Managing subobjects
by Menard.Jean-Francois＠hydro.qc.ca 15 Aug '00

(I speak frech, sorry for my english!) I created a ZClass, zRow. This class can contain other ZClass: zField_Text, zField_Date, etc. This let me define the columns contained in a zRow. I then defined a Class zTable, wich contains zRows. Question: - In my manage tabs, I needed a have a tab "Define columns". Do achieve this, I inserted a ZRow Instace (with id Definition) in my zTable product definition, and a method called Define_Columns, containing: <dtml-with Definition> <dtml-var manage_main> </dtml-with> And I defined a view "Define Columns" pointing to that method. When i click on the "Define Columns", I can see the manage screen of the instance "Definition", that's what I wantwd. But when Add a zField, the instance is create in the zTable level, not IN Definition instance! All the classes are Based on CatalogAware, ObjectManager. Any ideas how to fix that? Any sugestion how I could implement this?

I've created a product, installed it and it appears on the Product Management at /Control_Panel / Products list. The question is how do I get it to appear in the drop down of Available Objects? Dan

Jean Jordaan writes: > ... anonymous user despite authentication .... > (this is from ccDocClass_add). When I arrive I *still* see: I may be a cache issue as suggested earlier in the list. However, I may also be a Zope feature. When you access an unprotected object, Zope may not determine the "true" authenticated user but simply return the anonymous user object. This is nasty, if user objects have additional properties or additional roles that are inspected in an unprotected page. Dieter

Re: [Zope] speeding up dtml-tree

The tree tag itself does not cache. You could implement your own cache in your external methods. We extended the tree tag with a "has_branches" argument. If present, it should be a method that tells for the current object whether it has branches (aka children). This reduced the number of database accesses (where our tree data really lives) by an order of magnitude. In principle, I could give you (or the community) a patch for "has_branches". Unfortunately, we extended the tree tag quite drastically (configurable icons, "has_branches", "input type=image" instead of "a href" tags for tree operations). Thus, the "has_branches" extension comes embedded in a big patch that may not be easy to understand. Dieter

The "why" is only my guess: support for the widespread idiom "<dict>.items()", "objectItems" etc. Form the DTML reference: sequence-key The key associated with the element in an items sequence. An items sequence is a sequence of value pairs that represent a mapping from a key to a value. Dieter
