What is the difference between destroy() and delete() methods in Laravel?
提问by phoops
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?
我在 Laravel 4 中遇到了一个小问题。我想delete()
在记录上使用该方法,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,如果我传递Teetime::where('date', '=', $formattedDate)->count()
给我的观点,我会得到一个正确的观点。有什么问题?
if($action=="delete") {
$teetime = Teetime::where('date', '=', $formattedDate)->firstOrFail();
// for some reason $teetime->delete() doesn't work
Teetime::destroy($teetime->id);
}

destroy
is correct method for removing an entity directly (via object or model).
destroy
是直接(通过对象或模型)删除实体的正确方法。
Example:
例子:
$teetime = Teetime::where('date', '=', $formattedDate)->firstOrFail();
$teetime->destroy();
delete
can only be called in query builder
delete
只能在查询构建器中调用
Example:
例子:
$teetime = Teetime::where('date', '=', $formattedDate)->delete();
From documentation:
从文档:
Deleting An Existing Model By Key
通过键删除现有模型
User::destroy(1);
User::destroy(array(1, 2, 3));
User::destroy(1, 2, 3);
Of course, you may also run a delete query on a set of models:
当然,您也可以对一组模型运行删除查询:
$affectedRows = User::where('votes', '>', 100)->delete();
