Using FTP to connect to Zope server from (g)VIM
by Phil Harris 25 Mar '02

25 Mar '02

Hi all, My intellect was piqued recently by a discussion on the list about editors for Zope etc. I remember some people saynig that VIM was good, to which my response was, 'Yeah but there's no FTP built in'. Someone then responded with a few scripts to do it. Well I thought they were a bit cumbersome, so I wrote my own. ftpopen.py and ftpsave.py. If you have a VIM executable with Python support built in then these run from within VIM and allow you to open/save file from/to Zope seamlessly. (I have them on a menu in GVIM for instance) I'll put the files up on my Zope Members bit (http://www.zope.org/Members/philh) along with a few instructions. If anybody can think of any enhancements then please let me know and I'll see if I can work them in. I hope these will be useful to someone. See ya Phil phil.harris(a)zope.co.uk

I currently have Zope and Python installed from the source code from the excellent instructions by JShell. But there is one little problem....CPU Utilization shoots above 97% as soon as I access the management screen. If anybody has any ideas or solutions.

Why not use ZClient to make the request to do the mailout? It can just happily sit there for half a day (or whatever) chugging along, without screwing up if your browser goes away.

Re: [Zope] Retrieving the week number with DateTime
by David Coe 20 Nov '00

20 Nov '00

I suspect there is no 'standard' definition of week number. E.g. if the year begins on a Wednesday, is the following Monday part of week 1 or week 2? Once you decide, you can design a calculation starting with "some_date_object.dayOfYear()" which will give you the day number in the range 1 to 365 (or 366). The simplest algorithm would be to say days 1-7 are week 1, 8-14 are week 2, etc. In that case ((some_date_object.dayOfYear() - 1) / 7) + 1 (or in dtml) <dtml-var "((some_date_object.dayOfYear() - 1) / 7) + 1"> will compute a week number (in the range 1 to 53). If your weeks must begin on Sundays, or Mondays, or whatever, you'll have to first request the dow() from the first day of the relevant year, and do a calculation based on how far into the week the first calendar day of the year falls. If you want help with that, describe the algorithm you want to use. Good luck.

newbie: comparing dates?
by Georg Rellensmann 08 Nov '00

08 Nov '00

Hi all, another newbie-question: - I created a zclass with three date properties. - Now I´d like to display the most recent of these dates in directory-listings etc. QUESTION 1: How do I compare dates in dtml code? QUESTION 2: How do I exclude empty values from processing? (I installed rapto´s null date-patch, seemed to work fine; for that patch see: http://www.zope.org/Members/rapto/nullDate?pp=1) regards, -georg.rellensmann-

Hi, I am working with zope and I want to securize my access to the data stored in a Sybase Server. So I am trying to do all my SQL requests by using stored procédures. The only thing that goes wrong is that I don't know how to make a call to a Sybase Stored Procedure within Zope. Can anyone help me ?

RE: [Zope] How to render a HTMLFile in a method in a product
by Max Møller Rasmussen 06 Nov '00

06 Nov '00

>From: Chris Withers [mailto:chrisw@nipltd.com] I got this answer to my question about how to render a dtml document from a method. >testisDocTemp = 1 >def test(self,ignored,md): > " A simple test method " > return HTMLFile('skins/' + self.skin, globals())(None,md) And I have been busy trying to read the source code to understand the advise: As far as I understand the story goes a little like this: HTMLFile returns an object (through inheritance) "String" in file "DT_String.py" that has "__call__()" implemented, which means that the class can be called as a function... Hmm ... I had actually not seen this method used in Python before. def __call__(self,client=None,mapping={},**kw): This method accepts an object in which it will look up values to insert in the dtml file, and a mapping object (dictionary) that also will look up values to insert. So i guess that is what (None,md) does. But I dont understand what "ignored" does in my method, as it is unused, unless it is used by md >def test(self,ignored,md): Furthermore I dont understand what md is. Some kind of mapping object naturally, but where does it come from? Also what is testisDocTemp supposed to do? If I grep the source a "isDocTemp" shows up but is isn't easy to see what this does either. Regards Max M
