无法添加我的基于原型的内容类型

Question

我正在开发一个附加包，它引入了一些基于原型的内容类型；这些在该包的默认配置文件中定义。

在快速安装程序中（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，并且它们未在 folder_constraintypes_form 中列出。我在文件夹门户类型的 "Allowed content types" 多 select 列表中做了 select 它们。

由于我在 bin/instance debug 会话中从 FactoryTypeInformation._getFactoryMethod 获得了 ValueError，我 "developed" Products.CMFPlone（分支 2.2）并更改了TypesTool.py 像这样：

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() )

debug 会话现在看起来像这样：

>>> 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：

MANAGERS_ONLY = ('Manager',)
MANAGERS_AND_OWNER = ('Manager', 'Owner')

# Permissions
DEFAULT_ADD_CONTENT_PERMISSION = "Add portal content"
setDefaultRoles(DEFAULT_ADD_CONTENT_PERMISSION, MANAGERS_AND_OWNER)

    'MyType': AddMyType,
}
for perm in ADD_CONTENT_PERMISSIONS.values():
    setDefaultRoles(perm, MANAGERS_ONLY)

    security = ClassSecurityInfo()
    implements(IMyType)

    _at_rename_after_creation = True

    schema = MyType_schema

registerType(MyType, PROJECTNAME)

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？ ''（我对灵巧完全没有经验）''

在有人告诉我这样做之前：我已经创建了 a question in the Plone community forum；到目前为止没有运气。如果任一页面上有重要信息，我会同步它。

Answer 1

这些是使您的内容类型可添加的缺失部分：

1.) 通过添加以下内容在 MyCompany/MyProduct/configure.zcml 中注册内容目录：

<include package=".content" />

2.) 添加包含以下内容的文件 MyCompany/MyProduct/content/configure.zcml：

<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.) 通过将 class MyType(*basecls) 替换为 class MyType(ATCTContent) 来修复 MyCompany/MyProduct/content/mytype.py 中随后发生的语法错误。

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视图错误，请随时打开新任务;-)
