Implementing Unique Rules Request Validation for Soft Delete in Laravel

Laravel is a robust framework that offers an array of features to help developers build dynamic web applications. One common issue developers face is ensuring that validation rules for unique constraints respect soft deletes. In this guide, we'll explore how to implement unique rules request validation for soft deletes in Laravel, specifically in the context of the AppraisalGoal model.

Understanding the Problem

In a Laravel application, when you work with soft deletes, records are not actually removed from the database; instead, a deleted_at timestamp is set. This allows for data recovery but can complicate validation rules, particularly those that involve uniqueness.

Here's the scenario: you have a form that submits data for creating or updating AppraisalGoal records. When trying to create a new record or edit an existing one, the validation checks if the goal_type_id already exists. However, even soft deleted records could trip this validation, leading to confusing error messages indicating a duplicate exists when in reality, the previous entry is merely deleted.

The Initial Validation Setup

You’ve set up your validation rules for both creating and editing records. Here’s how they currently look:

If you've successfully soft deleted records but still receive validation errors when creating new entries, you need to refine your validation rules.

Updating Validation Rules for Soft Deletes

To accurately validate for unique constraints while considering soft deletes, you should modify your validation rules, adding a check for records where the deleted_at column is NULL (indicating the record has not been soft deleted).

Revised Create Rules

Here’s how you can update the create rules:

Revised Edit Rules

For the edit rules, include a similar condition:

Conclusion

By incorporating the where('deleted_at', NULL) clause into your validation rules, you ensure that the uniqueness check for goal_type_id only applies to records that actively exist in the database. This small change significantly improves data integrity and user experience, as it prevents unnecessary validation errors for soft deleted records.

Now your Laravel application will effectively manage unique rules request validation, even with soft deletes in play, allowing you to create and edit records seamlessly.
