[ZClass]User Form to add an Instance of one ZClass to an instance of another ZClass of another ZClass
by Farrell, Troy 16 Jan '01

16 Jan '01

Hello all- Being new to ZClasses, I'm having some difficulties. I have a ZClass NetShowLogFile. I can add this to normal Folder Objects through the management interface. I have a second ZClass StreamingEvent. I would like an user to be able to add a NetShowLogFile to an existing Folder Object logs inside StreamingEvent. StreamingEvent L__logs (folder object) L__newNetShowLogFile (DTML method) L__newNetShowLogFileForm (DTML method) If I have a BigEvent StreamingEvent and a user goes to: http://localhost/BigEvent/newNetShowLogFileForm They get a form where they upload a log file through a <form action="newNetShowLogFile" method="post" enctype="multipart/form-data"> If newNetShowLogFile only says: <dtml-var REQUEST> none of the form variables are passed by NS6. 1)Netscape 6 (WINNT 4) is not passing REQUEST properly when the form enctype is multipart/form-data. Anybody else seen this? IE5.5 seems to get it okay. Next: newNetShowLogFile looks like this: <dtml-if "REQUEST.has_key('id')"> <dtml-with logs> <dtml-with "manage_addProduct['NetShowLogFile']"> <dtml-var "NetShowLogFile_add(_.None, _, REQUEST)"> </dtml-with> </dtml-with> <dtml-else> Netscape lost the REQUEST again. </dtml-if> This calls NetShowLogFile_add in the same way the management UI does. However, IE is not able to do the <dtml-call "propertysheets.NetShowLogFileProperties.manage_editProperties(REQUEST)">. I keep getting the error that I am unauthorized to access manage_editProperties. I don't know which permissions I need to adjust on the ZClass. Thanks for reading my long email. In case you are curious, I am writing a Zope/Python-based streaming media log file analyzer.

by seb bacon 16 Jan '01

16 Jan '01

I'm writing a minimal product for which I'm getting a Error Type: AttributeError Error Value: commit_sub from the transaction machinery. The traceback's no help. The offending code, however is: class Foo(SimpleItem) def __init__(self, id, title, file): self.file = Image('file',title,'') self.file.manage_upload(file) Can anyone tell me what's wrong here? Cheers, seb

RE: [Zope] Adding content type to internet explorer
by Farrell, Troy 16 Jan '01

In W95/NT: Open a File Explorer window (not IE) and select Options from the View menu. The popup will have a tab labeled File Types. This is how you change windows MIME types. In W98/2k: I don't remember and I don't have it with me. It is a similar option under IE (since there is no normal explorer. The settings are stored in the registry, but this is the easiest way to edit them. Please try to keep the list topics to zope. Thanks.

Jeff, We use an EventFolder on our intranet. Basically, how do I get a <dtml-in> of data in todays entries in the EventFolder? I want to publish in another list somewhere else with a title like this: "Today's Happing For Those Who Don't Care To Go To The Intranet And Click Our EvenFolder" Best regards, Peter

Re: Zope and OpenBSD 2.8 news?

I just asked the question on the OBSD misc list. If OBSD's threads lib is the problem then we need to create some traffic *there* to be heard and not here on the Zope list. So please join the thread on misc and we might get a fix sooner.

Re: [Zope] My Add list is so full...

<simple solution untested> Add a (lines) property (called: i_filter_meta_types) in the root of the meta_type name of the objects you don't want to use. I.e DTML Document XMLDocument .... Next, you modify the file main.dtml in lib/python/OFS At around line 95-100 you'll see this: <dtml-in filtered_meta_types mapping sort=name> <OPTION value="<dtml-var action fmt="url-quote">"><dtml-var name> </dtml-in> Change this to something like this: <dtml-in filtered_meta_types mapping sort=name> <dtml-unless "name in i_filter_meta_types"> <OPTION value="<dtml-var action fmt="url-quote">"><dtml-var name> </dtml-unless> </dtml-in> </simple solution untested> <Peter Bengtsson /> ----- Original Message ----- From: "Francois-regis Chalaoux" <Francois-regis.Chalaoux(a)sanofi-synthelabo.com> To: <zope(a)zope.org> Sent: Tuesday, January 16, 2001 8:44 AM Subject: [Zope] My Add list is so full... > Hi, > > Since long time ago I have this reflexion.

Is is possible to >organize sublist of meta-type into products sublist ? aha ... Max M's law $1: "Anything that is a list in a userinterface will eventually need to evolve into a tree." Well that doesn't help much, but at least your problem has a name now. Other than that there is nothing to do about it. Regards Max M ;-)

One relatively less tedious way to do this would be to put the session id in the URL rather than in forms; you can do this by using an access rule along the lines of: <dtml-let stack="REQUEST['TraversalRequestNameStack']"> <dtml-if "(stack and stack[0][:6]!='manage')"> (assuming the next component of the path is the session id, remove it from the traversal path) <dtml-call "REQUEST.set('session_id',stack.pop())"> (somehow make sure that the session_id is valid and revive the session object. With SQLSession, may be done by <dtml-call "Session(session_id)"> (path in the next line is supposed to be replaced by something which, preferebly dynamically, retrieves the path traversed up to this point. This is needed so the session id shows up in URLs generated down the tree) <dtml-call "REQUEST.setVirtualRoot(path+'/'+session_id) </dtml-if> </dtml-let> What this does is translate a url of the form http://server.com/123456/real/path to http://server.com/real/path for resource-search purposes, while making sure that all calls to absolute_url() return urls of the form http://server.com/123456/... . This means that as long as you rely on absolute_url rather than relative links, you're essentially done. This ignores session initialization first time, but I hope the general idea of how to do this is enough. I don't have a live example at my fingertips, but something a lot like this was done here some time ago. Have fun, Shai.
