FTP Woes and no answer
by J. Atwood 12 Jan '01

12 Jan '01

I have FTP'd into Zope before. No problems but all of a sudden it seems like neither I nor the people I am working with can FTP in with either a manager or superuser account. I have tried to change the port and all sorts of other things but on a few different installations with different clients from different machines and OSes it just does list any of the files in the directory. Has anyone experienced this? Know a work around? J

It didn't work exactly like this, but this one did exactly as shown (remeber path is like "06-01-2001/file.pdf"): <dtml-with files> <dtml-with "_[path[:10]]"> <--- this gets me into the "06-01-2001" dir <dtml-with "_[path[11:]]"> <--- this gives me the variable space for file.pdf <dtml-var size> </dtml-with> </dtml-with> </dtml-with> I'll write a HOW-TO for this in my page, I think it's worth it. Thanks for your help all of your guys ! Dimitris http://atlas.central.ntua.gr:8000

Dimitris Andrakakis writes: > <dtml-var "_.get_size(_['<dtml-var "path[11:]">'])"> This is an FAQ (as you can imagine). The list has a searchable archive, where you can find anwsers to FAQ's. I think, you will also find a compiled FAQ list via the Zope documentation portal (zdp.zope.org) This time, still , I will answer your question: if you would like to use "<dtml-var ...>" inside a Python expression, you can simply omit it (just use the "...") in most cases. It is more safe, however, to use "_[...]" instead, as this gives the same result. In your case (I suppose "path" is a string giving the filename (without path component) that can access the file from the current context!), you could probably use: <dtml-var "_.get_size(_[path[11:]])"> If "path[11:]" contains pathname component, you probably will need to use "restrictedTraverse" (--> Online API reference).

Re: [Zope] ZCatalog uniqueValuesFor
by Dieter Maurer 12 Jan '01

aZaZel writes: > ... "uniqueValuesFor" not updated after modification ... Almost surely a small bug in ZCatalog. A field index is implemented as a mapping from values to lists of documents. "uniqueValuesFor" returns this mapping's "keys()". When the field value of a document changes, this document is removed from the corresponding list. Obviously, a test is missing whether the result is the empty list. If it is, the key should be deleted. Probably, you can fix this yourself. The code is in "SearchIndex.UnIndex". If you fixed it, file a bug with patch report into the Collector. Dieter

Re: [Zope] Problem on using nested <dtml-if>&<dtml-in>

angie tel writes: > ... > <dtml-if ...> > <dtml-in sql1> > </dtml-if> As you recognized DTML tags must be *properly* nested... You can do: <dtml-if ...> <dtml-call "REQUEST.set(sql,sql1)"> </dtml-if> .... <dtml-in sql> .... </dtml-in> This way, you get a properly nested DTML structure. Dieter

You could use <dtml-call "REQUEST.set('userid', _.getitem('979226100'))"> Dieter

whitespace normalization (was: [Zope] way to cleanup form input text?)
by Dieter Maurer 12 Jan '01

12 Jan '01

Chris Beaumont writes: > ... whitespace normalization ... An idiom for whitespace normalization is: "_.string.join(_.string.split(text_to_be_normalized))" It will replace any sequences of consecutive whitespace characters by a single space. You can not use it in all cases, as sometimes newlines are semantically important. The above idiom would convert them into space. Dieter

Zope 2.3.0 a2 and ZClasses
by John Verzani 12 Jan '01

12 Jan '01

I am trying to upgrade my zope to see the new features in 2.3.0 a2 (from 2.2.4). I installed, copied my previous /var /Extensions start stop and access files and then started up zope. All works well *except* the few zClasses that I had written now do not work. They have survived previous upgrades. Can anyone point me in the right direction? I am unclear how to debug this as there are no apparent error messages. Thanks, John -- .................................................................... .

upgrading from 2.1.x to 2.2.5+ (on Winxx)
by Bill Seitz 12 Jan '01

12 Jan '01

Was there ever a binary to upgrade from 2.1.x to 2.2.0 or the equivalent? Could it be rescued? Now there appears to be no upgrader, and the manual upgrading process described in http://www.zope.org/Members/mcdonc/HowTos/zopeinstall/ZOPE-INSTALL-HOWTO doesn't sound fun (esp. as it's written for Unix). I have to do this on a few different machines (Win98 laptop, Win2K desktops/servers), so time/error savings would be nice... __________________________________________________ Do You Yahoo!? Yahoo!

ZMySQLDA and aggregate functions on Win

This is curious to me - I tried this on my Linux platform from mysql and it doesn't work. Perhaps I misunderstand what you are trying to do: SELECT COUNT(*) FROM mytable - returns a number - so I really don't expect it to work. I have a table - shop and a column in that table - article: mysql> select count(*) from show group by article; ERROR 1064: You have an error in your SQL syntax near 'show group by article' at line 1 Sorry if I misunderstand what you are trying to do - ================================= Dave Woolston davew(a)digicool.com Digital Creations www.digicool.com (716) 262-4715 > I have a problem with ZMySQLDA and aggregate functions in combination with > grouping on Windows. > When I say: > SELECT COUNT(*) FROM mytable GROUP BY myfield; > I get an KeyError 'Unhandeld'. > > SELECT COUNT(*) FROM mytable; > works fine, so does > SELECT myfield FROM mytable GROUP BY myfield; > but not the combination of both. > Also on a linux machine the error doesn't occur.
