You can use this to render DTML on the fly, as you wish.
I guess it would be better to allow constructs as:
dtml-var "table('main','col')"
dtml-var "font('standard')"Some text/dtml-var
/dtml-var
Where 'table' and 'font' are PythonScripts that return the implicit blocks passed to
them (these blocks may have a default variable name in the expression's namespaces)
enclosed by the correspondent html blocks, with the format ('main, 'standard') mapped
to html attributes/values using some dictionaries. This could help to separate logic
and presentation in dtml code with a minor syntax addition.

Re: [Zope-dev] DTML Documents/Folders in ZClasses fail to accessanything

Thanks, but it's got nothing to do with getId... I just used id because it's easy to write. I get the same behavior if I try to view meta_type, or a property that is defined on a propertysheet in the ZClass. And the fact that the DTML Document uses its own attributes shouldn't cause Unauthorized, should it? It should just show a different attribute, or acquire the attribute if it doesn't have it. I just tried it again with a clean install of Zope 2.3.0. In a DTML Document, this works (name is a property in the ZClass propertysheet): dtml-with "PARENTS[0]" dtml-var name dtml-var meta_type /dtml-with But these fail with Unauthorized: dtml-var name, dtml-var meta_type. The dtml-var title_or_id in standard_html_header fails as well. I also repeated the folder test: In a DTML Method stored inside a folder in the ZClass, dtml-var name works, but dtml-var title_or_id fails. So what do we have? I can't use title_or_id on DTML Documents, so it's useless for use in standard_html_header (and title_or_id uses getId, so it should work). I can't access ZClass properties from the DTML Document unless I use dtml-with - meaning no acquisition. And I can't access properties of the DTML Document (like meta_type) unless they are accessed using a method call (like getId()). This can't be right. I find it hard to believe that if this is really a bug, it didn't bother anybody else until now. On the other hand, these tests seem to show a problem with security checks on objects in ZClasses that create their own context. So what am I still missing here?

Example, What's the different between:
searchResults(used=(index1,index2), index1='kalle', index2='kaviar')

Damn, where's this documented?
I think this is _exactly_ what I've been looking for for ages, especially, I'm
guessing, that if you don't specify 'used' then:
1. It's assumed all indexes take part in the search
2. All parameters that aren't supplied are assumed to be blank, and therefore
will match anything?
Am I on the right track?
Furthermore, is there any way I can tell ZCatalog that nothing means nothing,
not everything?
For example, if I do searchResults(age=''), I want only records with a blank age
record, _not_ all the records.
Okay while I'm here, one final one.
We have the sort_on and sort_order parameters, they'll return stuff ordered
like:
Aardvark
Badger
anteater
bird
Whereas most humans would think the following would be more readable:
Aardvark
anteater
Badger
bird
I guess ZCatalog uses cmp somewhere along the line. IS there any way I can pass
in a different cmp function for a given index?
Hah, just thought of one last one ;-)
Okay, we have sort_on, which lets me sort on one index. Is there any way I can
provide a secondary sort key?
something like
searchResults(age='',sort_on=(('lastname','normal'),('firstname','normal'),'('salary','reverse')))
would eb a dream.
Wow, that turned into a ZCatalog wishlist... any ideas if any of it is
available, and if not, hwo hard it would be to achieve?
cheers,
Chris

There is no practical difference, unless you are "federating"
queries across multiple catalogs; the 'used' parameter is there
solely to accumulate a record of the indices used in the search.
(Are used supposed to be a tuple?)
It should be something supporting the mapping interface. Here is
how it is used (from 'lib/python/Products/ZCatalog/Catalog.py'):
if used is None: used={}
for i in self.indexes.keys():
try:
index = self.indexes[i].__of__(self)
if hasattr(index,'_apply_index'):
r=index._apply_index(args)
if r is not None:
r, u = r
for name in u:
used[name]=1
In other words, "Nothing to see here; move along." :)

Since I had ExtFile and ExtImage I chopped those into one class called it ExtThing, and the wrote classes off it. ExtFile and ExtImage I cut and pasted (not complete) for the most part. Then I wrote a class that called ExtHTML that is a DTML Document that overrides the munge() and read() read functions. Instead I passed those onto ExtThing. And there you go a DTML Document that has the main body stored on the local file system.

Well sort of, the idea was sparked by ExtFile (yes its all his fault honest). We want to have files on the file system for many reasons which I won't go into now, just take it for granted. But we also want some of the objects information to be in the standard data.fs, so we can catalog it use acquisition provide a simple interface to it and so on. So far you are saying thats ExtFile and you are right. But we want to extend it to any object anywhere, instead of storing the data attribute in the object and pickling it in the ZODB I want to be able to store the data attribute on the file system. This gives us loads of advantages we also thought this would be extremely useful to other people. We've bounced around ideas on how to do this and here the only two so far: -we could overload the data attribute with a class that on Pickling into the ZODB instead writes it on to the filesystem... -we could in the ZODB put a hack to say if pickling something with so and so attribute do this instead... I feel like this something I should just not be doing, but it would be great if I could get it work... -- Andy McKay. ___ 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 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 ) -- . . . . . . . . . . . . . . . . . . . . . . . .

Re: [Zope-dev] initializing objects in ZPatterns
Hi! To get company_address stored, you can probably do something like: your_object.manage_changeProperties(company_address=your_object.company_address) or possibly your_object.propertysheets.NameOfSheet.manage_changeProperties... depending on what kind of object you're using. I've now tried WHEN OBJECT ADDED CALL self.propertysheets.data.manage_changeProperties(company_address=self.company_address) which gives me some Unauthorized error on the method call. (when doing it manually in some dtml method after newItem() it works ok, though. And I am logged in as Manager..) Sometimes I wish Zope would print more about the details of such an response, e.g. which permissions might be missing.. Anyway, I will keep experimenting with it (also tried to subclass directly from DataSkin, to override some method which create the company address) but then I noticed that it always needs to be a ZClass (except I would also implement my own Rack, I guess..) Wonder when the basic app will be running.. ;-) ok, nice evening everybody! :) -- christian ___ 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 )

Re: [Zope-dev] ZCatalog Lazy Results

You can batch large result sets: "getObject" would just be applied to the objects in the batch. The objects are cached, too (ZODB cache).

For instance, the following construct: dtml-bvar "foo(a=1)" var="block" some text dtml-var "1+2" /dtml-bvar would invoke the expression "foo(a=1)" with a variable named 'block' set to 'some text 3' in the expression's namespace (btw, is it possible to achieve this using regular dtml?). What a construction! I do not like it. However, I couldn't find a way to set a variable in the namespace used in the evaluation of the expression.
