QuickStart
by Chris Withers 07 Aug '00

Hi, Small niggle... Isn't it time the QuickStart bit the dust? It's quite strange seeing references to Principia and Acqueduct in Zope 2.2 ;-) Doesn't the Tutorial replace this quite comfortably? Just a thought, Chris

Zope is slow on a windows 2000 server
by Meeting Maker Webmaster 07 Aug '00

07 Aug '00

Hello, I've been using Zope on a Linux box without any problem this last month. I now have to move the Zope server to it's final location, which is a Windows 2000 server (it's not my choice ;-( I am trying to get the user authenticated based on his IP address to allow everybody on the subnet we are here to access the Zope server, but not other IPs. This works fine except it is really slow (about 5 seconds to go to an object to start downloading). I've tried it on a clean Win2k box to check if I had a problem with my configuration, but it didn't change anything. Here are the basic operations I did. First create a local role "test" in / that has the same authorization as anonymous. Then disable any authorization for this Anonymous user. Create a user in acl_user which don't have a password but has a domain entry 192.168.0.* and the role "test". Now when I connect from the 192.168.0. subnet, I have access to the Zope server, but it is very slow to answer. When I add a user that has to log in (password instead of IP check), it goes much faster. I am using Zope 2.2.0 with the built-in Medusa web server. As I am with the Win2000 questions, is there a way to configure IIS to behave like Apache an the rewrite rules? Thank you for your help.

threading
by Nicholas Lo 07 Aug '00

07 Aug '00

Just a simple question. According to Amos' How-To: Thread Safety in Zope 2, what is mutable global or shared variables?? What is the scope of such global variables? Zope wide? module wide? If global variable is not permitted, how can I approach thread programming in Zope? Without global variables, how can I control threads? Please kindly help Regards, Nicholas Lo

Newbie question: referring to <dtml-call> documents
by David Loeffler 07 Aug '00

07 Aug '00

My site has a number of DTML Document objects which simply redirect the user to another site. These are all created automatically as clones of each other. The text of the document is simply <dtml-call "RESPONSE.redirect(dest)"> and dest is a property automatically set on creation. I need to provide a simple form to allow users to edit the value of this property, so I have to retrieve the current value of the property. However, whenever I try to get hold of this with anything like <dtml-var "_[objId].getProperty(dest)"> (objId is the id of the document) it simply redirects the user immediately to the site named by dest. How do I just get the property value as a string?

RE: [Zope] Installing ZOPE on a Digital platform

Alexandru, You'll need to get the source code and compile it yourself. Tru64 isn't a DC-supported platform, but it may compile properly.

RE: [Zope] Python Method question
by Chris McDonough 07 Aug '00

07 Aug '00

Do you mean you want to use a Python Method (in the sense of a methodish object instantiated from Evan Simpson's Python Method Product) from a Python Product? You *should* be able to call it by getting a hold of it through acquisition or by otherwise getting a hold of an object in the ZODB and traversing from it. > -----Original Message----- > From: entropia [mailto:entropiamax@jazzfree.com] > Sent: Monday, August 07, 2000 3:20 AM > To: zope(a)zope.org > Subject: [Zope] Python Method question > > > I hava a question regards Python Method: How can I > import a Python Method from a Product module? > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

edit_propertiesForm traceback
by Jean Jordaan 07 Aug '00

07 Aug '00

Hi Zopers .. I'm trying to get a Zclass of mine to be properly catalog-aware. This is turning out to be quite a mission, unless I'm seriously astray. First I followed the steps in http://www.zope.org/Documentation/How-To/ZCatalogTutorial/ and then I tried to follow http://www.zope.org/Members/AlexR/CatalogAware/ . Everything seemed to go OK until I attempted to make http://www.zope.org/Members/AlexR/CatalogAware/edit_props.zip work for me. That gets me: Error Type: TypeError Error Value: string member test needs char left operand  when I try to edit the properties of an instance of my Zclass. Itamar's dtml is a bit too subtle for me to follow at this stage. Anyone know what's happening? I don't see any "<string>" in edit_propertiesForm, which is what triggers this traceback. -- jean

ZClass authorization problem (You are not authorized to access manage_changeProperties)
by Gaspard, Bradley S 07 Aug '00

07 Aug '00

I have created a new ZClass which contains a dtml method that first clones an object and then edits it's properties: <dtml-with manage_clone(News, REQUEST['new_id'], REQUEST)"> <dtml-call manage_changeProperties( title=REQUEST['new_title'], blah blah blah, )"> </dtml-with> When I fill out the 'add' form and try to create a new instance I am presented with the error message (as a user with a manager role): You are not authorized to access manage_changeProperties I am able to successfully create an instance if I am the superuser. How do I fix this?? Brad

ZPatterns Question
by RC Compaan 07 Aug '00

07 Aug '00

I created a ZClass called "Product" with Dataskin as baseclass. I also added a specialist called ProductManager containing a default rack. Under storage for the rack I selected the newly created Product ZClass. My product ZClass needs to query both a RDBMS and the ZODB for attributevalues. At this point I get lost. I guess i should add an attributeprovider plug-in??? What should go into the fromexpr and attrsexprs properties of the attributeprovider? Should one add an attributeprovider for each attribute of the product? Roché

Sth wrong with ZCatalog?
by Marcin Kasperski 07 Aug '00

07 Aug '00

I have some strange problem with ZCatalog: after clicking 'Find items to catalog' I get Zope error: Error Type: IndexError Error Value: list index out of range Traceback (innermost last): File /opt/Zope-2.2.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /opt/Zope-2.2.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 187, in publish File /opt/Zope-2.2.0-linux2-x86/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File /opt/Zope-2.2.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 171, in publish File /opt/Zope-2.2.0-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_catalogFoundItems) File /opt/Zope-2.2.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_catalogFoundItems) File /opt/Zope-2.2.0-linux2-x86/lib/python/Products/ZCatalog/ZCatalog.py, line 321, in manage_catalogFoundItems (Object: ElementWithAttributes) IndexError: (see above) I have already working ZCatalog, all I wanted was to add a few new pages to it. Maybe the problem has something to do with SiteAccess rule present in my directory? By the way: as I need to add only 5 pages, is it possible to add them to zcatalog manually? -- Serwis nie tylko mieszkaniowy: http://www.mk.w.pl | | One way to perform analysis is to build models and discuss them with | users.
