Php SiverStripe 3：方法'；fortemplate&x27；不存在于'；文件'；

我正在为我的页面创建一个

GridField

，其中

与我的
DataObjects
有很多关系，但在添加数据并保存对象后，它会在CMS中中断页面。我找不出原因，也找不到任何答案。以下是错误和我的代码：

[用户错误]未捕获异常：对象->\u调用（）：方法“fortemplate”在“File”上不存在

        );

        $uploader->setFolderName('firmware');

        return $fields;
    }
}

问题在于这一行：

public static $summary_fields = array(
    // ...
    'FirmwDownloadFile' =>'Firmware Download File'
);

这将尝试在
网格字段中显示
FirmwDownloadFile
，但
FirmwDownloadFile
是
文件<代码>网格字段
不知道如何显示
文件

我们可以做的是在我们的
摘要\u字段中显示
文件
的变量，例如
File.Name
：

private static $summary_fields = array(
    // ...
    'FirmwDownloadFile.Name'
);

private static $field_labels = array(
    // ...
    'FirmwDownloadFile.Name' =>'Firmware Download File'
);

这与更新表单SilverStripe有关

早期版本：

private static $summary_fields = array(
    'Field Name' => 'Model.Field'
);

当前版本：

private static $summary_fields = array(
    'Model.Field' => 'Field Name'
);

您需要切换键/值对。
这是否在SilverStripe 3.0中？还是3.1+？从3.1版开始，静态变量应该声明为
private
。这解决了我最初的问题，但现在在保存数据对象并返回页面后，我得到了以下错误：“[用户警告]无法将响应类型设置为404，因为/home/dataabstract/public\u html/shop/code/ProductPage.php的第1行上有输出。”页面布局完全是这样：www.pinkpoliceman.com/error.png，我可以刷新页面，然后就可以了。。但是一直在发生。在这里，答案是：，我在
