ZpdfDocument query
by Paul Smith 03 Oct '01

03 Oct '01

Dear all, I've installed the ZpdfDocument product, which works fine from the main management interface. I would like to be able to create ZpdfDocuments from calls from other methods, but using the syntax: <dtml-call expr="manage_addZpdfDocument(id='test',title='test')"> results in: Error Type: NameError Error Value: manage_addZpdfDocument Can anyone tell me if it is possible to do what I am trying to or any potential workarounds? Are their any more configurable methods of creating PDF documents from HTML out there that people can recommend? I've had a look at the various postings about ReportLab, but am not sure that will do what I need. My intention is that I can create a ZpdfDocument, which uses an existing method as the 'body'. I have edited the ZpdfDocument.py to do this so it works from the management interface (specifying the method ID to be used), but I would like to be able to do this as part of a process when creating other documents.

An accessrule in python script
by Gilles Lenfant 03 Oct '01

03 Oct '01

Hi, I wanted to improve the speed of my sites translating the DTML method accessrule into a python script. But when the DTML method works, the equivalent (?) python script doesn't (always show the default Zope page). Any clue ? Thanks in advance --Gilles ========My DTML method======== <dtml-let domaine="_.string.split(_.string.lower(_.string.split(HTTP_HOST, ':')[0]), '.')[-3:]"> <dtml-if "_['domaine']==['www', 'site1', 'com']"> <dtml-call "REQUEST.path.append('site1')"> <dtml-elif "_['domaine']==['www', 'site2', 'com']"> <dtml-call "REQUEST.path.append('site2')"> </dtml-if> </dtml-let> ========End DTML method======== ========My Python script ======== machine = _.string.lower(context.REQUEST.HTTP_HOST) servermap = { 'www.site1.com': 'site1', 'www.site2.com': 'site2' } if servermap.has_key(machine): context.REQUEST.append(servermap[machine]) return

OpenTicket for Zope
by Pieter Claerhout 03 Oct '01

03 Oct '01

Hello all, does anyone perhaps has a copy of the OpenTicket issue tracking system for Zope? I hoped secretly that there would be a download on the www.zope.org website, but it forwards me to http://openticket.point-one.net/ which seems to be completely down. Thanks in advance, Pieter

Deleting an object from python (command line)
by Gilles Lenfant 03 Oct '01

03 Oct '01

Hi, I made a buggy access rule at the root of ZODB that makes the ZMI unreachable (error in Python script) I want to delete this accessrule so I stopped Zope and... % cd $ZOPEROOT/lib/python % $ZOPEROOT/bin/python >>> import Zope >>> app = Zope.app() >>> dir(app) [..., 'accessrule',...] >>> app.manage_delObjects(['accessrule']) >>> dir(app) [...] # no more "accessrule" >>> ^D but 'accessrule' is STILL HERE ! When I do again : % $ZOPEROOT/bin/python >>> import Zope >>> app = Zope.app() >>> dir(app) [..., 'accessrule',...] # Thought it was deleted !!! Did I miss something ? Is there a "commit" like to do before quitting python? Thanks in advance --Gilles

nested records
by kosh＠aesaeion.com 03 Oct '01

03 Oct '01

Zope has a auto conversion ability on form data that I have been using a good bit however I am running into a problem. I have things nesting now and I need to nest the records zope is auto generating also so that items get dispatched to their correct objects. With just a single level foo.bar:record:type works well however what is the syntax for doing baz.bar.foo in a similar way where baz and bar are records and foo is a string/int/float etc. I tried baz.bar.foo:record:record:string and that didn't seem to work. Mainly I am seeking a dict of dicts approach when some of the dicts in addition to having their own pieces of data also have other dicts that they dispatch to their containing objects.

mysql auto_increment adding numbers on its own
by Ron Bickers 03 Oct '01

03 Oct '01

I have a ZSQL Method that uses MySQL's auto_increment and LAST_INSERT_ID() features to return the next order number. After my Python Script runs the zsql method to obtain the number, it proceeds to encrypt the order and updates the newly added MySQL record to include the encrypted text. This normally works okay, but somewhat regularly, and for no apparent reason, I end up with anywhere from 1 to 3 records in a row with auto_incremented numbers, but are null where there is normally the encrypted order. The orders are also e-mailed, and there has never been a case where an order was e-mailed and not inserted into the database, so it seems that *something* is causing MySQL to insert records on its own even when no order is being placed. Any ideas on why and/or how to prevent this? _______________________ Ron Bickers Logic Etc, Inc.

I just updated from Zope2.3.2/CMF 1.1 to Zope 2.4.1/CMF CVS, and on the whole it went smoothly. One problem which has cropped up is that when a user tries to change his or her password in CMF preferences, they get this error: Error Type: NameError Error Value: global name 'has' is not defined and the traceback: File /usr/local/zope/2.4.1/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/local/zope/2.4.1/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/2.4.1/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: LockableItem) File /usr/local/zope/2.4.1/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/2.4.1/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: change_password) File /usr/local/zope/2.4.1/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: change_password) File /usr/local/zope/2.4.1/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: change_password) File /usr/local/zope/2.4.1/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: change_password) File /usr/local/zope/2.4.1/lib/python/Products/CMFCore/FSPythonScript.py, line 187, in _exec (Object: change_password) (Info: ({'script': <FSPythonScript instance at 8acb520>, 'context': <CMFSite instance at 8c7e8e8>, 'container': <CMFSite instance at 8c7e8e8>, 'traverse_subpath': []}, ('Jarabeck', 'Jarabeck', []), {}, (None,))) File Script (Python), line 9, in change_password File /usr/local/zope/2.4.1/lib/python/Products/CMFCore/MembershipTool.py, line 355, in credentialsChanged (Object: portal_membership) File /usr/local/zope/2.4.1/lib/python/OFS/Traversable.py, line 233, in restrictedTraverse (Object: portal_membership) File /usr/local/zope/2.4.1/lib/python/OFS/Traversable.py, line 193, in unrestrictedTraverse (Object: ApplicationDefaultPermissions) NameError: (see above) Any ideas?

Problem passing parameters to a Python Script
by complaw＠hal-pc.org 02 Oct '01

02 Oct '01

I'm passing some paramters from an HTML form to a python script. I'm having trouble determining exactly which parameter is/isn't being passed to a python script. I get an error message saying "Zope Error" "Resource not found" along with a few troubleshooting suggestions -- but nothing else. Yes, I do know what the form is passing, and yes it does jive with the parameter list. Is something else going on? Is there a way to determine which parameter is causing the problem (i.e., get a more descriptive error message)? TIA, Ron

I just need to know how to change some things - > like move them around OK, that *might* work. But I think it will be very hard. I honestly don't know if you're ready to pull this off. ZPT is supposed to make it easier for a site designer to design stuff without caring how it works, while a site developer makes it work without caring how it looks. It doesn't magically enable you to avoid needing a developer if you need a developer. But CMF is supposed to let you set up a portal without being much of a developer. So in theory, it's possible to do what you want. In practice, CMF and ZPT have not been used together until recently and there just isn't any documentation of the sort you're looking for. You'll be pioneering a new technique, travelling in a hurry without a road map. I wouldn't want to be in your shoes. If you can look at a demo CMF site and imagine what you want each part to say, that's helpful. If you want something to *behave* slightly differently than how it does in CMF... that takes code. So here's what I suggest. It might be a long shot, but it might be worth a try. You need to customize a CMF skin. Skins exist to make it easier to change the look of a CMF site. Partly so users can select their favorite skin, but partly also to make it easier for you and me to create a new look. Unfortunately, what you need is a ZPT skin, and CMF doesn't come with one by default. You need the CMFDecor product. And that brings up another problem... You can currently only get the CMFDecor product (as far as I can tell) from CVS. You can browse it at cvs.zope.org, but to download you'll need a cvs program. Never heard of CVS? I suspect you don't have time for that now. Ask me and I'll mail you a copy of CMFDecor. Once you have CMFDecor in your zope Products directory, follow these instructions: http://cmf.zope.org/Members/teyc/skinPageTemplate/view That will set you up with all the skin ZPT files on your filesystem, so you can edit them there and not have to deal with WebDav or FTP or whatever. Changes you make should appear on the running zope site. I think. Be careful to keep an unmodified copy of CMFDecor around in case you screw something up by accident. Now, on the filesystem, look around in CMFDecor/skins. In particular, look in zpt_content, zpt_control, and zpt_generic. Most things you want are probably in zpt_generic. For example, main_template.pt is probably the one you care the most about. It changes how everything else looks: where the menus go and what they look like, etc. This template also makes use of a css stylesheet, zpt_stylesheet.css. actions_box.zpt is the box that shows your user name and any actions the user can take on the current page, like logging out, changing your preferences, etc. index_html.pt is the portal home page. I haven't figured out all the rest yet - I'm just looking at this stuff now. It's important to understand that with Page Templates, an individual page might not look like much when you edit it directly, but when you see it on a running Zope site it's getting wrapped in other templates (usually, in this case, main_template.pt). For example, if you look at index_html.pt directly in a browser, it doesn't look like much of anything. Hell, it's only 26 lines long. But it uses main_template, and then it displays the title of your portal, and the description you gave when you set up the portal, and then inserts news_box. If you can't manage to figure out which files correspond to which parts of the interface, you're f*cked I'm afraid. CMF is big, the ZPT skin is new, and there's not really any map that I know of that explains what it all does. You have to find out by reading the .pt files. So with any luck, you might be able to edit these templates in Dreamweaver and move things around on the page without breaking your portal. We can hope. -- ................ paul winkler ................ custom calendars: http://www.calendargalaxy.com A member of ARMS: http://www.reacharms.com home page: http://www.slinkp.com
