The products must register help during their initialization def initialize(context): .... context.registerHelp() context.registerHelpTitle('Zope Help') and they must have a "help" subfolder. Look at "Products/ZCatalog" for an example. Dieter

I would expect, you get a KeyError. Right? <dtml-with new_folder_ID> tries to access the object with the name "new_folderID". But the new folder was created with a name "REQUEST['new_folderID']". Try: <dtml-with "REQUEST['new_folderID']"> Dieter

Why? I guess: <dtml-call "_[userid].propertysheets[1].manage_changeProperties(REQUEST)"> <dtml-in "objectValues(['zclassuser'])"> <dtml-var reindex_object></dtml-in> will work, too. In the case, that does not work, you call "reindex_object" for the object for which the DTML code was called (probably a folder). This is not the same as the object changed "_[userid]". Otherwise, you would have been able to omit this "_[userid]". In the working case, you call "reindex_object" for each of your class instances. This includes obviously the one that has been changed.

Maybe Python 1.6 and Zope 2.2.2 do not fit well together. Dieter

LocalFS question
by Leichtman, David J 12 Dec '00

12 Dec '00

How do you access an individual object in a LocalFS? By that, I mean: If I wanted the last_mod time of any Zope object, I could say <dtml-var "object.subobject.bobobase_modification_time">. However, if you try to do the same thing with a LocalFS object, i.e. <dtml-var "localfs_object.localfs_subobject.bobobase_modification_time">, you get the error NameError: localfs_subobject This leads me to believe that LocalFS subobjects are not really objects. But then how does the Zope management interface deal with them, and how can I?

Zope is a I would like to get a clarifaction on this. It seems best to provide support for Python 2.x and provide a patch for 1.5.2 if need be. >pretty large codebase and if nothing else, introducing unicode Seem to me a 2.3 designation gives you some leeway to provide 2 versions release perhaps 2 versions of Zope 2.3. One that incorporates work already done by members in the community. See links below for Python 2.x support and Zope 2.2.4. http://www.zope.org/Members/stevea/unicode_for_224.patch.gz http://www.zope.org/Members/htrd/wstring Don't be like a certain company that stopped dos at 6.0. Or did they? The point is probably at some point in the future Zope will become the Windows of Python.

Someone joins the network and is taken to a mandatory form where they fill in eight pages of information about themself. They submit the information. Everything's cool up to this point. A year later, they graduate from school and become a farmer. They still want to be a member of the network. They log back in, re-access their form information, deselect the checkbox for "student" and select the "professional" checkbox. I can't get my zportal ZODB to recognize the deselection. You'll notice in the code above that when the box is checked and submitted, the value "member._____" is submitted to the database. To display a checked box when the page is re-loaded, I use <dtml-if "member.______">checked</dtml-if> within the <inpupt type=boolean...> tag. Now, I want to tell the database that if a form page is re-submitted and a boolean box that was checked is no longer checked, it's previous value should be deleted from that user's record. Can anybody shed any light on the matter?

I need to refresh my port to NetWare, and want to knock off both Python 2.0 and Zope 2.3 in one go. Anyone know if it works on 2.0? Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com AOL-IM: BKClements
