Namespace questions
by John R. Daily 26 Feb '01

26 Feb '01

I suspect I'm merely being dense, but I'm struggling to understand how Python scripts and DTML documents deal with the Zope namespace. As an example, assume that I've defined a /lib/foo/bar Python script, and in /tests/foo/lib/test1 I define a Python script that tests the functionality in /lib/foo/bar. container.lib.foo.bar works from test1 in other paths, but once 'lib' pops up in the local environment, things seem to break down. I've tried getPhysicalRoot(), but that doesn't seem to be defined in container or context. Can someone point me to a document explaining how to resolve these problems? Ideally, I'd like to also find out any best practices on organizing the Zope namespace. Thanks in advance. -- -- John R.

ZSQL Methods: surprising behavior, subtle bug
by Shai Berger 26 Feb '01

26 Feb '01

Hi, We just found a very subtle bug in our own application, which was caused by what I think is a surprising behavior of ZSQL methods. Actually, it's a feature of the query results. What we see is that they acquire the environment in which they were created. Essentially, our code did this <dtml-in query0> <dtml-let result1=query1 result2=query2> <dtml-with result1[0]> <dtml-with result2[0]> <dtml-var returned-by-both-query0-and-query1-but-not-query2> </dtml-with> </dtml-with> </dtml-let> </dtml-in> (Of course, the real setting is more complex, e.g. the dtml-withs are in a separate dtml-method, called within the let) To our surprise, the dtml-var picks the value of the variable as returned from query0. This is, I think, because this value is acquired by result2 where it is defined. I've checked this by accessing the variable as an attribute of the query-result row. Thought you'd all like to know, Shai.

Get browser information from HTTP_USER_AGENT..

Hello! I would like to get the information about user's browser but when I add these following tags in my dtml header, the result from the third condition is always true. (I checked with netscape and konqueror and the results were the same, Your browser is neither IE nor Netscape. ) Thank you so much in advance for any suggestion. <dtml-if "_.string.find(_['HTTP_USER_AGENT'], 'MSIE') <> -1"> <link href="<dtml-var "msie_css.absolute_url()">" rel="stylesheet" type="text/css"> Your browser is IE. <dtml-elif "_.string.find(_['HTTP_USER_AGENT'], 'NETSCAPE') <> -1"> <link href="<dtml-var "netscape_css.absolute_url()">" rel="stylesheet" type="text/css"> Your browser is Netscape. <dtml-else> <link href="<dtml-var "lw_global_css.absolute_url()">" rel="stylesheet" type="text/css"> Your browser is neither IE nor netscape. </dtml-if>

Question arisinfg from Beehive ZClass Tut
by Wayne Izatt 26 Feb '01

26 Feb '01

Hello. This is a question for someone familiar with the Beehive ZClass tutorial. Everything is quite reasonable. However, in the add_instance_html DTML Method, there is a dtml-call to Bookclass_add(_.None, _, NoRedir=1). I understand that "_" is the default namespace, but I don't get the "_.None" parameter. Any help woulf be much appreciated. _______________________________________________________ Do You Yahoo!? Get your free @yahoo.ca address at http://mail.yahoo.ca

Product and accessing DTMLDocument properties
by Andrew Williams 26 Feb '01

26 Feb '01

I have a product which I'm trying to develop and I would like to access the properties of a DTML Document and in the future other objects such as Folders. I have been able to get the default properties (ID) by looping through the tuples returned in obj.propertyItems() or by looping through the list returned by obj.propertyIds or even by accessing obj._properties The above methods work well for the default properties of an Object. However, these methods do not return added properties I have made to the DTML Document through the Zope management interface. What methods do I need to use in order to get a list of *all* properties on a DTML Document/object? I have been using DocFinder to display all of the methods available for a DTML Document, but haven't found what I need. (BTW, _excellent product!!). If this is already covered in a HowTo or somewhere else, please let me know and I will check it out. Thanks in advance for any help!

How to avoid repeated records from an OR search in ZCatalog?
by Ausum 26 Feb '01

26 Feb '01

As suggested by Caseman, it's possible in Zope 2.3 to do OR searches across different indexes using Zcatalog. Like this: <dtml-in expr="catalog(title=query) + catalog(summary=query)+ catalog(body=query) + catalog(notes=query)"> ........... </dtml-in> The problem is that if the queried word is found at more than one index, then its correspondant record will appear repeated as many times as the number of indexes for the same document. Has anybody dealed with this before? Is there a workaround (not using PrincipiaSearchSource)? Thanks in advance, Ausum

View a DTML Doc subclassed Z Class?
by Lars Heber 26 Feb '01

26 Feb '01

Hi there, it's me again. Thanks for all your hints with the date converting thing. Today I have another question: I have I ZClassed subclassed by DTMLDocument. My target is to initialize a number of DTML documents with some properties. No problem so far. But how on earth do I simply VIEW this document??? It's simple, plain HTML / DTML. Why isn't there a standard method activated on the Views tab in the ZClass? I tried to write such a method myself - without success. Let's say, the final instance's name is myDoc, then the following as class method works: <dtml-var myDoc> Of course, I would also give out the properties! But I don't know how the instance's name will be, when I write the class method! I tried things like: <dtml-var "_['id']()"> Because this is obviously what I want to do: Just call the DTML doc. I also tried <dtml-call "_.getitem('id')()"> and similar things - didn't work. I think I am completely blind, I'm doing something totally wrong, but I don't know what. Could you please help me another time? Thousand Thanks Lars
