Laravel Eloquent Delete Child Table Row - 在 Delete('cascade') 上没有删除子表行

Question

提前谢谢你

我有 2 个如下表

1) users
2) reviews

我创建的架构如下所示

    Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('first_name',100)->nullable();
            $table->timestamps();
    });
   Schema::create('reviews', function (Blueprint $table) {
            $table->id();
            $table->bigInteger('user_id')->unsigned();
            $table->string('name',100)->nullable();
            $table->timestamps();
            $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    });

• 当我删除用户时，它不是删除属于已删除用户的评论

• 我正在像下面这样删除用户

  用户::where('id',1)->delete();

  是否有任何简短、简单和完美的方法来为所有雄辩的模型做这些？

Answer 1

您可以在父模型中尝试此代码：

public static function boot()
  {
    parent::boot();

    static::deleting(function ($model) {
      $model->relations()->delete();
    });
  }

*softDeletes 更新

public static function boot()
{
  parent::boot();

  static::deleting(function ($model) {
  if($model->isForceDeleting()){
      $model->relations()->delete();//or forceDelete if child also using softDelete
    });
  }
}
