Help : changeOwnership
by Pascal Romon 06 Dec '02

06 Dec '02

Could someone help me understanding how to change ownership of an object ? I've looked through the lists and docs to no avail :-( [ Let me point out that I am a newbie ... ] Problem (obvious) : objects created by manager are owned by manager. I want to relinquish ownership to a given user. Solutions (not working) : I seen some scripts using changeOwnership BUT 1) some scripts use a __of__ method that my Zope does not accept (eg a cool chown script http://www.zope.org/Members/vernier/Debian/CMF_Creator ) 2) others are accepted by Zope, like -- stupid -- changeOwnership(username) but upon execution of /.../object/chown?username=blahblah I get after typing in the identity & password "You are not authorized to access this resource. Username and password are not correct. " (either as manager or as the user involved). What's going on ? Thanks Pascal

I can add and remove users in [acl_users]. But it is not possible to edit a user. I get the error message [error type: AttributeError, error value: domains] below. It does not make any difference if I fill in a domain or not. I am *very* happy if someone can help me.

Re: Bug or Feature (dtml-in)?
by Lars Heber 06 Dec '02

06 Dec '02

Ok, now I've got it. It was because not every folder had the property "index", which I used for sorting in the "in"-tag. Repaired that, now it works. Anyway, this behaviour is confusing and in my mind buggy... Should this become an issue for the collector? -- Lars Heber T-Systems GEI GmbH Hausanschrift: Clausstrasse 3, 09126 Chemnitz Postanschrift: Clausstrasse 3, 09126 Chemnitz Telefon : (+49 371) 5359-271 Fax : (+49 371) 5359-133 E-Mail : Lars.Heber(a)t-systems.com Internet: http://www.t-systems.de

ObjectManager API and Zope3
by Thomas Guettler 06 Dec '02

06 Dec '02

Hi! Does someone know why ObjectManager has its own "API"? I think it would be better if the API would be like python's dictionary: has_key, values, items ... Somehow I don't like objectValues, objectItems ... Will this be changed for Zope3? thomas -- Thomas Guettler <guettli(a)thomas-guettler.de> http://www.thomas-guettler.de

POSting from a python script.
by Alec Munro 06 Dec '02

06 Dec '02

Hi all, Is it possible to post data to a site from a python script? Basically I want have the user fill out a form, have that form's action be a python script, and then have the python script submit a post request to another site, and then return a page on my site to the user. I'm sure if this can be done it's fairly trivial, but I cannot think of how to do it. Also, I want to be able to recieve the response to the posted data. Thanks, Alec Munro

ZopeTop, xul, etc.
by Philippe Jadin 06 Dec '02

06 Dec '02

Hi, It seems there is currently work done on the future UI for zope3. I have some questions / comments on this (I hope it's the right list...) - Isn't it strange to use html to create a modular user interface? As I see it, html is not an UI definition language. - is there currently active projects to build a fat client interface for zope using xul or other technology? If html is not the right tool for the job, and if xul is really as good as it seems : - zope should use an intermediate layer between the core logic / datastructures and the UI. This layer could be something like xul - xul is xml, and as such could be "converted" to xhtml. The conversion would reduce a lot the usability (you cannot do everything xul does with html), but at least there would be a single source of UI definition and multiple implementations (simple html, "flashy" dhtml, pure mozilla xul, etc...). - xul can be used directely in mozilla, providing a very powerfull client-side interface. I think it can be seen as a rapid interface developement tool. In short, zope core -> "html ui" is not too good zope core -> "something" -> html would be more modular. the "something" could be xul... or wathever, the point is "there must be something" :) What do you think? Philippe Jadin ps : is it possible to contact the people currently working at the infrae sprint (irc?)?
