如何解决CRUD背包Laravel更新Ajax过滤器后，图形会更新
请避免给我负面评论，谢谢
在Laravel Backpack管理员中，当我们单击“日期范围”过滤器时，它正在过滤表数据，效果很好，但是我希望Graph在更改Ajax过滤器时也能被更改。
据我所知，CrudConTroller中的ajax日期范围过滤器代码：
$this->crud->addFilter([
'type' => 'date_range','name' => 'created_at','label' => 'Date range'
],false,function ($value) { // if the filter is active,apply these constraints
$dates = json_decode($value);
$this->crud->addClause('where','created_at','>=',$dates->from);
$this->crud->addClause('where','<=',$dates->to . ' 23:59:59');
});
图形出现在小部件中，即刀片模板文件：list.blade.php。
$widgets['before_content'][] = [
'type' => 'div','class' => 'row','content' => [ // widgets
[
'type' => 'chart','wrapperClass' => 'mt-4 col-md-12',// 'class' => 'col-md-12','controller' => \App\Http\Controllers\Admin\Charts\UserChartController::class,'content' => [
'header' => 'New Users',// optional
'body' => 'This chart should make it obvious',// optional
]
],],]
解决方法
有许多解决方案，您可以使用php生成图形而不是模板。请参阅中的相关部分。文档。
然后使用request参数过滤图形的数据。我会尝试举一个例子。
,我也需要这个确切的东西。颇为不客气，但我所做的是从date_range过滤器创建一个新的过滤器，而不是仅刷新数据表，而是刷新了整个页面。
是的。如果将其放在resources/views/vendor/backpack/crud/filters/date_range_refresh.blade.php中，则可以使用date_range_refresh代替date_range作为过滤器类型，并获得所需的结果：
{{-- Date Range Backpack CRUD filter --}}
<li filter-name="{{ $filter->name }}"
filter-type="{{ $filter->type }}"
filter-key="{{ $filter->key }}"
class="nav-item dropdown {{ Request::get($filter->name)?'active':'' }}">
<a href="#" class="nav-link dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">{{ $filter->label }} <span class="caret"></span></a>
<div class="dropdown-menu p-0">
<div class="form-group backpack-filter mb-0">

</div>
<input class="form-control pull-right"
id="daterangepicker-{{ $filter->key }}"
type="text"
@if ($filter->currentValue)
@php
$dates = (array)json_decode($filter->currentValue);
$start_date = $dates['from'];
$end_date = $dates['to'];
$date_range = implode(' ~ ',$dates);
$date_range = str_replace('-','/',$date_range);
$date_range = str_replace('~','-',$date_range);
@endphp
placeholder="{{ $date_range }}"
@endif
>
<div class="input-group-append daterangepicker-{{ $filter->key }}-clear-button">
<a class="input-group-text" href=""><i class="la la-times"></i></a>
</div>
</div>
</div>
</div>
</li>
