问题描述

我在Laravel 4中遇到一个小问题。我想在记录上使用 delete()方法,但由于某种原因,它并不实际删除记录。 destroy()尽管如此,我的代码是好的。此外,如果我通过 Teetime :: where('date','=',$ formattedDate) - > count()给我的看法,我得到一个是正确的。有什么问题?

  if($ action ==delete){
$ teetime = Teetime :: where ('date','=',$ formattedDate) - > firstOrFail();
//由于某种原因$ teetime-> delete()不起作用
Teetime :: destroy($ teetime-> id);
}


解决方案


  • destroy 是直接(通过对象或模型)删除实体的正确方法。



示例:

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




  • 删除只能在查询构建器中调用



示例:

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

从文档中:



删除现有模型按键



  User :: destroy(1); 

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

用户:: destroy(1,2,3);

当然,您也可以在一组模型上运行删除查询:

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

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);
        }
解决方案

  • destroy is correct method for removing an entity directly (via object or model).

Example:

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

  • delete can only be called in query builder

Example:

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

From documentation:

Deleting An Existing Model By Key

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:

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