Exclude columns when exporting

[dhcmega]

Summary of problem or feature request

Problem: Export is too slow
Reason?: I think the problem is that the action column is processed for each line
If I skip the action column (in my case with 20k records) export speed is many times faster.

Code snippet of problem

        return $dataTable->addColumn('action', 'admin.users.datatables_actions');

Actual work around

        if($this->request()->filled('action')) {
            return $dataTable;
        }
        return $dataTable->addColumn('action', 'admin.users.datatables_actions');

I found this using strace
There was one of this chunks per row (user in this case).
This a simplified part of the strace output:

access("storage/framework/views/c08be0011b8c2177fd317340650742011c1b1208.php", F_OK) = 0
stat("resources/views/admin/users/datatables_actions.blade.php", {}) = 0
stat("storage/framework/views/c08be0011b8c2177fd317340650742011c1b1208.php", {}) = 0
lstat("resources/views/admin/users/datatables_actions.blade.php", {}) = 0
lstat("resources/views/admin/users", {}) = 0
lstat("resources/views/admin", {}) = 0
lstat("resources/views", {}) = 0
lstat("resources", {}) = 0

Even though the column is not exported, it's being processed.
I hope I got right and I am not confused about this.

Thanks!

Are you using the DataTable service class? If yes, you can override $exportColumns property and exclude the action column.

protected $exportColumns = [];

See https://yajrabox.com/docs/laravel-datatables/master/export-column for ref.

Hi, thanks for responding, I will check it.

Btw, you can also use ->exportable(false) on you column definitions:

Column::computed('action')->exportable(false)->printable(false);

exportable(false) not works

I had the same issue and fixed it by including vendor/datatables/buttons.server-side.js in html
