Dear all,
I noticed recently that Formulator does not work with CMF v2 because
FSForm.py imports from CMFCore.CMFPermissions so I thought I'd fix
this and thought it might be useful. Easier said than done as there
does not seem to be a standard way to find out which version of CMF
is installed which is presumably why the Plone installer devotes a
few lines to it.
I've come up with the following:
# Use existing Zope tools to check for the CMFVersion
import App.Product
import OFS.Application
import os.path
CMFVERSION = None
for priority, product_name, index, product_dir in
OFS.Application.get_products():
if product_name == "CMFCore":
class Dummy(object):
"""Dummy object for a dummy product install"""
def _setObject(self, name, product):
pass
A = Dummy()
A.Control_Panel = Dummy()
A.Control_Panel.Products = Dummy()
package_dir=os.path.join(product_dir, product_name)
OFS.Application.import_product(product_dir, product_name)
productObject = App.Product.initializeProduct(
None, product_name, package_dir, A)
version = productObject.version
version = version.split("-")
major = int(version[-1][0])
if major >= 2:
CMFVERSION = 2
I hope this isn't too weird! I think it is flexible enough to be used
with other Zope Products if required but does beg the question:
shouldn't there be an easier way to do this? Should there be a
standard method of getting a Product's version in Zope.app? I assume
there are other Products that have similar dependencies, although I
am not sure if the problem is in FSForm itself which does some pretty
thoughtless importing.
