Question

我正在使用Plone 4.0.1并且搜索portlet存在问题。正常搜索和实时搜索工作正常，但当我尝试使用高级搜索（通过mysite / search_form）时，我得到以下错误堆栈：

感谢您的帮助！

Answer 1

您似乎对portal_types有问题，请检查一切是否正常。也许是一个内容类型，名称中包含一些名称或者产品损坏？

Answer 2

这可以通过适当类型的类型导入来解决。包装简介。

有一些产品或Zope插件已经安装了一半。

强力修复是重新安装所有插件，希望其中一个插件会注册该类型。

然而，对于更“完美主义”的方法：

查找违规类型
使用Products.PDBDebugMode在fg中运行zope（这使得plone在异常时输入pdb）

AttributeError: 'NoneType' object has no attribute 'Title'
> /path/to/your/plone/instance/PythonExpr(1)<expression>()
(Pdb) portal_types
<TypesTool at /plonesite/portal_types>
(Pdb) type
'NameOfOffendingType'   #### <------ HERE!!!!!!
(Pdb) portal_types.getTypeInfo(type) is None
True   ####<--- yup, sure is!!!

2）访问ZMI并在您的plone网站下，检查类型工具。您应该注意到未列出步骤1中标识的违规类型。

3）找到定义此Object的python包和配置文件'types.xml'：你应该在types.xml中看到这个（希望如此）

 <object name="NameOfOffendingType"
    meta_type="Factory-based Type Information with dynamic views"/>

4）现在您已了解该软件包，访问ZMI并在您的plone站点下进入“门户网站设置”并单击“导入”选项卡。选择“选择配置文件或快照”下的包/产品（您可以在包的configure.zcml中找到配置文件名称）选择“类型工具”并单击“导入所选步骤”

5）从这里开始，您可以在步骤2中重新检查“类型工具”。您现在应该看到列出的“违规类型”。

6）返回并再次尝试高级搜索。也许这次会奏效。

Answer 3

可能是敏捷错误，Title的访问者返回None，目录将其缓存在元数据/大脑中 - 然后模板会阻塞。升级到Dexterity 1.0.3 - IIRC应该为你解决。

Plone高级搜索不起作用
