Laravel-datatables: How to send parameters to DataTable Service UsersDataTable Class?

If you are using v7, you can use:

class UsersController extends Controller
{
    public function index(UsersDataTable $dataTable)
    {
        return $dataTable->with('key', 'value')->render('users');
    }
}

And access it like a property on dataTable class.

public function query() {
  $key = $this->key;
  ...
}

This is the commit where I added this functionality in case you need. Not yet added on documentation.

hi, thank you for the reply, I am currently using 6.x for Laravel 5.3.30,

will it work if I copy and paste the commit code into datatables 6.x?

I added the commit code to the Datatables 6.x package, it is working nicely just that in the DataTable Service class query():

    public function query()
    {

        $id = $this->id;

        $restaurant = restaurant::where('res_id', $id);

        return $this->applyScopes($restaurant);

    }

the return $this->applyScopes($restaurant); , $restaurant is showing a warning:

Expected \Illuminate\Database\Eloquent\Builder|\Illuminate\Database\Query\Builder, got \App\Models\restaurant less... (Ctrl+F1) 
Invocation parameter types are not compatible with declared.

but If I add the ->get() like, return $this->applyScopes($restaurant->get()); the warning will be gone, but the datatable View will get error like:

DataTables warning: table id=dataTableBuilder - ajax error.

Can you paste your restaurant class? I think there is something wrong with your model.

Anyways, it is not advisable to edit the vendor folder so I decided to add the fluent variables on v6 too.

Please update to v6.27.0 to have this feature. Thanks!

Hey yajra, It's $key = $this->attributes; not $key = $this->key; Right?
I used this $key = $this->attributes;

@jcduenasr the class uses a magic getter method which fetches the values from keys in the attributes.

Hi, I have two date fields in a form to filter the table query by dates and prevent it from bringing me thousands of records.
The problem is that when I try to export with one of the buttons, the query is not sending the date filters, so I'm not bringing anything.
How do I send the date fields using the buttons to export?

This is my class.
namespace AppDataTables;
use App\Accesos;
use YajraDatatables\Services\DataTable;

class AccesosDataTable extends DataTable
{

public function ajax()
{   

    return $this->datatables
    ->eloquent($this->query())
    ->make(true);

}


public function html()
{
    return $this->builder()
                ->columns($this->getColumns())
                    ->ajax('')
                ->parameters([
                    'dom'          => 'Bfrtip',  
                    'buttons'      => ['export', 'reload'],
                ]);
}

public function query()
{
    $key = $this->attributes;
    $users = Accesos::whereBetween('field_filter',[$key['from'].' 00:00:00',$key['to'].' 23:59:59'])->select();

    return $this->applyScopes($users);

}

protected function getColumns()
{
    return [
        'field1',
        'field2',
        'field3',
        'field4',
        'field5',
        'field6',
    ];
}

    protected function filename()
    {
         return strtolower(trans('accesos'));
    }

}
