getattr default
by Mitch Model 29 Oct '01

29 Oct '01

What's wrong with the 'getattr' call in this DTML method? I get an error message: "Name not found or not allowed undefined." (using ZDebug). (The problem is not the choice of attribute names -- I get it whatever I type that isn't an attribute in the REQUEST.) If I arrange to get into pdb from this method, the getattr expression works fine. Is this a Zope bug? _____________________________________________________________________ <html> <body> REQUEST does <dtml-if expr="not _.hasattr(REQUEST,'undefined')"> not </dtml-if> have the attribute 'undefined'. <p> value = <dtml-var expr="_.getattr(REQUEST, 'undefined', 'nothing')"> </body> </html> _____________________________________________________________________

ZEO questions:
by Garry Steedman 29 Oct '01

29 Oct '01

Hi, i'm having some problems with a production ZEO system and wanted to ask for some clarifications: box A is running as a ZEO client and box B is running as a ZEO server, HEAD requests reaching box A are served OK, but GET requests are not (500). this suggests to me that the HEAD requests are being served locally, but that GET requests are being sent to box B (where there is a problem). can anyone tell me if this statement is accurate? also, most of the objects served are derived from a ZClass product. now, when GET requests are for pdf files (which are file objects), they return OK, but GET requests for the ZClass-based content objects return 500. does this suggest a problem with the ZClass product or not? these may be dumb questions but any feedback would be appreciated... cheers, Garry +-------------------------------------------+ Garry Steedman mailto:gs@styrax.com Styrax Associates http://www.styrax.com/ "The Good Man has no shape." +-------------------------------------------+

RE: [Zope] can not login from localhost
by Sin Hang Kin 29 Oct '01

29 Oct '01

I can get the authentication box, but the password is rejected. The same u/p is accepted when try from another box on the local subnet. So, i think the zpasswd.py does not help here. I do have try both http://127.0.0.1:8080/manage as well as http://192.168.83.121:8080/manage from the box. Both fail. How can I trace this? Can I turn on some loging or tracing on the zope server? BTW, zope is running as a service on the win2000 box, not zeo is used. Rgs, Kent Sin --------------------------------- kentsin.weblogs.com kentsin.imeme.net

NEWBIE: manage_delObject, manage_delProperties?
by Michael 29 Oct '01

29 Oct '01

I'm trying to figure out how to delete an object from Zope. I use manage_editProperties to add and index, and manage_changeProperties to edit and reindex, that all works fine, but I'm not sure how to delete. I am using : <dtml-call "propertysheets.entry_info.manage_delProperties(REQUEST)"> and this just gives me an error message and I also tried: <dtml-call "propertysheets.entry_info.manage_delObject(REQUEST)"> but that errors out too. I am using this on a database object that contains the fields: id (this is set by ZopeTime) first_name last_name email_address mail_request interest_area Can anybody point out what I am doing wrong? Michael

Aha! I should be using REQUEST as an ordinary dictionary, with has_key, get, etc., rather than the _ methods such as hasattr & getattr. Thanks. -- --- Mitchell

can not use umlaute with structered text
by Robert Rottermann 29 Oct '01

29 Oct '01

Hi there, I found out that as soon a text contains umlauts the codes to change its formatting like **xxx** do not work anymore. I was digging in the source and found locale.setlocale. However this function does not work. Calling it creates a traceback saying that the local can not be changed. How can this function be used. Or is there an other way to be able to use umlauts? thanks Robert

Two Questions
by Ben Ocean 29 Oct '01

29 Oct '01

Hi; 1. I have pages with inline frames. All call a css document from the standard_html_header. For the framed pages I need to put a background image that must be referenced from the css document; however I don't want this to happen for the other pages. All framed pages end with *_frame*. I would like to write a <dtml-if> tag that would read the url of the calling document and determine if it is a framed page. (Of course, I could simply write a separate standard_html_header, but I'd like to learn something here.) How do I do this? 2. The image that is called in the aforementioned css document is generated by a certain dtml method which randomly calls other dtml methods (which each reference a specific image) out of a certain folder. I need to reference the name of the method in the framed document; however, if I simply re-call the dtml method that randomly calls the others, I'll end up with 2 different documents (and therefore names), and I must reference the same document. How do I do this? TIA, BenO

Re: [Zope] ZopeTime Error

---------- Forwarded Message ---------- Subject: Re: [Zope] ZopeTime Error Date: Mon, 29 Oct 2001 11:24:14 -0600 From: Mike Doanh Tran <mtran(a)shufflemasterrd.com> To: complaw(a)hal-pc.org Ron, I tried your suggestions. I gave my defined user the same permission setting in the security tab as the Manager Role( basically everything). But i still get the same error. The ZopeTime() method is a call to the python DateTime Object, it does not relate to my installed Product. I am running Zope 2.4.1 on Redhat 7.1 with Python 2.1.1 using Apache rewrite engine rule . I added a "User Defined Role" in the security tab. Could it be that my Defined User does not have the permission to call the python's ZopeTime().Date()? Does the linux permission on /usr/local/zope/lib/python have to set to a certain RWE by the webserver? Does anyone knows? Thanks for any suggesstions.
