Python class browser
by Cary O'Brien 17 Jun '00

17 Jun '00

I'm tired of digging through .py files to find what methods a class supports. Has anyone put together a class browser ZClass w/ external methods that allows you to look at modules, classes, methods, and method arguments via the browser? It *seems* as if python supplies all the pieces (i.e. start with sys.modules and use the pyclbr stuff from there). -- cary

Problem sending mail from Worldpilot
by Bill Anderson 17 Jun '00

17 Jun '00

Hello... I get the following traceback from worldpilot when hitting send on the compose screen. Yes a recipient is specified, as is subject and body. SMTP server is localhost, since all others returned a host not found error (even though they exist, and it finds one to _get_ the email from!). Anyhelp appreciated. Worldpilot crew: How about a link form the worldpilot page for sending these to? Sorry, a Zope error occurred.<p>

Transaction in zodb

Hi, Is transaction build in of ZODB? I have a product which keep a counter property and a inc method which will increase the property with a integer amount. I would like to make sure that concurrent inc call will not cause problem. Is ZODB automatically do transaction and prevent corrupt of data? My class is like this: class Cid( OFS.SimpleItem.Item, # A simple Principia object. Not Folderish. Persistent, # Make us persistent. Yaah! Acquisition.Implicit, # Uh, whatever. AccessControl.Role.RoleManager # Security manager. ): """Cid object. Keep an integer value and provide an way to inc it. """ meta_type = 'Cid' # what do people think they're adding? manage_options = ( # what management options are there? {'label': 'Edit', 'action': 'manage_main'}, {'label': 'View', 'action': ''}, # defaults to index_html {'label': 'Security', 'action': 'manage_access'}, ) __ac_permissions__=( # what permissions make sense for us? ('View management screens', ('manage_tabs','manage_main')), ('Change permissions', ('manage_access',) ), ('Change Cid' , ('manage_edit',) ), ('View Cid', ('',) ), ) def __init__(self, id, title='', initval=0): """initialise a new instance""" self.id = id self.title = title try: self.counter = int(initval) except: self.counter= 0 def inc(self, increment=1): """ inc counter """ self.counter = self.counter+increment return def __repr__(self): '''aa''' return self.counter def __str__(self): ''' a ''' return str(self.counter) def index_html(self): ''' return data ''' return self.counter manage_main = HTMLFile('CidEdit', globals()) # Management Interface def manage_edit(self, title, counter, REQUEST=None): """does this really need a doc string?""" self.title = title try: self.counter = int(counter) except: pass if REQUEST is not None: return MessageDialog( title = 'Edited', message = "Properties for %s changed." % self.id, action = './manage_main', ) I add an object aaa of Cid and make the following call on dtml: <dtml-call "aaa.inc()"> Counter is now : <dtml-var aaa> How could I prevent aaa get updated after inc() is call?

Grüß Dich, There are many freeware utilities out there for generating images on-the-fly. I don't know about Zope products, but I guess it's better for you anyway to handle the details by hand. Check out these links. (I saved them recently from the Python list... haven't tried them myself, yet.) http://www.fred.net/brv/chart/ http://piddle.sourceforge.net/ http://www.object-craft.com.au/paint_doc.html http://www.object-craft.com.au/paint.tar.gz http://www.manning.com/Grayson/chapt11.pdf Alles Gute, Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Using ZClient to Access Another Server: Via Proxy?
by ralf.herold＠charite.de 17 Jun '00

17 Jun '00

Hello, Loren Stafford describes in her "How-To: Using ZClient to Access Another Server" a method that I would like to use, but the Zope Server resides behind a firewall and it requires the usage of a http proxy to access external web servers. Do You know how to achieve this, eg. by modification of the external method mentioned in the How-To, which uses ZClient.py? Thanks for Your help!

I remember that I saw once a product, which could do this. I think it used the PIL-library from python. I can´t find it on Zope.org. Any hints ? Mit freundlichen Grüßen Joachim Schmitz Email: js(a)aixtraware.de Telefon: +49-2464-8851 FAX: +49-2464-905163
