There are a few ways to handle this situation while still using soft deletes on the users table. One option is to add a unique constraint to the email or username column, so that even if a user is soft deleted, their email or username cannot be used again for a new account. Another option is to add a "deleted_at" column to the unique constraint, so that the constraint only applies to non-deleted users.
Here's an example of how to add a unique constraint with a "deleted_at" column in a Laravel migration:
Schema::table('users', function (Blueprint $table) {
$table->unique(['email', 'deleted_at']);
});
This will ensure that no two non-deleted users can have the same email address, but a deleted user's email address can be used again for a new account.
Alternatively, you could also consider using a "soft delete cascade" to delete related records when a user is soft deleted. For example, if a user has associated records in a "posts" table, you could set up a cascade so that when the user is soft deleted, all of their posts are also soft deleted. This would prevent the issue of a deleted user's email or username being used again for a new account.
Here's an example of how to set up a soft delete cascade in a Laravel migration:
Schema::table('posts', function (Blueprint $table) {
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
});
This will ensure that when a user is soft deleted, all of their associated posts will also be soft deleted.
Ultimately, whether or not to use soft deletes on the users table depends on your specific use case and requirements. If you need to be able to reuse email or username credentials, then soft deletes may not be the best option. However, if you want to be able to restore deleted users or keep a record of when users were deleted, then soft deletes can be a useful feature.
