Oh no! It has a different url. A leading slash! > "/MyFolder/myobject" > 11. Click on the link. It's broken! Hi Jason - these steps are equivalent to what is currently done on Zope.org (which is running on a checkout equivalent to 2.1.2), and this does not seem to be a problem there. While I won't totally rule out the possibility of something in Zope, the fact that we don't see this behavior seems to suggest that there might be something going awry in your particular ZClasses. In particular, I'd look for some difference in the way that it registers itself with the catalog at the time that it is created versus when it is "found" by the catalog. The difference could be a difference in either behavior, state or environment (i.e. is the acquisition context, etc. the same in both cases when the "absolute_url" method gets called to generate the url for the catalog? Is there any custom code around this logic?). The object constructor is a good place to start looking for this sort of thing - try to trace through the activity in the constructor versus what happens when the existing object is "found" by the catalog. If possible, try to see what the value of the url given to the catalog is what you expected it to be... > What this means is that if you have a lot of items in you > Catalog don't > ever ever ever use the "Find" machinery until Digital fixes this(It > worked in 2.0.0 Final).

I have not heard any other reports of a problem like this, so until we can verify that it is a Zope problem I think that this is a little strong. If other Zopistas can reproduce this I would certainly like to hear about it though. Brian Lloyd brian(a)digicool.com Product Manager 540.371.6909 Digital Creations http://www.digicool.com

Image Property?
by Markus Strickler 15 Jan '00

15 Jan '00

Hi! I have a ZClass and want to add a property that references an image object. I tried to add a string property that contains the ID of the image but I couldn't come up with a way to reference the image in my view method. All the images are in the folder /images/ The image IDs have to contain suffixes (.jpg, .gif, etc). I'm pretty sure this can be done but just can't find a way how to. Can anyone help? Markus

Refer to sequence-index within SQLmethod?
by Jerry.Spicklemire＠IFLYATA.COM 14 Jan '00

14 Jan '00

Hi again, Perhaps if I get in the habit of adding more detail in the first message, a higher number of Zenful types will feel they have enough information to hazard a guess. Better late than never, so here's a sample of the code in the SQL Query Template Edit Box : update user_login_table set unique_row_id = <dtml-sqlvar "_.string.zfill(_.str(_.int('sequence-index')),9)" type=nb> and, here are even more ways to try adding a "sequence-item" argument into the ZSQLmethod Edit Window that don't work : _.getitem(sequence-index) , "_.getitem(sequence-index)" , expr=_.getitem(sequence-index) , expr="_.getitem(sequence-index)" , and, "expr=_.getitem(sequence-index) BTW, the question is bound to come up, as in, "Why in the name of Zope do you need to do this?" Wouldn't the world would be a lovely place if every table that any Desktop Database user had ever misconceived included a Record ID? Alas no. The shameful truth is, all I'm really trying to do is stuff a string that's predictably exclusive into each row, so that I can comfortably fall back into my bad old habits from dBase days, and easily retrieve single records for processing . . . Thanks for any clues! Jerry S.

Accessing Folder Objects - Newbie Question
by James W. Howe 14 Jan '00

14 Jan '00

I have a situation where I want to ask a Folder (actually a ZClass) for a subset of the objects it manages. I want to do this from a DTMLMethod which exists in another folder. For example, suppose I have the following: FolderA NewsArticle1 NewsArticle2 FeatureArticle1 FeatureArticle2 NewsPage (a Folder) index.html (a DTMLMethod) FeaturePage (aFolder) index.html (a DTMLMethod) I would like to do something similar to the following in the NewsPage index.html method: <dtml-in allNewsArticles> <dtml-var Title> <dtml-var Teaser> </dtml-in> To make this work I would use a URL similar to this: http://foobar.com/Root/FolderA/NewsPage FolderA would implement the allNewsArticles method which would answer the collection of all contents in FolderA which are a "news article" (probably based on the meta-type of the object). My question is this, what would the code have to look like in allNewsArticles to make this work? Thanks. James W.

Image sizing
by coder＠kanga.nu 14 Jan '00

14 Jan '00

Given an image object (such as the perrenial single pixel invisible GIF oft used in tables), is there a more direct way to provide custom height and width tags for the image object than: <img src="<dtml-var invisible_img>" width=20 height=1> The normal: <dtml-var invisible_img> of course just uses the "correct" sizes... -- J C Lawrence Internet: claw(a)kanga.nu ----------(*) Internet: coder(a)kanga.nu ...Honorary Member of Clan McFud -- Teamer's Avenging Monolith...

Epoch time use
by Jerry.Spicklemire＠IFLYATA.COM 14 Jan '00

At last, something I know the asnwer to! The DTML Language Reference http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.html has an Appendix A, http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.19.html at the end. Even though there's no sample code anywhere on the page to show you how they work, there are lot's of cool formats here and it goes something like this : <dtml-call "REQUEST.set('this_time', _.DateTime fmt=AMPM)"> using the first on in the list as an example. I had to search back throuh old Mail List aArchive to find this. Good Luck! Jerry S.
