ZClass/DTML Document transparency
by Randall Kern 21 Nov '00

21 Nov '00

Hi all, I have a folder (foo) which contains a set of DTML Documents, and instances of a ZClass. >From another DTML document, I enumerate the contents of this folder, using a DTML-IN tag: <dtml-in expr="bar.foo.objectValues()" sort="order"> ... </dtml-in> My problem is with ..., namely dealing with both DTML documents and ZClasses. In the case of DTML Documents, the following works fine: <dtml-var sequence-item> In the case of ZClasses, I have to use something like this: <dtml-with sequence-item> <dtml-var index_html> </dtml-with> So I'm using this: <dtml-if expr="_['sequence-var-meta_type'] == 'DTML Document'"> <dtml-var sequence-item> <dtml-else> <dtml-with sequence-item> <dtml-var index_html> </dtml-with> </dtml-if> But this is rather ugly, and it's the sort of thing one shouldn't have to do in an oo system. So, is there a better way? -Randy

This is definitely not enough information. Either your permissions are strange (you ruled this out) or "standard_html_header" contains something strange that maybe triggers a Zope bug (2.1.6. contained such bug, when you e.g. used 'ZopeFind' or 'ZopeFindAndApply'). We may help you, if you post your "standard_html_header". Dieter

Version Lock/save/discard Problem
by J�lio Dinis Silva 21 Nov '00

21 Nov '00

Hi, I created a version in my zope root in which I've been working for some days. I created some objects on my root folder when working on my version which caused root to became locked. Now I want to save/commit my version. I go to the save/discard form and the save form post looks to work okay, i.e, I have a undo log of this commit and If I try to save again Zope tells me there is nothing else to save in the current version. But... when I try to delete my version I get a VersionLockError, and my root folder is still being locked. Same goes to Discard, i.e, apparentely zope do the save/discard but the locked files/folders continues there. I've tryed with superuser, and even on the Control Panel Version manage, with no luck. I'm using zope222. I'm using latest release of ZEO. I do a pack to my Data.fs on a daily basis. Anyone had this problem, any help?

Re: [Zope] Question about security

Look at the built-in Zope API reference: User object. The User object has methods to read and change the information associated with a user. These methods are (of cause) protected such that only users with high priviledges can execute them. You will need to set a proxy role for the DTML object that calls them, in order to allow less priviledged users to call them. Dieter

Re: [Zope] how-to list all the zclasses constructors ?
by Dieter Maurer 20 Nov '00

Didier Georgieff writes: > I guess it should be simple to generate the list of constructors and > proposing the associated methods, but i just can't figure how to do that ;-< I answer with a general remark: Whenever you see that the Zope management interface does something you are interested in, you can learn how it is done by looking at the DTML source that built the respective management page. In your case, this is "OFS/main.dtml": <SELECT NAME=":method" ONCHANGE="location.href='&dtml-URL1;/'+this.options[this.selectedIndex].value"> <dtml-in filtered_meta_types mapping sort=name> <OPTION value="&dtml.url_quote-action;">&dtml-name; </dtml-in> </SELECT> "filtered_meta_types" is a list of registered meta type objects. A meta type object has attributes "name", the meta type, and "action", the associated constructor. Dieter

Re: [Zope] How exactly do I restart zope?
by Dieter Maurer 20 Nov '00

NYNewMedia writes: > How exactly do I restart zope? Under Unix, "./stop; ./start" in the Zope installation directory. Under Windows: "Shutdown" from Zope's Control Panel (to stop Zope) "start" (in Zope's installation directory) to start Zope. There is a way to start Zope at NT service. I am not an expert for this. Look at the upcoming Zope book (http://www.zope.org/members/michel/ZB) (or something similar). Dieter

The argument to "dtml-in" is a sequence of objects. "dtml-in" iterates over the objects. In each iteration, "dtml-in" exports the current objects attributes into the namespace. Thus, "seq", "vid", ... are probably attributes of your objects. Dieter

The problem was, that "dtml-sendmail" was incompatible with a debugging tool from Shane (I forgot its name, but the list archive will tell it to you). Dieter

Zope / DCOracle / ZOracleDA / Oracle 7.3.3 crash/respawn problem
by Chris Beaumont 20 Nov '00

20 Nov '00

Zopatistas! ;) I am using the most recent versions of (Linux) DCOracle and ZOracleDA to connect my Zope (2.1.6) installation to a copy of Oracle 7.3.3 running on another (Solaris) machine. The Oracle database is rock solid, but I have been having a problem with Zope, one I need to fix. Basically, Zope is occasionally crashing when an SQL query is made. (with valid or invalid syntax.. it doesn't matter) This happens several times a day and makes the website unavailable for two or three minutes while Zope restarts. Obviously, this will not do for a production website. I have noticed that some other people have had this problem and posted to the list in the past. Please, if you know the solution to this..and have a moment, let me know what you did, or think I should do. Compilation tips, or a stable combination of ZOracleDA/DCOracle that I can use... Reliability is very important to this project. Thank you, Chris Beaumont cbeaumon(a)msri.org

snappier zope.org/how to make sites as snappy
by Bak ＠ kedai 20 Nov '00

hi all it looks to me that zope.org is reponding better than previous days. what was done? any tips on how to go about this? my site (http://www.emedia.com.my) currently suffers from long latency between the request and loading the page. tables may be the cause but a request for normal html with no tables (try the printable page) still responded poorly. i've increased the cache numbers in Control_Panel. i've also increased the thread numbers. i've moved graphics to be served by apache. so, i'm pleading for knobs i need to turn, things i need to change, etc i'm using zope2.2.2, ZEO0.41, on rh6.2 with 4G RAM maybe something i overlooked, or don't know thanks
