So that we don't lose track of this in the list traffic, could you please submit this to the Collector as a "Feature with Patch" (bugs/features with patches get priority treatment)? http://classic.zope.org:8080/Collector/Collector/developer_input Paste the patch into the "Description" field, along with the explanation.

Please look at the patch submitted in the Collector to replace the sendmail logic with calls to the standard Python library's smtplib module (which wasn't available when the MailHost product was written): http://classic.zope.org:8080/Collector/1005/view This patch has been accepted and should be in the next release of Zope -- I _think_ it will help with your problem, but I don't know for sure. > > If any mail gurus have any suggestions, I'd appreciate it.

Re: [Zope] SQLmethods in a product...

I don't know if I was going about calling things in the same way - I stole my code from the SQL methods stuff distributed with Zope - but I had exactly the same trouble. I couldn't get hold of the database connection because in __init__ it seems like the object isn't yet in the acquisition tree (or whatever, I'm not too well-versed on the python jargon). I ended up just hanging onto the ID and keeping a flag saying I hadn't finished initing yet - and the first time the user tries to do anything with the object (after it's been instantiated) getting a reference to the actual connection and doing the necessary init. If anyone knows how to get access to acquisition during __init__ I'd like to hear about it John -- O5 Whewell's Ct, Trinity Coll., Cambridge CB21TQ (UK); T. 01223 355382

Hi All. Now, I want an explanation for this: zugang acl_users (Generic User Folder) [...] userList [...] this is the userList Method: <dtml-in "objectValues('seneka_user')"><dtml-var sequence-item> </dtml-in> BUT: this appears within the log file: ------ 2000-04-08T18:11:02 PROBLEM(100) GUF Attempting username/password validation ------ 2000-04-08T18:11:02 PROBLEM(100) GUF data is a string (['fred', 'jorge']) ------ 2000-04-08T18:11:02 PROBLEM(100) GUF data=['fred', 'jorge'] ------ 2000-04-08T18:11:02 PROBLEM(100) GUF User is None ------ 2000-04-08T18:11:02 PROBLEM(100) GUF Replacing response.unauthorized with our lo gin screen ------ (please notice that I inserted the "data=" debug info within the getUserNames-Method of GenericUserFolder.py Hmm... seems as though the olf fred and jorge appear over and over again. I flushed the cache, packed the dbase and switched between explorer and navigator (although this should not change anything). Restarted Zope, restarted computer, prayed, cursed I did about almost anything without success. Help or I will throw Zope to Hell. Regards, Ingo.

International characters and Catalog
by Vago Istvan 09 Apr '00

09 Apr '00

Hello, I just realized that catalog isn't index my Hungarian (latin-2) texts correctly. Searching the archive I found to use the -L switch starting z2.py . I done it, but with -L '' zope doesn't start up. Looking in z2.py I found z2.py imports the local module. The local module needs an other module: _local, but I haven't found it in my python installation. Do someone know how to get the file _local. Istvan Vago

Perhaps create a >folder in your ZClass, define permissions limits on it, create methods >inside that. Then when you want to be using content etc, just do ><dtml-with foldername>. Thanks John, I'd also already attempted that one too but, you know, even the folders can not have the "view" permission disabled within a class. eg. /Control_Panel /Products /MyProduct /MyClass /MyFolder /content [dtml-method] Again, clicking on the "define permissions" tab of MyFolder, it is not possible to disable the "View" permission. Perhaps it's just my installation (on NT) but it's a real pain. Thanks for the suggestion though. chas

Structured/location-directed publishing: Zope vs Zope-PTK
by Dennis Nichols 09 Apr '00

09 Apr '00

BACKGROUND: For the last 2 weeks I've been learning Zope so I can implement my current project using it. Just today, I looked at PTK for the first time since the day I discovered Zope. It seems to me that what I need falls halfway between just Zope and Zope-PTK. REQUESTING: Advice, or advice on how to get advice :-) A brief description of the project: Substantial content, structured in a conventional hierarchy but with often changing content: - 15 top level picks - 1-8 sublevel picks per top level - 1 to 100 pages per sublevel (sometimes with own substructure) - Navigation tree on left similar to Zope Manage interface - About 5-10 "special" content creators who can, in addition, create structure - Total of about 20 "regular" content creators - Need review of content before publishing Even more substantial unstructured content from other Members numbering x00,000 who can: - create content (may need review) in their own space - comment on content supplied by above content creators (may need review) - access web-based email - participate in forums (may need review) The "special" content creators, "regular" content creators, and other members should all use the same authentication/authorization system. None of the above seems particularly daunting to me -- given adequate time, I could construct it by coding and using various existing products on a Zope base or a PHP base. But the Zope base seems like the substantially better choice for this project. However, I don't know whether to turn down the PTK path or stick just with Zope (either way, I'm sure I'll use LoginManager). Zope-PTK wins at providing: - non-framed management interface w/ wizards - reviewing mechanism But fails entirely at: - supporting structured content Left to my own devices, I'd start working on structured content within the PTK. However, the background noted in http://lists.zope.org/pipermail/zope-ptk/2000-April/000562.html makes it unclear as to how to proceed. I also note that Nitin Borwankar in http://lists.zope.org/pipermail/zope-ptk/2000-April/000569.html is working on a similar (I think) task. All advice gleefully welcomed!!! -- Dennis Nichols nichols(a)tradingconnections.com

Fw: Embeding docs with dtml
by Carlos Neves 09 Apr '00

09 Apr '00

I've tried posting this on Zope-dev but had no feedback, so let's try here... ;) Hi, i'm trying to embed a dtml document in a child folder with a dtml method, like this: - I have a class wich defines the property "DocBase" - I have a dtml document called "DocTest1" in folder "Docs" - I set the "DocBase" to "Docs.DocTest1" Now, I need to call the contents of the document pointed by "DocBase" from a method. No hardcoding besides the name of the class and the name of the property... Several aproaches have been tried, with no luck :( Can anyone help on this eval() ---- Carlos Neves cneves(a)ruido-visual.pt

Uploads

09 Apr '00

Hi there, Is there a way to set up a page (a form in fact) that lets the user upload a file to the ZODB, in a specified directory ? I mean a user *not* being allowed to view the management screens. If somebody can direct me to read a guide or something, I'd really appreciate it. Dimitris Andrakakis http://atlas.central.ntua.gr:8000/~mc94068
