Re: [Zope-dev] External Method Missery

These are all methods, and therefore you'd expect the "self" object to be the object the methods are subobjects of. The exact turn of events is that index_html is a DTML method which shows a DTML _document_ with dtml-var doc_name The header, in which the navtree is rendered, is a DTML method that's called from the doc_name DTML document with another dtml-var navtree is a DTML method which calls the external method. So unravel all that, and you can decide for yourself ;-) See my reply to my own posting which poses another interesting question.

Thanks. The proxy roles stuff is for Generic providers and triggers, so that when they execute your expressions they can have roles other than those of the current user, which is important for constructing secure applications. The local roles stuff is the ability to have a DataSkin get local role information from "local role providers", thus allowing rules-based local roles to exist/co-exist with the standard Zope persistently-managed local roles. One aspect that will be considered in the local roles work is adjusting the LoginUser class so that it can use more efficient ways of checking access to an object if it's a DataSkin. The built-in Zope approach has to look for *all* local roles that a user has, even when it only wants to know about one of them. In general I'd like to see Zope's local role API's tightened up in this fashion. Another tightening would be to use the user object rather than the user's ID or name when calling local-roles API's, since a rule-based approach may need to consult data on the user object. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] ZPatterns alpha 5 released
Here's the details from the CHANGES file: New Features/Bug Fixes in 0.4.0alpha5 - Property Sheets for DataSkin-based ZClasses. Now you can put define property sheets on a ZClass and still use AttributeProviders for the properties. Just add a "DataSkin Property Sheet" to your ZClass instead of a "Common Instance Property Sheet". (Note: you can only do this with *new* DataSkin-derived ZClasses. If you have an already existing ZClass, you must either re-create it by hand or do the "setbasesholdontoyourbutts" hack to re-create the ZClass.) - GenericTriggers now also pass a variable "ORIGINAL" which is a dictionary of the original values of changed attributes (or NOT_FOUND if the attribute did not exist before changing). Note that if the values are complex or mutable, they cannot be guaranteed to be truly the same as their starting state, so this should really only be used for simple atomic values like strings and numbers. - Numerous bug fixes, including: - Specialists were always returning the result from the first Rack - setuid support for LoginManager was broken, and also didn't deal with executable-owner masking - _DelAttributeFor() was broken for persistently-stored attributes - Deleting a non-existent attribute no longer flags the attribute as changed - _constructPlugIn() was broken with latest 2.2 version that binds constructors to their products/factories - In the latest Zope, setting ownership after adding was causing a Changed event to fire instead of an Added event. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

I used to write: data=self.which_one and self.second_data or self.first_data but this failed because sometimes self.second_data is a "false" value (eg 0, '', instead of None that I use for empty values), causing self.first_data to be returned instead. one learns about python every day. thanks for the tip.

But without knowing what your app is actually trying to do, I can't suggest anything further. I'm writing an application to track issues. I can not just use DC's tracker product, because my customer's needs are very specials. Well, various entities in my application have a so called 'location'. I wish to be able to re-use the application I'm writing, so I abstracted the concept of 'location'. i have then a specialist to manage locations got from a location rack. The rack I wrote for my customer deals with two-headed locations: (site, subdivision). Each part of the location is managed in a different way, but I need the two to identify one's location. Later, when I install that program for a different customer, I want to be able to rip out the old location rack and put another location rack which can be more 'normal' (ie, one-headed) No one will notice except the key to get the location is now an integer (or a string) instead of a tuple. So, I think I'm doing right to have an id which is a sequence. Thanks for your great help.

Re: [Zope-dev] zpatterns: how to specify default values?
"Phillip J. Eby" a écrit : Yes. Name the attributes "class_default_for_X" where X is the attribute name. Thanks very much. This works with the currently release ZPatterns, but alpha5 will go one better and let you create ZClass property sheets that transparently implement this. That is, if you add a "DataSkin Property Sheet" to your ZClass instead of the standard "Common Instance Property Sheet", that sheet's attributes will be translated to/from the "class_default_for_X" names on the ZClass. I don't use ZClass as I wrote only in Python. I really have to understand how do propery sheets work. What I don't understand is where the properties are stored. This is not clear when I read the PropertyManager source. I guess property sheets are for grouping some related attributes, but the actual work of storing/retrieving the attribute is done by the attribute providers, right? If so, so be it :-) By the way, - is the python programmer have to mix PropertyManager in with DataSkin to use property sheets? I guess so, but what, I seem to be the only one who use zpatterns directly from python. All the ZClass junkies out there do have all the mixin classes ready even before they start :-) - I sometimes have a dataskin that is willing to get something from its context. What is the preferred way to do this: try to acquire the attribute from self._v_rack, wich is guaranteed to be wrapped in the specialist's context, or just mix Acquisition.Implicit in with DataSkin? regards, [EMAIL PROTECTED] ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

that is suppose to be displayed currently
the main dtml file has the following
line
dtml-var SomeVar !-- there is a valid namespace SomeVar and this line
prints it out... --
!-- the next line works fine with
Number 5, but not if I substitute SomeVar instead of 5 --
dtml-var "Some_Header(style=Some_Style_css(SomeKey=5))"
-
the Some_header dtml file has the following
lines-
style
--!
dtml-var style
--!
/stile
-
the Some_Style_css dtml file has the following
lines--
input{ position: relative;
font-size: dtml-var SomeKey
}
--
Now the whole thing works great.. however, if I attempt to make NUMBER 5
by any variable from REQUEST or the current form
the KeyError comes up : if instead of 5 I put SomeVar (which was
passed to this dtml from some other form) I get "Error Type: KeyError Error
Value: SomeVar"
