preventing acquisition
by Robin Becker 01 Nov '00

01 Nov '00

I have some folderish Zclasses which have index_html methods to implement a UI. I would like to inhibit acquisition of these. So if I have a path /A/B/C I would like to inhibit the behaviour that allows me to view /A/B/C/A and /A/B/C/A/B/C etc. to inhibit the first I can put something like <dtml-if "PARENTS[0].id not in PARENTS[1].objectIds()"> <dtml-raise NotFound> <h2>You're not supposed to be looking at <dtml-var "absolute_url()"> </h2> </dtml-raise> </dtml-if> in my index_html, but this doesn't work for the second case. Is there a generic way to do this? -- Robin Becker

Sorry, resolved

Just had to add an "index_html" to the ZClass, now it works. So it looks as if "looking for index_html" starts at the ZClass itself. thanks for listening anyway ;-) Danny -----Ursprüngliche Nachricht----- Von: zope-admin(a)zope.org [mailto:zope-admin@zope.org]Im Auftrag von Danny William Adair Gesendet: Dienstag, 31. Oktober 2000 19:38 An: zope(a)zope.org Betreff: [Zope] Change rendering of a folder Hi, I would like to subclass the folder class and change the way it gets rendered. How would no how will I do that? Usually, a folder object looks if it contains a index_html and calls(renders) it if so. I would like to change this behavior and call a method of my own when the object gets rendered. I remember the rstx_document example, where you subclass from the original and add "Renderable" to the base classes(I think it was important which first), then provide a "render" method in your new ZClass and that's it. This didn't work for "Folder". btw, would I subclass from "OFS: Folder" or from "ObjectManager"? tia, Danny _______________________________________________ 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 )

GoLive

Does anybody know, if there is a way to automate GoLive for Zope? I have a customer who is Mac user. It seems to me, that GoLive is configurable to do almost every webdesign task without any knowledge. So I think there should be some upload automatism. Is there? And are there known problems with Zope? _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

RE: [Zope] My Items will not show themself in manage_main (object Items)
by Max Møller Rasmussen 01 Nov '00

From: Ender [mailto:kthangavelu@earthlink.net] First os all. Thank you for the patience. I know it is boring to "Solve other peoples problems for them", but I am really trying hard myself, reading the source of Zope and other products. It's just such a steap learning curve because it is underdocumented. (I have 6+ years of experience in web scripting and 12+ in programming + database overall, so usually i catch on fast.) >> I was under the impression that when I inherit ObjectManager that my object >> would be a complete ObjectManager. But do I have to overwrite some methods >> with my own? >No you don't but generally an objectmanager would wants to add some >custom logic, like a Folder which is a specialized objectmanager. I don't want that in this product. It should just be a plain folder, where anything can be put. Well at least Foders, images and dtml methods. >ok, i'm not certain that i understand your problem. you original problem >was getting dtml methods to show up in the manage views. in your product >your it appears that your methods aren't really dtml methods that are >contained within the objectmanager but rather class methods of the >discussion class. to have them show up in the manage_views you need to >change them to be methods that are added to a discussion object. In my mxm_diskuss class I have a list containing messages: self.testComments = [.....] (will be renamed to "comments" when it's done.) These comments are not meant to be seen in the folder view, they should only be visible when called through dtml methods. like this method to make a list of all messages: index_html: <dtml-var standard_html_header> <dtml-in testComments> <b><a href="view?id=<dtml-var id>"><dtml-var title></a></b> By: <dtml-var author> <i><dtml-var date></i><br> </dtml-in> <dtml-var standard_html_footer> What I find "brilliant" about the idea is that when a customer wants a discussion group I only have to change 3 standard dtml files to give it a new functional interface. And I can build a library of look and feels. And there is no recursion in it so it will behave like a list, and be easily codeable from dtml. The last discussion product ever needed :-) It will be ZPL (when it's done.) >here some code that illustrates how. ># add a folder for view >self.manage_addFolder('views') ># get a file handle >fh = open(join(Views_Dir, 'DiscussionIndex.dtml')) ># add a DTML method with contents of the file. >self.views.manage_addDTMLMethod(id='news_center_index_html', file=fh) >a method created this way will show up in the manage_view of the object. My problem is not adding object programatically, but doing it in the management interface. When I add them I can press "add & edit" and I can paste the dtml source, and the method works. But they don't show up on the list when viewing the folder. Well I guess that if I dont have to do anything special to add objects to an objectmanager, then I must have a permission problem when viewing them. I guess I will look more into that. Currently I am lookin for a permission that prevents seing the ObjectItems in an objectmanager, but so far without any luck. grr... documentation. Kind regards Max M

It is very easy to make them persistent. When I remember correctly, it was only necessary to pass "commit" to Gadfly. Dieter
