Handling Session Timeouts
by Michael Fox 05 Jun '02

05 Jun '02

Hi *, In an attempt to handle session timeouts, I'm wondering if someone on this list can enlighten me. My application utilises Zope's Transient Object Container & Session Data Manager. Once a user is authenticated, I set several variables in my Session Data Manager with the values from a HTML form - <dtml-call "REQUEST.SESSION.set('var1', var1 )"> <dtml-call "REQUEST.SESSION.set('var2', var2 )"> <dtml-call "REQUEST.SESSION.set('var3', var3 )"> Now these are variables are in my SDM, I set these in my standard_html_header as such... <dtml-call "REQUEST.set('var1',REQUEST.SESSION['var1'])"> <dtml-call "REQUEST.set('var2',REQUEST.SESSION['var2'])"> <dtml-call "REQUEST.set('var3',REQUEST.SESSION['var3'])"> This way I can access any session variables via <dtml-var var1> rather than <dtml-var "REQUEST.SESSION['var1']"> Am I on the right track so far? My problem is handling timeouts. My Trasient Object Container has a timeout value of 20 mins. In my attempt to handle timeouts, I have the following code in my standard_html_header - <dtml-if "REQUEST.SESSION.has_key('var1')"> the session still has this key, therefore must be active, do nothing. <dtml-else> <dtml-call "RESPONSE.redirect('login_page')"> </dtml-if> * The rest of my HTML code goes here. The problem is the redirect isn't working and Zope attempts to render the page... thus resulting in a Zope error. Does anyone have a working solution to this? or could point me in the direction of some Docs/HOW-TO's? Any help appreciated. Regards, Michael

Looking for Mailinglist-Webboard-Product
by Jan Ulrich Hasecke 05 Jun '02

05 Jun '02

Hi, I do not really like webboards like squishdot, I prefer mailinglists. Mailman is great and comes with an archive. Is there any product which would publish the mailman-archive in a webboard-manner, so that people could easily follow the discussions via their browsers and could, if allowed, post into the list using the webboard-interface or their favorite mailer. (Mh, perhaps broken mailers would cause ill threading...) I know their is ZMailman but it looks like a interface to manage mailman or integrate the webinterface into a zope-site. Ciao! juh -- Muss ich, oder läuft die EXPO auch ohne mich? http://www.sudelbuch.de/2000/20000531.html

Zope Page Template : Access denied error
by Yaser Ansari 05 Jun '02

05 Jun '02

Hello Experts, I am new to Zope. I have Zope2.5.1 installed on my win2000 machine. I have made a Page Template object which has the following code(example from ZopeBook). <html> <body> The URL is <b tal:content="request/URL" >URL</b> <table width="100%" border="1"> <tr> <th>S.No</th> <th>ID</th> <th>MetaType</th> <th>Title</th> </tr> <tr tal:repeat="item container/objectValues"> <td tal:content="repeat/item/number">#</td> <td tal:content="item/getId">Id</td> <td tal:content="item/meta_type">Meta-Type</td> <td tal:content="item/title">title</td> </tr> </table> </body> </html> When I try to test this PageTemplate with ZopeManagement Interface--->Test Tab, I am prompted to Login with userid and password. I don't understand why this happens since I am already logged in as role Manager and own this PageTemplate Object. Even after giving the userid and password I get an access denied error message. I am not able to understand why this happens. Please help me.. Warm Regards, Yaser

CatalogAware PropertyManager
by Garikoitz Araolaza 05 Jun '02

05 Jun '02

Hi! I wrote a custom CatalogAware object class inheriting from PropertyManager. I'm managing the properties with the regular PropertyManager form (manage_propertiesForm) but I'd like the propertymanager to call reindex_object() each time I modify something. I suppose that the quick'n dirty solution is adding reindex_object() at the end of the manage_editProperties method. But I don't know if there is a cleaner solution or if it will badly affect the rest of objects using PropertyManager... Any hint? Thanks Gari

RE: [Zope] XML in Zope
by sean.upton＠uniontrib.com 05 Jun '02

I would think ParsedXML+DOM in Python Scripts+DTML/ZPT would work here??? Contrary to popular belief, I don't think ParsedXML is "dead" - it works quite fine, thank you, for all the DOM L2 stuff I do, which is likely why there hasn't been a lot of development... and I've seen that Martijn Faassen has been doing some small improvements in CVS in the last few days. All this assumes small documents like forms and news-articles, not book-sized docs, since nodes in a ParsedXML doc are not manageable, so each edit reqires the whole DOM from the document object downward... I've used this type of setup for interactive form applications as well as XML-stored content applications and been quite happy, but I've been doing a lot of DOM-in-python-scripts coding; it is a bit tedious to code for, there is a lot of recursion to think about, etc.... but once you get it right, it just works... Alternately, I think you could put any Python XSLT on top of this with a few external methods, though I think it's a bit hackish since you would be printing XML, outputting it to a string, and having it parsed again (but, hey, if it works...) - as long as you are not indexing the results of XSLT in a Catalog index for a bunch of docs! As an aside, it sounds like you need to make a lot of revisions to your documents, and if you store them in the ODB it might create bloat in a versioned ODB unless you pack frequently. A brief thought for you: create something that will do application-level versioning and use non-undo mounted storage for a repository for your documents... Consider creating a folderish type whose instances contain a few specialized objects: one is a ParsedXML DOM object that contains the current XML for your document; your folderish base object could optionally be coded to act as a proxy to this contained DOM. Also, create a simple type that contains previous revisions of the XML as string-based properties, rather than storing a full DOM for each revision. Alternately, use compression methods to compress these archived revisions XML and use file objects containing the compressed text. Then, keep track of things with a state table of some kind. The downside to this is that you would have overhead in converting XML to DOM every time you loaded up a previous revision, but from a storage perspective, this should work quite well. A caveat: I haven't done exactly this before, but, after serious thought, this is the approach I plan to take with a project I am starting work on for XML-based content types in our content management system, and my hunch is that this will work quite well. Cheers, Sean -----Original Message----- From: Dan Shafer [mailto:pydan@danshafer.com] Sent: Wednesday, May 15, 2002 9:45 AM To: Chris Withers Cc: Dan Shafer; zope(a)zope.org Subject: Re: [Zope] XML in Zope OK, I'll be happy to describe the problem. I'll try to be brief but clear. In the briefest terms I can come up with: I need a way of storing a document-like object in the ZODB which will be sufficiently structured to allow the selective display and replacement of its elements while allowing for the immediate display of its contents as a nicely formatted document in a browser. Now for the longer-winded version for those with the patience or curiosity to read more. I am building an application which is quite document-centric. When the client interacts with the application, he is building a "record" of an interaction with a patient. This interaction can extend over a period of days, so it needs to be able to be resumed. The application now consists entirely of HTML forms which trigger Python scripts that initially create and then update a DTML Method object. I embed formatting into the DTML Method so that when the user wants to see a report of the patient interaction, all I have to do is give him a way to view the document. The client *loves* the application as it has developed so far, in part because as the code updates the DTML Method during the patient interaction, a supervising clinician can see the progress of the interaction as it develops. So I prefer not to lose the ability to allow the supervisor to see the document the code is generating, but I may have to do so. When the interaction with the patient proceeds linearly and in one session - which is most often the case - this system works like a charm. But if for any reason the interaction gets interrupted, my scripts, which always merely *append* information to the end of the document as each step proceeds, are not now capable of a smooth resumption in place. This would require, e.g., that information now stored in the DTML Method be parsed out to supply initial values to fields on the interactive form that have already been completed. That is the minimum I need, but as I have been thinking about the design, I've decided I actually need much more than that. I believe the best way to accomplish that objective of maximum flexibility for the user is to use a more structured approach to the document. As I see it, I had three alternatives: (1) parse the text in the DTML Method to pull out and rewrite pieces as needed; (2) use properties of the DTML Method in addition to text content and link the two; (3) go to XML to take advantage of readily available Python techniques for managing the structured data while being able to use XSLT to retain the ability to show the document in process immediately on demand. I spent some time looking at the first option and decided it was going to be terribly inefficient. I would in essence have to define my own start/end tags for each element of the document (which I could use comments for) and then manually parse them. Ugly. The second approach also felt inefficient because I would be storing all of the information in a document twice, once as a document (so that it could be displayed quickly on demand) and once as properties (so they could be retrieved and replaced as needed). I have not completely discarded that approach but XML seems more promising. I am fully aware of the horrendous overhead associated with XML documents but these documents are quite small (3-4 pages on average, printed) and always identically structured. With Python's excellent XML support, I have already gotten some very good routines written to parse such documents. My problem is that when I try to translate that code to Zope External Methods, they don't work and debugging them in Zope is a nightmare. I am learning, and I am open to any suggestions or corrections to my thinking. I appreciate the group's patience with me and any ideas you have.

Make Navigation
by Jaroslav Lukesh 05 Jun '02

05 Jun '02

Hi, I want to make navigation DTML methods for: But I have these problems: * child level - it works even in folder that does not have own index_html method inside: ------------ <dtml-in "PARENTS[0].objectValues(['Folder'])" sort=title> <a href="<dtml-var URL1>/<dtml-var id>"><dtml-var title_or_id></a><br> </dtml-in> And what for thats ? * parent level (list of all objects at above level of hierarchy) * top level of web --------------- <dtml-in "PARENTS[-1].objectValues(['Folder'])" sort=title> <a href="<dtml-var URL1>/<dtml-var id>"><dtml-var title_or_id></a><br> </dtml-in> --- but this is problem, because this make list of "Root Folder" objects. I want to have list of topmost objects in first level of subdirs (alias future virtual webs). Many thanks for help.
