A good time to set HTTP_ACCEPT_LANGUAGE
by Peter Bengtsson 01 Feb '07

01 Feb '07

My multilingo app now works with PlacelessTranslationService quite fine. If you change your browser setting with about:config you get the website in different languages. Neat! However, what if you're in an internet cafe in Kenya using a Zulu web browser and you want the pages to appear in English for example? One solution is to do this:: def __before_publishing_traverse__(self, object, REQUEST): lang = self.getUserCookieSettingLang(default='en') # 1. REQUEST.environ['HTTP_ACCEPT_LANGUAGE'] = lang # 1. Trust that this is my custom function for finding out # which language they really want to use when logged in. Problems with this approach: 1. It has to be done for every object I publish including images, css etc. 2. It feels slightly risky to change the REQUEST.environ object. Thoughts? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

Zope 2.9.5 -> 2.9.6 DateTime Change
by Brian Brinegar 01 Feb '07

01 Feb '07

Today I started testing Zope 2.9.6. After the upgrade I noticed that some calendar data generated from Oracle was wrong. After some investigation I found that Zope 2.9.6 seems to assign a timezone of GMT+0 when none is specified rather than using the server's timezone. For example, the following SQL query to an oracle database: select TO_DATE('12-13-2006 01:00','MM-DD-YYYY HH:MI') from dual Under 2.9.5 returns: 2006/12/13 01:00:00 US/Eastern Under 2.9.6 returns: 2006/12/13 01:00:00 GMT+0 There was clearly no time zone defined in the query, and it's the same Oracle server. Is this an intended change? We have hundreds of developers working independently within our system so it's not possible to adapt each application to account for this change. Any advice on moving to Zope 2.9.6? In the mean time I my try to back port specific bug fixes into 2.9.5. Thank you, -- Brian Brinegar Web Systems Developer Engineering Computer Network

RE: [Zope] Re: FW: Problem Starting Zope after Installation

Eric ~ My Zope is up and running, thanks to you! It turned out there were two other Python-related environment variables, both of which I deleted: > PYTHONPATH = %SystemDrive%\IBMTOOLS\utils\support;%SystemDrive%\IBMTOOLS\utils\logger > PYTHONCASEOK = 1 So, just for the record (and the next unsuspecting ThinkPadder who comes along), in all 4 ThinkPad variables had to go - the two above, plus the first two you told me about: > TCL_LIBRARY=C:\IBMTOOLS\Python22\tcl\tcl8.4 > TK_LIBRARY=C:\IBMTOOLS\Python22\tcl\tk8.4 ~ Thanks a million ~ Ken -----Original Message----- From: Eric Fu [mailto:ericfu88@gmail.com] Sent: Wednesday, January 31, 2007 7:32 PM To: Ken Winter Subject: Re: [Zope] Re: FW: Problem Starting Zope after Installation Do you have some environment variable called 'PYHTHONIGNORECASE' (or something like that)?

Is there any way to turn off the publishing of external methods to the web in Zope?
by Mark, Jonathan (Integic) 31 Jan '07

31 Jan '07

I have an external method which uses eval(). I would like to prevent anyone from calling this method from inside a URL, e.g., myzopesite/myexternalmethod?myvar=deletemyfiles() Rather, I wish for only Zope objects such as Python Scripts to be able to call this external method. Is there any way to turn off the publishing of external methods to the web in Zope?
