You're not quite at ease with this acquisition thing yet, are you? :-) First of all, that should be    (you can also refer to the object as "below.fragment", but this means something slightly different.) Furthermore a generic solution would be    Note that unless you're seeking to explicitly avoiding referring to something in the same directory (for example, the above could be used to build accumulative navigation bars), acquisition solves the problem of referring to up-level objects. -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.

ZServer FTP and aquisition problem
by Alex Rice 19 Jul '99

19 Jul '99

Hi, we just noticed that sometimes with FTP, aquisition can get in the way when recursively uploading folders. This is a problem when a folder by the same name already exists and is aquired. Here is an example from my logfile: 206.183.203.184:2067 <== CWD /taoswebb/import 206.183.203.184:2067 ==> 250 CWD command successful. 206.183.203.184:2067 <== CWD news ["news" was aquired-- it doesn't exist in import/!] 206.183.203.184:2067 ==> 250 CWD command successful. 206.183.203.184:2067 <== PORT 206,183,203,184,128,63 206.183.203.184:2067 ==> 200 PORT command successful. 206.183.203.184:2067 <== STOR taoswebb_masthead2.gif 206.183.203.184:2067 ==> 150 Opening Binary connection for taoswebb_masthead2.gif 206.183.203.184:2067 ==> 426 Error creating file.

Addressing directories below current
by Graham Chiu 19 Jul '99

19 Jul '99

I would like to cut the clutter in my directories, so have tried storing fragments of sql statements in lower directories. Now if the dtml is in the current directory it works fine. eg update main where  but if I try this  it likes it not. ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz

0-day PACK, site gone
by Aaron Rubin 19 Jul '99

19 Jul '99

In the management screen I use PACK and lost everything, I can no longer even manage the server to reload the pages. I thought reloading Data.bbb would restore the functions, but it didn't. Any ideas? I'm working on a remote host. Thanks. --Aaron

Adding documents in Zclasses
by Bill Anderson 19 Jul '99

19 Jul '99

Ok, I've finally been futzin aorund with ZClasses. Wow, these are great! But, of course, I have aquestion. I have a folder-like object that I need to add some things to when created. I can add directories just fin, as well as blank(default) documents by modfying the constructor. The problem is, I need to add documents that have specific content. Such as: --- begin Hello----  <p>Hello, my name is . <p> Would you like to play a game?  ---end Hello-- This does not work if I put the above in the data section of manage_addDTMLDocument(id,title,data). Would I best be served by putting it into a file and then have the constructor upload it? If so, how? Where would it look for the file? Thanks. __ Bill Anderson

RE: [Zope] dtml question: xrange?
by Alexander Staubo 18 Jul '99

18 Jul '99

For this and any other operation not directly supported by the DTML "API", you can write External Methods to provide the service. In this case, a function such as: def XRange(start, stop, step): return xrange(start, stop, step) would do it. -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.

RE: [Zope] Lets try this again - auto-creation

Thread safe yes, but not atomic. In other words, the operation (done in an External Method or whatever) NewObjectId = Counter = Counter + 1 isn't atomic. This is really not of relevance here since only a _unique_ object ID is desired -- I didn't think of that when I said it mus tbe thread safe -- but in cases where you'd want a guaranteed _sequential_ counter, you would risk holes in your sequence as the interpreter thread could be pre-empted at any time during the execution of the statement. Now, I don't know if the Python global interpreter lock permit statements to be interrupted. Does it? In that case, chalk that up as just another moot point :-) -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.

product management question
by Alex Rice 18 Jul '99

18 Jul '99

Why does the "Distribution" tab dissapear when a Product is "installed"? (I think) This makes it difficult to manage products-- if I am working on a project and I want to move it to another Zope installation and then continue to work on it and distribute it again, how can I do this when the Distribution tab is not available? Can I just tar.gz what's in my Products directory? Or do I have to use the distibution tab? -- Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice Current Location: N.

Is there a way to generate a range in dtml? (like the python xrange() function) Specifically, I want to iterate from 0 to a variable (comes from a form) using the #in tag. I couldn't find anything about this in the docs. any ideas? thanks, Kevin
