SilverStripe.在ModelAdmin中按日期范围搜索

Question

我的DataObject中有date-property.

如何在ModelAdmin中按日期范围进行搜索？

例如:"搜索日期大于2007-13-01且小于2007-17-01的
所有项目" 或"搜索日期介于2007-13-01和2007-17-01之间的所有项目"

现在我只能使用GreaterTranFilter或LessThanFilter进行搜索,但不能同时搜索.

class MyObject extends DataObject {
    private static $db = [
        "Date" => "Date",
    ];
    private static $summary_fields = [
        "Date" => "Date",
    ];

    private static $searchable_fields = [
        "Date" => [
            "field" => "DateField",
            "filter" => "GreaterThanFilter",
            "title" => 'Date from ...'
        ],
    ];
}

此外,搜索字段必须使用日历(datepicker)

DateField:
  default_config:
    showcalendar: true

你能举例说明如何按日期范围进行搜索吗？

有一个WithinRangeFilter,但如果你只使用配置,它不会让你走得太远.这是您真正需要在程序上实现的.

通过重载添加范围过滤器getSearchContext(),然后重载getList()并检查q日期范围的请求参数,并将它们应用于列表.

public function getSearchContext()
{
    $context = parent::getSearchContext();
    $context->getFields()->push(DateField::create('q[Start]','Start'));
    $context->getFields()->push(DateField::create('q[End]','End'));

    return $context;
}

public function getList()
{
    $list = parent::getList();
    $params = $this->getRequest()->requestVar('q');

    $filters = [];
    if(isset($params['Start'])) {
        $filters['Date:LessThanOrEqual'] = $params['Start'];
    }
    if(isset($params['End'])) {
        $filters['Date:GreaterThanOrEqual'] = $params['End'];
    }

    return $list->filter($filters);
}
