我正在为我的页面创建一个 GridField，它与我的 DataObjects 有一个 has_many 关系，但是在添加数据并保存对象后它会中断CMS 中的页面。搜索后我无法弄清楚原因或找不到任何答案。这是错误和我的代码:

最佳答案

问题是这一行:

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

这将尝试在 GridField 中显示 FirmwDownloadFile，但 FirmwDownloadFile 是一个 File。 GridField 不知道如何显示 File。

我们可以做的是在 summary_fields 中显示一个 File 变量，例如 File.Name:

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

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