First,I call artisan tinker using the command below
$ php artisan tinker
Then, I plan to get all of the model in Admin to update the name as "admin", then I save the update by using command below
$admin = App\Admin::get()->name="admin"->save()
//Admin is my model
//name is the table structure of Admin table
//then I save it with save()
However, it pop out an error as shown below :-
PHP Error: Call to a member function save() on string in Psy Shell code on line 1
