You can have many types of use of Z SQL methods from products: * use a Z SQL method instance located and managed in the Zope hierarchy. Such instances would usually be accessed through acquisition. * instantiate a new Z SQL method instance as part of your product instances * derive one of your product classes from Z SQL methods (though I think this is rather rare) * ....

REQUEST['AUTHENTICATED_USER']. has_permission('Add EW Nav Links', REQUEST.resolve_url(BASE0+getpath(data_record_id_)))) raised the "Unauthorized" exception (according to your traceback). In this expression, only "REQUEST.resolve_url(...)" and maybe "getpath" (if your user can not access the catalog, but that seems unlikely) can raise this exception. "REQUEST" and its methods are public, "has_permission" is public, "BASE0" is public (as part of "REQUEST"). > .... > <dtml-call "REQUEST.set('YihawFolders', [])"> > <dtml-in expr="Catalog({'meta_type':'Yihaw Folder'})"> > <dtml-if "REQUEST['AUTHENTICATED_USER'].has_permission('Add EW Nav Links', > REQUEST.resolve_url(BASE0+getpath(data_record_id_)))"> > <dtml-call "YihawFolders.append(getpath(data_record_id_))"> > </dtml-if> > </dtml-in> As a workaround, you could wrap your "if" into a "dtml-try". If you get an "Unauthorized" exception, it should surely not be in your "YihawFolders" list. Dieter

keeping zope running after closing ssh conection
by David Kelly 01 Apr '01

01 Apr '01

I have just installed zope on a linux ix86 box remotely using ssh...all went perfectly, managed to start zope and connect up to the control panel...all when my ssh connection was still open...as soon as I stopped it I lost contact with zope. Is there a way to start zope so that it stays running after I close the ssh connection? Another thing I need to know is the following: The server is a virtual hosting server and I am wondering if running zope is going to affect the other domains hosted on the same box...I dont want to cause problems....can anyone give me any ideas about how running a site with say 1500/2000 pagereads a day and 1 gig of tranfers per month will do to the environment? Anything I should avoid doing especially?...configurations that can be adjusted? regards to all David

by Jason Cunliffe 01 Apr '01

01 Apr '01

Latest version of Zope 2.3.1 renders an HTML frameset error [Win98se, IE5.1]: The top margin displays the same as the left-hand menu margin. Previous beta versions showed Zope logo etc. The problem lies within the DTML being accessed by the first 2 methods: manage_top_frame manage_menu manage_workspace - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']
