Understanding Soft Delete in Laravel: How to Properly Hide Deleted Records in View

When working with Laravel, one of the key features you may want to implement is the soft delete functionality using Eloquent. However, some developers encounter issues where deleted records are still visible in their views, even after marking them as deleted. This guide will help you understand why that happens and how to solve the issue effectively.

What is Soft Delete?

In Laravel, soft delete allows you to retain records in your database while effectively marking them as deleted. Instead of permanently removing a record, Laravel uses a timestamp column (usually named deleted_at) to indicate that an entry is no longer active. This is beneficial because you can restore deleted records if necessary.

The Problem: Records Not Hiding

You may be experiencing a situation where you've implemented soft deletes but find that deleted records are not being hidden from your views. The common scenario is illustrated by the following code in your controller:

In this code, you are joining the roles and users tables. However, the soft delete functionality is tied to the User model, and it doesn’t apply automatically when you join tables.

Solution: Utilize Eloquent's Capabilities

To ensure that you only display non-deleted users in your list, you need to modify your query slightly. Here’s how you can do it effectively:

Filtering Out Deleted Records

Add a condition to your query to filter out users who are marked as deleted:

This addition ensures that only users who have deleted_at set to null (i.e., not deleted) are included in your paginated results.

Simplifying Your Query with Relationships

You might also want to consider leveraging Eloquent relationships to simplify your query. Instead of manually joining tables, you can use Eloquent's relationship functions to accomplish the same goal:

This will fetch all roles and include users that belong to them, automatically filtering out the soft-deleted users based on the relationship definition.

Iterating Over Roles and Users

Once you have your roles with their respective users, you can display them as follows:

Updating Relationship Definitions

Make sure your relationship definitions explicitly define the foreign key when they do not match the default Laravel naming conventions. Here’s how to do this properly:

Conclusion

Implementing soft delete in Laravel can sometimes lead to confusion, especially when viewing combined records from multiple tables. By adjusting your queries to respect soft delete functionality and proper use of Eloquent relationships, you can effectively manage the visibility of your records.

Take the time to understand how these core concepts work, and you will find that your Laravel applications become more robust and easier to maintain. If you have any questions or further issues, feel free to reach out or comment below!
