hi all i've been running zope-2.3.1 for quite some time now. everything went well. but the isp had a power failure today. and after that i kept getting too many open files, esp with access of mailhost, localfs, etc. i've increased the file-max in /proc/sys/fs/file-max. ulimit -a tells me that i can only have 1024 file open. if i restart zope, everything's ok. but the problem will appear again is this the problem? setup - zope-2.3.1 rh 6.2 zeo-0.5 thanks

Re: [Zope] Sorting mod.time with dtml-in?

The value of the "sort" attribute is a comma separated sequence of field names. A field name is either the name of a member or a parameterless function/method (maybe acquired). The sequence is lexicographically sorted with respect to the values of these fields. Thus, you have "sort=bobobase_modification_time". > what's the difference between using sort and sort_expr? the sort=something > has been there since forever :) and i have been using it in my codes. is it > something bad? "sort_expr" is nothing bad. With "sort" your sort specification is constant. You can say, sort first according to "time" then to "id". But you cannot say, sort according to the field name currently held in variable "sort_by". This is necessary for such nice "sort" features found wide spread: click on a column head and the content is sorted with respect to this column... You would use "sort_expr=sort_by" for this. The value of "sort_expr" must evaluate to a sort specification. The specification is interpreted in the same way as when given directly to sort. But it can be computed, it no longer is constant...

Problem migrating a producto to Zope 2.3
by Jorge Ferrer 07 May '01

07 May '01

Hi all, I've developed a product for an Intranet using Zope 2.1 and I'm trying to migrate to Zope 2.3. Almost everything han gone fine as I haven't used any advanced feature, but I have some problems with the ZClasses which inherit from OFS:File. BTW, the product consists on a container ZClass and several other ZClasses which represent different types of documents. Here is what I've done: I installed Zope 2.3.1 on a new machine and installed my product through a distribution file placed on the products directory. When I make an instance of the Container ZClass everything goes well and I can even make instances of some of the other ZClasses. But everytime I try to make an instance of a ZClass which holds a file (by inheriting from OFS:File) I get the following error: =========================== Error Type: TypeError Error Value: unsliceable object Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: HtmlDocumentCreationPage) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: HtmlDocumentCreationPage) File /usr/lib/zope/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: HtmlDocumentCreationPage) File /usr/lib/zope/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: HtmlDocumentCreationPage) File /usr/lib/zope/lib/python/DocumentTemplate/DT_With.py, line 133, in render (Object: HtmlDocument.createInObjectManager(REQUEST['id'], REQUEST)) File /usr/lib/zope/lib/python/DocumentTemplate/DT_Util.py, line 334, in eval (Object: HtmlDocument.createInObjectManager(REQUEST['id'], REQUEST)) (Info: HtmlDocument) File <string>, line 0, in ?

How could I solve it? Any help will be greatly appreciated :-) Jorge

zope: methods and settings
by Jan 07 May '01

07 May '01

hello, i hope someone can help me with two (hopefully) easy questions. 1. i would like to write a method that creates a folder and a default dtml-document. this methods shall be started through a form. at the moment i can use this method in order to create a folder (id is given via form) and a default dtml-document, both in the directory from which the method is started. how can i make settings so that the default dtml-document is created in the new folder, or put into the folder directly after creation? 2. i list zope folders in a navigation. in order to list them in a special order i use an attribute (index). is it possible to display the value of this attribute for each document or folder in the management screen in addition to id and name? thanks a lot in advance, jan

sum up values of two variables
by Marcus Schopen 07 May '01

07 May '01

Hi there, how do one sum up the values of two variables? <dtml-let a="_.len(hello.getPhysicalPath())" b="'BASE'"> <dtml-var a> <dtml-var b> </dtml-let> In other words: the result of _.len(hello.getPhysicalPath()) and the string "BASE" should sum up to one variable, something like <dtml-let a="'BASE'+_.len(hello.getPhysicalPath())"> Thank you Marcus

DateTime() BUG!
by Kai Hofmann 07 May '01

07 May '01

I am still a stupid beginner to Zope, but when I am not completly wrong, then I have found another BUG within ZOPE's DateTime(): (pseudo syntax): enddate=2001/05/04 DateTime().lessThanEqualTo(enddate) results for today (2001/05/04) into FALSE !!! I can only assume that this happens, because the DateTime() returns a date and a time - where enddate is only a date .... Can someone verify this and report the bug to the developers??? Its really important for me!! Thanks Kai -- Institut für Seeverkehrswirtschaft und Logistik http://www.isl.org/ Dipl.-Inform.
