"ease of maintenance". If I put the images in Zope, I get: revision control versions ease of updates from development to production sites (just copy the data.fs files) and a whole host of other advantages. As well, there's not the issue of having to keep a list of files in your head or whatever, so that Zope doesn't start referring to non-existant or renamed images. Anthony

Images are almost universally static content, especially with the current Unisys GIF licensing idiocy. As such there is very little reason to have Zope serve them directly, or to spend those resources. > I am going to be using Zope to serve a pretty tame website -- not > too much traffic, not too much updating -- but it saves me *lots* > of time writing repetitive HTML and fixing mistakes made during > updates. Agreed. However you can still use Zope, indrectly, to serve your static content (images) in any of several ways,m such as a root property or DTML method which contains http://domain:1234/image.png, and you tehn merely reference the variable or method in the normal manner. > Any content that changes over time isn't static. Agreed. However images normally don't fit into that category, or if they do (such as over site-redesigns), appropriate use of symlinks acts as a useful (and self-documenting) abstraction layer. -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--

Putting a Poll in a web page...
by Don Undeen 24 Jan '00

24 Jan '00

He there. I'm toying with the Poll product, which seems quite neat. I'm sure this problems comes from my inexperience with working with products, but maybe you can help my understanding with this one issue, and broader issues as well. I've created a poll, which works just fine when I go to it by itself, but I want to include it in another page. What tags do I write to put the poll (ID: pollitem1) in another web page? I've tried <dtml-with pollitem1><dtml-var index_html></dtml-with> , Which shows the poll, but I get a "resource not found" error when I run it, because it's trying to submit to /Users/Username/processVotes, instead of /Users/Username/pollitem1/processVotes. The submit line is created in pollitem1/index_html . Do I just need to edit that index_html file to add that to the path? Or is there another way of tagging that pollitem1 in my DTML-document, so that it works? I hope this question is not too vague, I'm still trying to master the semantics of this paradigm. Thank you, Don Undeen dundee(a)gator.net

AUTHENTICATED_USER Question
by schenck 24 Jan '00

24 Jan '00

An earlier note on this list referred to a Zope article by Jon Udell in Byte. In that article Jon included the following bit of code in a <dtml-calendar ...> example: <dtml-if "AUTHENTICATED_USER.has_role()=='Manager'"> When I try to execute this code using Zope 2.1.2 on Windows I get the following error: =============================================== Error Type: TypeError Error Value: not enough arguments; expected 2, got 1 Traceback (innermost last): File D:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 214, in publish_module File D:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 179, in publish File D:\Program Files\Zope\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File D:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 165, in publish File D:\Program Files\Zope\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: testCalendar) File D:\Program Files\Zope\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: testCalendar) File D:\Program Files\Zope\lib\python\OFS\DTMLMethod.py, line 145, in __call__ (Object: testCalendar) File D:\Program Files\Zope\lib\python\DocumentTemplate\DT_String.py, line 502, in __call__ (Object: testCalendar) File d:\Program Files\Zope\lib\python\Products\Calendar\CalendarTag.py, line 276, in render File d:\Program Files\Zope\lib\python\Products\Calendar\CalendarTag.py, line 312, in render_wm File d:\Program Files\Zope\lib\python\Products\Calendar\CalendarTag.py, line 353, in render_day_ File D:\Program Files\Zope\lib\python\DocumentTemplate\DT_Let.py, line 145, in render (Object: d="date.Date()" hasdate="hasProperty(d)" dprop="getProperty(d)") File D:\Program Files\Zope\lib\python\DocumentTemplate\DT_Util.py, line 335, in eval (Object: AUTHENTICATED_USER.has_role()=='Manager') (Info: AUTHENTICATED_USER) File <string>, line 0, in ?

help on addProperty
by Jerome ALET 24 Jan '00

24 Jan '00

Hi there, I'm having a newbie problem: I've created a form asking for some fields (id, title, link) and I want to create a folder with id=id and title=title but with a new property called link whose value is the value typed in the form for field named link. after having quickly read the list archives, I'm now able to create the folder, but whenever I try to create the property it's created in the folder's parent. here's what I do: ---------- <dtml-call "manage_addFolder(REQUEST['id'], REQUEST['title'], REQUEST=_.None)"> <dtml-with "REQUEST.id"> <dtml-call "manage_addProperty('link', REQUEST['link'], 'string')"> </dtml-with> ---------- the manage_addFolder works as expected, but the manage_addProperty creates the property in the newly created folder's parent. please could someone give me some help. another question: where can I find a complete reference on useable methods and their parameters ? thanks. Jerome

Hi all, will some Zope-friendly booth (i guess DC will not be present ...) be available at the fortcoming French Linux-Expo (http://www.linux-expo.com) on February 1-3 ? If there is some Zopistas here, we can have a beer somewhere.

Yes, I probably made this more confusing than it needed to be, since there is no specific reference to images anywhere in the article. However, if you look at the actual rendered calendar, you'll see an image there. In other words, the dtml code (see sample code in the article) discovered the image object, and rendered it, without knowing anything more about it than the fact that it was bound to a day, and that day fell within the scope of the calendar's date range. After you've created a Zope image object, named "image1", in the subdirectory named "subdir" you can render it explicitly like so: <image src="/subdir/image1"> -----Original Message----- From: Daniel G.

I have used the Image Product in the past the problem I am having is that when I create an Image Object in Zope the image needs to be on my local machine? My image(s) are on the server? Am I missing something?
