copy / paste support

When trying to copy an item I get the following item on paste: One or more items referred to in the clipboard data was not found. The item may have been moved or deleted after you copied it. This is a custom python class which is catalogued. Ive no idea why this is happening. Any ideas? -- Andy McKay, Developer, ActiveState http://www.ActiveState.com Programming for the People

Simple(?) Syntax Question (dtml-in)
by Tim Cook 25 Aug '00

25 Aug '00

I want to use the same DTML method for different operations. It gathers info from properties of DTML Documents and returns a list. The list is a list of lists. Each item in the list valid_prj contains a list of two strings, ie. valid_prj = [['abcd','1234'],['efgh','5678']] I want to only provide the first item of each list in this SELECT: ... <dtml-in valid_prj> <OPTION value="<dtml-var sequence-item>"><dtml-var sequence-item></OPTION> </dtml-in> ... But darn if I can get the right combination for the correct syntax to get only that first item of valid_prj.

Re: [Zope] Search on ZCatalog or ZSQL in MySQL

However, most relational databases have difficulties with full text. I doubt, that MySQL can handle it well. The ZCatalog as it is now, is nice for small to medium size content. I, personally, would not use it for content bigger than 50 to 100 MB. Due to some weeknesses in the BTree implementation (which is used by ZCatalog to maintain its indexes) a considerable part of the index structure is rewritten if the index changes. This may lead to a fast growing ZODB with the need for frequent "pack"'s. Before you decide for ZODB, you should make some tests: something like this: * index about 10 MB of content * change content * search with the catalog * index another 10 MB of content (you now have 20 MB content) * change content * search with the catalog For each step: Look how the size of the ZODB changes: before and after packing Look how the main memory requirements changes (especially during indexing) Look how the timings changes (for all relevant operations: indexing, packing, searching) Try to extrapolate your results. You may need to add more 10 MB content chunks to recognize a tendancy. Dieter

simple question
by Marcus Schopen 25 Aug '00

25 Aug '00

Hi there, just a short question about the tree-tag: sould a tree based navigation placed in a seperate frame? I would like to create my sites with tables, so the tree navigation is placed in a table field. I don't want to use frames. The whole page should be in one table. But this seems to give some strange effects. please see: http://marcus.localguru.de:8080/b3/ Or is this normal behavior of a Zope tree? Thank you Marcus ______________________________________ (0> Marcus Schopen //\ Bielefeld, Germany V_/_ ______________________________________

It Works!!!! I think I'm close, Product Creation and other threads
by Daniel Rusch 25 Aug '00

25 Aug '00

Great news, I did it...! The trick seems to be adding the legacy line to the BasicDocument __init__.py file (see below). This allowed the following line to work in the folderish (SimpleSite) product's manage_addSimpleSite function to quit barfing: ob.manage_addBasicDocument(id='index_html', title='') BTW, Remember I said that I my plan of attach, while I was praying for an epiphany, was to figure out how a Folder could create sub products. Well, I figured this out via an epiphany, I accidentally cd'd to OFSP instead of OFS and I looked at the __init__.py file, it was most illuminating..... Ok it wasn't exactly an epiphany, but I'll still chalk it up to divine intervention.... DR This is the __init__.py file for the folderish product which contains the other product I created. __doc__="""SimpleSite product initialization""" __version__='$Revision: 0.1 $'[11:-2] try: import os, SimpleSite from Globals import ImageFile def initialize(context): context.registerClass( SimpleSite.SimpleSite, constructors=(SimpleSite.manage_addSimpleSiteForm, SimpleSite.manage_addSimpleSite), #icon='simpleSite.gif', legacy=(SimpleSite.manage_addSimpleSite,), ) context.registerBaseClass(SimpleSite.SimpleSite, 'Simple Site') except: print "She's sucking mud in SimpleSite land capt'n:" import traceback traceback.print_exc() This is the __init__.py file for the other product: __doc__="""BasicDocument product initialization""" __version__='$Revision: 0.1 $'[11:-2] try: import os, BasicDocument from Globals import ImageFile def initialize(context): context.registerClass( BasicDocument.BasicDocument, constructors=(BasicDocument.manage_addBasicDocumentForm, BasicDocument.manage_addBasicDocument), #icon='basicDoc.gif', legacy=(BasicDocument.manage_addBasicDocument,), ) context.registerBaseClass(BasicDocument.BasicDocument, 'Basic Document') except: print "She's sucking mud in BasicDocument land capt'n:" import traceback traceback.print_exc() Chris Beaumont wrote: > > Daniel, > > Would you let me know if you get a good answer to your question..

ODBC Bridge / SQL Server stuff
by Phill Hugo 25 Aug '00

25 Aug '00

Hello, Easysoft (www.easysoft.com) supply a simple, efficient SQL bridge which works well with unixODBC (.org) and iodbc (.org) driver managers. We use it on one of our PHP sites to link to an SQL Server db from Linux. It works fine but its a close product. So given the easy of use of XML-RPC or SOAP from Python, it may be sufficient to create your own bridge which calls a remote DB connection made with ASP or Zope on NT. I've set this up with a Python method calling a remote DB connection in PHP using XML-RPC (just pass the query over and get the records back) and it works perfectly. Hope this helps. Phill

Small Tip
by Maik Roeder 25 Aug '00

25 Aug '00

Hi ! It always got on my nerves that I needed to change the column size of the DTML Method and DTML Document Edit Forms manually by pressing "Wider" and "Narrower". Instead of patching the Zope source code, I found the following a good approach: Define a property in your root folder: id: dtpref_cols type: int value: 80 The magic of acquisition does all the rest ;-) Greetings, Maik Röder -- "The computing future is based on "cyberbodies" - self-contained, neatly-ordered, beautifully-laid-out collections of information, like immaculate giant gardens."

Microsoft SQL Server Access under Linux?
by Darin Lee 25 Aug '00

25 Aug '00

Zopistas, Is it possible to access an ODBC data source through Zope running under Linux? I have perused the literature, and it appears the Zope DA's for ODBC only run under the Win32 environment. I would very much like to setup ZAP (for many reasons), but our "organizational standard" is MS SQL Server 6.5. Thanks, -Darin Lee Darin M.
