我正在开发一个附加包，它引入了一些基于原型(prototype)的内容类型； 这些在该包的默认配置文件中定义。
在 Quick-Installer 中(重新)安装我的包后，我可以在类型工具中看到我的类型；但我无法将它们添加到 TTW，并且它们未列在 folder_constraintypes_form 中。我确实在文件夹门户类型的“允许的内容类型”多选列表中选择了它们。
因为我在 bin/instance debug session 中从 FactoryTypeInformation._getFactoryMethod 得到了一个 ValueError，所以我“开发”了 产品。 CMFPlone(分支 2.2)并像这样更改了 TypesTool.py:
from pprint import pprint # ADDED
...
class FactoryTypeInformation(TypeInformation):
...
def _getFactoryMethod(self, container, check_security=1):
if not self.product or not self.factory:
raise ValueError, ('Product factory for %s was undefined' %
self.getId())
pd = container.manage_addProduct # ADDED
p = container.manage_addProduct[self.product]
self_product = self.product # ADDED
self_factory = self.factory # ADDED
m = getattr(p, self.factory, None)
if m is None:
pprint(locals()) # ADDED
raise ValueError, ('Product factory for %s was invalid' %
self.getId())
if not check_security:
return m
if getSecurityManager().validate(p, p, self.factory, m):
return m
raise AccessControl_Unauthorized( 'Cannot create %s' % self.getId() )
调试 session 现在看起来像这样:
>>> root = app.plone
>>> from Products.CMFCore.utils import getToolByName
>>> tmp_folder = root.temp
>>> type_name = 'MyType'
>>> types_tool = getToolByName(tmp_folder, 'portal_types')
>>> type_info = types_tool.getTypeInfo(type_name)
>>> type_info
<DynamicViewTypeInformation at /plone/portal_types/MyType>
>>> new_content_item = type_info._constructInstance(tmp_folder, 'shiny_new_object')
{'check_security': 0,
'container': <ATFolder at /plone/temp>,
'pd': <App.FactoryDispatcher.ProductDispatcher object at 0x227afd0>,
'p': <App.FactoryDispatcher.FactoryDispatcher object at 0x7b97450>,
'self': <DynamicViewTypeInformation at /plone/portal_types/MyType>,
'm': None,
'self_factory': 'addMyType',
'self_product': 'MyCompany.MyProduct'}
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/opt/zope/instances/zope-devel/src/Products.CMFCore/Products/CMFCore/TypesTool.py", line 551, in _constructInstance
m = self._getFactoryMethod(container, check_security=0)
File "/opt/zope/instances/zope-devel/src/Products.CMFCore/Products/CMFCore/TypesTool.py", line 467, in _getFactoryMethod
self.getId())
ValueError: Product factory for MyType was invalid
因此，FactoryDispatcher 缺少必要的 addMyType 属性。
可能是我的声明不完整？
这是我的:

- Archetypes 不应该负责创建缺少的
addMyType方法吗？ - 什么会导致失败？
- 我的配置中是否明显缺少某些内容？
- 到目前为止，该站点仅包含基于 Archtypes 的对象。如果我现在添加基于敏捷的类型，我会遇到麻烦吗？ ''(我对 Dexterity 完全没有经验)''
在有人告诉我这样做之前:我创建了 a question in the Plone community forum已经;到目前为止没有运气。如果任何一个页面上出现重要信息，我都会同步它。
最佳答案
这些是使您的内容类型可添加的缺失部分:
1.) 在 MyCompany/MyProduct/configure.zcml 中注册内容目录通过添加:
<include package=".content" />
2.) 添加文件 MyCompany/MyProduct/content/configure.zcml内容如下:
<configure
xmlns="http://namespaces.zope.org/zope"
xmlns:five="http://namespaces.zope.org/five"
i18n_domain="MyCompany.MyProduct">
<class class=".mytype.MyType">
<require
permission="zope2.View"
interface="..interfaces.IMyType"
/>
</class>
</configure>
3.) 修复 MyCompany/MyProduct/content/mytype.py 中出现的语法错误通过替换 class MyType(*basecls)与 class MyType(ATCTContent) .
最后但并非最不重要的是，删除以前使事情正常进行的尝试。最好的办法是将类型外包给专用的 pckg 并使用 zopeskel 创建它，imo。
对于添加类型后出现的 View 错误，请随意打开一个新任务;-)
