如何添加选择下拉过滤器

Question

问题或功能请求摘要

我正在尝试添加 3 个过滤器（状态、发件人、收件人）。我如何使用

Yajra\DataTables\Services\DataTable

类来做到这一点？

            ->minifiedAjax()
            ->dom('Brtip')

    }

    /**
     * Get columns.
     *
     * @return array
     */
    protected function getColumns()
    {
        return [
            Column::make('Order #'),
            Column::make('Gifted Account'),
            Column::make('Bank Name'),
            Column::make('Status'),
            // Column::make('Actions')
        ];
    }

    /**
     * Get filename for export.
     *
     * @return string
     */
    protected function filename()
    {
        return 'bank_transfer_payments_report_' . date('YmdHis');
    }
}

还有风景：

{{ $dataTable->scripts() }}

<script>
    $(function () {
        const filter = () => {
            const filters = {
                filters: {
                    status: $('#filterStatus').val()
                }
            };

            // window.LaravelDataTables["bankTransferPaymentsTable"].destroy();

            window.LaravelDataTables["bankTransferPaymentsTable"].search(JSON.stringify(filters)).draw();
                
            $('#bankTransferPaymentsTable').DataTable().ajax.reload();
        };

        $(document).on('change', '#filterStatus', function() {
            filter();
        });
    });
</script>

问题

从下拉列表中选择状态时，表数据不会刷新/重新加载。我也没有从控制台得到任何输出。

似乎您的代码中有一个

return

语句阻止您的代码（在返回之后）被执行：

public function query(Payment $model)
    {
        $filters = request()->has('search.value') && filled(request('search.value')) ? json_decode(request('search.value'), true)['filters'] : [];

        return $model->newQuery() //Change this here and it should be solved :)
            ->selectRaw('payments.*, orders.phone, orders.status as order_status, orders.total as order_total')
            ->leftJoin('orders', 'payments.order_id', '=', 'orders.id')
            ->whereRaw('payments.bulk_order_key <> ""');

           //... rest of code
    }
