I have some code like this
$editStuState = StuAtt::where('studentId' , '=' , $id)->first();
$editStuState -> leave +=1;
$editStuState -> present = $editStuState -> present-1;
$editStuState->update();
//OR
$editStuState->save();
return 'this is good';
I can't save or Update my data, when I remove Update and Save related line it can print text.
this is the dd($editStuState)
data

I also got this error form laravel 5.6 it
InvalidArgumentException
Trailing data
If you are using Postgres you have to add some lines to your Model(s). It happens because of TIME WITH TIMEZONE in Postgres.
Please also read Date Mutators
as Laravel already has support for this baked in, simply put below line in your Model to override the default dateFormat for that model: https://laravel.com/docs/5.7/eloquent-mutators#date-mutators
Go to your App/Model (under app
folder, exp. User, SomeModel) add below line:
protected $dateFormat = 'Y-m-d H:i:sO';
