Laravel 中的 destroy() 和 delete() 方法有什么区别?

问题描述

我在使用 Laravel 4 时遇到了一个小问题.我想对记录使用 delete() 方法，但由于某种原因它实际上并没有删除记录.destroy() 确实如此，所以我的代码很好.另外，如果我将 Teetime::where('date', '=', $formattedDate)->count() 传递给我的视图，我会得到一个正确的.有什么问题?

I'm having a minor issue with Laravel 4. I'd like to use the delete() method on a record but for some reason it doesn't actually delete the record. destroy() does, though, so my code is good. Also, if I pass Teetime::where('date', '=', $formattedDate)->count() to my view I get one which is correct. What's the problem?

        if($action=="delete") {
            $teetime = Teetime::where('date', '=', $formattedDate)->firstOrFail();
            // for some reason $teetime->delete() doesn't work
            Teetime::destroy($teetime->id);
        }

推荐答案

• destroy 是直接(通过对象或模型)删除实体的正确方法.
• destroy is correct method for removing an entity directly (via object or model).

示例:

$teetime = Teetime::where('date', '=', $formattedDate)->firstOrFail();
$teetime->destroy();

• delete 只能在查询构建器中调用
• delete can only be called in query builder

示例:

$teetime = Teetime::where('date', '=', $formattedDate)->delete();

来自文档:

User::destroy(1);

User::destroy(array(1, 2, 3));

User::destroy(1, 2, 3);

当然，您也可以对一组模型运行删除查询:

Of course, you may also run a delete query on a set of models:

$affectedRows = User::where('votes', '>', 100)->delete();
