Php 从数据库中删除与具有laravel的其他表关联的行

我的数据库中有4个表

mail_tasks => MailTask (class)
mail_messages => MailMessage (class)
meos => Meo (class)
mail_recipients => MailRecipient (class)

我需要删除该列表中包含“deleted_at”的非空值的前3个表中的所有行，换句话说，使用forceDelete删除行（该行以前使用softdelete删除）

问题是，我需要首先删除每个表与不同表之间的关联

MailTask is associated with Meos table
Meos is associated with MailRecipient

邮件任务迁移和关联

    $table->foreign('meo_id')->references('id')->on('meos')->onDelete('cascade');

    $table->foreign('meo_id')->references('id')->on('meos')->onDelete('cascade');

邮件收件人迁移和关联

    $table->foreign('meo_id')->references('id')->on('meos')->onDelete('cascade');

    $table->foreign('meo_id')->references('id')->on('meos')->onDelete('cascade');

MEO迁移和关联

    $table->foreign('location_id')->references('id')->on('locations')->onDelete('cascade');
    $table->foreign('business_type_id')->references('id')->on('business_types')->onDelete('cascade');

public function handle()
{
   $mailMessage = MailMessage::query()->whereNotNull('deleted_at');
   $mailMessage->forceDelete();
   $mailTask = MailTask::query()->whereNotNull('deleted_at');
   $mailTask->forceDelete();
   $meo = Meo::query()->whereNotNull('deleted_at');
   $meo->forceDelete();
}

我需要删除“deleted_all”不为空的邮件

我需要删除MailTask，其中“deleted_all”不为null，并删除与Meo的第一个关联

我需要删除“deleted_all”不为空的Meo，并删除与邮件收件人的第一个关联

我有这个，但我不明白如何删除关联

    $table->foreign('location_id')->references('id')->on('locations')->onDelete('cascade');
    $table->foreign('business_type_id')->references('id')->on('business_types')->onDelete('cascade');

public function handle()
{
   $mailMessage = MailMessage::query()->whereNotNull('deleted_at');
   $mailMessage->forceDelete();
   $mailTask = MailTask::query()->whereNotNull('deleted_at');
   $mailTask->forceDelete();
   $meo = Meo::query()->whereNotNull('deleted_at');
   $meo->forceDelete();
}

我这样做没关系吧？还是我需要做更多的事情
