Soft Deleted Items Not Visible: By default, soft deleted items are excluded from queries because of the global scope applied by Laravel.

Viewing Deleted Items: You might need to access and view these deleted items for various reasons, such as audits or showing revisions.

Solution Overview

To effectively display soft deleted items, you can manipulate the query scopes using Backpack’s setupListOperation() and setupShowOperation(). Below, we'll break down the steps you need to follow to accomplish this.

Adding a Filter for Soft Deleted Items

You can create a filter to allow users to choose whether they want to see soft deleted items in the list. Here’s how to do it in your setupListOperation() method:

Explanation of the Code:

addFilter Method: This method adds a filter to your CRUD list. In this case, the filter is a simple toggle labeled "Trashed".

Query Manipulation: When this filter is active, it modifies the query to retrieve only the soft deleted items using onlyTrashed().

Showing Soft Deleted Items in the Show Operation

To view deleted items within a specific show operation, you can adjust your setupShowOperation() method like this:

Key Points:

withTrashed() Method: This method allows the usual query to include soft deleted items. By applying it in the show operation, you ensure that any deleted item can be viewed when accessed directly.

Summary

By implementing the above methods, you can efficiently manage and view soft deleted items in your Laravel Backpack application. Using filters and modifying the query for show operations provides a flexible way to access and audit items that may otherwise seem lost.

Final Thoughts

Laravel’s soft delete feature, when combined with Backpack, can be a powerful tool for effective data management and user experience. This approach allows you to ensure that not only active items are visible, but also the ones that may have been deleted but are still crucial for your operations.

By following this guide, you can enhance your administrative functions, ensuring all necessary data remains accessible and manageable.
