သတိပြုရန်

DataTable အတွက် serverSideData ထုတ်တဲ့နေရာမှာ

$departments = Department::all()->get();

ဆိုပြီးမထုတ်ရပါ။ get() က data တွေအကုန်ဆွဲထုတ်လာလို့ Database Performance ကျစေပါတယ်။ အောက်ဖော်ပြပါ အတိုင်းထုတ်ပါ။

$departments = Department::query();

HTML Tag တွေကိုဘယ်လို return ပြန်မလဲ ?

HTML Tag တွေပါရောပြီး return ပြန်မယ်ဆိုရင် rawColumns([]) ထဲမှာ register လုပ်ပေးရမယ်။

-> rawColumns(['action'])
