Re: [Zope] What the f... with bobobase_modification_time in a method of a ZClass ?

I posted this bug almost a year ago - http://classic.zope.org:8080/Collector/1709/view I'm afraid I've stopped worrying about it and taken evasive action to the extent that I don't even know if it's fixed in the current cvs. The above collector item is still pending. Dieter, like many people just might have given the anonymous role view permission in his root folder. Many others, like me, don't usually do that.

STX and images
by Danny William Adair 22 Aug '01

22 Aug '01

Hi! I want to be able to insert images in an stx document using the "alttext":img:/path/to/image input style of StructuredText.DocumentWithImages and then when needed render them to HTML using StructuredText.HTMLWithImages. For this purpose I tried to adopt code of the CMF that Tres Seaver posted to zope(a)zope.org (almost three months ago), to make it work as an external method that converts stx input (with the a/m image insertions) to html. I have the following code in my "Extensions" folder and the function stx_to_html (now available as an External Method) works _almost_ like a charm: --------------------------------------------------------------------------------------------------- import StructuredText, re from StructuredText.HTMLWithImages import HTMLWithImages _STXDWI = StructuredText.DocumentWithImages.__class__ class DWIClass( StructuredText.DocumentWithImages.__class__ ): _URL_AND_PUNC = r'([a-zA-Z0-9_\@\.\,\?\!\/\:\;\-\#\~]+)' def doc_href( self, s, expr1 = re.compile( _STXDWI._DQUOTEDTEXT + "(:)" + _URL_AND_PUNC + _STXDWI._SPACES).search, expr2 = re.compile( _STXDWI._DQUOTEDTEXT + r'(\,\s+)' + _URL_AND_PUNC + _STXDWI._SPACES).search): return _STXDWI.doc_href( self, s, expr1, expr2 ) DWIClass = DWIClass() class HWIClass( HTMLWithImages ): def document(self, doc, level, output): for c in doc.getChildNodes(): getattr(self, self.element_types[c.getNodeName()])(c, level, output) HWIClass = HWIClass() def stx_to_html( text, level=1 ): st = StructuredText.Basic( text ) if not st: return "" doc = DWIClass( st ) html = HWIClass( doc, level ) return html --------------------------------------------------------------------------------------------------- Problem is, as soon as I have an underscore in the image path, the rendering will stop at that point, and continue spitting out the rest of the URL as raw text. What am I doing wrong? Is it DocumentWithImages or HTMLWithImages themselves, or is it the above subclass (with _URL_AND_PUNC) that lead to this incorrect rendering? (btw, Zope Version is 2.4.1b1) Thank you very much in advance, Danny

Where did the add users button go?
by Chris Beaumont 22 Aug '01

22 Aug '01

Hello all.. Its been awhile since I have added a new user, and now I need to add one.. But...when looking, the add users button is gone.. So basically, I'm at a loss to figure out where the add user button in my various acl_users folders is. Is this a bug or a feature? I've tried logging in as myself (the owner of all of the site, Zope-wise) as well as as superuser and that doesn't change anything.. The buttons are gone in both of the Zopes I am using.. This must be a very simple thing.. what am I doing wrong? Am I looking in the wrong place? Zope versions are 2.2.4 and 2.3.3 TIA, Chris

22 Aug '01

Hi all, Has anyone be able to use Cache-Control from Zope? I've tried both of the following headers (the later one for IE5.5) but I a new DateTime each time. Maybe it's just my browsers (IE5.5 and Netscape® Communicator 4.75) DTML-Method: <dtml-call "RESPONSE.addHeader('Cache-Control','max-age=100000')"> <dtml-call "RESPONSE.addHeader('Cache-Control','post-check=100000, pre-check=50000')"> <html><body> <pre> <dtml-var "_.DateTime()"> </pre> </body></html> Catched output from ZPublisher.Publish.py (publish): HTTP/1.0 200 OK Server: Zope/Zope 2.3.3 (binary release, python 1.5.2, win32-x86) ZServer/1.1b1 Date: Wed, 22 Aug 2001 23:06:15 GMT Connection: Keep-Alive Content-Type: text/html Content-Length: 259 Cache-Control: max-age=100000 Cache-Control: post-check=100000, pre-check=50000 <html><body> <pre> 2001/08/23 01:06:15.01 GMT+2 </pre> </body></html> Regards, Johan Carlsson

Quick question about traversal...
by Rob Foster 22 Aug '01

22 Aug '01

I've created a product with a zclass. In the zclass I've got a python script that returns a simple list. I'm trying to use that list in a dropdown menu that that is part of a dtml document off the root, i.e. /somefolder/dtml_document I can't seem to traverse to said script. Any ideas would be appreciated. Thanks, Rob

I have tried it. And I have tried another ways. But nothing. I have been today two hours making and thinking different ways. My last try is find someone who can make the query without problems in this list. Farrell seems to be. But in RedHat. Tomorrow I´m going to write and specifie all the products version data and OS used(It´s Linux, but I can´t remember now more). Thanks again. Jim Antonio Carrasco > > > Also, I worry about Departments. PostgreSQL is case sensitive. > You are sure it is created as Departments and not departments?

Images from database into html
by Sven Syld 22 Aug '01

22 Aug '01

Hello, I have gained access to a employees' database which among other stuff contains employees' photos (that is, in binary form). I'm trying to display employees with their names and photos etc. To this moment I have figured out only one solution (which does not work). HTML page looks like this: <dtml-in sql_employees> <dtml-var first_name> <dtml-var last_name> <img src="his_or_her_photo"> (which is DTML method) <br> </dtml-in> DTML method his_or_her_photo: <dtml-call "RESPONSE.setHeader('Content-Type','image/gif')"> (just in case, but this apparently has no effect) <dtml-var photo> Since his_or_her_photo is under sql_employees it should return person's photo. I understand that problem is that src inside <img> isn't rendered by Zope but by browser? Any hint would be appreciated. Sven Süld

too many arguments TypeError problem
by Peter Bengtsson 22 Aug '01

22 Aug '01

Consider this class class CImageObject(Photo.Photo): def tag(self, REQUEST=None, display=None, pdcookie=None, height=None, width=None, alt=None, **args): print "proof that CImageObject is the class used" [...my magic on top of Photo...] # the below line is line 48 Photo.Photo.tag(self,REQUEST, display,pdcookie, height,width,alt,args) The Photo class is the Photo product. The tag function looks like this: def __call__(self, REQUEST=None, display=None, pdcookie=None, height=None, width=None, alt=None, **args): " bla bla bla " tag = __call__ My class is called from DTML like this <dtml-var "an_image.tag(border=1,alt='',width=9)"> That's when I get the strange error: Error Type: TypeError Error Value: too many arguments; expected 7, got 8 (Object: tag) File C:\Program Files\zope\lib\python\Products\n4a\medialibrary_zb\medialibrarydata.py, line 48, in tag (Object: 200110.jpeg) TypeError: (see above) If you count them, they match like they should. Our class used to subclass the Image product before, in which's tag() method also has 8 arguments. Does anybody know what's going on? Cheers, Peter

Problems starting zope
by Dirk Becker 22 Aug '01

22 Aug '01

Hi all, I want to restart zope, but I have some problems doing this. I triet to extend zope in this way, that I can make a databaseconnection to a MySQL-database. For this I used ZMySQLDA-2.0.7.tar.gz. After unzipping this file and installing the database-interface I was able to restart zope, but it was not possible to add an databaseconnection to my website, I'm building up in zope. I removed the folder that was created by unzipping the ZMySQLDA-2.0.7.tar.gz-file and tried it with the version ZMySQLDA-2.0.6.tar.gz, because this version was recommended in a book I've read. Then I tried to restart zope, but I got the following error-message: [1]3845 pengine:/opt/zope-current # Traceback (innermost last): File "/opt/zope-current/z2.py", line 548, in? zdaemon.run(sys.argv, os.path.join(CLIENT_HOME, Zpid)) NameError: CLIENT_HOME [1]+ Exit 1 I don't know very much about zope and its technology, so I hope that someone can help me, to solve my problem
