RE: [Zope-dev] Emailing html web pages: how can I render page as the anonymous user?
by Bjorn Stabell 07 Oct '01

My favorite way is to support this is to create skins. We have two skins: printable emailable that fixes the standard_html_* stuff, and can even be used to override the content rendering at a deeper level, if needed (overriding document_view etc). We can use the same way to support WAP, Avantgo etc also. A printable version of a page is simply done by doing http://myurl/contenturl?portal_skin=printable Pretty cool. IMO, this is a better use of skins than to use it for languages; languages are better managed by Localizer or ZBabel.

RE: [Zope-dev] Product Icon
by Adrian Hungate 06 Oct '01

06 Oct '01

If I understand what you are trying to do correctly, then all you need is to have your product's icon property be a method that returns the path to the correct icon (Like you would normally have the icon property set to). I use this for a couple of products too. Something like: class MyClass(.... normal stuff ...): """ """ def icon(self): """ """ if self._i_am_broken_: return "misc_/MyProduct/MyClassBrokenIcon" else: return "misc_/MyProduct/MyClassNotBrokenIcon" You've got to love python :) Adrian... -- Adrian Hungate Try Zope - http://www.zope.org - You might like it.

One of the properties is the path to another Zope object. Then methods are defined like getObject(), getPath().

It allows one group to add a news document in their folder and if another group would like that news item to show on their site they can create a reference to it. Anyway, what happens from time to time is an object is referencing another object when it gets deleted/renamed/moved and that breaks the reference.

ZCatalog API
by E. Seifert 05 Oct '01

05 Oct '01

Hi list, as I'm not very familiar with the internals of ZCatalog I have a question to all you API experts: Why does ZCatalog.py (under Zope 2.4.1) specify a 'addIndex' permission for a method called 'manage_delIndexes' although there is no such method? The only method I could find to delete Indexes is 'manage_deleteIndex'. Can anyone comment on this? TIA Erich

Curious problem with comprehensions and PythonScripts
by Steve Alexander 05 Oct '01

05 Oct '01

Here's the situation: I have a dtml document with a list of questions under various headings, formatted like this: HEADING 1 question1 question2 question3 HEADING 2 question 4 question 5 I have a PythonScript that gives a list of only the questions to a Page Template: PythonScript called get_questions: data=container.data_document(None, None) # ignore blank lines # lines with no leading space are headings # lines with leading space are questions return [l for l in comps.splitlines() if l if l[0] is ' '] I'm rendering this using a page template: <td tal:repeat="question container/get_questions"> The problem is, I'm often (always?) getting no questions rendered. However, if I change the python script to this, it works every time. PythonScript called get_questions: data=container.data_document(None, None) # ignore blank lines # lines with no leading space are headings # lines with leading space are questions questions = [l for l in comps.splitlines() if l if l[0] is ' '] return questions Any ideas what might be happening? I think the compiled code of the python script might be incorrect when directly returning the results a comprehension. -- Steve Alexander Software Engineer Cat-Box limited

Random.shuffle
by Steve Alexander 05 Oct '01

05 Oct '01

Any particular reason why you can't use Random.shuffle from a PythonScript? Or any other methods of a Random object. I'd like to propose that restricted python be allowed access to methods of random.Random. I know that I can write a product to add a security declaration to random.Random, but I'd like this to be enabled by default in Zope. -- Steve Alexander Software Engineer Cat-Box limited

Building a WebDAV capable product: how?
by Raymond Penners 05 Oct '01

05 Oct '01

At work, we are seriously considering using Zope. For the Web front-end, we are already sold. However, for our use, we will heavily rely on its WebDAV services. We'll need to do some special tricks, so that legacy systems and Zope interoperate nicely. As a test case, I wanted to see what it takes to create a special product, that appears as a directory in webdav, offering some dummy objects. I want to do this programmatically, not using ZClasses, nor using the Zope management interface. For my test case, I really just want to (ab)use Zope's WebDAV server functionality. Using the "A minimal product HOWTO", and inheriting from webdav.Collection a webdav directory appeared quickly. However, I am a bit stuck at figuring out how to get some dummy objects in there. Modifying the "self._objects" doesn't seem to help, and any documentation on the ObjectManager, and how it relates to FTPList/WebDAV is rather sparse. What I have so far is appended below. Thanks for any Zenlightenment! --8<--8<--8<--8<--8<--8<--8<--8< from OFS import * import webdav import OFS from OFS import FTPInterface class duologix( webdav.Collection.Collection, SimpleItem.Item, ObjectManager.ObjectManager, FTPInterface.FTPInterface ): "duologix object" meta_type = 'duologix' isPrincipiaFolderish=1 def __init__(self, id): "initialise a new instance of Duologix" self.id = id def index_html(self): "used to view content of the object" return '<html><body>Hello World</body></html>' def manage_addDuologix(self, RESPONSE): "Add a Duologix to a folder." self._setObject('duologix_id', duologix('duologix_id')) RESPONSE.redirect('index_html')

COPY/PASTE problem
by Johan Beauce 05 Oct '01

05 Oct '01

Hello, I would like to copy and paste file in my site. I created "copy button" with this code : <dtml-let objCopy="_.getattr(PARENTS[0], idChk)"> <dtml-call expr="objCopy.manage_copyObjects([idChk])"> </dtml-let> this code don't make an error, but I'm not sure that's work! I suppose that "manage_copyObjects()" reference the file in the clipboard, but how can I use the function "paste", maybe like that but it doesn't work ... <dtml-let objPaste="_.getattr(PARENTS[0],)"> <dtml-call "objPaste.manage_pasteObjects()"> </dtml-let> how can I view the content of its clipboard ? thanks, Johan.

ZTables and/or Catalog plugable brains?
by Jay, Dylan 05 Oct '01

05 Oct '01

(resent to here from zope(a)zope.org due to complete lack of resoonse. Perhaps there should be three levels of mailing list. zope-use, zope-app-dev, zope-dev or something) I'm in the process of of write a zope product that will deal with a lot numerical data (records with a few ids and a few float values). Rightly or wrongly (comments welcome) I've decided to do this inside the ZODB rather than rely on a relation database. This is largely because this data will - not be high-write - I want to do processing on all this of this data on multiple servers - and I am presuming that at some point in the not too distant future zope will let me replicate this data very easily to make it even more highly available. I tried using ZClasses but it seems to run slow and take up space. Instead I'm using Catalog (without ZCatalog) to contain the data. I'm presuming this will be quite efficient (comments welcome). Now to my question, How do Catalog plugable brains work? I've looked but can't see what the brain class has to look like to work. My first attempts don't seem to work. The classes are created but don't contain the data. Is the record data passed into the constructor? Also in my searches I came across lots of references to something called ZTables. This seems to be a Catalog with a UI that is about lots of tabular information (rather than a ZCatalog which is specialized to replicating and indexing existing objects). Is this dead? If not where is it? If so, why? It seems like a really good idea to me. It seems to be there are times when objects (esp ZClasses) are too heavy? Anyone with comments about how ZPatterns fits into all of this would also be welcome.
