Re: [Zope3-Users] Expressing n:m relationship in ZODB
Leonardo Rochael Almeida wrote: In usual Object Oriented modeling, an n:m relationship is usually modeled as a collection of relationship objects each one keeping one direct reference to each side of the relationship. Of course, using these systems that already try to model relationships helps you not to reinvent another wheel. I think I understand. So if I would like to reinvent another wheel, just for the educatinal purpose, I should do it like this: If I have IArticle and IProject which should have a relationship, I would introduce IArticleProjectRelation which holds a reference to the related objects. These relation objects will be managed by an IArticleProjectRelationManager which has an interface like: relate(article,project) unrelate(article,project) get_related_articles(project) get_related_projects(article) In that case, IArticleProjectRelation would be an implementation detail of IArticleProjectRelationManager and I do not have to expose it at all. And in Zope 3 terms, I would implement the manager as a local utility. Right so far? If yes, I could add helper methods to IArticle and IProject which encapsulate the access of the utility to hide this detail from the user. Would you do that? Or has it some drawbacks which I don't see yet? thanks for your help, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Expressing n:m relationship in ZODB
Hi, there was a discussion about the bad idea to simulate a relational database in ZODB using indexes and unique ids. So I wonder what's the "correct" way to express a n:m realtionship between objects. For example: I have projects and articles. An article might be relevant for multiple projects and a project might have multiple relevant articles. Could I simply give each object a list containing the related objects?

Hi, I searched for informations about Zope and IIS. It seems that this was a problem with Zope 2 and older IIS versions. I don't know much about Zope 2 but with with my Zope 3 knowledge I guess this should be easier for Zope 3 and an IIS running Asp.Net. Implementing an IHttpHandler in C# which forwards requests to Zope 3 should be much easier than implementing a ISAPI filter in C++ in "the old days".

Skins are one of the few Zope 3 concepts I was able to implement quickly. All sources will assume that you understand TAL, and METAL. You can download the source from either book either of the Zope 3 SVN or the worldcookery site. Thanks for the hint. I'm learning Zope mainly based on Phillips book. The book is very good, but the skinning example was too short for me. ;-) But together with the online version of the "Zope Developer Book" I was able to figure out how to skin my app. regards, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Skinning in Zope 3.3
Hi, I try to understand how to customize the look & feel of my page using the new skin/layer implementation of version 3.3. I followed the example on http://www.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/SimplifySkinning but still don't understand on how to change the layout of my page. Could somebody provide a short hint on how to override @@standard_macros/page for the ShanghaiSkin in the example above? regards, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Zope, WebDAV, MS Word
Hi, I'm able to connect from Windows via WebDAV to a Zope instace and can read the content of my zope objects. But I'm not able to edit the files, because all files are opened read-only. I have tried MS Word and OpenOffice. Both show the same behavior. Searching the web, I found some old postings by Andreas Jung which state that the "read only" problem has been fixed in Zope 2.x!? Is there still a problem with Zope 3, WebDAV and Windows? Any hint how to edit objects via Microsoft Word or OpenOffice Writer? regards, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Integrating text indexing engine into Zope 3
Hi, I want to integrate support for a specialized text indexing engine into Zope 3. The engine is able to provide documents which are "similar" to a reference document. First I had a look at ICatalog, but IInjection seems to be the way to go. Could somebody give me a high level overview on how to use / implement these interfaces? I currently think about the following steps: - Implement the index as local utility. - Define an interface IMyStorageDocument for documents to be stored in my index. - Capture somehow if objects are created or deleted. Check if the object can be adapted to IMyStorageDocument. If yes, store it in the index or remove it. Clients then only have to implement an adapter for documents which should be indexed. To search for documents one could access the index as local utility. I'm still a Zope beginner and would be happy to have some guidance into the right direction. regards, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Debugger for Zope 3
Hi, could somebody recommend a good visual debugger (not pdb) which can be used with Zope 3? I would like to start Zope 3 with the debugger, set some breakpoints in my modules and step through the code to learn more about Zope. regards, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Understanding authentication
Hi, I have created a folder "main" below [top] and converted it into a site. I added a PAU to the site management folder and a Principal Folder to the PAU. I registered all utilities. Then I created a new principal "demo1" and after that a new subfolder below "main". I switched to the subfolder and granted management and view permissions to "demo1". But I'm not able to login as "demo1"!? If I add "Session Credentials" utility to the PAU, I get an endless loop which tries to redirect to a login.htm. Using "Zope Real Basic-Auth" the login simply fails. Is there a simple example on how to setup a sub-site with a PAU and to allow login to a principal from this PAU. regards, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Concurrent data access in Zope
Hi, I have a questions about concurrency, which came up during switching my head from realtional databases to ZODB: I think about implementing a container-like data object which holds other data objects. To speed up access to the child objects I would implement some indexes using persistent btrees, which are managed and stored by the container object. How is access synchronisation to such a structure handled in Zope? What happens automatically? What do I have to do on my own? regards, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

You can either grant permissions to principals (or groups/roles) globally. Those permissions can be used in multiple ways: * To protect Views. You can only access views you have permissions for (e.g. ) * To protect attributes/methods of classes (*not objects*) () * To define, who is allowed to modify certain attributes ( ) I can follow to this point. That's how I understand Zope security until now. Additionally you may grant permissions (and role memberships) on a per object (*not per class*) basis ( using e.g. the grant.html-View) which effects only a single object. That's what I was looking for, but don't know how to do. For I example: I want to let a user create an object (i.e. a message in a message board). All users with a certain role (i.e. Admins) should be able to edit the new object, but the creating user should also be able to edit it. So I have to give him the persmission to edit. How can I do something like that? regards, Achim ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
