I am not surprised that you are formatting a database result.
I am surprised that in the byte code there is an "import time"
(or an import at all).
I tried to reproduce your problem and failed:
bin/zopectl debug
from datetime import datetime
from AccessControl import allow_type
allow_type(datetime)
from Products.PythonScripts.PythonScript import PythonScript
ps=PythonScript('t')
ps.write('''##parameters=dt
... return dt.strftime('%d.%m.%Y')
... ''')
dt=datetime(2006,12,1,20,0,0)
ps.__of__(app)(dt)
'01.12.2006'
And this is the Python Script's code:
f=ps._v_f
from dis import dis
dis(f.func_code)
1 0 LOAD_GLOBAL 0 (_getattr_)
3 LOAD_FAST 0 (dt)
6 LOAD_CONST 1 ('strftime')
9 CALL_FUNCTION 2
12 LOAD_CONST 2 ('%d.%m.%Y')
15 CALL_FUNCTION 1
18 RETURN_VALUE
19 LOAD_CONST 0 (None)
22 RETURN_VALUE
I am using Zope 2.8.1 with Python 2.4.1.
Interesting - in my script there is actually no import just a formatting
statement for something that is subsequently passed to an external method
to generate a PDF but is the same error I get when using datetime types.
The interesting thing is that allow_type explicitly says that extension
types like datetime will not work. I have used "allow_type" in a generic
"Tools" script so that I can use in scripts or PageTemplates (which is
where it should be allowed to be used). I will give your script a go and
see how that works.
Thanks very much for your help and your profound understanding of the
internals of Zope.
Charlie
