Laravel 共享主机 ajax 删除
Laravel Shared hosting ajax delete
出于测试目的,我在免费托管上托管了我的网站,一切正常,但 Ajax 删除了。当我点击删除时,删除功能运行并且所有内容都被删除,但由于某种原因它 returns 500 错误。在本地它可以正常工作。
Route::delete('/admin/deleteRound', 'AdminCyclesController@deleteRound')->name('admin.deleteRound');
和
$.ajax({
type: "POST",
url: urlDeleteRound,
data: {cycle_id: cycle_id, round: round, _token: token, _method: 'delete'}
}).success(function (response) {.....});
我尝试了所有可以在网上找到的方法,但都没有成功。有没有办法解决这个问题,或者至少有办法找出问题所在?
已编辑 - .log
我不知道该怎么做。

编辑 2 - 执行删除的代码
public function deleteRound(Request $request){
$round=$request['round'];
$id=$request['cycle_id'];
DB::select("DELETE FROM `cycle_team` where cycle_team.cycle_id=$id and cycle_team.round=$round");
$teams = DB::select("SELECT teams.id, teams.title,sum(ct.points) + sum(ct.is_winner) + sum(ct.is_over) as points, sum(ct.points) + sum(ct.is_winner) + sum(ct.is_over)-Min(ct.points + ct.is_winner + ct.is_over) as minpoints, COUNT(teams.id)-1 as number FROM `teams`INNER JOIN cycle_team as ct on teams.id =ct.team_id INNER JOIN cycles as c on c.id = ct.cycle_id where ct.cycle_id =$id > 0 GROUP BY ct.cycle_id, ct.team_id, teams.title, teams.id order by points desc");
return response()->json(['teams'=>$teams]);
}
解决方案
DB::select("DELETE FROM `cycle_team` where cycle_team.cycle_id=$id and cycle_team.round=$round")
一直在制造问题,使用 Builder 解决了问题
DB::table('cycle_team')->where('cycle_id', id)->where('round', $round)->delete();
您正在使用 DB::select()
,它在后台默认使用 只读 PDO 实例。由于 DELETE
是写入操作,因此出现一般错误。
考虑使用 DB::delete()
方法而不是 DB::select()
,因为这是您正在执行的操作类型。
您也可以使用 DB::statement()
,其中 returns 是一个基于查询是否成功的布尔值,或者 DB::affectingStatement()
如果您想要查询影响的行数.
或者,按照评论中的建议,使用查询构建器构建删除查询。
DB::table('cycle_team')
->where('cycle_id', $id)
->where('round', $round)
->delete();
