how-to list all the zclasses constructors ?
by Didier Georgieff 20 Nov '00

20 Nov '00

Hello, I need to have a simple list choice for adding ZClasses instances instead of using manage_workspace (because the users are really *end* users and speaks french). We are using Yihaw and extending it with news Zclasses. So we have a Zclass, a my_addForm in french , my_add methods and a my_factory. All works fine when i call that directly from DTML giving the method name in **hard coding**, and works fine when i use manage_workspace (it propose all my new factories in the Add list but in english with zope interface). What i want is getting the list of factories (automatically) in my personnalized page (instead of hard coding it). 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 ;-< Any tip and/or explanation would be welcome, and i'll summarize all that in an how-to (in complement of the Adding Zclasses instances programatically) Thanks in advance. -- Didier Georgieff DDAF du Bas-Rhin - Cellule SIG 2, rue des Mineurs 67070 Strasbourg Cedex tél : 03.88.25.20.33 - fax : 03.88.25.20.01 email : didier.georgieff(a)agriculture.gouv.fr SIT du Bas-Rhin : http://www.bas-rhin.sit.gouv.fr GéoWeb http://sertit10.u-strasbg.fr

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.

No, as far as I am concerned. Since I am using Zope (and trying to learn Java), the object-oriented approach is great for not having to search/replace anymore. I really do not know any situation where s/r is still needed. The people who fill in content in our company have ZClass-Interfaces, and they only insert actual content. Another thought: If Zope would offer s/r, then a bunch of programmers would stick in their bad behaviour _not_ implementing <dtml-var>'s, because "it's easy and effortless to replace everything from 'Copyright 2000' to 'Copyright 2001'". But think of it: Maybe this string is correct somewhere and SHOULD stay the same. So s/r is at least inefficient, because you'd have to check every file whether Zope should replace or not.

Is there any way to do a 'search and replace' in a Zope folder (and it's subfolders)? TIA Lee Hum Communications Ltd.

Web mail with POP3
by Aleksander Salwa 20 Nov '00

20 Nov '00

I need to build a web mail product with pop3 back-end. There is WorldPilot, but AFAIK it has no pop3 support. I'm thinking about taking web inteface/application design from WorldPilot and writing code to talk to pop3 server (probably based on POPMail product). Is this a good approach, or someone already has wrote something like this for Zope ? ololo(a)zeus.polsl.gliwice.pl /--------------------------------------\ | `long long long' is too long for GCC | \--------------------------------------/

problem creating properties via python methods
by belitski 20 Nov '00

20 Nov '00

Hi! In the following code stored in a DTML Method I create DTMLDocument called hello and then I want to add it some properties. The error is that those properties get created in the parent folder object and not in my "hello" DTMLDocument although I try to reference the self parameter to "hello" using the with tag. I would appreciate any hints to solve it. Thank you in advance. :-) Andrei <dtml-call "manage_addDTMLDocument('hello', REQUEST['new_name'])"> <dtml-comment>REQUEST wichtig sonst properties von parent object</dtml-comment> <dtml-with Test> <dtml-with hello> <dtml-call "manage_addProperty( id='company_name', value=REQUEST['new_name'], type='text', REQUEST=REQUEST)"> <dtml-call "manage_addProperty( id='message', value=REQUEST['new_message'], type='text', REQUEST=REQUEST)"> <dtml-call "manage_addProperty( id='contact_phone', value=REQUEST['new_phone'], type='text', REQUEST=REQUEST)"> </dtml-with> </dtml-with> <dtml-call "RESPONSE.redirect('manage_main?update_menu=1')">

getitem problem
by Matt 20 Nov '00

20 Nov '00

why does the first work and not the second ? staticProperties is a dtmlDocument and container_metatype is a property of it. 1) <dtml-if "meta_type == staticProperties.container_metatype"> this is a container <dtml-elif "meta_type == 'Folder'"> this is a folder <dtml-else> this is not a container </dtml-if> 2) <dtml-if "meta_type == _.getitem('staticProperties.container_metatype')"> this is a container <dtml-elif "meta_type == 'Folder'"> this is a folder <dtml-else> this is not a container </dtml-if> the same will happen with : <dtml-var "staticProperties.container_metatype"> <br> <dtml-var "_.getitem('staticProperties.container_metatype',1)"> regards Matt
