You have two options: 1) To get a list of roles - <dtml-var "AUTHENTICATED_USER.getRoles()"> 2) To check if they have a specific role - <dtml-var "AUTHENTICATED_USER.has_role('role_name')"> Hope this helps.

Well, i do agree that Zope seems to offer more features (from the case studies, and this mailing list i have read so far). I have played with PHP in my previous project, programming by using classes(object-oriented), though OOP support in PHP is not extensive yet. So far the codes are still maintainable, but a lot of things i have to "mix-and-match" myself if i want to include features like authentication/session tracking, templates, etc. That's why i'm looking at Zope for the possibility of a better solution. >What I *would* suggest focusing on is can Zope provide you with >the right amount of features and functionality and can you >scale it?

Well, i don't think my site will ever get that much hits:) Anyway, i check out Digicool website on this ZEO thing, and it seems that they charge abt $25,000 for this product alone(+consulting)? Not to belittle their effort, but that's a huge amount of money, considering that everything nowadays is "open-source":). Or did i interpret it wrongly?

RE: [Zope] Redirect Back
by Chris McDonough 07 Jul '00

07 Jul '00

You may either use Javascript's history method or use RESPONSE.REDIRECT(REQUEST['HTTP_REFERER']). The former is preferred as the latter isn't always accurate nor available. > -----Original Message----- > From: Aaron Williamson [mailto:aaronw@c.ict.om.org] > Sent: Friday, July 07, 2000 11:45 AM > To: zope(a)zope.org > Subject: [Zope] Redirect Back > > > Does anyone know if RESPONSE.redirect() can somehow be used > to send the > user "back," like they clicked the back button on the browser? > > Thanks, > > Aaron Williamson > Operation Mobilisation > aaronw(a)c.ict.om.org > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

DTML method to add a folder and put image inside
by John Verzani 07 Jul '00

07 Jul '00

Zope has me stumped. I want to make a _simple_ form and process to add a folder then insert into that folder some properties and an image. Here is what I am trying with my DTML method for processing the form request: <dtml-call "manage_addFolder(REQUEST['id'],REQUEST['title'])"> <dtml-with "REQUEST['id']"> <dtml-if image> <dtml-call "manage_addImage('image',image)"> </dtml-if> <dtml-call "manage_addProperty('example',example,'text')"> </dtml-with> <dtml-call "RESPONSE.redirect(URL1+'/manage_workspace')"> I thought by using the <dtml-with> and the folder id that the subsequent manaage_add* would add to the newly created folder. I know I'm on the right track for when I hardcode the folder name (replace REQUEST['id'] with a string) what I want to do works.

Redirect Back

Does anyone know if RESPONSE.redirect() can somehow be used to send the user "back," like they clicked the back button on the browser? Thanks, Aaron Williamson Operation Mobilisation aaronw(a)c.ict.om.org

Calculate difference between time input?
by Peter Arvidsson 07 Jul '00

07 Jul '00

How do I calculate the difference between two times I get from a from? Lets say time a = 09:45 and time b = 11:15 Then I want to calculate the difference. How do I calculate it? I'd also like to know how to get the answers in differen formats. For example caculating the input above I want to be able to get all of the following results: 1:30 (One hour and thirty minutes) 1,5 (One and a half hour) 90 (Ninety minutes) Help please :)

Problem with database packing (major data loss)
by Richard Taylor 07 Jul '00

07 Jul '00

We have discovered a rather nasty problem. On Zope 2.1.6 if you you pack the database with '0' in the days box and then pack it again with '1' in the days box bad things happen. In our case the first pack resulted in a Data.fs of 17MBytes (not bad from a started point of nearly 2GBytes) the second pack (which I assumed would do nothing) resulted in a Data.fs of 3MBytes. Great I thought, however it also broke most of my site. Some of the symptoms are: Accessing existing folders gives KeyError Many of my ZClasses are turned into DTML Methods (that is the icon next to them in the folder view is a DTML Method icon) All the instances of the broken classes are broken. Thankfully I kept backups before performing the packs. This is repeatable on both the servers I run. I am now nervous of packing but have no choice. Richard PS. I still think Zope is great! I am just learning slowing how to run it defensively

zsql question (cannot render query template)
by Oliver Frommel 07 Jul '00

07 Jul '00

Hi, I have a simple SQL method which just does a select on all rows, ie. "select * from users", which works. for security reasons I want to embed the sql statement in another dtml if- clause, like that: <dtml-if checkperm> select * from users </dtml-if> (checkperm is a DTML method which returns either 0 or 1) when I try to test the SQL method I get the following error: Error, exceptions.NameError: REQUEST SQL used: Could not render the query template! what am I doing wrong? thanks -Oliver
