I still don't think I've > got my head around the _['whatever'] syntax. You like that you can use <dtml-var name> both for properties, external methods and DTML objects? If you do, then you probably like that "_['name']" does the same. "_[...]" evaluates '...' (which should yield a string), looks that up in the namespace (giving an object), determines what type it is (external method, DTML object, something callable, something else) and does what usually is right for such an object. This means, it either calls the method/object with appropriate parameters or returns the object itself (if not callable). If you do not like this, you can use "_.getitem(...)". This returns the object itself, without magical type specific handling. I think, the "multiple personality disorder" does not refer to this "_[...]" intelligence but to the fact, that "id" usually is a (parameterless) method but sometimes is an attribute. The "_[...]" and "<dtml-var name>" magic usually hides this disorder, but without the magic, you may get hit by this design flaw. Dieter

Python requires names to start with a letter. You name "7Dlogoicon_gif" starts with a digit. That is the problem. You can use "_.getitem('7Dlogoicon_gif').tag(border = 0)">, instead Dieter

Hello I asked this in longer form before, but it fell by the way I think.. How to add a property to a containing folder. Looking for DTML or External Method way to do this. We need a Method to to add a new folder property assigning an 'Id' = <somename> adn 'type' = 'tokens'.

Organizing huge content
by brocken22＠gmx.de 14 Sep '00

Hallo, my question is about organizing scripting when you have to deal with huge amounts of content. I.e. you have a custom that wants to establish a website .This website should have in the future about 2000 pages but you on your own are building only some pages and a lot of templates that his coworkers can use to build the rest(new pages oder updating old ones). Now the point: I plan to make a ZClass and the new sites are instances of this class. The look (and feel)is individualized by iterating over the properties? Or is it better (in terms of speed)to create a couple of ZClasses and reducing the amount of properties? Many thanks. -- Sent through GMX FreeMail - http://www.gmx.net

Permissions logic and redirecting failed logins cleanly
by Jason Cunliffe 14 Sep '00

14 Sep '00

Hello We have folder on our site with a list of links to restricted pages and downloadable binary objects. 1. 'Anonymous' can view the index_html of the top level folder for this part of the site. I did this by selecting 'Security' tab of my Zope folder, and then deselected the 'Aquire permissions' boxes for 'View' and 'Access Content Information' I then added 'View' permsission manually for role 'Anonymous' I did the same for 'index_html' but also manually added 'Access Contents Information' permission for role 'Anonymous' Everything works fine. Anyone can read about it an see the links to objects below this point, but clicking on them or typing in direct URL will open a {user, password}login dialogue box. Good. Now if people do not enter a valid login, after a few tries it bounces as you would expect to a Zope error screen. This is nice when you expect it, but inexperienced users are confused or think the site is 'broken' when in fact it is working. What we need is to redirect 'Anonymous' users [or indeed anyone] to another page if their login fails. For example: ....................... "The item your tried to access is restricted and requires member login blahblahblah. Contact mailto:webmaster@thissite.com with your request click [HERE] to return ........................ How to detect and redirect to a page like this? Thanks for any suggestions - Jason ________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director

Hi, I would like to incorporate a load of static HTML pages into my Zope website. My question: what is the best way to do this? Is there a product to this.? I don't really want to have to use Apache. Regards, Nick.

FTP Server bug or feature
by J�lio Dinis Silva 14 Sep '00

14 Sep '00

Hi all, just to check: with zope 220 when I do any changes to a normal user in a normal acl_users folder this user can no more access the zope module via ftp, i.e, login ok but a simple dir command return a unauthorized error . Isn't suppose to the FTP server view this changes cause its accessing the acl_users in memory? I only solve this restarting the ftp server. Is suppose to be like this, restart the ftp server to reflect user permissions changes?

Oedipus / Zope / python / product / XML ++
by Jørgen Skogstad 14 Sep '00

14 Sep '00

Hi there .. I've been looking into something this weekend. I need somehting that can handle my link database etc. and list them through Zope on a regular basis. I was looking at Oedipus which can create "semi-xml" DMOZ like directories which would suffice for v0.1b of my product. I was thinking of using Oedipus and store them in the database there and generate a new xml-like-structure every day through some cron script. .. what I was hoping for is to use the LocalFS product for Zope and some kind of python "product" (which I need to make to fit into Zope) which can parse this .. sort of like the *.cgi script which followed with the Oedipus installation. By doing this; I can generate DMOZ/Link databases that show information about the site; when it was checked last, updated etc. etc. My questions are as follows; * How do I generate a package of some pythong scripts? * Are there any better ways of parsing and putting this xml-like file under "Zope control" .. * Are there any XML products for Zope that can get a file from an url .. and parse this with some python scripts to generate a yahoo type listing? Would apriciate any input! -- Med vennlig hilsen, Jørgen Skogstad /\ System Specialist \\ \ \ \\ / Sun Microsystems AS / \/ / / Gjerdrums vei 12 / / \//\ N-0486 Oslo, NORWAY \//\ / / / / /\ / Phone: + 47 22 02 39 00 / \\ \ Cellular: + 47 92 41 30 23 \ \\ Fax: + 47 22 02 39 99 \/ EMail: jorgen.skogstad(a)Norway.Sun.Com Web: www.sun.no BTW; Opinions formed by myself in informal mailings are mine and not of my employer.

How to give content maangers ability to update a Zope site ?
by Richard Moon 14 Sep '00

14 Sep '00

How would you give a content manager the ability to update a live Zope site ? What I have is an in-house development site with various folders and each folder has a manager. I thought I would be able to let them use FTP on port 8021 to unload objects from the development site and update a live site on the 'net. However it seems that FTP can only unload DTML documents and methods and can't unload SQL Methods, ACL User Folders or Database Connection Methods. Plan B was to use the export facility but they would then need to have telnet access to the Zope import directory in order to put the .zexp file there, which seems a huge security gap to me. Am I missing something obvious, how would you do it ? Thanks Richard Moon richard(a)dcs.co.uk
