Do you know why you use DTML Method, or you use it because you have just few lines of code here? Try to play with acquisition: <dtml with aq_explicit> ---------acq---------- <dtml-var bilgi_cs_index> </dtml-with> --------/acq----------- <dtml-var bilgi_cs_index> But it raise error if you does not have called object here. Please make more comments on what you wan to have and code of bilgi_cs_index and my_index. Regards JL.

Parsing of Page Templates and replicating ZMI Tree Structure
by Anitha George 18 Aug '03

18 Aug '03

Hi All I am working on Zope-2.5.1 running on Linux . I need to create a site Map of my site which needs to be built dynamically. The Site Map needs to consist of all Folders and Sub Folders and Files within these folders as well as anchor Tags within each of these files. Something like the ZMI Tree on the left but more detailed. My SiteMap needs to cover all Folders,SubFolders and Files and also anchor Tags within each files(<a name....) By going through the examples of Example Folder in Zope I have been able to get an example working for getting all Files and SubFolders within a Folder. But How do I get all files and SubFolders under every Folder in my Sitemap as soon as it loads? Also how do I get all anchor tags within a page to load? I guess it would be like a DO-WHILE loop which will go from one folder to the next and create a view of all subfolders,files and anchor tags(for which I may need to parse through the PageTemplates searching for <a name tags... --or is there some other way? ) within each file for every folder in the Root of the Zope . Could you guys please help me out here? All help is greatly appreciated. I hope I have been clear in stating my problem. Kindly help me out here. Thanks for all Anitha _________________________________________________________________ Add photos to your e-mail with MSN 8. Get 2 months FREE*. http://join.msn.com/?page=features/featuredemail

Easy :-) You need to call folder "Otherthing", not a page "Otherthing" 8-) http://xxx/Something/Otherthing/ ^ Regards JL.

Please inspire yourself with this DTML Method called "x_ST"" that deletes all images in folders "s" or "t" recursively if they present: <dtml-in "objectValues([ 'Image', 'Folder', 'ZipFolder' ])" skip_unauthorized> <dtml-if "_['sequence-item'] in ('s', 't', 'xs', 'xt')"> <dtml-let container=this> <dtml-in "objectValues(['Image'])"> DEL: <dtml-var absolute_url> <dtml-call "container.manage_delObjects([getId()])"> </dtml-in> </dtml-let> </dtml-if> <dtml-if "(meta_type=='Folder') or (meta_type=='ZipFolder')" ><dtml-with sequence-item ><dtml-var x_ST ></dtml-with ><dtml-else ></dtml-if ></dtml-in> Regards JL.

Re: [Zope] LocalFS - large files / broken connections

Hi, FreeBSD has some problems with python if you use it much. It is best to search archives for BSD unpredictable problems with Zope, it wants some more memory for something (stack??) than default 64kB. Maybe here could be your problems. Regards JL. ---------- Odesílatel: David Siedband <david(a)calteg.org> It's on a Sun e3000 running FreeBSD.

Hi David, do you use windows, true? Use linux, not windows! I have no problems under Linux, but few unresolved problems under windows (same version of zope, same products, same dats.fs) in windows.

Redirecting based upone user
by Simon Faulkner 17 Aug '03

17 Aug '03

I have a list of users names in a MySQL table and I would like to write an index_html ZPT that sends the user to show_depots?depot=user/GetUsernName (ZPT) if they are in the MySQL list and show_countries (a different ZPT) if they are not. How should I go about this? Do I make index_html a Python script or ask them to login to a script /tracking/login maybe? Simon

Creating products
by Dustin Mitchell 17 Aug '03

17 Aug '03

I can't seem to find the straight dope on this one in the documentation. I have a Python product, named Volunteer. It has several classes defined within it (VolunteerUserFolder, Opportunity, etc.). Each class defines constructors e.g., manage_addOpportunity and manage_addOpportunityForm. In order to instantiate one of these classes programmatically, I know I need to do something like: context.manage_addProduct['Volunteer'].manage_addOpportunity(title="hi") but this doesn't seem to work -- manage_addOpportunity is not found. I know that context.manage_addProduct['Volunteer'] is some sort of proxy for my product, but what is the list of attributes I can access from this point (not counting acquisition, obviously)? If I wanted to add a static product-level function (for example, run_background_check(ssn)), where would I put that function? Thanks to anyone who can shed some light on all of this or direct me toward a snippet of documentation I haven't found :-) Dustin -- Dustin Mitchell dustin@ywlcs.org/djmitche@alumni.uchicago.edu http://people.cs.uchicago.edu/~dustin/ PGP Key: http://people.cs.uchicago.edu/~dustin/pubkey.txt
