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

Cookies vs. browsers and other issues
by Sreeram Ramachandran 26 Feb '01

26 Feb '01

Hi, I am using LoginManager with Basic Cookie Authentication (using Zope 2.3.1b1). When I successfully login, I expect the browser to receive a cookie, right? Now, the problem is this: Netscape 4.76 on Linux and Links 0.82 on Linux don't pick up the cookie. Whereas, Lynx 2.8.3 on Linux and IE 5.something on Windows 2000 do pick it up. Has anyone experienced this? On similar/other browsers/platforms? Do you know why this is happening? I don't suspect there is any browser-specific code in LoginManager or HTTPResponse.py, so the problem can't be with Zope (maybe I'm wrong). Also, I can see the cookie quite clearly when I do a raw telnet to port 80 and submit my login form. I checked the format of the cookie received (using the telnet) and everything seems fine, like so: Set-Cookie: cookie_name="cookie_value"; Domain=my.domain; Path=/ (Changing the capitalization of Domain or Path has no effect). Meanwhile, here are some other observations: 1. I got burnt because of the implicit assumptions about how to render code found within a <dtml-raise> block. Zope assumes that anything that doesn't begin with a "<html>" or "<!doctype" is a fragment and so wraps its error message headers around it. My HTML used to start with "<?xml?>", so for a long time, I couldn't understand why my login-form wasn't working. 2. I am new to Zope, so maybe I don't quite appreciate how this works, but I was worried to read in the Zope Book that acquisition works based on the URL and not just the folder hierarchy. I.e., given a directory structure like this: ../ ..|-> gnu/ ..|...|-> rms ..|-> osi/ ......|-> esr Zope is quite happy with a URL like: /gnu/osi/esr/rms. Doesn't this have serious implications for security (i.e., one can call arbitrary dtml methods on arbitrary objects)? For example, if you do a "<dtml-var some_method>" carelessly (e.g.: implicitly assuming that some_method will only come from the same folder or one higher up towards the root), then you could be fried if someone puts an incompatible/malicious some_method elsewhere in the document tree, and then uses it in the URL? And oh, Zope is awesome! Thanks to each and everyone of you (for coding, submitting bugs, documenting, writing great extensions/products, helping newbies (like me!) or even just plain hanging around here on the mailing lists)!!! Thanks! Sreeram. -- ---------------------------------- Observation is the essence of art. ----------------------------------

List-admin problems
by Sreeram Ramachandran 26 Feb '01

26 Feb '01

Hi, Could the concerned people do something about these: 1. I got bumped off the zope(a)zope.org list for no apparent reason. I was subscribed on a "digest-only" basis, and suddenly I stopped receiving them. Anyhow, I resubscribed. Maybe the majordomo software got hosed? 2. The list archive at http://lists.zope.org/pipermail/zope/2001-February/ has got incorrect "hrefs" for all messages after 125791.html (about half- way down the page, as of this writing). My apologies for the bad formatting in my previous (and first) post here on the mailing lists. Cheers! Sreeram. PS: What is the correct email address to which such list-admin problems should be sent? -- ---------------------------------- Observation is the essence of art. ----------------------------------

Frustrated with ALL zcommerce solutions!
by James Sintz 26 Feb '01

26 Feb '01

After 2 months of struggling with Etailer, EMarket, and ZCommerce I give up! I busted my butt trying to get Etailer up and running only to be told by Adroit that they are no longer supporting Etailer in favor of a commercial app coming out in June (too far away for me). This, after asking a few tough questions about Wampum and offering to pay for help. EMarket is a whole other monster I have fought with for way too long as well. Steve has done a great job and has been very helpful, but still, trying to create even the simplest of stores has eluded me. The whole EMarket experience is like trying to put a puzzle together where someone has mixed pieces from an old puzzle in with the new puzzle and the reference photo is missing. ZCommerce, as simple as it seems, doesn't make any since either. Without the demo store I am clueless where to even start. If I install the demo store and then attempt to view the index_html page my Zope2.2.5 on Linux goes to 95% cpu and locks-up (yes I have a sessionstorage table in my gadfly database). Unfortunately, I'm not a programmer and the site I want the store for is a volunteer effort I work on in my spare time. This post is not meant to start the "if you want a canned app. then pay for a canned app." argument. I'm fully aware that every one of these products is worked on as time allows and are all being offered to help further Zope and eCommerce development. I don't expect anything, but I sure do HOPE :-) If anyone has created a simple store/shopping card that allows for secure processing of orders (and maybe a Wampum hook) and possible product images and would be willing to share the code, I would be willing to try and rustle up some cash (not sure how much). Thanks!!!! Jamey

empty lines property value
by zope＠concision.com 26 Feb '01

26 Feb '01

I just noticed that a property of type "lines", when created via the management interface (if not by other means as well) has as its initial value ['']. I would have expected an empty "lines" property to have the value []. Does anyone know the rationale behind this? Or should it be considered a bug? I see this behavior in both of the versions of Zope that we run locally -- 2.2.4 and 2.3.1b1.
