Zope 2:在自己的产品中使用manage_addProduct (AttributeError)

Question

我是Zope2编程领域的新手。所以，如果我问的是明显的问题，请耐心等待。

我创建了一个示例产品。在ZMI中一切都很好:我可以轻松地添加/删除产品并更改其属性。但是，我不能在代码中或使用Zope调试模式添加产品。我一遍又一遍地阅读OFS.Folder代码(作为参考)，找出任何不同之处都无济于事。

如果有人能给我一点提示，我将不胜感激。蒂娅

产品代码：

##

    """Devistan product implementation.
    """
    implements(IDevistan)
    meta_type = 'Devistan Site'
    _properties = ({'id': 'title', 'type': 'string', 'mode': 'wd'},)
    manage_options = (

    def __init__(self, id=None):

    obj = Devistan(id)
    obj.title = title
    self._setObject(id, obj)
    if REQUEST is not None:
        return self.manage_main(self, REQUEST, update_menu=1)
    return "<p>Devistan instance successfully installed: <tt>%s</tt>" % id


def initialize(self):
    self.registerClass(
        Devistan,
        constructors=(manage_addDevistanForm,
                      manage_addDevistan))

__init__.py代码：

from bahmanm.devistan.implementation import Devistan


def initialize(self):
    """Registers Devistan product.

    Devistan.initialize(self)

要添加您的产品，只需直接导入manage_addDevistan函数：

from bahmanm.devistan.implementation import manage_addDevistan

manage_addDevistan(somefolder, 'someid')
