doActionFor

Im having trouble auto-publishing objects. In the content_submit_form after checking that the object should be auto published i have these lines. <dtml-call "portal_workflow.doActionFor(this(), 'publish')"> <dtml-call "RESPONSE.redirect('view?portal_status_message=Status+changed+to+published')"> This works fine for "Manager" but if a "Member" tries to do it it generates an unauthorized() error message. I even put a proxy role of Manager on the content_submit_form script but i still get the error. How can i accomplish this? __________________________________ Do you Yahoo!? Yahoo!

Re: importing pdflib_py
by Blossom Merz 23 Jan '04

"You don't need to be helped any longer. You've always had the power to go back to Kansas..." OK, so we don't need to make a custom Product or anything like that to use an external library in a Script. It's just a simple (!) matter of semantics. BAD: from pdflib_py import * GOOD: import pdflib_py or from pdflib_py import PDF_new, PDF_open_file, PDF_get_errmsg, [...] I guess the security machinery just wants to be sure that you know exactly what you're importing. Maybe they're trying to prevent name conflicts or something? Or maybe the external library won't give up its list of methods. Whatever. I'm back to work after my little visit to Oz. blossom

mail encoding problem
by Ronny Theunissen 23 Jan '04

23 Jan '04

I'm trying to send a mail from Zope (2.6.2b3 on RH9.0) containing latin-1 characters using the following script invocations: # external method to quopri.encodestring encode=container.encode_quotedprintable container.MailHost.send(encode(body),mto=toAd,mfrom=fromAd,subject=encode(subject),encode='quoted-printable') This works fine for the Yahoo mail-client, but Outlook filters out special characters in subject and body. Does anyone know a solution to this problem?

Re: [Zope-dev] help me convert from j2ee to zope

Hi Ryan, The zope-dev list for the development OF zope, not WITH it, so I'm replying to the more appropriate zope(a)zope.org list...

That might not be necessary, but there's nothing wrong with it ;-) > What kind of naming service is available within Zope? For example, how can I > get a reference to one object from another object within Zope? All objects are refered to by their paths in the ZODB.

This made no sense to me as a Zope developer, and it's YEARS since I did anything EJB'ish. I suggest you try and present the problem you're trying to solve, rather than trying to bash square JBoss concepts into a round Zope hole... > How can I create new objects programmatically in Zope?

If you're doing everything as Python Products, then you write a construction method, usually called manage_addMyThing, import that where you want to create your object, and then use it: from MyProduct import manage_addMyThing ... manage_addMyThing(afolder,'new_id',...any other needed parameters...) > Are there any other gotchas that ex J2EE developers can tell me about > switching to Zope? Yeah, Zope is not J2EE. Trying to think in J2EE terms and make those concepts work in Zope will only lead to pain and suffering for you and anyone who tries to help you ;-) > I've read all the documentation I can find on the web site, I doubt that ;-) Zope Book? Zope Developers Guide? ALL the How-To's and examples? The website is difficult to navigate, and I apologise for that, but the stuff is on there... cheers, Chris

thanx for your reply, your reply made me test my script again . then, I realized I got problem when i used 'return' command. i test this script which outlines this problem : script: homeFolder = context for n in names_containers: h = str(context.ZopeTime().strftime('%S')) rep = '%s-new-%s' % (n,h) if not hasattr(homeFolder, rep): homeFolder.invokeFactory(type_name='Folder container', id=rep, title=n) return printed ... it runs well with Mozilla .... but .... the problem comes back with konqueror - when there is a return string, konqueror ask for openning a text viewing program which reposts the initial request again (if I click on 'Open' ) ! >On Tue, Jan 20, 2004 at 05:47:00PM +0100, francois wrote: >> hello, >> I got a problem with copy container support. >> I'm trying to use manage_copyObjects() and manage_pasteObjects() to migrate my >> old Zope member folders into new folders. >> I copied all content of the old folder, I created a new folder and I pasted >> the clipboard in. but my problem is, zope duplicate the object in the new >> folder : for example if i got a file object with 'zz' id in the first >> folder , Zope give me in the new folder : 'zz' .. and 'copy_of_zz'. > >That will happen if you run this script more than once. >I didn't spot anything wrong with it. > >-- > >Paul Winkler >http://www.slinkp.com >Look!

SQLForms and DEC()
by Stephan Goeldi 22 Jan '04

22 Jan '04

I create a mysql table using SQLForms. Everything is fine, except one problem: I'd like to create a field as decimal(7,2). But in SQLForms I have only the choice of INT or FLOAT. When I try FLOAT, the input of e.g. 375.5 or 375,5 gives me this error message: Error Type: TypeError Error Value: not enough arguments; expected 3, got 2 The same I get if I create the table by hand using field type decimal(7,2). Does anybody know what the problem is?

help with pygantt
by Aruna Prabhakaran 22 Jan '04

22 Jan '04

hi all, I am working on an application wherein I need to generate gantt charts using pygantt tool . When I run the script from the python shell prompt, it is working fine, but raises an error when i try to do it in Zope (using Zope 2.7 and python 2.3.2) I get the following traceback : ------------------------------------ Traceback (most recent call last): File "/usr/local/bin/pygantt", line 4, in ? run(sys.argv[1:]) File "/usr/local/lib/python2.3/site-packages/logilab/pygantt/main.py", line 110, in run output.write(r.render(proj)) File "/usr/local/lib/python2.3/site-packages/logilab/pygantt/renderers/renderer.py", line 339, in render AbstractGanttRenderer.render(self, project) File "/usr/local/lib/python2.3/site-packages/logilab/pygantt/renderers/renderer.py", line 61, in render self.open_table(project) File "/usr/local/lib/python2.3/site-packages/logilab/pygantt/renderers/renderer.py", line 390, in open_table self._h.init_drawing(width, height) File "/usr/local/lib/python2.3/site-packages/logilab/pygantt/renderers/PILHandler.py", line 71, in init_drawing self._default_font = load_font() File "/usr/local/lib/python2.3/site-packages/logilab/pygantt/renderers/PILHandler.py", line 60, in load_font return ImageFont.load(os.path.join(FONT_DIR, font_name)) File "/usr/local/lib/python2.3/site-packages/PIL/ImageFont.py", line 166, in load f._load_pilfont(filename) File "/usr/local/lib/python2.3/site-packages/PIL/ImageFont.py", line 76, in _load_pilfont raise IOError("cannot find glyph data file") IOError: cannot find glyph data file ------------------------------------------------------------ Can somebody throw light on this?
