How to assign a value to a dtml variable after it has been create d with the let dtml tag ?
by Bocquillon Philippe 08 Aug '01

08 Aug '01

Hello, In the piece of DTML code here after, I'm trying to compare each element of getAllPortalCategories() with each of getCategories(). I would like to have each element as a selected option in the generated HTML if this element is in both lists. Here the error I get is that Zope searches for a variable named 'false'. I would want Zope considers 'false' as a string value assigned to isSelected, not as a var to search. But my problem is more general: how can I modify the value of a dtml variable? <tr> <th align="LEFT" valign="TOP">Categories (current ones are selected)</th> </tr> <td align="LEFT" valign="TOP"> <select multiple name="categories:list" size=10> <dtml-in expr="getAllPortalCategories()"> <dtml-let aPortalCategory=sequence-item isSelected='false'> <dtml-in expr="getCategories()"> <dtml-if expr="aPortalCategory == _['sequence-item']"> _['isSelected']='true' </dtml-if> </dtml-in> <dtml-if expr="_[isSelected]=='true'"> <option selected> <dtml-var aPortalCategory> </option> <dtml-else> <option> <dtml-var aPortalCategory> </option> </dtml-if> </dtml-let> </dtml-in> </td> Thanks in advance, Philippe

Zope w/ MailMan.

hi, I'm having a bit of trouble with Zope and mailman. I end up with an error about translating the administrative cookie. I can logon to the Admin pages, but when I submit changes I keep getting prompted for the admin password. Probably a re-write rule. j. -- ...................... ..... Jason C. Leach ..

compile python on openbsd

Hello: I have read the install.txt in the zope.src for the current release. It says I must use libpthread for my python compile. Where do I find this file. Once I get the library, when I cimpile python; I assume I use the use-lib = path or something like that. I cant find any docs on the web that tell me how to find this library. I've seen references to libpthread.so . But not much in english. cj

It may just be me, but your question doesn't make sense. I think you want to: 1) Make a zclass that holds the data 2) Write an external method that parses the csv file and 3) use the same external method to add instances of the ZClass with the data from the csv file.

Shallow copies/links/references
by Mario Valente 08 Aug '01

08 Aug '01

Hi: OK everyone, I've managed to get object links to work. As discussed previously by others (re: object references) and asked by myself: I had the need to be able to refer to objects from different points of the folder hierarchy without duplicating those objects. Yes I know that can be done *programatically*. That is not the idea. The idea is to have a folder with differente widgets/components and to be able to copy and paste references to those widgets throughout the folder hierarchy. Of course that the usual copy/paste is not OK, since that *duplicates* the objects and as such further changes to the original object wont be reflected in the copies. With something like this + Ordered Folders you are able to have an index_html that just renders the objects within a folder and you can then drop objects/widgets into the folder to produce a page. What I did: - edited CopySupport.py - copied the manage_pasteObjects method to a manage_pasteMonikers method - commented the #ob=ob._getCopy(self) line (the duplicate object part) - added a "Paste Ref" button to the lib/python/OFS/dtml/main.dtml file that calls the pasteMonikers method """ <input class="form-element" type="submit" name="manage_pasteMonikers:method" value="Paste Ref." /> """ It works. It does what I want/need. When you change a reference, the original also changes. When you change the original, the references change. You can delete either the reference or the original and all is OK. Issues/TODO - find a way to distinguish references from the original (tried to change the meta_type at paste time but no luck). At least the meta_type/icon should change to provide a visual cue. - provide tool(s) to find impact of changing a reference. Provide a link from a reference object to the original. Provide a link from an object to its several references. Comments and experiences are welcome. C U! -- Mario Valente

ZCatalog searching
by brian.r.brinegar.1 08 Aug '01

08 Aug '01

I would like to something where I list off objects in a folder and specify which objects are currently cataloged in a specific ZCatalog. Is there a good way to say, "Is this object in the catalog?" something like ZCatalog.isObjectCataloged(object). --Brian Brinegar ECN Web Technician CEE Undergraduate Programmer MSEE 104 A 494-3106 http://www.geeksoft.net/

Re: [Zope] How to assign a value to a dtml variable after it has been created with the let dtml tag ?
by Shai Berger 08 Aug '01

08 Aug '01

Hi Philippe, General advice: Your code is getting too complicated for dtml. You will do much better by calculating your list of options in a Python Script. For your first problem: The only way to specify constants in dtml is as python expressions. So you would need <dtml-let isSelected="'false'"> (A python expression for a string). For what you really need: The only way you can change a variable in dtml-let is if you can do it with an expression. An assignment is a statement, so you can't use it in dtml. You need something along the lines of <dtml-let isSelected="[]"> (an empty list is false) <dtml-if ...> <dtml-call "isSelected.append(1)"> (a non-empty list is true) </dtml-if> ... But you can do everything with <select multiple name="categories:list" size=10> <dtml-let selectedcats="getCategories()"> <dtml-in expr="getAllPortalCategories()"> <dtml-let aPortalCategory=sequence-item> <dtml-if "aPortalCategory in selectedcats"> <option selected> <dtml-var aPortalCategory> </option> <dtml-else> <option> <dtml-var aPortalCategory> </option> </dtml-if> ... HTH, Shai.
