root level referencing + minimalist zope strategies
by Jason Cunliffe 25 Oct '99

25 Oct '99

Hello Sorry if this has been covered before, but if it was I have missed it. [note: I get the digest and find that about for about 1 in 5 digests the formatting becomes illegible 2/3 of the way down] I am still looking for advice and strategy tips for this basic situation: I have sub-folders called 'images' in my site where only graphics for those contexts are kept there. I also have a top level folder called 'images' where to store navigation bar graphics, company logo, etc. / /images /folder1 /images /folder2 /images /folder3 --no images folder here yet a simplified basic standard_html_footer looks like this: <p> <a href = /> <dtml-var "images.logo.tag(border=0, alt='Go to Top Menu')"> </a> </BODY></HTML> This is acquired by folders below root level. This works fine everywhere index_html calls standard_html_footer where there are no local subfolders named 'images'. I can of course 'fix' this by implementing local standard_html_footer methods in the subfolders. But I want a cleaner, minimal, more zopish way to automate the folder level awareness. I've almost 'got it' about the namespace stuff... I have tried tweaking the method above by adding <dtml-with /images> or <dtml-with "/images"> - but that's wrong... 1. What site wide logic to install for this? 2. In general, how do you reference the root level "/" with the various forms: <dtml-var> or <dtml-in> or <dtml-with> <dtml-let> ?? 3. I want to set a variable "myelevel" using for example <dtml-let mylevel = /refrences/new">. So that I can then call: <dtml-var mylevel.images.newlogo> Thanks. - Jason ------------------------------------------------- Jason Cunliffe <jasonic(a)nomadicsltd.com> NOMADICS.STUDIO(Design Director) Geo-Digital Arts and Technology Le Vieux Moulin, Route de Mons 83440 SEILLANS, FRANCE Tel: +33 (0)4 94.76.98.72 Fax: +33 (0)4 94.76.97.77 <jasonic(a)nomadicsltd.com>

25 Oct '99

Hi all, I've managed to get PIL working with Zope on win32 and now need some fonts. I took some PCF(?) files from a Linux box and converted them but PIL barfs when trying to use them. My question is whether anyone has some fonts that definitley work with PIL(win32)? TIA Phil phil(a)wigwamweb.net

Q: How to check if Image exists (inside REQUEST object)?
by Samu Mielonen 25 Oct '99

25 Oct '99

I have another (for me) tought nut to crack and would appreciate any help: I'm handling a submit-form (now in multi-part/formdata :) with a method called postit (from KMNetNews). I'm trying to detect within postit whether an image was included in the image1 property of the submit form (i.e. did the user decide to upload an image with the <input type=file name=image1> button): I.e. my hierarchy: ../../uniqueID - folderish article object edit - the submit form postit - the method that receives submit form data Inside postit I check: <dtml-if "image1"> The above always returns true, regardless of whether I've submitted an image via the edit-form or not. Same for: <dtml-if image1> <dtml-if "REQUEST.image1"> <dtml-if "_.str(REQUEST.image1)"> <dtml-if "_.str(REQUEST['image1'])"> <dtml-if "not _.str(image1)==''"> they always return TRUE regardless of whether I submitted an image via the submit's form image1 property. Furthermore: *<dtml-var image1>* returns: ** i.e. a null/empty/none contents! I tried to get the get_size, size and getSize methods to work with the image object*, but I always got an AttributeError, so I couldn't do the checking via size either. * as a matter of fact, I'm not sure image1 is an image object, if no image was included in the submit form? I also tried forcing the image1-property to an actual data type through HTML, in case no image was specified for uploading: <input type=file name="image1:boolean" value="off"> ... and tried to check with that too, but that didn't help either. I always get TRUE, whatever I do. So, how can I check whether an image was submitted or not? I'm beginning to sucpect I've misunderstood something gravely. Best regards, Samu Mielonen PS Once again I scoured the mailing list archives, but found no references to this problem. My apologies, if this is a trivial question or a faq. -- "Our reflections on the order of society, as well as nature, are still dominated by the Newtonian image of massive power, exerted by sovereign agency through the operation of central force..." -Stephen Toulmin, "Cosmopolis"

How to pass parameters to a DTML Method from within another DTML method?
by Hunter Kelly 25 Oct '99

25 Oct '99

I'm trying to pass parameters to a DTML method when calling it from another DTML method. I've tried stuff like <dtml-var "anotherMethod(foo='blah')"> but it seems to totally screw up the namespaces. Anyone have any thoughts? Thanks, Hunter

Tree tag
by Katrin Kirchner 25 Oct '99

25 Oct '99

Hi everybody! I'm having a problem with the tree tag. I have a page where I want to show all postings of 7 Confera Topics. So far I can show the different trees of the Topics but the page raises an error message when I want to expand any of the trees. Therefore I want to show the page with the trees already expanded. But whatever I tried, the trees aren't shown expanded. I've tried the following commands:   and I've tried to put expand-all or expand_all in the tree tag. But nothing worked. When I try to put expand-all in the tree tag, it says it's not a valid argument. Is there anyone who can tell me how to have the trees shown expanded? Thanks in advance Katrin

RE: [Zope] Could someone translate the debugging information?
by Jeff Rush 25 Oct '99

25 Oct '99

Actually I've seen the error about not having access to Z2.pid occur for reasons other than file permissions per se. It appears that the PCGI daemon still has the code in him that detects whether the zserver process is running and if not, he starts one. Nowadays zserver is started via ./start or /etc/rc.local but if it should fail for some other reason, or if the PCGI control file (Zope.cgi) is not correct, the PCGI daemon will spawn zserver, but with the -wrong- ownership/permissions. I tried to disable that part of PCGI when I built the RPMs but could not find an (easy) way. I figure it won't matter soon when FastCGI is released and we move away from PCGI. I swear though, that the Z2.pic problem is the -most- commonly reported failure w/Zope that I in my email box, and made worse that often it is a red herring. The other one I see, for the same reasons is: ImportError: (<class exceptions.IOError at 80a3008>, "[Errno 13] Permission denied: '/var/zope/var/Data.fs.lock'") To demonstrate the problem, run Zope in PCGI+ZServer mode, start up Zope and show that it works fine. Now, kill -9 both the zdaemon and zserver processes, and tell your browser to display a Zope page. Wait 15-60 seconds, while PCGI starts a new zserver process, and whamo, one of the above error messages will appear in your browser window, with a traceback in the HTML source as usual. I didn't *touch* the file/dir permission settings between the successful and unsuccessful test. Very misleading... -Jeff Rush On Sun, 24 Oct 1999 12:37:47 -0400, Michel Pelletier wrote: >> -----Original Message----- >> From: VanL [mailto:vel2@email.byu.edu] >> Sent: Friday, October 22, 1999 6:22 PM >> To: zope(a)zope.org >> Subject: Re: [Zope] Could someone translate the debugging information? >> >> Hmm..

Hotmetal Pro 6 as Zope design tool
by Craig Allen 25 Oct '99

25 Oct '99

I've been evaluating WYSIWYG HTML editors at work and consequently downloaded an eval version of HotMetal Pro 6.0. In preliminary testing, I found it works quite compatibly with Zope. It includes bidirectional FTP, so I can navigate to a folder in Zope, edit the raw DTML documents or methods, and save it back into Zope. I haven't had the chance to do much more than a few quick edits, so can't swear that it won't mess things up, but so far looks good. Other tools seem to want to use HTML to grab content, and Zope obligingly renders the content - not what I had in mind. Anyone else taken a look at this, and any reactions?
