Hopefully the upcoming > HiperDOM will solve the header/footer split problem. I think a cleaner near-term workaround is to have the standard header explicitly copy all the session key-variable pairs into REQUEST.other: <dtml-in "sessiondatamgr.getSessionData().items()"> <dtml-let k=sequence-key v=sequence-value> <dtml-call "REQUEST.set( k, v )"> </dtml-let> </dtml-in> (This presumes that the getSessionData() return value supplies an items() method, which I haven't actually checked).

ZClass Define Permissions confusion
by Ron Bickers 08 Jan '01

08 Jan '01

After having read the Zope Book Security chapter and various other security howtos, I understand better how permissions apply in ZClass methods and property sheets. However, I'm still confused about a couple things. 1) What is affected by each of the 'Define Permissions' settings in the ZClasses main screen? I created a new permission and assigned it to different things in the list, but the only one that seems to do as I might expect is the 'Create class instances'. I can't figure out what the others do. 2) I have a ZClass that, upon creation of a new instance, creates an Image object in the new instance. Everything works as I would expect, but I'm not sure how (or if) I can define permissions to that object in the ZClass. More specifically, I have to give Image create/change/delete access in the container Folder where the ZClass instance is in order for the user to be able to modify the image inside the ZClass object. Is there a better way using the ZClass permissions? Does this make sense? I understand pretty well the permission system outside of ZClasses, it's just inside them that's giving me a headache. _______________________ Ron Bickers Logic Etc, Inc. rbickers(a)logicetc.com

Re: [Zope] How to call ancestral method in ZClass method?
by Dirksen 08 Jan '01

Hi Steve, Well, if my rack object is stored persistently, I guess no skinscript would get fired, am I right? In that case, I need to override manage_delete, and call it in this statement: <dtml-call "PortalMember.manage_delete()"> Zope complains NameError of PortalMember. If I changed to: <dtml-call "_ZClass_for_DataSkin.manage_delete()"> Zope refuses the upload of the dtml method all together! Any clues?

RSS and JavaScript
by LARRY CHUON 08 Jan '01

08 Jan '01

Hi Zopistas, Happy New Year! I'm working with SiteSummary and would like htmlPreview to grab the URL and open it up in a new window. It's not working correct. I'm unsure how Zope handle javascript either. Any help is greatly appreciated. Below is my htmlPreview. I also tried to put the javascript function (I'm new to js as well) in a file and import it to the same directory as standard_html_header. Then I add <SCRIPT LANGUAGE="JavaScript" SRC="openMe.js"></SCRIPT> to stand_html_header. That doesn't work either. By the way, js doesn't seen to work well in Zope. I could n't find much info on-line. Thanks in advance. <script language="javascript">  </script> <dtml-var "getOwnerDocument()"> <dtml-if channelButton> <dtml-else> <dtml-call "cloneChannelButton()"> </dtml-if> <table bgcolor="#0066CC" cellspacing=0 cellpadding=2 border=0><TR><TD ALIGN="CENTER"> <B><A href="<dtml-var site_url>"><font color="#ffffff"><dtml-var site_title html_quote><font color></A></B> </TD></TR> <TR><TD width=146><TABLE width=146 BGCOLOR="#FFFFFF" border=0 cellpadding=4 cellspacing=0><TR><TD BGCOLOR="#FFFFFF"> <DIV ALIGN="CENTER"></DIV> <dtml-if expr="_['meta_index']==''"> <dtml-in entries> <P><A href="javascript:openMe('<dtml-var url html_quote>')"><dtml-var linktext html_quote></A> <dtml-var summary html_quote></P> </dtml-in> <dtml-else> <dtml-in entries> <P><A href="javascript:openMe('<dtml-var absolute_url>')"><dtml-var title_or_id html_quote></A> <dtml-if summary> <dtml-var summary html_quote> </dtml-if> </P> </dtml-in> </dtml-if> </TD></TR></TABLE> </TD></TR></TABLE>

"SELECT ... AS ..." statement in ZSQL
by Bowyer, Alex 08 Jan '01

08 Jan '01

A simple question, but I can't seem to find a simple answer in any of the documentation... How do you do a SELECT AS statement in a ZSQL method? For example SELECT FirstName + " " + LastName AS FullName Whenever I use AS, I end up getting the SQL error "Two few parameters: x expected" where is the number of AS expressions in my query. I have tried the same query in Access on the same database and it works fine. I even tried to leave Access to do the query and then just let Zope treat the query as a table. SELECT * FROM MyQueryInAccessWhichUsesAsStatements but I get the same error. Can anyone help?

My own alternative interface to a propertysheet in a zClass gets redirected to the original interface
by Max M 08 Jan '01

08 Jan '01

When I make an alternate interface to my properties for a zClass and it then calls manage_editProperties, manage_editProperties redirects me to the original properties page. How can I avoid that? "edit" is the alternative interface dtml method. Do I have to make a new page to avoid it? something like: I thought i could just set: <input type=hidden name=DestinationURL value=edit> in the alternative form. <dtml-call "REQUEST.set('DestinationURL','edit')"> <dtml-call manage_editProperties(REQUEST)> Regards Max m Max M.

Zope 'Best Practices'?
by Steve McMahon 08 Jan '01

08 Jan '01

Is there anything like a Zope 'Best Practices' document or Wiki? One that would encourage use of certain practices, DTML idioms or products, and warn of practices, idioms or products that are known to cause problems down the line or are slated for extinction? I ask this as a new user who's bewildered by the array of Zope tools and products. So, I read of a practice or Product and think 'wow, that's great!' But I have no idea whether it's in common usage and destined to become part of the core, or is headed for replacement or extinction. Thanks!
