ZOPE and Slackware
by jiva＠devware.com 01 May '00

01 May '00

This is SLIGHTLY off-topic, but I'm trying to get Zope installed on Slackware Linux 4.0 In order to do this, I need to compile python 1.5.2 and get it running on there. I've done this, and I start up zope and it croaks on the time.daylight attribute. (it doesn't exist) Here's the stack dump: File "/usr/local/Zope-2.1.6-src/ZServer/medusa/http_server.py", line 746, in ? tz_for_log = compute_timezone_for_log() File "/usr/local/Zope-2.1.6-src/ZServer/medusa/http_server.py", line 729, in compute_timezone_for_log if time.daylight: AttributeError: daylight And checking this just using python, I get: >>> import time >>> time.daylight Traceback (innermost last): File "<stdin>", line 1, in ? AttributeError: daylight >>> This does NOT occur under RedHat (which I am more familiar with, but I have to use slackware in this case). Can anyone tell me what parameters I have to compile python with to get the time.daylight module to work? Jiva -- If at first you don't succeed, try, try again. -- W.E. Hickson

manage_clone issue

I've got a nice (!) ArtClass, subclassed from ObjectManager. I'd like to create an instance of ArtClass that contains a few Images, then (eventually) delete the Images. I get the following: ! The object MVC-009F.JPG does not support this operation [...] File /usr/lib/zope/lib/python/OFS/CopySupport.py, line 284, in manage_clone (Object: art_1) File /usr/lib/zope/lib/python/OFS/CopySupport.py, line 374, in _verifyObjectPaste (Object: art_1) Copy Error: (see above) This is the code: def NuovoArticolo(self,REQUEST,RESPONSE): r='' group = REQUEST.form.get('group') # list of images to be added next_art = self['next_articolo'] # next article ID: property of this folder upload = self.upload.this() # upload folder contains the images id = 'art_%s'%next_art newob=upload.Control_Panel.Products.MArticolo.ArtClass(id) newob.id=id upload._setObject(id,newob) r=r+ 'Articolo %s aggiunto.' % next_art next_art = next_art + 1 next_foto = self['next_foto'] # next image ID for i in group: newob.manage_clone(upload[i],'foto_%s'%next_foto) newob[next_foto].manage_changeProperties({'filename': i}) # store old filename next_foto = next_foto + 1 self.manage_changeProperties({'next_articolo': next_art}) self.manage_changeProperties({'next_foto': next_foto}) return r What am I doing wrong?

IE Auth failures, NS works fine
by JB 01 May '00

01 May '00

Please excuse my ignorance in this matter. I know nothing about Windows. I have posted this before but have had no luck with a solution. I thought one more try here and then I guess I migrate to Enhydra or something. Anyway, I have a site with about 300+ users running on Redhat 6.1 with Apache serving Zope. Auth is handled by GUF, but I don't think GUF is an issue. I've been fielding problems authenticating with Internet Explorer for about a month now. The solution? Use Netscape. It works perfectly. I don't think this is very acceptable, however. Can't anyone help me track this down? I have no idea where to start looking in Windows to figure this out. I have no idea what questions to ask. Why is a browser not a browser? TIA jim

RE: RE: [Zope] Acquisition problem
by Andreas Wacknitz 01 May '00

01 May '00

Hi, the problem I originally mentioned is more simple: Root = Zeilenfarbe | + - index_html | + - Folder1 = Zeilenfarbe | | | + - index_html | + - Folder2 | + - index_html Within index_html I use Zeilenfarbe to set the backgraound color of odd table rows: ... BGCOLOR="<dtml-var Zeilenfarbe>" ... What I expect is: - Root's index_html renders Root's Zeilenfarbe - Folder1's index_html renders Folder1's Zeilenfarbe - Folder2's index_html renders Root's Zeilenfarbe BUT: Folder1's index_html renders Root's Zeilenfarbe. If I drop Root's Zeilenfarbe Folder1's index_html will render it's own Zeilenfarbe (and Root's and Folder2's index_html will raise errors). Andreas

Acquisition problem
by a.wacknitz＠francotyp.com 01 May '00

01 May '00

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am a little bit confused as acquisition does not work as I expected it would. I have assigned a property named Zeilenfarbe (to the top level folder). Zeilenfarbe is used to set the background color of odd rows in tables. When I assign a property with the same name (and other content) to a subfolder the rows are colored with the color defined at top level. If I remove the property at top level I will get the expected row colors. So what is wrong here?

Re: [Zope] tree-tag & SQL - works not properly with zope2.1.6
by Andrew Williams 01 May '00

Philipp: I am running Zope 2.1.6; here is how I have my tree stuff setup (now that I'm in the office and can look at my code): Database: ---------- Objectid as String, Primary Key Parentid as String --------- SQL Method: ------------ Name: q_associativeprimary Arguments: parentid Query parameter: select objectid from t_associativeprimary where <dtml-sqltest parentid type=string> ------------- DTML Method: -------------- <dtml-let objectid=platformadmin> ...html stuff... <dtml-call "FSSession.set('pa',platformadmin)"> <dtml-tree id=objectid branches_expr="q_associativeprimary(parentid=objectid)" leaves=q_results_dtml urlparam="pavar=1"> <B><dtml-var objectid></B> </dtml-tree> ...more html stuff.. </dtml-let> --------------- q_results_dtml simply uses the objectid to lookup some values in the database and display them. Everything works good for me. The tree is displayed and expand_all and collapse_all works (I patched treetag.py). The only thing which doesn't happen is expand_all doesn't expand the leaves. When I get a chance, I'm going to look into that part. Hope that helps...

ANN: JPicture 0.0.2 released
by Jens Vagelpohl 01 May '00

01 May '00

Hi everybody, Having read a lot of peoples' questions about how to create types of objects that act as a container and into which you can upload stuff like pictures, and because I had a personal need for this type of object, I sat down and created "JPicture". I know, very imaginative name... JPicture is an "old-style" Zope product (meaning it is not ZClass-based and all components are on the file system) that is based on Zope's own Image class with the following additions: * a field of type "text" called "description" that allows you to store more than just a title with the picture * a second image can be uploaded into a JPicture as a "thumbnail" attribute. This can be done either when a JPicture is first created or at any point afterwards. Otherwise JPicture quacks and waddles just like a normal Image in Zope. Apart from my own need I hope it can serve as a model for those who have had problems in the past tackling the "uploading a file into an object"-problem. And if you're a big ZClass fan it is very easy to make JPicture into a Base class that can be inherited by a new ZClass by either replacing the code in __init__.py that starts with "context.registerClass..." with a line that reads "context.registerBaseClass(JPicture.JPicture, 'JPicture') or simply adding this after the "context.registerClass..." bit.

Re: [Zope] tree-tag & SQL - works not properly with zope 2.1.6
by Andrew Williams 01 May '00

Try this: SQL Method: ----------- Name: itemquery Arguments: parentID Query: SELECT item.itemid FROM item WHERE <dtml-sqltest parentID type=int>; ----------- DTML Method: ------------ ...stuff <dtml-let ItemID="-1"> <dtml-tree id=ItemID branches_expr="itemquery (parentID=ItemID)"> <a><dtml-var ItemID>:  <dtml-var name></a> <br> </dtml-tree> </dtml-let> ...more stuff ------------ It looks like your SQL-Query is where the problem is: where parentID=<dtml-var parentID> when called by the dtml-method is basically going to be where parentid=parentid which is a circular reference. If you change the sql statement to the one above, then sql- method will evaluate out to: where parentid=item which is what you want. Hope this helps.
