Laravel model Trailing Data when save the model

Question

I have some code like this

    $editStuState = StuAtt::where(\'studentId\' , \'=\' , $id)->first();
    $editStuState -> leave +=1;
    $editStuState -         


        

Answer 1

Change your code, from:

$editStuState = StuAtt::where('studentId' , '=' , $id)->first();
$editStuState -> leave +=1;
$editStuState -> present = $editStuState -> present-1;
$editStuState->update();
                        //OR
$editStuState->save();
return 'this is good';

To:

$editStuState = StuAtt::where('studentId' , '=' , $id)->first();
$editStuState -> leave +=1;
$editStuState -> present = $editStuState -> present-1;
$editStuState->save();
return 'this is good';

Method ->update(...) is used for mass updates, check Mass Updates
