zopeNewbie Article on Acquisition
by Jeffrey N. Shelton 26 Nov '99

26 Nov '99

After a week's worth of evenings spent pecking away at the keyboard, I have posted an article on acquisition to the zopeNewbie site (http://weblogs.userland.com/zopeNewbies/) You can find the article, "Transition to Acquisition" at: http://weblogs.userland.com/zopeNewbies/breadcrumbs/acquisition/ I am interested in finding out whether this article helps those new to Zope better understand the concept of acquisition. I also want to know if my descriptions and explanations are technically correct. (After all, I am a zopeNewbie myself!) If you don't have the patience to slog through the whole thing, the stuff related directly to acquisition is at: http://weblogs.userland.com/zopeNewbies/breadcrumbs/acquisition/Behavior Thanks!

How do I convert an id to a string?
by Farzad Farid 26 Nov '99

26 Nov '99

This may be a simple problem but I tried all I could yesterday, I browsed the docs quickly and could not find the answer: I want to use the id of a object as a string in an expression and I can't find how to convert/extract the string representation of the id. I want to write some code like this: <dtml-comment>Do not show backup files</dtml-comment> <dtml-in "objectValues(['DTML Document'])"> <dtml-if "_.string.rfind(id, '~') != -1"> ^^^^^^^^^^^^^^^^^^^^^^^ <LI><A HREF="<dtml-var "absolute_url()">"><dtml-var title_or_id></A> </dtml-if> </dtml-in> What should I put in this expression in the place of 'id'?

RE: [Help] creating a new Image instance via external method
by Cayce Ullman 26 Nov '99

26 Nov '99

<The problem is that when I try to add the new Image < folder.manage_addImage(img.id, img.data, '') <I get a seek error as if there is something wrong with I have been doing something very similar to this, (I was uploading images that I got from urllib calls). And the key is to make the data a string, otherwise it assumes that data is a file handle. So try this : folder.manage_addImage(img.id, str(img.data),'') I think that will work. Also, you may run into some issues with that manage_upload's ability to guess the content type. If so, I would store, the original img's content-type and manually set the content type of your new image after it is created. Cayce __________________________________________________ Do You Yahoo!?

aborting DTML parsing
by Jan Stohner 26 Nov '99

26 Nov '99

Hello, i know that i can use <dtml-return> to return data from a DTML method. For example, when standard_html_header is called from a DTML document and i use <dtml-return> in standard_html_header, i'm back in the document with the result from the return tag. I am searching for a method to stop rendering at all, no matter how deep method calls are nested (a "return" would now stop rendering of the complete document). I searched the Mailing List archive but was only able to find a similar question (from Anthony Baxter, April 21), but not an answer. Is there a quick solution? I had the idea to implement a <dtml-quit> tag which is similar to <dtml-return> but raises a different exception, but i wasn't able to find the right place in the sources to catch this exception. Thanks for any help. Jan -- Dipl.-Inform.

Zopistas, Sorry for posting this to the list, but I couldn't find any contact info on the zGold pages. I've been trying to register there for almost a week now, and all I get is a "Zope Error Zope has encountered an error while publishing this resource. Error Type: Database Error Error Value: sqlAddQuery is not connected to a database" Does anybody know when it will be fixed? It would be interesting to have a peek inside. Regards, Alexander Limi. PS: For those who don't know what zGold is, it's located at http://d031.ml.uwcm.ac.uk/z/zGold/

Getting at form variables
by Shalabh Chaturvedi 26 Nov '99

26 Nov '99

I wanted that a url of the form 'http://url?a=b+c&d=e' produce a page like: [----desired-webpage---- You submitted: a = b c d = e ---------------------------] I have finally found the following way to do it:- [----dtml-snip------------ You submitted: <dtml-in "REQUEST.form.keys()"> <dtml-var sequence-item> = <dtml-var "REQUEST.form[_['sequence-item']]"> <br> </dtml-in> ---------------------------] Is there a neater/better way? More generally, given a dictionary called map and a string called key... <dtml-var map> prints `{a: 'b c', d: 'e' }` <dtml-var key> prints `a` ...is there a way to get at map[key] through DTML ? (`b c` in the above example) <dtml-var map[<dtml-var key>]> doesn't work. Thanks, Shalabh
