dtml-tree : branches-expr speed problem
by AM 27 Aug '02

27 Aug '02

Hi, I have a tree node filtering function: ################# root = context.pres_docs_core_files obs = root.objectValues() for ob in obs: if ob.getId() == 'examples' : obs.remove(ob) return obs ################## When I am testing this PyScript it does its work pretty quickly. But when I call it from the dtml-tree tag, it just takes forever to render the tree. It does render it but it takes of the order of 20-25 seconds to do it. Any ideas why?? Also if any one can tell me a better way of implementing the above function (I have no idea how to use a lambda style function or a list mapping function in Python) that would be great...

RE: [Zope] mxDateTime unauthorized
by sean.upton＠uniontrib.com 27 Aug '02

I think I'd agree that mxDateTime is the problem. One way to approach this is to have an external method or utility module that imports mxDateTime and creates a bunch of proxy functions to the various mxDateTime constructors, like: import time #REQUIRES MX DATETIME!!!! from mx.DateTime import mktime def getMXDateTimeObject(timeTuple): """Given a time Tuple, Get MX DateTime object for date-calc and such""" obj = mktime(timeTuple) return obj This accomplishes getting mx DateTime objects without module namespace collision/confusion between the DateTime module in the mx package and the DateTime module in zope. -----Original Message----- From: Jens Vagelpohl [mailto:jens@zope.com] Sent: Tuesday, August 27, 2002 4:48 AM To: Ulrich Wisser Cc: zope(a)zope.org Subject: Re: [Zope] mxDateTime unauthorized remove mxDateTime? jens On Tuesday, Aug 27, 2002, at 07:06 US/Eastern, Ulrich Wisser wrote: > Hello, > > I installed mxDateTime to my Zope 2.5.1.

Even if there were a browser transaction, wouldn't the browser simply note that the URL is local and make a request using the current base. Zope then would have to sort out the proper target URL. The fact that it works most of the time seems to support this view although I have not looked in detail at the code nor at the behavior of the various browsers.

Thanks for digging it out, Oliver. When I get a moment, I'll look at the Zope code and see if it requires an absolute_url for redirection to an internal URI.

Re: uploading images?

> f = *REQUEST.form['attached_file']* > fileContent = f.read() > size = len(fileContent) > > import os.path > head, tail = os.path.splitext(f.filename) > # is it a legal image file ? We dont want users to upload bmp or excel files :-/ > isImage = tail in ['.gif', '.jpg', '.jpeg', '.png'] I saw your solution and I think it has a problem. You're assuming that files have always an extension, but that's not true. What would happen with the Unix and MAC users who are not forced to give the file an extension to know that it's an image? I just tested what happened when importing a "bmp", "gif", or "jpg" without an extension: Zope knows what kind of file it is. I guess the solution is closer to this one: http://www.zopelabs.com/cookbook/992900431 However, it doesn't say if it's a jpg, gif, bmp, etc. But I guess that attribute can be also obtained, for Zope stores something like: image/pjpeg, image/gif, image/bmp, etc. I haven't try it because I don't actually need to do that validation, but I guess it would be nice. Greetings, Josef.

Iterating through object properties
by Kevin Carlson 27 Aug '02

27 Aug '02

Is there a way either in DTML or a python script to iterate through all of the properties of an object without knowing its specific type? For example, if I have CMF Types of Document, File, Event, etc. I want to build a list of all of their properties without knowledge of the particular type. Ideas? Thanks, Kevin

Calling a ZPT on an object
by Felix Ulrich-Oltean 27 Aug '02

27 Aug '02

Hi I have made a python Product and I'm trying to set up its public view. The user can pick (per instance) which template to use from a folder-full of templates. I want the index_html method of my object to call the chosen template with the correct bindings, i.e. here should refer to my object instance. The templates are stored in the root of the site in a folder called "zest_templates/news", and my object has a property called "template" which is the id of one of the PT's in to folder. So, my attempt is below, but obviously it does not work, specifically, the "here" is not bound correctly. def index_html(self, REQUEST=None): """Front-end view of the story.""" return self.zest_templates.news[self.template](self, REQUEST) How can I do this? TIA Felix.

While I delevop extensively in Zope, a local school has asked me to do a class on cmf systems. Naurally I will present Zope, but I also need to tell about other systems. Does anybody know about other systems than the ones I have listed in the bottom? I have intentionally left out Acs as it seems to be fading away. Comments on any of the systems would also be a help.
