Hello,
I try to build CMF Product.
I read chapiter 13 "Writing a Product in Python" of "The Definitive Guide to Plone" book (http://docs.neuroinf.de/PloneBook/ch12.rst?image_scale=narrow).
I look the install method of Extensions/Install.py file.
I the book, I've this code :
def install(self):
out = []
typesTool = getToolByName(self, 'portal_types')
skinsTool = getToolByName(self, 'portal_skins') if id not in typesTool.objectIds():
typesTool.manage_addTypeInformation(
add_meta_type = factory_type_information['meta_type'],
id = factory_type_information['id']
)
out.append('Registered with the types tool')
else:
out.append('Object "%s" already existed in the types tool' %
(id))When I use this code, I've this error :
""" 2005-05-05 19:36:33 failed: Traceback (most recent call last):
File "/home/harobed/newzope/Products/CMFQuickInstallerTool/QuickInstallerTool.py", line 235, in installProduct
res=install()
File "/home/harobed/myzope/lib/python/Products/ExternalMethod/ExternalMethod.py", line 232, in __call__
return f(self.aq_parent.this(), *args, **kw)
File "/home/harobed/newzope/Products/ZHelloWorld/Extensions/Install.py", line 22, in install
)
File "/home/harobed/newzope/Products/CMFCore/TypesTool.py", line 598, in manage_addTypeInformation
raise ValueError, (
ValueError: Meta type ZHelloWorld is not a type class. """
ZHelloWorld is my product name.
Now, in source code tarbal example, I've this :
from Products.CMFCore.TypesTool import FactoryTypeInformation as fti_klass
...
def install(self):
out = []
typesTool = getToolByName(self, 'portal_types')
skinsTool = getToolByName(self, 'portal_skins') if id not in typesTool.objectIds():
typesTool.manage_addTypeInformation(
fti_klass.meta_type,
id = plone_product_name
)
out.append('Registered with the types tool')
else:
out.append('Object "%s" already existed in the types tool' %
(id))Here, the value of fti_klass.meta_type is "Factory-based Type Information".
What is the good method ? Why I must add type class with fti_klass meta_type name and not my meta_type value ?
Thanks for your help, -- St�phane
