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

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 <em>%s</em> 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

History of DC and/or Zope
by Andy McKay 10 May '01

10 May '01

I'm looking for any documents about the history and beginning of Zope. (Searches on Zope.org have turned up nothing so far, still searching) I'm giving an intro to Zope talk to developers and wanted to quickly cover the history of Zope / DC etc. If there any suitable talks on this topic, pointers to those would be appreciated too :) Thanks. -- Andy McKay

It's still at firstworks. His hosting co was acquired and he had to make a DNS change. You should be able to hit it sometime soon (next coupla days). I got it just fine.

I would use "load_site.py" (in the "utilities" subfolder of the Zope distribution) as a base and extend it with the property addition. Dieter

This could happen, if "manage_addExtFile" would be a DTML object. You should check the "signature" of "manage_addExtFile", i.e. what parameters it wants. Furthermore, we might help you better, if you include the traceback in your problem report. Dieter

Re: [Zope] view management screens

The call of our external methods (that we use intensively) are protected by view permissions. Only "manage_main" (to edit the methods) are protected by "View management screens". Dieter
