Hi All, I've recently fallen in love with zope, using it for 2 large charity projects I am doing in my free time. Does anyone know of any zope hosting companies based in the UK and/or do you think there would be demand for such a monster? Regards, Dan

RE: [Zope] silly IE display question - manage screens showing 'vi ew', not contents
by Meilicke, Scott 11 May '01

11 May '01

I don't - I have a laptop on win2k, and usually just 'Hibernate' - suspend to disk, instead of shutting down and restarting in the morning. I performed an update via windowsupdate.microsoft.com a few days ago and did not reboot when prompted because I was in the middle of something. I rebooted this morning, and it works fine now. For what it's worth, I'm currently running IE 5.5, sp1, version 5.50.4522.1800. Oddly enough I had the same problem last night with Netscape - once. Unfortunately I don't remember exactly what I did to correct it, but my site prompted me to log in again via a windows logon window, not the usual web logon. Sorry I didn't write down exactly what I did... Thanks for the help.

styled text editing
by Alex Burton 11 May '01

11 May '01

Hello All, not a pure Zope question here: I'm investigating solutions to input and manipulate styled text that will end up in a SQL database. It should probably be a simple interface to HTML. The goal is to allow writers to input styles into text (such as putting titles in italic, personal names in bold) without having them do HTML or structured text, nor cut&paste into a visual HTML editor. This SQL data will head one way back onto the web (live zope) and the other way into a print layout program (probably as an XML file). What i would need is , , , , <hn>, maybe <dir> based on tabs, you know, just the basic stuff. Possibilities i can think of: A Java applet that talks to Zope or SQL (like the new(?) hotmail editor). A Flash file that talks to Zope (assuming there is a Flash widget to do such editing) An SQL-aware app on the desktop (made in VBasic or something like that) ...? It actually does not have to be HTML, as long as Zope can deal with it (can go in a SQL blob). Anyone worked or stumbled upon something like this? We may have some resources to do development towards this, so general pointers and ideas are also welcomed. Thanks, Alex.

user roles in standard_error_message
by Danny William Adair 11 May '01

11 May '01

sorry sorry sorry, I just reinstalled my email client and didn't turn off html sending... sorry Hi! While customizing my standard_error_message, I ran into a little problem: Someone with the role "Member" is logged in and tries to access a resource that does not exist. Same could happen to someone who doesn't have that role (Anonymous). Now I have two different style sheets for members and non-members: A member might click on a broken link from within the members-only area (having a... pink background), the anonymous user clicked the same broken link from a publicly accessible area of the site (having a... silver background). I would like to keep the different background colors when showing my error message so I put a <dtml-if "AUTHENTICATED_USER.has_role('Member')"> <dtml-var "members_css"> <dtml-else> <dtml-var "public_css"> </dtml-if> in the head section of standard_error_message (these *_css are ZStyleSheets) My problem is, that it's always the public_css that will show up. So I checked with <dtml-var "AUTHENTICATED_USER.getRoles()"> in both the members area and standard_error_message. To my surprise the member role was gone: In the members area getRoles() returned ('Member',) while in standard_error_message ( _.str(error_type)=='NotFound' ) it returned ('Anonymous',) btw, the role is not really "lost", I can go back to the members area and click through members-only pages without problems. What's happening? This looks like buggy, naughty misbehavior :-), doesn't it? tia, Danny

forcing a ZEO client to retrieve something from it's server.
by Anthony Baxter 11 May '01

11 May '01

For testing the state of a system, I want to be able to do a request that confirms that a ZEO client is alive, and that it's backend server is alive. I know I can do something like a write, but I really, really don't want to do that - Data.fs bloat. Is there a way to make a ZEO client get something from the server? Can you make an object that the ZEO client won't cache? ta, Anthony

Product event when zope restarts
by Jan 11 May '01

11 May '01

Hello all! I have been developing a Zope Product that basically reads in a file and shows it in zope. The problem is that when the file is updated in file system, that is not updated in zope. I do not want it to read the file every time it is accessed in zope. Refreshing it every time the zope restarts seems to be the solution. So I was wondering if there is a function that will be executed when zope restarts. Thanx.

ZServer Must Be Continually Re-Started
by Ben Ocean 11 May '01

11 May '01

Hi; I'm still having problems with ZServer quitting on me on a whim. Can someone help me figure out how to trouble-shoot this? I just installed the latest distro, so it's not the *old bug* that plagued earlier versions. TIA, BenO

Using an arbitrary connection on a ZSQL Method
by Andy McKay 10 May '01

10 May '01

Just did a useful hack I wanted share... Occasionally I find it useful to have one SQL Method that I can call with a different DB connection, programatically. For example I have a test and a live database. Using manage_editProperties each time of course means writing a new copy of the object. The following patch means that you can override the connection_id on the ZSQLMethod with CONNECTION_ID in REQUEST. This could be cleaned up a little of course but I found it useful in conjunction with session management. --- l:\lib\python\Shared\DC\ZRDB\DA.py Thu May 10 16:29:25 2001 +++ q:\lib\python\Shared\DC\ZRDB\DA.py Thu May 10 15:08:36 2001 @@ -457,11 +457,14 @@ if hasattr(self, 'REQUEST'): REQUEST=self.REQUEST else: REQUEST={} - try: dbc=getattr(self, self.connection_id) + if REQUEST is not None and REQUEST.has_key('CONNECTION_ID'): c_id = REQ UEST['CONNECTION_ID'] + else: c_id = self.connection_id + + try: dbc=getattr(self, c_id) except AttributeError: raise AttributeError, ( "The database connection %s cannot be found." % ( - self.connection_id)) + c_id)) try: DB__=dbc() except: raise 'Database Error', ( Cheers. -- Andy McKay.

<dtml-in> looping over lines in document
by Laurie Nason 10 May '01

10 May '01

Hi guys & gals, Is it possible to use <dtml-in> over a DTML method's text and get each line out one by one. I know there is a lines property but am not sure how or if it can be used in this context. The reason I am asking is that I am trying somehow to store my lookup values for my select boxes in one folder with each lookup having a separate DTML method containing the values. If anyone has a better idea, please let me know. Thanks, Laurie Laurie Nason Dept. of Biochemistry - N420 Baylor College of Medicine Houston. TX77030
