Laravel-datatables: Wrong id column value

Created on 9 Dec 2016 · 3Comments · Source: yajra/laravel-datatables

Summary of problem or feature request

Values of the id column are wrong when the id isn't requested from the javascript side.

The problem only appears only when i don't mention the id column in the dataTables setting columns.

$('#table').DataTable({
    columns: [
            { data: 'id', name: 'id' }, // ----> Problem appear when i don't mention this column in javascript
            { data: 'user.first_name', name: 'user.first_name' },
            ...
    ]
})

In the PHP side i have something like this

$students = Student::with(['user', ...]);

return Datatables::of($students)
->addColumn('actions', function ($row)
{
    $row->id // ----> Will contain wrong value, it will contain users.id instead of students.id

    return $actions;
})
->make(true);

The value of id will be users.id instead of students.id

System details

PHP Version : 5.6

I think this is a bug in the laravel framework and the work around to fix this is by adding select('students.*') on your query as documented here.

$students = Student::with(['user', ...])->select('students.*');

return Datatables::of($students)
->addColumn('actions', function ($row)
{
    $row->id // ----> Will contain wrong value, it will contain users.id instead of students.id

    return $actions;
})
->make(true);

@yajra, your answer helped me, thanks. It would be better is you remove the comment as in your example it should be the opposite. It will contain the correct value.
Thanks
