framed menu refresh?!?
by Mark A. Robinson 13 May '02

13 May '02

Hi all. Ok I have 2 frames in my app. Left frame is my tree'd menu with some status info, too. Right frame is my data input side. User navigates with left frame, and it anchors the appropriate page over in the right frame. Now, here's the problem: if on the right the user selects something that affects the status of the app, how can I refresh the left frame so that it will display the change in status? Thanks for any help!

making product from the filesystem
by Sylvain Thénault 13 May '02

13 May '02

hello, I'm attempting to make my first Zope product but I have some problems to install it to test it behavior. I've just put my code under the /usr/lib/zope/lib/python/Products directory, but Zope doesn't load my product. Is there anything else to do ? (there is a __init__.py which initialize the product, I took MailHost as example to construct my product) In a more general way, I don't understand how to reinstall a product which has been removed from the Zope www control panel... Does the products live in the ZODB ? Is there any problems with installing a product in Zope for testing (code may change directly in the filesystem) ? I didn't found consistent information about how to construct Zope products from the SF instead of from the www interface, and I'ld be able to read a document which answer to all those questions :-) cheers -- Sylvain Thénault

Even better, replace... <dtml-var date_posted> ..with... <dtml-var "date()-0.2916667" fmt="%A %B %d, %Y at %I:%M %p"> ..which is cleaner all around. Ron

Cannot copy/paste/rename zClasses
by Max M 13 May '02

13 May '02

Hmmm ... I have changed the meta type on a few of my zClass based products. I have also changed the "Add list name" in the factory, but I still cannot copy, move, rename etc. Has anybody got a clue?? Zope 2.5.1 but has been upgraded several times from way back. If I don't find a solution I will probably have to refactor into Python Products :-( and I could use that time for something else ... regards Max M

RE: [Zope] ZSQL questions

Hi, This was the only way I was able to get this to work. <form action="http://proton-80556:8080/intranet/input_test/manage_test" method="get"> input_test is the zsql. I tried this method <form name="form1" method="post" action="input_test"> but this is where the next thing I see is this zsql method in test mode.

How are you calling the zsql method that inserts the data? It sounds like you may be trying to pass the form variables directly to the zsql method (which isn't the best way to do it). Does your forms' "action" variable reference a ZSQL method? Jon

problem on delete off a ZObjectManager
by dorian santner 13 May '02

13 May '02

I have an object to delete (id=Santner.Dorian) and try to call a method (EPerson_delete) that is defined in the ZClass (EPerson) which simply does: <dtml-call "manage_delObjects(id)"> <dtml-if DestinationURL> <dtml-call "RESPONSE.redirect(DestinationURL+'/index_html')"> <dtml-else> <dtml-call "RESPONSE.redirect(URL1+'/index_html')"> </dtml-if> So I call http://myDomain/Test/Santner.Dorian/EPerson_delete >Error Type: BadRequest >Error Value: Santner.Dorian does not exist but it exists! Looks like Zope doesnot find the Santner.Dorian Object Funny is, that the upper method works with a simple ZClass, but does not, if the BaseClass is an ZObjectManager ! the ZClass - which does not work - extends the BaseClass ZObjectManager. So it has BaseClasses : ZObject, CatalogAwareBase, ZObjectManager (and it has several other Objects in it) while the other ZClass (where the upper method works fine ) only has: ZObject, CatalogAwareBase how to delete an ZObjectManager ?

Passing parameters into SQL methods
by Dennis Allison 13 May '02

13 May '02

I have a DTML method C which is called from another DTML method B, itself called from a DTML method A. I set a variable, call it X, in the namespace of A with a <dtml-let, and another variable, call it Y, is set with a <dtml-let in B. Both are visible in C (Thanks for the help there, Dieter...) The body of C is a <dtml-in that references the SQL method and then, in the form's body, renders the returned rows in an apropriate fashion. The query itself is paramterized by X and Y, the parameters appearing in the query in <dtml-sqltest tags. The query works from the test framework. >From the diagonstic reports I get when I publish the page, the parameter values set in methods B and A do not appear to be available in the SQL query even though they are available in C's namespace. (In formulating the query method, the name X and Y appear as parameters.) -dra

URGENT -Version Blow-Up
by Dan Shafer 13 May '02

13 May '02

I have managed to get myself into a gnarly position from which I cannot find an escape route. The site I'm building is currently absolutely unusable as a result. I was making extensive changes to a page, so I created a version (called "adding scripts" -- notice the space, which I think may be a culprit here). I started using the version, made the changes to the page in question, saved changes, tested the page and, after a few more tweaks, got it where I wanted it. So I went to the version page figuring I'd commit the changes. It said there were no unsaved changes. I stopped using the version and when I went back to the ZMI, the changed page had a version lock on it and there was no unlocked/original version of the page showing up. That's when I noticed that even though I had quit using the version in question, the page still showed that I was using it.That's also when I noticed that the top of the page that showed what version I was using called the version simply "adding" rather than "adding scripts." After several more start using - stop using sequences, I could not get out of this morass. I restarted the Zope server. No effect. I quit using the version and deleted the version object. I know, bad move, but I did not receive a warning from Zope about this. It just happily deleted the version, an action which I later found out was undoable. So now Zope thinks I am working in a non-existent version and it won't let me use the site past a certain point (even though the process I'm testing with doesn't even use the changed page). I get a version lock error. This is clearly a Catch-22. Is there any way out of this? This is the first thing I've run into in the ZMI that seems to me just not to work very well or to be documented clearly or something. I've used versions in the past successfully, and this just has me bewildered. And my client very angry. HELP!!!!!!!!!!!

ZEO Client with a custom INSTANCE_HOME
by Igor Stroh 13 May '02

13 May '02

Hi there, I'm trying to setup a "discless" ZEO client. The INSTANCE_HOME is pointing to '/var/run/zope'[1] (/var is mounted on a ramdisk). If I try to start zope with `/usr/sbin/zopectl -I /var/run/zope/ start -P 8000 -u www-data -D` I get the errors in [2]. The custom_zodb.py looks like [3]. Afaik all file permissions/modes are set correctly, what else might be the reason? ZEO is running smooth, everything works if I try to run Zope with a default INSTANCE_HOME. If I remove the old INSTANCE_HOME and supply a custom one I get those erros in [1]... some more info: Zope version: 2.5.1-1 (from debian woody) python version: 2.1.3 Thnx in advance, Igor [1]: NFSROOT@test1:~# ls -l /var/run/zope/ /var/run/zope/var total 12 -rw-r--r-- 1 www-data www-data 39 May 13 17:54 access -rw-r--r-- 1 www-data www-data 90 May 13 17:54 custom_zodb.py -rw-r--r-- 1 root root 245 May 13 18:38 custom_zodb.pyc drwxr-xr-x 2 www-data www-data 0 May 13 19:02 var /var/run/zope/var: total 0 -rw-r--r-- 1 www-data www-data 0 May 13 18:33 Z2.log [2]: NFSROOT@test1:~# /etc/init.d/zope start Starting Zope...------ 2002-05-13T17:19:19 INFO(0) client Trying to connect to server: ('<some IP>', 7700) ------ 2002-05-13T17:19:19 INFO(0) ClientStorage Connected to storage ------ 2002-05-13T17:19:19 INFO(0) ZODB Opening database for mounting: '142508672_1021297398.478297' ------ 2002-05-13T17:19:19 INFO(0) ZODB Mounted database '142508672_1021297398.478297' at /temp_folder ------ 2002-05-13T17:19:19 INFO(0) Zope Default Object Creation /usr/lib/zope/lib/python/../../import/Examples.zexp examples import file could not be found. ------ 2002-05-13T17:19:19 INFO(0) ZServer HTTP server started at Mon May 13 19:19:19 2002 Hostname: test1.domain.tld Port: 8080 ------ 2002-05-13T17:19:19 INFO(0) ZServer FTP server started at Mon May 13 19:19:19 2002 Hostname: test1 Port: 8021 ------ 2002-05-13T17:19:19 ERROR(200) ZServer Cannot write PID file. ------ 2002-05-13T17:19:19 PANIC(300) z2 Startup exception Traceback (innermost last): File /usr/sbin/zope-z2, line 627, in ?
