我正在使用Silverstripe Swipestripe模块进行在线商店。由于客户拥有的产品数量，当他们想要对产品进行更改（这种情况经常发生）时，通过网站树导航到每个单独的产品是不切实际的，所以我要这样做。喜欢使用modeladmin列出所有产品，并允许他们按名称/股票代码搜索产品。
我认为这可以像DataObjects一样解决（并且搜索似乎表明人们已经完成了这一点），但是当我在ModelAdmin视图中导航到产品时，我得到：
致命错误：在非对象中调用成员函数stat（） 第3192行的/path/to/folder/wwwroot/framework/model/DataObject.php
<?php

有趣的是，页面类的页面和其他扩展可以正常工作。

任何人都可以建议我在这里做错了什么，或者另外一种方法来做我想要达到的目标吗？
干杯
答案 0 :(得分：1)
以防任何人仍然遇到同样的问题。 因此，如果您已为swipestripe安装了Product Categories模块，则会发生这种情况。 原因是该模块中ProductCategory.php文件中的ProductCategory_Extension类中的私有静态$ searchable_fields。只需注释掉该字段即可。 这是因为dataobject类尝试将类别作为一个类 - 这显然不存在。
如果我有时间，我会解决它并推送到github。只是想在这里更新，以便其他人不要浪费时间去理解为什么它不起作用。
