如何在 SilverStripe 4 上编辑 many_many_extraFields？

Question

我Data在多对多关系中添加了一个额外的字段，但我不知道如何编辑它。特征private static $belongs_many_many = [        'Model' => Model::class    ];模型private static $many_many = [        'Features' => Feature::class,    ];private static $many_many_extraFields = [    'Features' => [        'SortOrder' => 'Int',        'Data' => 'Varchar'    ]];-- / --$features = Feature::get();$searchFeaturesButton = new GridFieldAddExistingSearchButton();$searchFeaturesButton->setSearchList($features);$featureConfig = GridFieldConfig_RelationEditor::create();$featureConfig->removeComponentsByType([GridFieldAddExistingAutocompleter::class, GridFieldEditButton::class, GridFieldAddNewButton::class]);$featureConfig->addComponent(new GridFieldOrderableRows());$featureConfig->addComponent($searchFeaturesButton);$featureGrid = GridField::create('Features', 'Features', $this->Features(), $featureConfig);$field->addFieldToTab('Root.Main', $featureGrid);-- / --如何Data在我的 GridField 中查看一列并使其可编辑？排序工作正常，因为它由 GridfieldOrderableRows()

在 SilverStripe 3 和 4 中，我们可以使用 SilverStripe GridField 扩展模块的GridFieldEditableColumns 功能来编辑many_many_extraFields数据。

以下是如何执行此操作的示例：

// Features field existing search button

$featuresGridFieldSearchButton = new GridFieldAddExistingSearchButton();

$featuresGridFieldSearchButton->setSearchList(Feature::get());

// Features field editable columns

$featuresGridFieldEditableColumns = new GridFieldEditableColumns();

$featuresGridFieldEditableColumns->setDisplayFields([

    'Title' => [

        'title' => 'Title',

        'field' => ReadonlyField::class,

    ],

    'Data' => [

        'title' => 'Data',

        'field' => TextField::class,

    ],

]);

// Features field config including base GridFieldConfig_RelationEditor components, custom search button, editable columns and orderable rows

$featuresGridFieldConfig = GridFieldConfig::create();

$featuresGridFieldConfig->addComponent(new GridFieldButtonRow('before'));

$featuresGridFieldConfig->addComponent($featuresGridFieldSearchButton);

$featuresGridFieldConfig->addComponent(new GridFieldToolbarHeader());

$featuresGridFieldConfig->addComponent(new GridFieldTitleHeader());

$featuresGridFieldConfig->addComponent($featuresGridFieldEditableColumns);

$featuresGridFieldConfig->addComponent(new GridFieldDeleteAction(true));

$featuresGridFieldConfig->addComponent(new GridFieldOrderableRows());

$featuresGridFieldConfig->addComponent(new GridFieldPageCount('toolbar-header-right'));

$featuresGridFieldConfig->addComponent(new GridFieldPaginator());

$featuresGridFieldConfig->addComponent(new GridFieldDetailForm());

$featuresGridField = GridField::create(

    'Features',

    'Features',

    $this->Features(),

    $featuresGridFieldConfig

);

$fields->addFieldToTab('Root.Features', $featuresGridField);
