One (the?) solution is to pass the 'under' namespaceto the script, that is to specify _ as the value of 'bind namespace' in the Python Script. The you have access to that namespace where (I think) the variable val has been 'pushed'. To get the var out of it you can: 1) specify val as parameter and use it 'normally' ## Script (Python) "script" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters=val ##title= ## return 'script - ' + str(val) 2) do not specify it as parameters and get it explicitly from the namespace ## Script (Python) "script" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## return 'script - ' + str(val) Not really sure about the 'theory', but it works in practice. bye, Luca

Mozillla 0.9.9 and Zope authentication
by Kirk Lowery 11 May '02

11 May '02

Now, before you go and flame me for being off-topic, let me say that I've checked everywhere on the Mozilla sites, searched through Bugzilla, and come up with nothing. I just upgraded from Mozilla 0.9.8 to 1.0RC1. And the next time I tried to access my zope site, the authentication would not work for any user except for the original administrator set up during installation. And even then, the management screen would not complete uploading to the browser and would not refresh. I backed down to 0.9.9, same behavior. I backed down again to 0.9.8 and everything works. I know...I know...it's not a Zope problem, but Mozilla's. But if anyone knows about this, I'd appreciate knowing if a bug has been filed against it under what subject, and especially if there is a workaround. In the meantime, I'm just backing down to 0.9.8 again. TIA. Kirk

xmlrpc and zope objects
by Derek Basch 10 May '02

10 May '02

Hi, Please help me zope gods......... I have been trying to use/learn xmlrpclib with zope using this example: http://www.xml.com/pub/a/2000/01/xmlrpc/index2.html I followed the example and I was able to read the document_src of the 'Test' DTML Method after I repaired the modified xmlrpclib file: http://www.zope.org/Members/teyc/pipermailXMLRPCWoes However, I cant do it again!?. If I connect to the zope server as such: import xmlrpclib z = xmlrpclib.Server('http://localhost:8080/Test', xmlrpclib.BasicAuthTransport('administrator','password')) and attempt to view the document_src method of 'Test' I get a 'resource not found' error. I know the object exists because the URL of http://localhost:8080/Test returns the DTML document in my browser and also the error returned in my python interpreter has the title of the DTML document. What am I doing wrong here? Thanks in advance, Derek Basch __________________________________________________ Do You Yahoo!? Yahoo! Health - your guide to health and wellness http://health.yahoo.com

RE: [Zope] How to check type of variable in DTML
by Schmidt, Allen J. 10 May '02

10 May '02

Thanks! That works great, sort of.... I changed the return to only 'list' or 'string' or 'integer' for easy comparison. In a dtml doc or method it works fine. In a ZSQL it does not. Seems that it always sees the input parameters as strings...never a list - even when entered as a list. ['Ford','Dodge',''] is seen as a string when checked inside a dtml-if in the ZSQL method. Are Pythonscripts handled somehow differently inside a ZSQL method? Or something else?? Thanks all -Allen -----Original Message----- From: Elena Schulz [mailto:elena.schulz@gmx.net] Sent: Friday, May 10, 2002 6:56 AM To: zope(a)zope.org Subject: Re: [Zope] How to check type of variable in DTML Hi Allen, if you want to check the type of a variable use an external python script like: import string def getType(x): if type(x) == type([]): return "type(%s)=list" % (x) if type(x) == type(""): return "type(%s)=string" % (x) if type(x) == type(1): return "type(%s)=integer" % (x) if type(x) == type({1:'s'}): return "type(%s)=dictionary" % (x) if type(x) == type((1)): return "type(%s)=tuple" % (x) if type(x) == type(string): return "type(%s)=module" % (x) else: return "type(%s)=object o. ä." % (x) I took this idea from some earlier postings to the list.

bug in pluggable brains ?
by Geir Bækholt 10 May '02

10 May '02

Zopistas, There seems to be a bug in the machinery for attribute assignement for pluggable brains with ZSQLmethods: I can use Pluggable Brains and their methods , but whenever i try to assign a value to an attribute, AttributeError is raised. i have narrowed my testcase down to the following: simplest ZSQLmethod possible : SELECT 'testBrain' AS t FROM DUAL When using the following class definition: class Test: def __init__(self): pass def __repr__(self): return "i am a pluggable brain" everything works as expected. if i do this : class Test: def __init__(self): self.teststring = "test" it raises an AttributeError Am i not supposed to use attribute assignment in brains , or is it a bug ? - i cannot seem to find much documentation on the subject.. All information appreciated :) traceback follows: Traceback (innermost last): File /usr/home/geir/zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/home/geir/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/home/geir/zope/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: LockableItem) File /usr/home/geir/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/home/geir/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: te) File /usr/home/geir/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: te) File /usr/home/geir/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: te) File /usr/home/geir/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: te) File /usr/home/geir/zope/lib/python/Products/PythonScripts/PythonScript.py, line 363, in _exec (Object: te) (Info: ({'script': <PythonScript instance at 8f81f60>, 'context': <Folder instance at 90c8f20>, 'container': <Folder instance at 90c8f20>, 'traverse_subpath': []}, (), {}, None)) File Script (Python), line 1, in te (Object: guarded_getitem) File /usr/home/geir/zope/lib/python/AccessControl/ZopeGuards.py, line 151, in guarded_getitem File /usr/home/geir/zope/lib/python/Shared/DC/ZRDB/Results.py, line 175, in __getitem__ File /usr/home/geir/zope/lib/python/Shared/DC/ZRDB/Results.py, line 158, in __init__ (Object: Test) File /usr/home/geir/zope/Extensions/test.py, line 5, in __init__ (Object: Test) AttributeError: (see above) -- Geir Bækholt web-developer geirh(a)funcom.com funcom oslo | webdev-team

ViewAndCopyOnly role
by Bill Kerr 10 May '02

10 May '02

how should I set a role for users of a folder where they can view and copy files only? I've set these permissions: View Management Screen (for seeing the files) Access Contents Info, View (for rendering the files) Add Doc, Images, Files (for copying the files) This almost works but the problem is that with Add Doc, Images, Files (which I need for copying) the users can also add things to this folder and I don't want them to be able to do this. I think I want a permission that allows copying but not adding. - Bill
