dtml methods and namespace
by Luca Dall'Olio 14 Mar '06

14 Mar '06

Hi to everybody, I have a simple dtml-method "assignment-action" that is called upon a form post. Depending on the form request data, a <dtml-if> chooses between one of two dtml-documents : "assigment-success" and "assignment-failure" : <dtml-if "iscorrect()"> <dtml-var assignment-success> <dtml-else> <dtml-var assignment-failure> </dtml-if> My trouble is that neither the "assignment-success" nor the "assignment-failure" dtml-documents seem to be pushed on the namespace : inside them title_or_id references data from their caller, this() and PARENTS do not evaluate right... is there a smarter way to call a dtml-document inside a dtml-method (), so that it it pushed on the namespace stack? Should I use somehow the <dtml-with> tag? I understand that page templates would be way easier and cleaner, but I would like to complete this project and then try them out in the next one... thank you in advance, Luca

webdav and PUT_factory
by Luca Dall'Olio 14 Mar '06

14 Mar '06

First of all, I would like to thank everybody for your accurate and fast answers. I am working with a small group of developers, each in different places and working at different times. According to my past experience in java, this means "cvs" ^_^ I have some doubts about how to synchronize Zope development with cvs or subversion. Should I stop using the ZMI? Should I develop a Zope Product instead? Should I use fsdump instead of webdav to export from zope ? Should I use webdav when deploying back to Zope? This is my actual state-of-the-art about team management in Zope : We develop inside locally installed Zope Instances, using the ZMI. At the end of the day, we export the work done using webdav, and this works for DTML documents, DTML methods and ZSQL methods. After that, we commit inside the source code repository, using the update, diff and merge features to synchronize with other developers' work. We need to deploy to a Zope server in order to test the integration of developers' code, so I wrote a little PUT_factory to re-create the right objects, this is a snippet: elif ext == 'zsql': from Products.ZSQLMethods.SQL import SQL return SQL(name, '', 'daticonvegno', '' ,'') elif ext == 'dtml': from OFS.DTMLDocument import DTMLDocument return DTMLDocument( '', __name__=name ) elif ext == 'dtmm': from OFS.DTMLMethod import DTMLMethod return DTMLMethod( '', __name__=name ) elif major == 'text': from OFS.DTMLDocument import DTMLDocument return OFS.DTMLDocument.DTMLDocument( '', __name__=name ) As you can see, it uses extensions to understand the type of the file. This has some minor drawbacks : 1) you have to use extensions to make it work, otherwise you will have trouble at deploy-time 2) some additional parameters such as the connectionIds for ZSQLMethods must be auto-magically chosen by the PUT_factory 3) what about more complex objects, such as Plone, Archetypes or Openflow? should I map them all in the PUT_factory? Is this the "right way" to do things in Zope? Is there any native solution for Source Code Versioning and Team Management? How do other team solve this issue? Any advice is welcome! Thank you very much in advance, Luca

Zope Managed Server
by Dan Gaibel 14 Mar '06

14 Mar '06

Hello Folks, I'm interested in finding a company that will do monthly managed zope hosting. We're looking for a dedicated machine. I know that Zope Corp does this and it is quite expensive. I wonder if anyone has had any experiences with such a service. Any advice is highly appreciated, and I apologize if this list is an inappropriate venue to pose such a question. Thanks! Dan

We have a large application using Apelib right now to persist our zope application onto the filesystem so we can use subversion. It's quite elegant for multiple developers, branching, etc. I'd be interested to know if anyone else has had success with other file system persistence and zope. Most seem to save as blobs (at last our last survey of the options did). Apelib is wonderfull because in most cases it saves the contents in text files which can be accessed by external editors which is how we do all our development now. Diffs and merges are easy plus we get history of changes over time. Because APE doesn't work in 2.9, we are kind of stuck as far as upradeing zope and will need to go to localFS or something like it I guess at some point in the future. I would be curious to know where you come out with this Dennis. -Chris _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

METAL macros
by John Poltorak 13 Mar '06

13 Mar '06

I'm having difficulty figuring out how to make METAL macros reusable. Is it standard practice to put macros into a common folder where they can be used by numerous different websites? I just can't get a handle on how they are supposed to be used. According to:- http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixC.stx Macros provide a way to define a chunk of presentation in one template, and share it in others, so that changes to the macro are immediately reflected in all of the places that share it. Additionally, macros are always fully expanded, even in a template's source text, so that the template appears very similar to its final rendering. This does not really tell me how they should be used. Can someone give me an example of real world usage? -- John
