Laravel-datatables: 如何将参数发送到DataTable服务UsersDataTable类？

如果您使用的是v7，则可以使用：

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

并像访问dataTable类的属性一样访问它。

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

这是我在需要时添加此功能的提交。 尚未在文档中添加。

嗨，谢谢您的答复，我目前在Laravel 5.3.30中使用6.x，

如果我将提交代码复制并粘贴到数据表6.x中，它将起作用吗？

我将提交代码添加到了Datatables 6.x包中，它在DataTable Service类query()很好地工作

    public function query()
    {

        $id = $this->id;

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

        return $this->applyScopes($restaurant);

    }

return $this->applyScopes($restaurant); ， $restaurant显示警告：

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

但是，如果我添加->get()类的东西， return $this->applyScopes($restaurant->get());该警告将消失，但datatable视图将得到如下错误：

DataTables warning: table id=dataTableBuilder - ajax error.

您可以粘贴您的餐厅课程吗？ 我认为您的模型有问题。

无论如何，不​​建议编辑vendor文件夹，因此我决定在v6上也添加流畅的变量。

请更新至v6.27.0以具有此功能。 谢谢！

嗨，这是我目前的餐厅模特班：

嘿yajra，这是$ key = $ this-> attributes; 不是$ key = $ this-> key; 对？
我用了这个$ key = $ this-> attributes;

@jcduenasr该类使用一个魔术的getter方法，该方法从属性中的键中获取值。

嗨，我在表单中有两个日期字段，用于按日期过滤表查询，并防止它带来数千条记录。
问题是，当我尝试使用按钮之一进行导出时，查询未发送日期过滤器，因此我什么也没带。
如何使用按钮发送日期字段以进行导出？

这是我的课。
命名空间AppDataTables;
使用App \ Accesos;
使用YajraDatatables \ Services \ DataTable;

AccesosDataTable类扩展了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);

}
