Creating and pasting to a ZClass within a single transaction does not work
by Kevin Dangoor 26 Aug '99

26 Aug '99

Hi, Last week, there was an exchange going on because I was having trouble copying and pasting in DTML (or Python) from a Folder to a ZClass instance. The thread started with http://www.zope.org/pipermail/zope-dev/1999-August/001248.html It looks like the problem is that I was creating the ZClass instance and doing the copy/paste operation all at once. If I use one DTML method to create the new objects, and then a second method to do the copy/paste, everything works just fine. Should there be a problem pasting objects to a new object within the same transaction? Kevin

PROPOSAL: html_quote implicit in entity-reference var tag syntax
by Jim Fulton 25 Aug '99

25 Aug '99

Zope 2.0 allows you to use an entity-reference syntax for the var tag. For example, you can do: <a href="&dtml-URL1;"> rather than: <a href="<dtml-var URL1>"> Unfortunately, you always need html_quote in a situation like this. I propose that: &dtml-name; should be equivalent to: <dtml-var name html_quote> (Or, of course:  ) Without this change, I think the entity-reference syntax doesn't really solve the problem it was designed to solve. Can anyone think of a case where you need the entity-reference syntax and wouldn't want html_quote? I feel that this change needs to be made now, before Zope 2.0 final, since it is not backward compatible. For example, if someone has a document like: &dtml-standard_html_header; .... &dtml-standard_html_footer; Making html_quote explicit will break their document. Comments?

Re: [Zope-dev] Creating and pasting to a ZClass within a single transaction does not work

Replying to myself... Oddly enough, I'm actually getting two copies of the images (imagename and copy_of_imagename). If there are two images, then I will end up with 4 image objects in the destination object. Here's the python method that I'm using: def candp(fobj, tobj, REQUEST): "Copy and paste" ids = fobj.objectIds() if not ids: return cdata = fobj.manage_copyObjects(ids) tobj.manage_pasteObjects(cdata, REQUEST) Any idea why I would get *two* copies of everything from this?

It would be substantially more helpful if you were to provide more information regarding this, such as: * Server Platform information * Browser information And the EXACT situation that occurred Such global declarations are largely useless for debugging purposes.

Login/Authentication/Authorization tools wrt SquishDot
by Neal Holtz 25 Aug '99

25 Aug '99

See standard apologies below. I'm quite interested in using SquishDot as a base for web page support for university-level courses that I teach. I like the article-based discussion groups and the general slashdot-like presentation. I'm willing (at this stage) to do whatever Python and DTML programming is required for the special needs for course pages (there shouldn't be all that much). I also like the security model - I can define roles for Instructors, Teaching Assistants, Registered Students and Anonymous Guests, etc., with different rights for each. A couple of things I need though: 1. A way to identify in DTML the rights of the current user, so pages can be adapted. I would like to get the loginId for the user, but more important, I think, would be just a way to test for various roles. EG: "is the current user a registered student?", etc. A Quick reading of Publish.py (in Zope 1.10.3) seems to show all the authorization logic deeply bound into method 'publish', and it would be nice to have that brought out into a separate method. 2. A way to import a few hundred userids, passwords, and roles, from our own registration databases. Or would it be better to let the webserver authenticate people? - I was going to let Zope do it. 3. A way to have a 'login' link that allows a user to change their identities at any time (more useful for me during testing, but I would like anyone to be able to view pages anonymously at any time, but only have to login when they wish to post an unmoderated response to an article. I haven't seen any obvious way to do any of this. Did I miss something? Is anyone else working on something similar? If this is already documented somewhere (if only in Python code), pointers to that would be just fine. Standard Apologies: I'm pretty new to Zope, and I haven't exhaustively searched the mail archives, so my apologies if its already been covered. Time is running out, the first day of classes approaches all too quickly ... I'm a competent programmer, and not afraid to get my hands dirty ... thanks neal -- Neal Holtz http://www.docuweb.ca/~nholtz Dept. of Civil and Environmental Engineering, Carleton University, Ottawa, Ontario, Canada K1S 5B6. nholtz(a)docuweb.ca

ZClasses as *methods*
by Martijn Faassen 25 Aug '99

25 Aug '99

Hi there, For a while now I've been trying to accomplish the following with ZClasses: I have a ZClass called 'Router'. This ZClass should call DTML Methods dependent on a variable in REQUEST. The simplest case of what I'd like is that Router goes into DTML Method 'Foo' if there's a request variable called 'hoi', and otherwise it goes into DTML Method 'Bar'. The tricky bit is that I want the Router object to behave the same as a DTML Method in the respect that it also should be a member function of the folder, not an object by itself. This way it can be acquired like DTML methods, and I can build a structure consisting of DTML methods and Routers, for instance to transform an XMLDocument into HTML. What the Routers would do is in this case is transform some parts of the XML tree differently dependent on a variable in REQUEST. For instance, I could have a request variable 'focus' set to an id in an XML Document (for instance 'e1'). Then, during the rendering of 'e1', the Router object sees 'Focus' is set to that value, and reacts by calling a different rendering method (that for instance colors text purple so that the element is displayed in purple in the resulting HTML). But, I can't seem to be able to write a ZClass that does this. I try inheriting from a Python base class and overriding __call__, but the resulting objects don't behave like DTML Methods -- 'self' becomes the instance of that object, instead of the XML Document I'm working on, like it is with DTML Methods. So, what makes DTML Methods special? Am I going about the right route at all? Any suggestions at all would be very welcome. Regards, Martijn

big-site on multiple domains
by Andy Pahne 25 Aug '99

25 Aug '99

hi there, at the moment i am planning a site for a company in seven (!) languages. in general i want to admin the site central from one point, but there will be others to contribute the contents in the different languages. i think that zope is a good solution for this purpose. my problem is: the site will be housed on one server, lets say: apache.foo.bar but there are several virtual domains on this server, e.g: www.name.com www.anotherName.net www.yetAnotherName.de .... my question: can i use zope to take this site up? i know, it would be easier, if evrything would reside on one webserver, but in this special case it can not. andy pahne
