You have not said wither the probem is a mal-formed image tag, or the image tag failing to fetch the image. Also, pay attention to Tino's comments on seurity. I only ever use a Serial Number, not Filename - that comes from a database. Don't forget that image tags should have width, height and alt attributes.

Programatically setting advanced settings in zsql methods
by Jeff Gentry 06 Apr '05

06 Apr '05

Hello ... I have a python based product where I am creating a few zsql methods at the time of instantiation. I recently realized that there is the default 1000 row maximum limit on query rows. While this can be changed through the management interface, I am trying to figure out how to do this when I create the SQL method in the python code. Is this possible? Thanks -Jeff

CMFSin time errors
by MILLER Eva 05 Apr '05

05 Apr '05

Hi, I'm getting some errors with certain feeds, but not others, in CMFSin. The errors seem to have something to do with the portaltime and localized time. Someone suggested changing the permissions for anonymous to fix this. Doing that made all my feeds malfunction, so that's not the right answer. I know CMFSin is old and it seems to be getting flaky. But I really need an aggregator for my project, and it doesn't seem like there's anything much better out there right now. Here's what happens when I use a feed from National Public Radio (http://www.npr.org/rss/rss.php?topicId=3) I know the feed is working. CMFSin's debug panel shows the results of the feed very plainly. The problem is in the display of the feed (which is either Zope or Plone's fault, though I can't tell which right now): Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 306, in __call__ Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec Module Products.CMFCore.FSPageTemplate, line 191, in _exec Module Products.CMFCore.FSPageTemplate, line 124, in pt_render Module Products.PageTemplates.PageTemplate, line 96, in pt_render - <FSPageTemplate at /plinkit/sinList used for /plinkit/interestsideas/headlines> Module TAL.TALInterpreter, line 190, in __call__ Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 671, in do_useMacro Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 409, in do_optTag_tal Module TAL.TALInterpreter, line 394, in do_optTag Module TAL.TALInterpreter, line 389, in no_tag Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 702, in do_defineSlot Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 409, in do_optTag_tal Module TAL.TALInterpreter, line 394, in do_optTag Module TAL.TALInterpreter, line 389, in no_tag Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 650, in do_defineMacro Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 694, in do_defineSlot Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 409, in do_optTag_tal Module TAL.TALInterpreter, line 394, in do_optTag Module TAL.TALInterpreter, line 389, in no_tag Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 613, in do_loop_tal Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 637, in do_condition Module TAL.TALInterpreter, line 234, in interpret Module TAL.TALInterpreter, line 484, in do_insertText_tal Module Products.PageTemplates.TALES, line 227, in evaluateText Module Products.PageTemplates.TALES, line 221, in evaluate - Line 35, Column 92 - Expression: <PythonExpr here.toPortalTime(obj['date'])> - Names: {'container': <PloneSite instance at b5c87740>, 'context': <PloneFolder instance at b2d87d40>, 'default': <Products.PageTemplates.TALES.Default instance at 0xb69758cc>, 'here': <PloneFolder instance at b2d87d40>, 'loop': <SafeMapping instance at b2b685d0>, 'modules': <Products.PageTemplates.ZRPythonExpr._SecureModuleImporter instance at 0xb696ed8c>, 'nothing': None, 'options': {'args': ()}, 'repeat': <SafeMapping instance at b2b685d0>, 'request': <HTTPRequest, URL=http://demo.plinkit.org/interestsideas/headlines/sinList>, 'root': <Application instance at b5c87710>, 'template': <FSPageTemplate at /plinkit/sinList used for /plinkit/interestsideas/headlines>, 'traverse_subpath': [], 'user': Anonymous User} Module Products.PageTemplates.ZRPythonExpr, line 47, in __call__ - __traceback_info__: here.toPortalTime(obj['date']) Module Python expression "here.toPortalTime(obj['date'])", line 1, in <expression> Module Products.CMFCore.FSPythonScript, line 104, in __call__ Module Shared.DC.Scripts.Bindings, line 306, in __call__ Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec Module Products.CMFCore.FSPythonScript, line 160, in _exec Module None, line 5, in toPortalTime - <FSPythonScript at /plinkit/toPortalTime used for /plinkit/interestsideas/headlines> - Line 5 Module Products.CMFCore.FSPythonScript, line 104, in __call__ Module Shared.DC.Scripts.Bindings, line 306, in __call__ Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec Module Products.CMFCore.FSPythonScript, line 160, in _exec Module None, line 4, in toLocalizedTime - <FSPythonScript at /plinkit/toLocalizedTime used for /plinkit/interestsideas/headlines> - Line 4 Module Products.CMFPlone.PloneUtilities, line 118, in localized_time Module DateTime.DateTime, line 522, in __init__ Module DateTime.DateTime, line 745, in _parse_args Module DateTime.DateTime, line 1032, in _parse SyntaxError: Tue, 05 Apr 2005 14:21:06 EDT Thanks, Eva Miller, Librarian

That's a bit too much to say... I used 2.6 packages back in 2003 and until Debian decided to support multiple instances in its 2.6 packages everything worked fine. Thus I installed 2.7 in my home when I restarted my work on the website... I just had an argument on debian-user-german with somebody who basically said "why does Plone state it's easy to install and works out of the box, when it doesn't". He tried with apt-get install plone and after some forth and back I decided to try it out myself and found that he just didn't read the debconf-message. So it's basically only the installation experience, nevertheless this was really good - I seldom find such messages in a debconf during installation of a package. The normal case from my experience is that the maintainers just expect the user to go to /usr/share/doc/<package> and read README.Debian. > If you're interested, take a look at I'm not working with Zope anymore, I'm not even working on those websites anymore... > | This will probably change when > | Debian finally drops zope26 > > Or when people finish organizing and implementing a way to support > multiple versions of zope (which, IMO, is necessary). I think the 2.6 and 2.7 packages in Debian can quite good coexist, I mean if you're using those 3 extra product-lines in the conf of zope2.7 and install all the new Products (that don't work with zope2.6) into the instance-home it shouldn't be much of a problem. Of course there coud be a problem with those FileSystem-Products that store the data in the filesystem, you probably cannot share those with the 2 versions, but then it's still easy to have a copy of the product-folder for each version of zope... > | (I don't understand why they keep it > | anyway...) > > I believe they keep it just because it is already there and we are > near a stable release (and there is no immediate path to safely drop > it). More-or-less the same reason python 2.1 and 2.2 are still in > debian (but won't be in etch). Ok, I guess I did not get that there was no zope maintainer for a long time. Because Zope2.7 is not there since some months (I mean upstream), but for a rather long time... > People who are currently using 2.6 will need 2.6 in sarge when it is > released, and they'll also need 2.7 so they can work on migrating. > Then 2.7, 2.8 and 3.1 will need to co-exist so people can migrate from > 2.7 to one of the others and so that individual projects/sites can be > migrated independently (without needing new hardware or installing > from source). Maybe I'm just to used to installing from source, but for upgrading purposes I would still do it with the source package... I tried to upgrade the 2.6 instance with the debian 2.7 package, but I messed up. Doing it with the source package was somehow easier - even though this probably wasn't a problem of the packages themselves, but of my knowledge (or better the lack of). Then I read the zope-ml's and found that a common advice is to use the source packages... So far for my story, and I do think the debian packages for zope are quite good (as debian packages are in general ;-) > PS - did you mean to continue this discuss off- list? Did I? I don't think so, but maybe you set a header that caused my mutt to do a CC - anyway the fcc-hook for the mail was active, so I don't have a copy of it anymore (ML-mails go to /dev/null here). I'm putting it back on list now.

Set MIME type using ZPT
by srikanth 05 Apr '05

05 Apr '05

Hi, I am using an external method to load an Image from the harddrive. The external method is as follows: from email.MIMEImage import MIMEImage ##parameters=filename def getDocument(filename): fname = '/mnt/'+filename; input = open(fname,'r') content = MIMEImage( input.read( ) ) input.close( ) return content When I try to display the content in the webpage what I actually got is all raw data of the file rather the image. So how can I convert the raw data to be dispalyed as image in the webpage. I am using ZPT to display the web page (image). If its dtml I could have used <dtml-mime> tag is there any equivalent to that in ZPT. Any suggestion would be a gr8 help. Ta.
