(consuming 100% CPU resources?) or hung? (consuming >none..) Sorry, you're right, it was 'spinning' - 100% CPU resources. Does that suggest anything in particular ? When this first occured, I restarted Zope. That solved the problem for a few hours but problems kept recurring. Last night I restarted the server and since then it has been OK (for the past 8 hrs) ... but I'm anxious how it will stand up to being put under load again today. chas

In a document you could say: <dtml-with "PARENTS[1]"> <dtml-tree ...> </dtml-with> Note that PARENTS is built from the *traversal* path, not from the *containment* path of the object. In other words, B may be contained in the folder A, but it may have been *acquired* from C if it was accessed like /A/C/B. In this case, B's 'PARENTS[1]' is C, not A. -Michel

RE: [Zope] aborting DTML parsing

I think dtml-return will do what you want it to. For instance: <dtml-unless is_a_person_i_want_to_see_this_page> <dtml-return dtMyPageTellingHimThatHeCantSeeThisObject> </dtml-unless> Will show dtMyPageTelling... and will not continue with the script.

Serving files from disk
by Jim Sanford 06 Dec '99

06 Dec '99

If I understand it correctly, Zope cannot serve files (txt,html,doc,jpg,...) directly from disk but can only serve "files" that have been uploaded into the ZODB. If this is correct, are ther any plans to make that capabiltiy available. Alternately, has anyone written an external method that could be used to serve individual files from the filesystem of the machine zope is running on (and any connected network drives)? __________________________________________________________________ Jim Sanford .

Automatically Populating the title Property on html files imported via ftp
by Chris McClimans 06 Dec '99

06 Dec '99

I've been trying to figure out a way to do this and have been banging my head against the wall. The end user still want's to edit the site with dreamweaver but needs the titles to show up in the catalog search. When using the ftp interface you lose properties that have been set, and you have nothing set on new documents. Any suggestions?

We have used Object Domain's 'reverse engineering' as a starting point for out models, but it doesn't work all that well. > I tried to use pythondoc 0.4 without any success. How did it fail, Zope is written in pretty straight up python. Note that some of the classes that Zope classes subclass are extensionclasses (say that 20 times..) that are written in C, your tool may not grok them. > It would be mutch easyer to learn Zope API programming with that kind of docs > > comapred to reading python source. Yep. > Currently afaik only ZODB docs are available (as UML). If every UML tool there is didn't suck so bad we would have alot more UML models, our tool has a propensity for self destructing on its own models, taking the model down with it. For example, there used to be a rather detailed ZCatalog model, but OD messed it up so bad that the OD engineers couldn't even fix it. OD has corrupted the existing PTK model twice, wasting at least an entire week of my time. -Michel Lauri Posti ------------------------------------------ Mutabor DMA, Estonia

But this doesn´t shows in the by Zope produced > html-source. Isn´t this the right way? Nope, but it's not a bad idea, the problem would be seperating valid HTML tag properties from plain straight up properties. Maybe property sheets can address this in the future. For now, use the tag() method on the image object: <dtml-var "image.tag(height=None, width=None, alt=None, scale=0, xscale=0, yscale=0 ..."> The '...' are any other arguments you want to give the HTML tag that represents the image. > Also I mention that after deleting the "height" property I cant add > this again: > > Error Type: Bad Request > Error Value: Invalid or duplicate property id > > Bad Request: (see above) > Am I wrong or is there a bug in my zope installation? Looks like a bug to me. Can you put it in the collector? -Michel

I would think you could just call the ZClass instance like any other DTML Method: <dtml-var myZClassInstance> This doesn't work? If not, what is the error/traceback? BTW, are you getting an error/traceback at some point? -Michel

AtributeError

Hi, When our site tries to access a SQL-server 7 database we get often (not always, it's a bit random) the following error: Error type: AttributeError Error value: tpc_begin --> </BODY></HTML>  When we click on refresh in the browser the page is correctly loaded. We use: NT-server, IIS4, SQL server 7 Zope 2.01 with the latest ODBC adapter. By the way, this problem didn't occur under Zope 1.10 with the old ODBC adapter. Please help, It's verry urgent. Thanks Henny van der Linde
