Anyone know how to pre-expand a certain branch of a dtml-tree?

Hello: I want a certain branch of my dtml-tree to be pre-expanded whenever the webpage that contains the tree is displayed. My dtml-tree is quite simple; I use the usual subordinate folder structure setup: <dtml-tree single=0 name="catalog" branches="objectValues"> TIA! --Craeg

Does anyone know how to suppress display of +/- signs on a dtml-tree?
by Craeg K. Strong 01 Jan '02

Hello: I want to display a dtml-tree always expanded, with no controls visible for contracting (basically, an indented list of links). I set the tree to always expand via the following: <dtml-call expr="REQUEST.set('expand_all', 1)"> <dtml-tree single=0 name="catalog" branches="objectValues"> But I can't figure out how to remove the little minus signs (-) from the branches. Has anyone done this? TIA, --Craeg

From: "Roy Mathew" <roymath(a)yahoo.com> > How would I use a pathname comprising more than one element in a > dtml-var expression. You put the path to the image inside quotes, and have dots as path separators: <dtml-var "Images.x_gif"> And of course, then you can't use filenames with dots, and no, it won't break any browsers that I know of.

Patch acceptance. What about this one?
by Adam Manock 28 Dec '01

Fellow Zope addicts, I do both name and IP based virtual hosting from a single Apache instance, proxypassing to various different places within Zope. It works great, with or without Apache working mod_ssl magic! Except..... There's a little issue with Zope logging to be solved. Zope logs the IP of the Apache server, not the client. Oops. I might want to track where all administrative logins are really coming from, for example! So I decided to try searching this list before rolling my sleeves up and fixing it myself. Here's what I found: http://www.mail-archive.com/zope-dev@zope.org/msg07600.html Well it appears that Joseph has already solved it for me. Great, gotta love this community. Probably a cleaner patch than what I could have come up with anyway. And I don't have to spend hours digging through the Zope source to get it done! Except... It was written against 2.4.1 I run 2.4.3. It would have been really nice if it had been included in Zope 2.4.next...... Hmm, has anything else changed that I need to be aware of before applying the patch? Lets go to cvs.zope.org and see: First I look at "Diff for /Zope/ZServer/medusa/http_server.py between version 1.26.4.2 and 1.30.36.1". Changes. Looks like some careful inspection of the code and some testing is in store for me. And more porting work next time I upgrade Zope... and next time. I can't help but wonder why something this simple and useful was not just included in Zope 2.4.next? It would have saved me and all the poor fools like me so much duplicated effort... Just another Zope Admin's 2 cents worth...... Adam

xmlrpc and PyXML, FYI
by Brad Clements 27 Dec '01

27 Dec '01

Had some trouble getting strings to unpack because the xml-rpc client I'm using from IE 5 wraps strings in CDATA. Anyway, I installed PyXML 0.7 and changed Zope's xmlrpclib to use from _xmlplus.parsers import sgmlop and that solved the CDATA problem, plus it's faster. This is with Zope 2.5B3 Should Zope include PyXML components?

RE: [Zope] WebDAV or FTP "type"s?
by Derek Simkowiak 27 Dec '01

27 Dec '01

-> Instead of creating a Product, you can just put an External Method in the -> root of your site. A couple of weeks ago, I asked about customizing the default Zope "type" when a file is uploaded with either WebDAV or FTP. For example, I want ".html" files to be a ZopePageTemplate instead of a DTML Document, which is the default. Ron gave me the excellent suggestion of creating an "External Method" that looks like the following: -> def PUT_factory(self, name, typ, body): -> """Make Page Template the default type for ftp uploads.""" -> from Products.PageTemplates.ZopePageTemplate import ZopePageTemplate -> -> if typ == 'text/html': -> return ZopePageTemplate(name) -> return None Since then, I've done some learning, and now I'd like to understand exactly *why* Ron's external method works. I'm creating a Zope Product that will introduce a new Zope "type" called "MIME Remapper". This "MIME Remapper" will be a ZClass that has a single property sheet, which allows you to associate particular MIME types with particular Zope "types" using a nifty text field and dropdown. The problem is, I don't understand why Ron's suggestion actually works. I assume that the method PUT_factory() is over-riding the built-in default, and when it returns None (for an unknown MIME type), Zope --for some magical reason-- falls back to its built-in PUT_factory() to figure out the MIME type. Is that right? Now, does that mean that the only way to override PUT_factory() is via an external method? If so, why is that? If not, can I create a new ZClass that has a method called PUT_factory()? Will a new instance of my ZClass mean that PUT_factory() is overridden for the folder the instance is in? If so, then why is Zope finding the PUT_factory() of my new "MIME Remapper" type when it actually wants the PUT_factory() for the folder that I'm in? Do I need to redefine the PUT_factory() of the instance's folder? How do I do that? Obviously, I'm confused. I feel like this particular problem will give me good insight into how Zope works, so I'd love an explanation of why Ron's PUT_factory() works. (FYI, I understand class inheritance, just not within the Zope framework.) Thanks, Derek Simkowiak dereks(a)realloc.net

List & Dictionary properties; General property handling thoughts
by Eron Lloyd 26 Dec '01

26 Dec '01

This may seem like a redundant question, but this is the third time I've come across the desire to be able to store values persistantly as lists or dictionaries. I've read all the suggestions in the archives pointing out alternatives (<dtml-return expr="{'id': 'item'}">, TinyTable, string.split('value1|value2|..', '|'), "lines" property, SQL DB, etc.) but I still don't quite get the "Zen" of why this wouldn't make sense in practice. People have mentioned that it seems redundant with existing structures like tokens or lines, but these don't seem to have all the familiar benefits of lists and dicts, like instantly accessible mutability and _methods_, plus no added overhead. I know you can manipulate data within lists & dicts in a Python script, but it's just not why I require. Following this thought, I wonder if it wouldn't be handy to be able to cut, copy, & paste properties between valid objects, and provide a way to convert existing property values to different types? Also, the ability to import/export propertysheets of OFS objects could be useful as well (like in ZClasses). The facilities to do these things already exist, so would it be agreed by others in the community to promote these changes? Is it too late to try and work this into Zope3?
