SilverStripe 3.6.1 - 使用renderWith显示数据对象的循环

Question

我正在使用renderWith（）将数据对象数组渲染到模板但是有一些困难。除了基本的内容WYSIWYG编辑器中的内容之外，我现在所拥有的内容不会在指定的模板中呈现任何内容。

作为旁注，我使用短信模块作为参考，因此代码的设置方式与原因相同。

这是我在名为Drawer的数据对象中设置的函数，用于在DrawerContents模板中显示FaqLisitng的列表：

public function parse_shortcode($attributes, $content, $parser, $shortcode) 
{
        $drawers = "";
        if (isset($attributes['Drawers'])) {
            $Idx = explode(',', $attributes['Drawers']);
            $drawerIdx = [];
            foreach ($Idx as $did) {
                $d = Drawer::get()
                    ->filter('ID', $did)
                    ->first();
                if ($d->ID) {
                    array_push($drawerIdx, $d->ID);
                }
            }
            $drawers = implode(',', $drawerIdx);
        }
        $drawerContents = DrawerContent::get()->filter(
            array("DrawerID" => $drawers));

        $drawerContentArray = array();
        foreach($drawerContents as $dca){
            $drawerContentArray = new ArrayData(array(
                'FaqQuestion' => $dca->FaqQuestion,
                'FaqAnswer' => $dca->FaqAnswer
            ));
        }
        return $drawerContentArray->renderWith('FaqListing');
    }

这是FaqListing模板内容：

<% with $getFaqListing %>
    <strong>$FaqQuestion</strong><br/>
    $FaqAnswer
<% end_with %>

我注意到如果我删除了with块，我确实得到了parse_shorcode函数中调用的每个DrawerContent数据对象的最后一个条目，只有第一个条目 - 而不是整个条目每个DrawerContent数据对象的列表。如果我使用循环而不是使用。

，我会得到相同的结果

我不确定自己做错了什么，但我觉得我已经接近正确设置。

作为参考，如果它可以帮助提供解决方案，这里是Drawer数据对象的完整代码：

<?php

class Drawer extends DataObject {

    private static $db = array(
        'FaqCategoryName' => 'varchar(250)',
    );

    private static $summary_fields = array(
        'FaqCategoryName'       => 'FAQ Category Name',
    );
    private static $has_many = array(
        'DrawerContents' => 'DrawerContent',
    );
    /**
     * Parse the shortcode and render as a string, probably with a template
    Add a comment to this line
     * @param array $attributes the list of attributes of the shortcode
     * @param string $content the shortcode content
     * @param ShortcodeParser $parser the ShortcodeParser instance
     * @param string $shortcode the raw shortcode being parsed
     * @return String
     **/
    public function parse_shortcode($attributes, $content, $parser, $shortcode) {
        $drawers = "";
        if (isset($attributes['Drawers'])) {
            $Idx = explode(',', $attributes['Drawers']);
            $drawerIdx = [];
            foreach ($Idx as $did) {
                $d = Drawer::get()
                    ->filter('ID', $did)
                    ->first();
                if ($d->ID) {
                    array_push($drawerIdx, $d->ID);
                }
            }
            $drawers = implode(',', $drawerIdx);
        }
        $drawerContents = DrawerContent::get()->filter(
            array("DrawerID" => $drawers));

        $drawerContentArray = array();
        foreach($drawerContents as $dca){
            $drawerContentArray = new ArrayData(array(
                'FaqQuestion' => $dca->FaqQuestion,
                'FaqAnswer' => $dca->FaqAnswer
            ));
        }
        return $drawerContentArray->renderWith('FaqListing');
    }

    public function getShortcodableRecords() {
        return Drawer::get()
            ->map('ID')
            ->toArray();
    }

    /**
     * Returns a list of fields for editing the shortcode's attributes
     * in the insert shortcode popup window
     *
     * @return Fieldlist
     **/
    public function getShortcodeFields()
    {
        $all = Drawer::get()->map('ID');

        $DrawersMultiList = ListboxField::create("Drawers", "Drawers")
            ->setMultiple(true)
            ->setSource($all);

        return FieldList::create([
            $DrawersMultiList,
        ]);


    }
    public function canView($member = null){
        return true;
    }

    public function canEdit($member = null) {
        return true;
    }

    public function canCreate($member = null) {
        return true;
    }

    public function getTitle(){
        $title = $this->FaqCategoryName;

        return $title;
    }

}

class DrawerAdmin extends ModelAdmin {
    private static $managed_models = array('Drawer');
    private static $url_segment = 'Drawers';
    private static $menu_title = 'Drawers';
}

DrawerContent数据对象的代码：

<?php

class DrawerContent extends DataObject {

    private static $db = array(
        'FaqQuestion' => 'varchar',
        'FaqAnswer' => 'HTMLText',
    );
    private static $has_one = array(
        'Drawer' => 'Drawer',
    );
    private static $summary_fields = array(
        'FaqQuestion'       => 'FAQ Question',
    );

}

$ getFaqListing函数，它在Page.php

中创建

public function getFaqListing() {
    return DrawerContent::get();
}
