Extended DataTable

We can now extend and reuse our DataTable class inside our controller by using before and response callback.

IMPORTANT: Extended DataTable is only applicable on ^1.1 and above.

Upgrading from v1.0 to v1.1

Upgrade to laravel-datatables-buttons:^1.1
Rename ajax() method to dataTable()
Remove ->toJson() from the method chain.

public function ajax()
{
    return $this->datatables
        ->eloquent($this->query())
        ->addColumn('action', 'path.to.action.view')
        ->toJson()
}

public function dataTable()
{
    return $this->datatables
        ->eloquent($this->query())
        ->addColumn('action', 'path.to.action.view');
}

Quick Example:

Route::get('datatable', function(RolesDataTable $dataTable){
   return $dataTable->before(function (\Yajra\DataTables\DataTableAbstract $dataTable) {
       return $dataTable->addColumn('test', 'added inside controller');
   })
   ->response(function (\Illuminate\Support\Collection $response) {
       $response['test'] = 'Append Data';
 
       return $response;
   })
   ->withHtml(function(\Yajra\DataTables\Html\Builder $builder) {
        $builder->columns(['id', 'name', 'etc...']);
   })
   ->with('key', 'value')
   ->with([
    'key2' => 'value2',
    'key3' => 'value3',
   ])
   ->render('path.to.view');
});

Passing data to DataTable class

You can pass data from Controller to DataTable class using with api.

Route::get('datatable', function(RolesDataTable $dataTable){
   return $dataTable
       ->with('key', 'value')
       ->with([
        'key2' => 'value2',
        'key3' => 'value3',
       ])
       ->render('path.to.view');
});
