Laravel 专家！请帮帮我。
我是 laravel 的新手，刚刚使用 yajra 数据表制作了数据表。 问题是当结果超过2k行时它的速度太慢了。
请检查我的代码，并为我提供修复它的最佳解决方案。
请注意，我是初学者，请原谅我的纯编码。
我没有使用 get() 进行收集，也许 Join 和 WhereIn 子句有问题？
控制器：
public function MyController(Request $request)
{
if(request()->ajax())
{
$season_id_array = $request -> season_id_array;
$season_id_array = explode(",", $season_id_array);
$league_id_array = $request -> league_id_array;
$league_id_array = explode(",", $league_id_array);
$weeknumber_date = $request -> weeknumber;
$match_result = DB::table('season_match_plan as a')
->join('team_list as b', 'b.team_id', '=', 'a.home_team_id')
->join('team_list as c', 'c.team_id', '=', 'a.away_team_id')
->join('season as d', 'd.season_id', '=', 'a.season_id')
->join('league as e', 'e.league_id', '=', 'a.league_id')

->leftJoin('odds as h2',
function($join)

$join->on('a.match_id', '=','h2.match_id');
$join->on('h2.bookmaker_id', '=', DB::raw('(SELECT id FROM bookmakers WHERE bookmaker_name = "highest")'));
}
)
->leftjoin('real_price_dcl as r', 'a.DCL_refer_id', '=', 'r.id')

})
-> select(

return DataTables()::of($match_result)
->editColumn('Score', function($match_result) {
return html_entity_decode($match_result->Score);
})
->rawColumns(['Score'])
->make(true);
}
}
JS：
$('#table').DataTable({
processing: false,
lengthMenu: [[10, 50, 100, -1], [ 10,50, 100, "All"]],
pageLength: 100,
destroy: true,
serverSide: true,
ajax: {
url: "showRanking",
type: 'POST',
data:
{
_token : $('meta[name="csrf-token"]').attr('content'),
season_id_array : season_id_array,
league_id_array : league_id_array,
weeknumber : weeknumber,
}
},
columns: [
{ data: 'League', name: 'League', width: '200px' },
{ data: 'Season', name: 'Season' },
{ data: 'Date', name: 'a.Date' },
{ data: 'c_WN', name: 'c_WN' },
{ data: 'Game', name: 'Game', width:'200px'},
{ data: 'Score', name: 'Score' },
{ data: 'Home_team_name', name: 'Home_team_name'},
{ data: 'Static_HRank', name: 'Static_HRank' },
{ data: 'Dynamic_HRS_8', name: 'Dynamic_HRS_8'},
{ data: 'Dynamic_HRS_6', name: 'Dynamic_HRS_6'},
{ data: 'Home_score', name: 'Home_score'},
{ data: 'Home_strength', name: 'Home_strength'},
{ data: 'Away_team_name', name: 'Away_team_name'},
{ data: 'Static_ARank', name: 'Static_ARank' },
{ data: 'Dynamic_ARS_8', name: 'Dynamic_ARS_8'},
{ data: 'Dynamic_ARS_6', name: 'Dynamic_ARS_6'},
{ data: 'Away_score', name: 'Away_score'},
{ data: 'Away_strength', name: 'Away_strength'},
{ data: 'staticRank', name: 'staticRank'},
{ data: 'DynamicRank_8', name: 'DynamicRank_8'},
{ data: 'DynamicRank_6', name: 'DynamicRank_6'},
{ data: 'highest_Home', name: 'highest_Home'},
{ data: 'highest_Draw', name: 'highest_Draw'},
{ data: 'highest_Away', name: 'highest_Away'},
{ data: 'Real_Home', name: 'Real_Home'},
{ data: 'Real_Draw', name: 'Real_Draw'},
{ data: 'Real_Away', name: 'Real_Away'},
],
}
);
因此排序和搜索在 Front 上也不起作用。
请帮助我，我是 Laravel 初学者。
此致。
