Question

我只想在Silverstripe网站的CMS端显示数据库中最近的100个条目。我目前可以看到全部600个，这是不必要的。 silverstripe文档没有帮助，我无法进入他们的论坛提问。

我试图在表的ID上设置一个大于过滤器，但该过滤器不起作用。

这是我的模型管理文件

use SilverStripe\Admin\ModelAdmin;
use SilverStripe\Forms\DateField;
use SilverStripe\Forms\GridField\GridField;
use UndefinedOffset\SortableGridField\Forms\GridFieldSortableRows;
use SilverStripe\Forms\GridField\GridFieldFilterHeader;

class BonusAllocations extends ModelAdmin
{

private static $managed_models = [
    'AffiliateProgram\MemberBonus'
];

private static $url_segment = 'bonus';

private static $menu_title = 'Bonuses Allocations';

public function getList()
{
    $list = parent::getList();

    return $list;
}

}

这是我当前的dataObject

<?php
namespace AffiliateProgram;

use SilverStripe\Forms\TextField;
use SilverStripe\Forms\DropdownField;
use SilverStripe\Forms\GridField\GridField;
use UndefinedOffset\SortableGridField\Forms\GridFieldSortableRows;
use SilverStripe\Security\Permission;
use SilverStripe\ORM\DataObject;


class MemberBonus extends DataObject
{
private static $db = [
    'Amount' => 'Currency',
    'Confirmed' => 'Boolean',
    'Level' => 'Int',
    'Percentage' => 'Int'
];

private static $has_one = [
    'Member' => 'AffiliateProgram\Member',
    'MemberPayment' => 'AffiliateProgram\MemberPayment',
    'PaymentType' => 'AffiliateProgram\PaymentType',
    'ProgramType' => 'AffiliateProgram\ProgramType'
];

private static $summary_fields = [
    'Amount' => 'Amount (USD)',
    'Member.Email' => 'Email', 
    'Level',
    'MemberPayment.PaymentType.Symbol' => 'Recieved As',
    'Percentage' => 'Percentage Bonus Applied',
    'ProgramType.Name' => 'Program Type',
    'MemberPayment.Created' => 'Payment Date',
    // 'Confirmed' => 'Confirmed?',
    'MemberPayment.ID' => 'Payment ID',
    'ID' => 'Bonus ID'
];


public function searchableFields()
{
    return [
        'Member.Email' => [
            'filter' => 'PartialMatchFilter',
            'title' => 'Email',
            'field' => TextField::class,
        ],
        'ProgramType.Name' => [
            'filter' => 'ExactMatchFilter',
            'title' => 'Program',
            'field' => DropdownField::create('ProgramType')
                ->setSource(
                    ProgramType::get()->map('Name','Name')
                )
                ->setEmptyString('-- Any Program --')                
        ],
        'MemberPayment.PaymentType.Symbol' => [
            'filter' => 'ExactMatchFilter',
            'title' => 'Locale (Symbol)'              
        ],
    ];
}
  }

在SilverStripe 4中，为了限制自定义ModelAdmin中的列表，我们可以定义一个getList函数并根据需要修改列表。

以下是自定义ModelAdmin的示例，其中我们调用DataList limit()函数以将条目限制为最多100个项目。

use SilverStripe\Admin\ModelAdmin;

class BonusAllocations extends ModelAdmin
{

    private static $managed_models = [
        'AffiliateProgram\MemberBonus'
    ];

    private static $url_segment = 'bonus';

    private static $menu_title = 'Bonuses Allocations';

    public function getList()
    {
        $list = parent::getList();

        $list = $list->limit(100);

        return $list;
    }

}

如何仅显示CMS中数据库的最新100条结果？
