In Laravel, you can use the withTrashed() method to run the query and ignore soft deletion. 1. Use withTrashed() to get all records, including soft deleted records, such as User::withTrashed()->get(). 2. Use onlyTrashed() to get soft deleted records, such as User::onlyTrashed()->get(). 3. Use the restore() method to restore soft deleted records, such as User::withTrashed()->find(1)->restore(). In practical applications, the consistency of data security, performance and business logic needs to be considered.

In Laravel, how do you run a query and ignore soft delete? This problem actually touches on one of the core functions of Laravel ORM (Eloquent) - Soft Deletes. Soft deletion is a mechanism provided by Laravel that allows you to "delete" model instances without actually removing them from the database, but instead mark them as deleted by setting a deleted_at field. The advantage of this is that you can easily recover these "deleted" records when needed.

If you want to run a query and ignore soft deletion, Laravel provides an easy and elegant way to do this. Let's take a deeper look at how to do this and what points to pay attention to in practical applications.

Ignore soft deleted queries

In Laravel, you can use the withTrashed() method to include soft deleted records in the query result. This method can be applied to model query or relational query. For example, if you have a User model and you want to query all users, including those that have been soft deleted, you can do this:

 $users = User::withTrashed()->get();

This returns all user records, whether they are marked as deleted or not. If you only want to query soft deleted records, you can use onlyTrashed() method:

 $deletedUsers = User::onlyTrashed()->get();

If you want to restore a soft deleted record, you can use restore() method:

 $user = User::withTrashed()->find(1);
$user->restore();

Considerations in practical applications

In practical applications, queries that ignore soft deletes need to be handled with caution, as this may affect the consistency and security of the data. Here are some points to consider:

• Data Security : Ensure that only authorized users can access and operate soft deleted records to prevent sensitive data breaches.
• Performance : Frequent querying soft-deleted records may affect database performance, especially when there are a large number of records in your table.
• Business Logic : Make sure your business logic can handle soft deleted records correctly. For example, if you have an order system, soft deleted orders may still need to be displayed in some reports.

In-depth thinking and suggestions

Ignoring soft-deleted queries is a powerful but cautious tool. When using it, you need to consider the following points:

• Advantages : Ability to flexibly manage and recover data, improving system flexibility and fault tolerance.
• Disadvantages : It may increase system complexity, require more code to handle soft deleted records, which may affect performance.

In actual development, I suggest you:

• Clarify requirements : In the early stage of the project, clarify which models need to use soft deletion and which queries need to ignore soft deletion.
• Test : thoroughly test your query logic to ensure that no unexpected behavior is introduced when soft delete records are included.
• Documentation : Detailed documenting your soft deletion policies and query logic so that team members and future maintainers can understand and maintain these codes.

With these methods, you can effectively run queries in Laravel and ignore soft deletion while ensuring the robustness and maintainability of your application.
