There are a couple of items in play here: * Nested ZClasses are *always* addable in their containing ZClass, so they don't show up as options in the Subobjects tab. * If you have *exactly one* nested ZClass in a container ZClass, *and* you have not specified any "outside" objects as addable on the Subobjects tab, then the only objects which will be addable in the container ZClass are instances of the nested one; in this case, the management interface does not display a dropdown list, but only the "Add" button (try clicking Add on your Whiteboard object's Contents tab). The bad news here is that there are some weirder interactions possible, as well (several recent Collector issues come to mind); the good news is that they are almost all related to the UI -- the underlying object system is pretty sane.

User DB, GUF, et al broken under 2.1.7?
by jiva＠devware.com 18 Jun '00

18 Jun '00

Is it just me or are about all the third party ACL folders broken in 2.1.7? I have tired User DB, and GUF and can't seem to get either to work. I was one of the bright fellows who updated to 2.1.7 immediately when it became available from 2.1.4, and now all my user folders are broken and I (like an idiot) did not make a backup before upgrading. (Well I did, but I actually have done some work on the site since then, and it seems the Data.fs is not compatable if I take it from 2.1.7 and try to use it in 2.1.4. ARGH... Help! -- Did I say I was a sardine? Or a bus???

I would guess that you are using the Washington University IMAP daemon, which has unfortunately chosen to treat your entire home directory as a possible mailbox -- what is probably happening is that you are not really hung, but are stuck running stat() on every file under your home directory. To test this, add a new, bogus user to your system, and clean out any "skeleton" cruft from ~/bogus. Try logging in to WorldPilot -- if that works, then you need to search the archives from February for notes on WU IMAP. > > Trimming the contents of my mailbox down to just 6 messages didn't > seem to make any difference. > > Anyone shed any light? > > Oh yes, I have applied the imap.py.diff patch to the python library. -- =========================================================== Tres Seaver tseaver(a)digicool.com Digital Creations "Zope Dealers" http://www.zope.org

I'd keep the drop-down menus in javascript. You can do similar things in zope (i.e. the tree tag or the tab bar at the top of the management interface), but then every change is a fetch back to the web server. If you keep the javascript then it all happens at the client. If you want you can generate the javascript with dhtml. That way the contents of the menus can follow your site. You'd have to set the comtent type so that the browser thinks it is javascript. (hmm, how is javascript cached??) -- cary [snip]

nested dtml-in with sql method -namespace problem (?)

hi all, i have posted this question a while back, but got no replies. maybe imy question is a bit off or unclear. so here it is again. rephrased. i have 2 sql methods. sql1, and sql2. sql 2 got the parameter for it's query from sql1. as follows: -- <dtml-in "sql1"> <dtml-in "sql2(obj=myobj)"> do stuff </dtml-in> </dtml-in> -- sql1 is just a query that returns myobj that will be used by sql2. this used to work on 2.1.6 but not anymore on 2.2 i guess tmyobj is not in the namespace. even tried passing _.None, _,obj=myobj but resulted the same error. the traceback raceback (innermost last): File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/kdie/Zope-2.2.0b1-src/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /home/kdie/Zope-2.2.0b1-src/lib/python/OFS/DTMLMethod.py, line 168, in __call__ (Object: index_html) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_String.py, line 500, in __call__ (Object: index_html) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_In.py, line 611, in renderwb (Object: qry_msgs_by_par_id(par_id=0)) File /home/kdie/Zope-2.2.0b1-src/lib/python/OFS/DTMLMethod.py, line 164, in __call__ (Object: show_subtree_index) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_String.py, line 500, in __call__ (Object: show_subtree_index) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_In.py, line 633, in renderwob (Object: qry_msg_thread(par_id=obj_id)) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_Util.py, line 339, in eval (Object: qry_msg_thread(par_id=obj_id)) (Info: qry_msg_thread) File <string>, line 0, in ?

SMTP server external method??
by Jon Brisbin 18 Jun '00

18 Jun '00

Has anyone attempted a python-based SMTP server that creates a Zope object immediately upon recieveing email??? If not, how do you handle email in zope for a web-based system?? just periodically create objects from the contents of /var/spool/mail/user ... or use some other method?? ideally, the object's various properties would be set upon instantiation...stuff like header fields would correspond to properties...etc... For those that handle email in Zope, how do you approach this?? thanks!! Jon Brisbin jbrisbin.net

Josh, This is a "zope(a)zope.org" question, not a "zope-dev(a)zope.org" question, so I've moved the thread to there. You can do what you want in a couple of ways: 1: Cookies Can your HTTP clients use Cookies? You can send a cookie on one page and retrieve it on the next. Look at the "Zope Developer's Guide" and for information on Cookies and the RESPONSE variable. Watch out though -- if you pass data in a cookie, and expect to use that data retrieved later, you could be opening yourself up to a security risk. A client could change the data in the cookie to mean something different, and you might never find out. 2: Sessions Use one of the NNNSession products, such as FSSession or SQLSession. These use cookies behind the scenes, but present you with a nice programming interface. Also, your actual data (session variable and so forth) live on the server. The cookie just tells the server where to find them. Thus, no part of your data is entrusted to the client. I'd suggest you look at the FSSession product: http://www.zope.org/Members/gaaros/FSSession Or perhaps HappySession: http://www.zope.org/Members/hungjunglu/Products/HappySession -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net
