yes, just copy and paste, but i used a follow source and it not work, just work with folders. def candp(fobj, tobj, REQUEST): "Copy and paste" ids = fobj.objectIds() if not ids: return cdata = fobj.manage_copyObjects(ids) tobj.manage_pasteObjects(cdata, REQUEST) anderson > > can you help me ? i need copy a object (dtml document) from a folder >to > > other. > > But what is your problem?

Catalog search cannot sort on a FieldIndex?
by Martijn Pieters 08 Sep '99

08 Sep '99

Hello all, and especially Michel =) Why is it I query the ZCatalog, and have the results sorted on a FieldIndex? Something like: res=apply(cat.searchResults, (), {'sort-on': 'aFieldIndex'}) gives me a AttributeError: items on line 411 of Catalog.py. Maybe I am trying something very stupid here. I have a bunch of objects catalogued with a FieldIndex on a DateTime property. If call searchResults without arguments, it all works beautifully, and the result objects sport my DateTime property. But I want to retrieve these objects sorted on the DateTime property. Note that I want the results sorted by the Catalog, I am not using this in any DTML, so I cannot rely on the in tag's sort attribute. I also wanted to use the more efficient sort results of the Catalog, and the advantages of the LazyCat object.. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

zope + speed + persistant db
by Paul Mokbel 07 Sep '99

07 Sep '99

Hi, I have a few aching questions to ask.. Maybe some of you can bright some light on 'em.. 1) How fast is zope running as ZServer.. (is it fairly fast).. If I use an external python method, and 'import' python modules (if it was previously called), will it reload? or am I confused as to how zope works. 2) Does zope support persistant MySQL connections *THIS IS A MUST!*. Zope, php, mod_perl have some kind of support for persistant SQL connections.. In other words, if a previous connection to a DB was opened and not closed, it re-uses it automatically. It does increase performance.. 3) Does zope use medusa? If not, WHY!?!?!?! (so far, I'd say that medusa is perfect for the operation.. but maybe I'm wrong.. clarify) 4) As per the pcgi CGI wrapper that runs under any other web server: Is there a speed indifference compared to having the ZServer taking care of the http requests.. (pretty obvious, but is it marginal).. 5) To be frank, I am not interested in DTML; rather, I am interested in the python implementation and the possibility of using it for mission critical python CGIs. I previously wanted to implement Python into Boa (a fast httpd, and using it strictly for serving out Python CGI's without the forking of a process). Is this for me? or perhaps maybe httpdapy or pyapache.. I'm looking for performance more than ANYTHING! Thanks! /* "There are two major products that came out of Berkeley: LSD and Unix.

Re: [Zope-dev] Image.py modifications.
by Mauricio Souza 07 Sep '99

I found a function in the image class in Zope2 named "tag". You pass parameters and it converts to img tags in the code like:  = <img src=image height=20 width=20 border=0> this works, but i want that border=0 be a default property in my images...

External methods are reloaded when they are re-edited. If you change an external method and you want to reload it, just click on the method and click 'Edit'. This will reload the actual python from the filesystem. Modules are not reloaded on each hit. Zope is a large system. Confusion is understandable. Brian wrote a brand-new External Method How-To that might help: http://www.zope.org:18200/Documentation/How-To/ExternalMethods > 2) Does zope support persistant MySQL connections *THIS IS A MUST!*. > Zope, php, mod_perl have some kind of support for persistant SQL > connections..

The reasons why are very technical but very good reasons. medusa is a very important component of zope's performance story. > 4) As per the pcgi CGI wrapper that runs under any other web > server: Is > there a speed indifference compared to having the ZServer taking > care of the http requests..

Is this for me? or perhaps maybe httpdapy or > pyapache.. Zope provides more than just DTML, it provides gobs and gobs of very useful framework, including security, object abstractions, rich API, extensibility in several directions, Relation Object Integration, etc... If you don't need any of these things, or if you are going to roll-your-own framework, then don't use Zope. -Michel

Image.py modifications.
by Mauricio Souza 07 Sep '99

07 Sep '99

In my Zope 1 and Zope 2, i do a modification on the Image classes. I created a default property named border with the value 0 and when we call the __str__ function i put the 'border=0' inside the tag. I do that because i want to use the simple <a href></a> without getting terrible blue borders around my image. What you all think about that change to be implemented in future zope versions? -- Mauricio Souza Lima <mauricio(a)hiper.com.br> Hiperlógica <http://hiper.com.br> Automação de web-sites | Website automation São Paulo | Brasil | Fone: +55-11-251-4894

Hello, fellow Zopers - about the CIS..
by Eron 07 Sep '99

07 Sep '99

Greets. I am the developer of the CIS project, and, would like to give a quick notice to all: 1. 1. The CIS project is a project aiming at helping communities everywhere build their own civic networks (there is a report on this at CIS's website). It is very different from anything that might seem to be similar in design. I feel the documentation is coming along well, and a clear understanding of what it is can be gathered from it. Anyone with qustions will be warmly welcomed to contact me (and maybe point out somthing I have missed). 2. 2. The CIS project is NOT competing with Zope in anyway. One of the main things we are interested in is the Portal Toolkit - it seems like a very good design in be incorporated into the CIS. If, somewhere down the road, we are fortunate to extend it's capabilities beyond that existing now, we plan to make the developments available back to the Zope community. Remember, Zope is the CIS's framework, the Portal Toolkit an engine. We are not attempting to replace anything Zope is doing. Zope is good. Zope is great. That's why we chose it, dig? :-) Great, now we are all on the same level. Keep up the good work, guys!! Working for the good of mankind, Eron Lloyd (EarthTone)
