AW: [Zope] Understanding dtml and/or its variables
by Bartakovic, Damir 21 Feb '01

21 Feb '01

Hi, thanks. I thought I have the lastest version :( On zope.org ( http://www.zope.org/Members/zwork/Znolk_SQL_Wizard/index_html ) there is no version 0.1.3d! After searching a bit on bluedynamics I found it. Maybe someone can upload the newest version to zope.org or set a link to bluedynamics.

> So does this work with Zope 2.3 now? yes it should I've done fairly minimal testing, and it works for me, but the way it is written, it is likely that it will run with any zope release that does not change the standard user folder too much. regards, jephte.clain(a)univ-reunion.fr

Re: [Zope] NT Authentication
by jimbo 21 Feb '01

Hello, jcNTUserFolder worked for me using an earlier version of it on Zope 2.3. A new version has just been released and I'll probably will check it out in a few days against 2.3. With it I was able to authenticate and give roles to users from other domains. I would say since Python has good support for winnt services, choosing Zope with jcNTUserFolder is the way to go. ---------- Original Message ---------------------------------- From: Ricardo Bánffy <rbanffy(a)mac.com> Date: Tue, 20 Feb 2001 12:32:30 -0300 >Hi > >We were asked to install a Zope server over Windows NT.

Users/Roles in ZClasses/Products
by Bodo Bauer 21 Feb '01

21 Feb '01

Hi, I am developing a Zope product with several classes and subclasses there in. Everything works fine so far, but the next step is to add user logins and permissions to the whole structure. While I see how this is done on instances of objects, I didn't find any way to put role based permissions and role definitions into the classes defined in the product. I found a howto talking about this, but ony in respect of 'hand coded' products. So far I could do everything in dtml and would love to keep it this way. Am I lost or is there a way to do this? An example of what I like to do is to define a role 'registered_user' and restrict access to certain methods to this role. I will nedd 2 or three different roles to implement different levels of access.

Re: [Zope] Checking sequence-index using dtml-if

Thanks. Could you please help me understand the syntax of the statement you suggested? Specifically, this portion ZSQLMethod()[:3] Additionally, with this method, is there a way to process all records starting with a certain number until eof()? Thanks again for your help.

zope.org and zeo version
by Bak＠kedai 21 Feb '01

21 Feb '01

hi out of curiosity (which will surely kill the cat ;)) which version of zeo is zope.org running? 0.4.1 or the cvs? i checked out zeo out of cvs, and installed on dev machine, and all looks ok. if zope.org uses the pre 1.0 beta, i'll likely follow :) thanks -- http://www.kedai.com.my/kk http://www.kedai.com.my/eZine use Zope? then you got HOPE!

zope book - tree error
by Sandy Britain 21 Feb '01

21 Feb '01

Hi all, first I'd like to say thanks to all those who have been very helpful and answered my previous couple of questions. This is a weird one - I am trying to use the tree tag by adapting the code in the Zope book chapter 7 example. I want to display only folders containing documents in a tree on a sidebar on the site home page. my folder structure in Zope goes: Root - MyFolder - documentsFolder - docFolder1 - docFolder2 - docFolder3 - docFolder3A - docFolder3B and so on.. I have given all the 'docFolder' folder objects a boolean property 'doc_folder' that is set to true. As suggested in the book I have created a python script with the id of 'docFolders' with the following code: results=[] for object in context.objectValues(['Folder']): if object.hasProperty('doc_folder') and object.doc_folder: results.append(object) return results I then created a dtml method to display the tree called 'libraryMap'. code as follows: <p>&nbsp<a href="&dtml-URL0;?expand_all=1">Expand All</a><br> &nbsp<a href="&dtml-URL0;?collapse_all=1">Collapse All</a> </p> <dtml-tree branches="docFolders" skip_unauthorized="1"> <a href="&dtml-absolute_url;" TARGET="text"><dtml-var title_or_id></a> </dtml-tree> Both of these methods are located in the 'documentsFolder' (see Folder structure above). When I test libraryMap using the view tab in Zope it works fine (yippee!), but when I add a dtml method in MyFolder to call the method 'libraryMap' with the following code: <dtml-with documentsFolder> <dtml-var libraryMap> </dtml-with> All that gets displayed are the two hyperlinks for 'Expand All' and 'Collapse All'. So the tree doesn't seem to be working even though the method returns with no errors. Thanks in advance to anyone who can help! :-) Sandy. **NB: Interestingly, if I add a test method to the documentsFolder to call libraryMap simply with <dtml-var libraryMap> it will work if the test method is a dtml-method, but not if it is a dtml-document when the same behaviour as described above results!?

Python methods and keyword arguments
by Peter Bengtsson 21 Feb '01

21 Feb '01

Python method: Id =simple_pym parameters: val1, val2 Python method: Id =advanced_pym parameters: self, val1, val2 DTML Method: Id: index_html <code> <dtml-var "simple_pym(12,24)"> OK! <dtml-var "simple_pym(val1=12,val2=24)"> OK! </code> DTML Method Id: index_dtml <code> <dtml-var "advanced_pym(12,24)"> OK! <dtml-var "advanced_pym(val1=12, val2=24)"> FAILS!!! Error Type: TypeError Error Value: not enough arguments; expected 3, got 0 </code> Get the problem? I want to be able to call a Python Method object using keyword arguments or whatever it's called when you include the name of the parameters as you call the object. How do I do this?? Does this apply to Python Scripts and External Methods?

Apache+SSL+ZServer+LoginManager = S L O W ?
by J B Bell 20 Feb '01

20 Feb '01

After some weeks of exhausting development, I finally have a setup running with Zope that allows me to change Unix passwords with what I hope is some semblance of security. However, it's nightmarishly slow. Specs: Apache 1.3.14 w/mod_ssl (ssl 0.9.5a) Zope 2.3.0 Python 1.5.2 LoginManager 0.8.8b1 ZPatterns 0.4.3b2 Following the ZServer+Apache+SSL tutorial closely, I do eventually get a login page from LoginManager; the pictures seem to be part of what is slow. I get this tantalizing clue from my apache logfiles: "GET //p_/ZopeButton HTTP/1.0" All pages load up with nearly unbelievable slowness, often exhibiting speeds that creep down & down, though they do eventually load. Loading directly from the zope server is as quick as ever. If anyone has any clues, please let me know, I'm all ears. --JB (TQuid on #zope)

httplib (was re:throwing exceptions when <img src=...> does not exist)
by Lee Reilly CS1997 20 Feb '01

thanks, john. this looks like the best option. uploading the files to my zope server is not really an option. i've set up database simply recording, which files are held on the external server to help (as a short-term solution) but this would prove just as tedious in the long run and there's no way i'd include this is my final build. so... i checked out httplib module (HTTP protocol client) ref: http://www.gmu.edu/mlnavbar/webdev/doc-python/lib/module-httplib.html but it doesn't seem to be supported by python methods. i've managed to create a total system so far without using any external python methods (the ones stored in an extension but this seems like the only option now. can anyone tell me if there are any alternatives? thanks if you can help, lee John wrote: > - Write an external method that goes out and checks whether the image in > question actually exists on the server.
