How to pass a dictionary object from PythonScript to DTML method?
by Dirksen 31 Jan '01

31 Jan '01

I have a Python Script 'test' to return a dictionary object, but these DTML statements can't retrieve that object: <dtml-let z="test()"> <dtml-var "z['b']"> </dtml-let> It reported a KeyError, Error value: 0. What goes wrong? Cheers Dirksen __________________________________________________ Get personalized email addresses from Yahoo! Mail - only $35 a year! http://personal.mail.yahoo.com/

Hi All Does anyone have info on how to use the new virtual hosting system with Zope 2.3.0, I had a little product that allowed me to quickly setup Virtual hosts under Zope 2.2.x using SiteAccess 2. But may product no longer works under Zope-2.3.0 Thanks ---------------------------------- E-Mail: Stephen Cimarelli <stephen(a)clari.net.au> Date: 31-Jan-01 Time: 12:50:28 ClariNet Internet Solutions +61 3 9486 0811 www.clari.net.au ----------------------------------

Hi all, The files found at http://www.zope.org/Members/sspickle/DumbZPatternsExample are not usable with Zope 2.3. Would it be possible to someone (Steve S. ;-) to update them ? Thanks a lot. -- Godefroid Chapelle BubbleNet 30, rue Victor Horta B-1348 Louvain-la-Neuve (Belgium) +32 (10) 45 06 46

How to display image returned from Catalog query
by Timothy Wilson 30 Jan '01

30 Jan '01

Hey everyone, I've got a PythonScript that returns a list of 'Photo' instances. I'm using <dtml-in returnPOTD size="1" orphan="0"> to grab the first instance off the list. What I can't figure out is how to display that image. I can use <a href="&dtml-absolute_url;"><dtml-var title></a> to make a link to the image, but I want this method to display the image directly. <dtml-var sequence-item> returns the instance itself and doesn't display anything. I'm sure there's something simple I'm missing here. Any suggestions? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.k12.mn.us/ | http://www.zope.org/ W.

DTML difficulties
by Nolan Darilek 30 Jan '01

30 Jan '01

I'm working on my first zope product and, while everything has gone relatively smoothly so far, I'm having some issues. The product is a folderish object which contains 3 subfolders, each of which contains a specific type of object. The structure looks something like this: work/: Main folder, UI, etc jobs/: List of all jobs projects/: taskforces/: Each folder contains a job, project or taskforce object, as well as the UI to manage them. Projects and taskforces are simple objects with names, descriptions, etc. Logic will be attached to these classes so that, when instances are viewed, they will search for jobs which are assigned to them. Each job can be assigned to multiple projects/taskforces. Now, the difficulty. I'm working on the UI for the job add form, which is in work/jobs. The form needs to iterate over the contents of projects/ and taskforces/, and I can't figure out how. Here's what I've tried: <tr> <th align="LEFT" valign="TOP">Taskforces</th> <td align="LEFT" valign="TOP"> <select multiple name="taskforces:list"> <dtml-in "PARENTS[1].taskforces"> <option value="<dtml-var id>"><dtml-var title_or_id</option> </dtml-in> </select> </td> </tr> <tr> <th align="LEFT" valign="TOP">Projects</th> <td align="LEFT" valign="TOP"> <select multiple name="projects:list"> <dtml-in "PARENTS[1].projects"> <option value="<dtml-var id>"><dtml-var title_or_id</option> </dtml-in> </select> </td> </tr> And the error I get is: | |Error Type: TypeError | | |Error Value: unsliceable object | Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: ESPWorkRequestAdd) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: ESPWorkRequestAdd) File /usr/lib/zope/lib/python/App/special_dtml.py, line 120, in __call__ (Object: ESPWorkRequestAdd) File /usr/lib/zope/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: ESPWorkRequestAdd) File /usr/lib/zope/lib/python/DocumentTemplate/DT_In.py, line 672, in renderwob (Object: PARENTS[1].taskforces) File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 617, in __getitem__ (Object: RoleManager) File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 257, in _getOb (Object: RoleManager) TypeError: (see above) Can anyone offer any advice?

LoginManager dlpierson example
by W. Robert Kellock 30 Jan '01

30 Jan '01

Hi, I'm new to Zope and I've been examining the LoginManager example given by dlpierson (http://www.zope.org/Members/dlpierson/sqlLogin) Although I am nowhere near understanding what it is doing, I'm very close to getting it to work - I think! It looks to me like I'm falling down in the PythonMethods (PythonScripts) in the Member ZClass. Are PythonScript arguments typeless? I keep getting an error Error Type: AttributeError Error Value: 'string' object has no attribute 'password' from the authenticate method which I'm passing self,password. Strangely following this error, I can hit the back button on my browser and reach the protected HTML page anyway! Here is the traceback. Your help would be appreciated.  ------------------------------------------------------------------------------------------------------------- W.Robert Kellock Ph: +64 3 326 6115 Sales Manager Fax: +64 3 326 6115 Credit Systems Control Ltd Web: www.creditscore.co.nz "making decisions easy" -------------------------------------------------------------------------------------------------------------

The new stylesheet used in the management interface
by Dominique.Dutoit＠cec.eu.int 30 Jan '01

30 Jan '01

I'm wondering if there's a document describing the use of the elements from 'manage_page_style.css' for unifying the management interface. Maybe it will be a good thing to release two DTML methods/documents to simulate the 'manage_page_header' and 'manage_page_footer' for backward compatibility with previous builds of Zope while moving to the new layout.

Problem with Cut and Paste
by Jerome Alet 30 Jan '01

30 Jan '01

Hi, First I'm sorry if this message was already received in this list, but I'm sure I've not received it to confirm, so I send it again, sorry for the inconvenience. I'm trying to modify OFS/dtml/main.dtml and OFS/CopySupport.py in order to create a shortcut button to cut an object and paste it in the parent object in one click, because I think this may save lots of boring clicks, at least for me. When I call the following method from the management interface (OFS/dtml/main.dtml) then I receive this error: "The data in the clipboard could not be read, possibly due to cookie data being truncated by your web browser. Try copying fewer objects." But when I call if from a PythonScript it works fine. My method, bound to a MoveUp button of my own: --CUT--- def manage_moveupObjects(self, ids=None, REQUEST=None): """Moves the selected objects to the parent objets (e.g. Folder)""" if ids is None and REQUEST is not None: return eNoItemsSpecified elif ids is None: raise ValueError, 'ids must be specified' if type(ids) is type(''): ids=[ids] if hasattr(self, 'aq_parent') and hasattr(self.aq_parent, 'manage_pasteObjects') : cb_copy_data = self.manage_cutObjects(ids, REQUEST) return self.aq_parent.manage_pasteObjects(cb_copy_data, REQUEST) ---CUT--- If I call self.aq_parent.manage_pasteObjects with None as the first parameter then it works fine from the management interface but not from a PythonScript: I receive a "No clipboard data found" error. Please could someone explain me what the problem is ? (I want it to work both from the management interface and from Python) Thanks in advance. Jerome Alet
