I'm new to this list; fairly new to Zope. Thought you might appreciate a fresh data point: 'Zopelet' works for me. It's clearly a code snippet that runs on the Zope server. It may not make any sense in a vacuum, but it communicates in this crazy mixed up Internet world. /alastair/ Alastair Dallas

Login Manager/Latest Zope -possible bug
by Luca Mearelli 23 Oct '00

23 Oct '00

Hello, I had a strange problem when trying out LoginManager v0.8.8b1 with the latest cvs Checkout (as of Oct.23), here is the traceback trying to add a LoginManager (The form didn't show up): Error Type: NameError Error Value: path ... Traceback (innermost last): File /usr/local/tmp/Zope2/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/tmp/Zope2/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/tmp/Zope2/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /usr/local/tmp/Zope2/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/tmp/Zope2/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: addLoginManager) File /usr/local/tmp/Zope2/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: addLoginManager) File /usr/local/tmp/Zope2/lib/python/App/special_dtml.py, line 120, in __call__ (Object: addLoginManager) (Info: /usr/local/tmp/Zope2/lib/python/Products/LoginManager/addLoginManager.dtml) File /usr/local/tmp/Zope2/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: addLoginManager) File /usr/local/tmp/Zope2/lib/python/DocumentTemplate/DT_In.py, line 633, in renderwob (Object: UserSourcesMetaTypes(this())) File /usr/local/tmp/Zope2/lib/python/DocumentTemplate/DT_Util.py, line 331, in eval (Object: UserSourcesMetaTypes(this())) (Info: UserSourcesMetaTypes) File /usr/local/tmp/Zope2/lib/python/ZPublisher/HTTPRequest.py, line 772, in __getitem__ NameError: (see above) after looking at the LM code I found that the manage_addLoginManagerForm is defined in LoginManager.py: ... manage_addLoginManagerForm = HTMLFile('addLoginManager', globals(), UserSourcesMetaTypes = PlugInFinder(LoginManager.UserSourcesGroup), LoginMethodsMetaTypes = PlugInFinder(LoginManager.LoginMethodsGroup)) ... At first I thought it could have been a LM problem, removing UserSourcesMetaTypes(this()) let the form appear, but when I focused on the UserSourcesMetaTypes work, and how the user sources PlugIns get installed I found nothing (It was actually my first test with LM & ZPatterns), moreover there was no mention of such problems by anyone else on the Mailing Lists. Then I tried to it on a Zope 2.2.0 (released) and it worked fine adding the LM. So it should have been something with my Zope CVS checkout, when looked at the HTTPRequest.py file at the line shown in the Traceback, i found a possible error with "__getitem__" When it tries to return the value of UserSourcesMetaTypes, it enters the "if key[:1]=='U':" at line 760 since UserSourcesMetaTypes starts with 'U', but match is empty, therefore path is not initialized and at the line 772 we have the NameError. Putting the lines 772-774 inside the "if match is not None:" fixed the problem (I included a diff for this), is it the right way to go, is it enough? I think so but I have a small knowledge of Zope internals so I'm not completely sure i.e. if we want to match only the env.variables starting with "URL" why not even change the "if key[:1]=='U':" into "if key[:3]=='URL':"?

Excluding meta_types
by morten＠esol.no 23 Oct '00

23 Oct '00

When I'm building a class which inherits from the OFS.Folder.Folder, how do I exlude the meta_types it brings with it (if it's there they come from). In other words, if I have a class, with meta_type 'MessageFilterFolder', which should only be able to contain instances of meta_type 'MessageFilter', what do I do (i.e. exlude all the other meta_types)? Thanks in advance. -Morten

How do I authenticate myself when using the Zope debugger? (I've seen this before I think, but I couldn't find it) Thanks. -Morten

Problems with offline MS IE 5
by Ross Boylan 22 Oct '00

22 Oct '00

I recently tried doing some Zope development on a laptop and ran into a problem: when I updated a product the updates did not "take." In particular, when I edited the text in a .dtml file and restarted Zope, I still saw the old text when I got to the appropriate point (the file was wrapped in an HTMLFile() and used for creating a new instance of one of the products in the package). I think I checked all of the following: * the file was getting updated * all instances of explorer were shut down * MSIE options set to "Check for newer version of stored page on every visit to the page" A notable peculiarity was that whenever I tried to access my local zope, I would get a "you are offline, do you wish to go online" message (I even used localhost as the machine name!). I would say yes, it would say it couldn't connect and ask if I wanted to try again. I said yes, but then I ran into the problems described above. Zope 2.2.2 on MS W2K with MS IE 5.0. Does this ring any bells with anyone? Is it an IE problem? a Zope problem? an interaction?

Re: [Zope] IIS and PCGI
by Andy McKay 20 Oct '00

20 Oct '00

Well I fixed this using a ISAPI filter which I will release soon (once I have some time) that takes a url /a/b/c/x.pcgi/f/g/h, and passes /a/b/c/x.pcgi to IIS so the file will run and /f/g/h to Zope. My next question is has anyone succeeded in getting this to work to another box over a mapped or shared win32 drive? I mapped g:\ to my zope host, and then specified PCGI_PUBLISHER=g:\pcgi\pcgi_publisher.py in my pcgi file. The problem seems to pcgi-wrapper.exe which does not like a mapped drive. (line 485 of parseinfo.c keeps spitting out missing publisher)... Thanks in advance and apologies for the cross post to zope-dev but it is more of a zope-dev question. ----- Original Message ----- From: "Andy McKay" <andym(a)ActiveState.com> To: <zope(a)zope.org> Sent: Tuesday, October 17, 2000 1:33 PM Subject: [Zope] IIS and PCGI > Im fiddling with IIS and PCGI, I've looked at > (http://www.zope.org/Members/brianh/iis_howto) the docs and got the server > to work correctly in that http://127.0.0.1/zope.pcgi is the same as > http://127.0.0.1:8080/ > > However it doesnt seem to be carrying through the trailing path info (or / > 's) for example > http://127.0.0.1/zope.pcgi/manage brings up 404.

I'm going to be out of town for a few days, and won't be as quick to respond to e-mails, if I respond at all during that time. Ty will still be around, though, to answer all your ZPatterns and LoginManager questions. Right, Ty? ;)

Object references from dtml
by Ross Boylan 20 Oct '00

20 Oct '00

I have a log composed of sublogs, and so on. I would like for people to be able to see some kind of summary (e.g., short versions of the logs down n levels) on the screen and then click on one of interest and see a fuller display of it. Is there a good way to do this using dtml? I've thought of two approaches. The "standard" zope way seems to be to make each log folderish, and give each entry an id. Then I can embed the address in the html. The problem with this is that I would have to make up the id's and add extra machinery that the logs don't really need. I'm leaning toward a second approach, of getting an object id and putting it in the html. This also raises some issue. * Will the id be stable in the face of the db potentially dematerializing objects underneath? * If I use a persistent id (_p_oid, I think), will that be stable? * (Also, I'll need to be sure everything has persisted, but I think I can do that by forcing a transaction end before getting the _p_oid). * Can I map from object id back to object? (_p_jar.something or other) * Will this be robust across database changes (minimally, from ZODB to ZEO)? * Will the object id consist of characters which can be embedded easily in html?

Inheritable Propertysheets!???!!?!?!?!!
by Alexander Schonfeld 20 Oct '00

20 Oct '00

I'm doing an experiment... If I add more '!' and '?' marks will I get a response. Soon with enough experimentation I can find the optimal number and frequency of variation. I want to inherit the properties of one zclass in another zclass, but it seems to cause some namespace clashing... shouldn't this be possible? Working with the instance of the class is fine, but inter-zclass inheritance (acquisition?) would be nice... Cool feature? Am I missing something?

Lists of Objects
by Jack Fitzgerald 19 Oct '00

19 Oct '00

Hello, I am currently keeping a list of objects sorted in a particular object. I am wondering if anyone has an opinion about whether I should keep just the 'id' in this list or if it is ok to actually keep a reference to the object in the list. When I use the list at a later point in time I will need to access several attributes of the object. If I keep the 'id' I would have to find the object for each entry in the list. Thanks in advance for any opinions. -Jack Fitzgerald
