ZWiki with Zope 2.7, OS X Server 10.4.x
by baiewola 22 Jun '06

22 Jun '06

I installed ZWiki by unpacking and putting the folder into my Zope Products directory. I restarted Zope and ZWiki shows up as a valid product. However, when I actually try to add a ZWiki from the "select type to add..." pulldown menu, I get this error: Time 2006/06/22 09:05:41.911 GMT-4 User Name (User Id) Anonymous User (None) Request URL https://myserver.com/zope/manage_addProduct/ZWiki/manage_addwiki Exception Type NotFound Exception Value https://myserver.com/zope/manage_addProduct/ZWiki/manage_addwiki Traceback (innermost last): Module ZPublisher.Publish, line 91, in publish Module ZPublisher.BaseRequest, line 335, in traverse Module ZPublisher.HTTPResponse, line 630, in notFoundError . . . (The rest of the error shows HTML tags and the REQUEST object.) I didn't find anything on zwiki.org about this issue, and I tried Googling with no success. If you have experienced this issue, would you please tell me how you fixed it? Thanks! - B __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

ExternalMethod for exporting un-pickled Office files to the filesystem etc
by michael nt milne 22 Jun '06

22 Jun '06

Hi Just wondering if anyone has written or attempted to write a script which would read through a site built using Zope and write all attached/uploaded files (Word, PDF, Excel) etc to a filesystem location in an un-pickled format. Therefore the files would be usable by their native application and be accessible outside of Zope. The business logic behind this is to be able to create, say once a day at night, a copy of all digital business assets for extra back-up and recovery purposes in case of disaster. Also this would be good for migration purposes if required. If not, how long would it take to create such a script? I could probably source a sponsor for it. I realise that it's best to do this at the application level and at the moment this would be through Plone. I've demoed all the Plone external storage products and also checked out DirectoryStorage but all these store pickled files etc. Thanks -- michael

Need prof. tool for conversion html->pdf
by Tomasz Bielecki 22 Jun '06

22 Jun '06

Greetings to all, my company is searching for a tool capable of producing good quality pdf's from page templates or documents on the fly. This tool should somehow integrate with Zope. It could be Zope/Plone product, python script or even shell script invoked by Zope. It can be commercial (and probably will be). I've searched the net, but found nothing that would met this requirements: * professional css conversion: pdf should look almost exactly like source document, all css properties should be handled * it should omit silently html elements, that are not supported (e.g. flash objects, applets) without crash or error * links should be active (clickable) in pdf * conversion of html forms to pdf forms would be nice to see * conversion from flash objects or java applets to static images (somehow) would be nice to see too * even putting flash objects into pdf was considered (i'm suspecting latest pdf format handles build-in flash, since adobe bought macromedia some time ago) Every help that i can get would be appreciated. --

how improving dtml-in nested?
by mbr 21 Jun '06

21 Jun '06

i have two dtml-in nested .... <dtml-in ZSQLMethod> <tr> <td>&dtml-field1; </td><td>&dtml-field2; </td> <td> <select> <dtml-in AnotherZSQLMethod> <option <dtml-if expr="anotherfield1==field3">selected</dtml-if> value="&dtml-anotherfield1;">&dtml-anotherfield2;</option> </dtml-in> </select> </td> </tr> </dtml-in> .... but they are many calls to AnotherZSQLMethod. So I am trying this <dtml-let RS=AnotherZSQLMethod> <----return results to one variable <dtml-in ZSQLMethod> <tr> <td>&dtml-field1; </td><td>&dtml-field2; </td> <td> <select> <dtml-in RS> <option <dtml-if expr="anotherfield1==field3">selected</dtml-if> value="&dtml-anotherfield1;">&dtml-anotherfield2;</option> </dtml-in> </select> </td> </tr> </dtml-in> </dtml-let> i think this is more quick Check data in memory (variable RS) what a ZSQLMethod. But is real. RS is a result of ZSQL or a instance? ps. Sorry for my english. -- Lo bueno de vivir un dia mas es saber que nos queda un dia menos de vida

load balancing ftp over ZEO clients
by Reinoud van Leeuwen 21 Jun '06

21 Jun '06

Hi, We have an intranet that has a ZEO setup. For http and webdav there are even fronproxies installed which are loadbalanced though a Alteon server. (yes it is kind of an overkill setup but we wanted to get some experience with such a setup for future projects). We now would like to rollout ftp acces for the users that cannot use webdav for some reason. Has anyone experiences with load balancing ftp over several ZEO clients? What are the todo's and todont's? Can I forward both port 20 and 21 to the ftp port of the ZEO? Is it possible to use passive and active ftp? Thanks, -- __________________________________________________ "Nothing is as subjective as reality" Reinoud van Leeuwen reinoud.v(a)n.leeuwen.net http://www.xs4all.nl/~reinoud __________________________________________________

Refreshing zope2 product
by Peter Bengtsson 21 Jun '06

21 Jun '06

In case you've missed this, I've written a little quick article about how I refresh my zope products when developing product code. http://www.fry-it.com/at/refresh-my-zope-products I know that this might be a personal preference but consider how many people who still use zope-restart to test changes I think this is worth a shot. -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

How to commit a piece of data in a transaction when the transaction is being aborted later
by William Heymann 21 Jun '06

21 Jun '06

I am dealing with a zope system where Verisign is sending a POST to our server for ecommerece purposes. Currently I am writing the entire contents of the POST from verisign to the ZODB however I have a problem that some of these POSTs are not being recorded because an error occurs later in the transaction. What I would like to do is isolate this recording from everything else. So that no matter what other error is raised that part will commit so I have a record of the conversation later. Currently I can put the logging step as the very first step in the conversation with verisign and call get_transaction().commit() (I am currently using zope 2.7 and working on the migration to zope 2.9) What would be the best way to deal with this problem? Should I just do a commit of the transaction as the very first step so that part is written and then zope will start a new transaction for the rest of the stuff done? Should I somehow tell zope to run a certain function as its own transaction? Also when I switch over to zope 2.9 how will these things need to be changed? Thanks
