Hi and thanks, I want to view images in a local fs on a web page so i have: <dtml-with images> <dtml-in images start=0 size=50 orphan=0 reverse> <img src="<dtml-var "(THE IMAGE ID'S)">"><br> </dtml-in> </dtml-with> I've read that I can get the filenames as id's by using getObject, but I can't seem to make it work.

Hi! I've just wondered how one can change (Zope 2.1.6) the Roles of a user without changing the password?

Namespaces? DTML Methods? Properties? Oh my.
by Gary Perez 19 May '00

19 May '00

Hello all. First, a warning: I'm probably the newest of all Zope newbies. I'll do my best to formulate some semblance of an intelligent question. I'm having a namespace meltdown. Here's what's going on... I have a ZClass called "Company" which has attribute "id", and a ZClass called "Project" which has attribute "CompanyID" among others. I'm trying to call and render only those Projects that have a CompanyID that matches the Company object's "id" attribute. I'm doing this in the "index_html" of the Company ZClass by calling a DTML Method "retrieveCompanyProjects"... which resides in the folder "Company_List". Here's the pertinent tree structure: / Company_List/ Company1/ Company2/ retrieveCompanyProjects (DTML Method) Control Panel/ Products/ ASTi/ Company (ZClass) index_html Project (ZClass) Projects/ Project1/ Project2/ Now... the procedure is successful when rendering only those Projects that match a specific FSSession userid, as such: ## DTML Method 1 Excerpt: <dtml-in "Projects.retrieveUsersProjects(_.None, _)"> ## "retrieveUsersProjects" DTML Method Excerpt: <dtml-call "REQUEST.set('list', [])"> <dtml-in "Projects.objectItems(['Project'])"> <dtml-with sequence-item> <dtml-if "Engineer == FSSession['userid']"> <dtml-let x=sequence-key> <dtml-call "list.append(absolute_url())"> </dtml-let> succeed <dtml-var ApplicationEngineer>, <dtml-var "this()"> <dtml-else> fail <dtml-var ApplicationEngineer> </dtml-if> </dtml-with> </dtml-in> ## I've tried to use the same mechanism in the "retrieveCompanyProjects" DTML Method, and here's where the namespace meltdown turns my brain to mush. Here's the "retrieveCompanyProjects" DTML Method, which (to reiterate) is called from the "index_html" method inside the Company ZClass: ## <dtml-call "REQUEST.set('list', [])"> <dtml-in "Projects.objectItems(['Project'])"> <dtml-with sequence-item> <dtml-if "CompanyID == COMPANY_ATTRIBUTE_NAMED_ID"> <dtml-let x=sequence-key> <dtml-call "list.append(absolute_url())"> </dtml-let> succeed <dtml-var CompanyID>, <dtml-var "this()"> <dtml-else> fail <dtml-var CompanyID> </dtml-if> </dtml-with> </dtml-in> <dtml-return "REQUEST['list']"> ## My problem is that I can't for the life of me figure out what to replace the "COMPANY_ATTRIBUTE_NAMED_ID" with in order to make it work. User-specific is easy... it's simply FSSession['userid']. Due to the position of the <dtml-if> following the <dtml-in>, however, I'm in the namespace of Projects, right? That being considered, the property "id" is at that point the "id" of the Project, and not of the Company anymore, no? How can I go out, and snag a Company's property "id" from within that namespace? Can I do a <dtml-with> ??? </dtml-with> to pop the Company namespace on the top of the stack & kick it out after getting the "id"? Or, alternatively, is there a way that I can pass the variable "id" from the Company namespace into the DTML method so it's there, recognized, and used to filter the Projects? Sorry this was so long, but any help would be greatly appreciated. I'm confused. Thanks, -Gary -- Gary Perez Advanced Simulation Technology, inc. http://www.asti-usa.com/

If the frameset is already displayed (i.e. the search form, too, is in the frameset), you may use the HTML 4.0 "target" attribute to tell the browser to display the return page in this "target" frame. I the result should go into a frame in a newly created frameset, you problably must use DTML to dynamically create the frame set and include the REQUEST parameters in the source url of your report page frame.

Zope SQL Database Connection
by joel grimes 19 May '00

19 May '00

<Beginner Question> I'm trying to add a database connection to a site (my first one). I tried adding a SQL Method and am told I need to add a Zope Database Connection. I can't find that in the list of available objects. Can someone direct me to a resource that explains how? It's not mentioned in the quick start guide. I'll be using an Access or SQL Server Database. Oh yeah...and what the heck is a Z Gadfly Database Connection? Thanks, Joel Grimes joelgrimes(a)hotmail.com ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

ZPygreSQLDA Help
by Kenny Smit 19 May '00

19 May '00

I am running zope 2.1.6 and Postgres 6.5.3 on Free BSD 4 and attempting to get these to two working together with little luck. After a couple of changes to the make file I was able to create the _pgmodule.so file. I moved this file up one directory as the directions instructed. However even after doing all of this it is still showing in control panel as a broken product. I am running this on a Free BSD 4 machine. I currently have this product working fine on our linux box. Thinking that the problem may be with owner ship I have made sure that it is owned by nobody and group ownership is soul (my personal username). It seems that the .so file is correct as I can import _pg in python without a problem. I am not sure how helpful the message below will be to you but I included it in hopes it may make more sense to you :). Traceback (innermost last): File "/usr/zope/lib/python/OFS/Application.py", line 387, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/zope/lib/python/Products/ZPyGreSQLDA/__init__.py", line 89, in ? import sys, os, Globals, DA File "/usr/zope/lib/python/Products/ZPyGreSQLDA/DA.py", line 91, in ? from db import DB File "/usr/zope/lib/python/Products/ZPyGreSQLDA/db.py", line 89, in ? import _pg, regex, sys, types ImportError: /usr/zope/lib/python/Products/ZPyGreSQLDA/_pgmodule.so: ELF file ABI version invalid. I would like to thank you in advance for your help.

Representing rows from a ZSQL method
by Juan Carlos Coruña 19 May '00

19 May '00

Hi all! I must manage a lot of information coming from a database and represent it on the web. For example: -Displaying an order on the web with the order header (consisting of the client name, address, ZIP, etc.) and the order lines with the products to purchase. -Displaying a list of invoices between two dates with several columns (Invoice date, amount, VAT, invoice number, etc.). -Displaying a price list of our products with several columns (reference, description, price, weight, etc.) and grouping the products by different criteria. For example inserting a row with the brandname of the next group of products or inserting a row of the product type. Is there a product for zope to acomplish this?

Nesting ZClasses
by David Holden 19 May '00

19 May '00

Hi, I'm working throw the ZDevelopers guide, and want to try using nested ZClasses, e.g. I have a product CDcollection, which contains a ZClass ZCDcollection, I want ZCDcollection to contain instances of a sub class ZCDinformation (for individual CDs). According to the Doc's I should make the top class "ZCDcollection" a sub class of object manager and then create the subclass "ZCDinformation" in the methods tab of the ZCDcollection class. The docs say that Zope should then make this available in the subobjects tab of "ZCDcollection" but it doesn't. The only way I can get the ZCDinformation class avialable in the subobjects tab of the ZCDcollection class is if I make the ZCDinformation class at the same level as the ZCDcollection class, i.e. under product/CDcollection folder. in summary Products/CDcollection/ZCDcollection Products/CDcollection/ZCDinformation makes ZCDinformation avialable to the ZCDcollection subobjects tab but Products/CDcollection/ZCDcollection/ZCDinformation does not? Can any one explain this? thanks in advance, Dave.
