q: How should I get a guaranteed unique id in Zope?
by Farrell, Troy 15 Jan '02

Somebody give the man a cookie! Joe, when you create the table, use the serial type: CREATE TABLE tableLogfileList( logfile_id SERIAL PRIMARY KEY, logfile_path TEXT NOT NULL, logfile_size INTEGER NOT NULL, logfile_time INT8 NOT NULL, logfile_md5 CHAR(32), logfile_errors INT2) Then, to add data, just ignore the id like this: INSERT INTO tableLogfileList ( logfile_path, logfile_size, logfile_time, logfile_md5, logfile_errors ) VALUES ( '/usr/local/logs/new-reports.ibeam.com/vyvx_williamsenl/NetShow.010401-01040 2.log' 11171, 988365240, 'a09ff0a4b11142d03ea940e83a94c82a', 0) See some techdocs on Postgresql (good choice): http://www.postgresql.org/idocs/index.php?datatype.html#DATATYPE-NUMERIC As you can tell, I prefer real world examples :) Troy

RE: RE : [Zope] how to use FSSession
by Paul Zwarts 15 Jan '02

Thierry, Aha.. thats the deal. Gunzip is the compression utility that makes a .gz file, which often is a compressed tar file. AFAIK tar is an age-old utility that is for tape backup drives. A hack to the source allowed a tap file to be a local harddisk file instead, but tar ain't so great. So Gunzip is used on top of that. What you have is the TAR file that is still a compressed file, thus you dont have anything that is usable yet. Reopen this tar file with you decompressor and uncompress that and you should get the desired results. If it wont open the tar file, get winzip or something. You are on a win32 machine yes? If not, use for (l/u)nix: tar -xvf FSESSION.TAR Cheers, Paz -----Original Message----- From: Champier [mailto:Thierry.Champier@grenet.fr] Sent: Tuesday, January 15, 2002 1:46 PM To: 'Paul Zwarts' Subject: RE : [Zope] how to use FSSession Hi Paul, Thanks for your answer..

Products are run by zope on startup by hitting the __init__.py files and then including them as a product in the control panel. Also read the instructions to see if anything was needed to compile first (usually not with products except commonly dbase adapters). Perhaps the restart is what you need on the zope process....

problems with MailHost
by Robert Rottermann 15 Jan '02

15 Jan '02

Hi there, I started to use MailHost on a Zope 2.42 installation. What I do is as follows: <dtml-sendmail mailhost="MailHost"> to: robert(a)redcor.ch subject:Das ist die Testmail from:Halleluja Das ist der Body von dieser Mail </dtml-sendmail> I get a traceback as included. Now my questions: What could be the reason? There were updates to the MailHost. Can I use the ones from the CVS trunk? If not is there a Zope 2.42 (or 2.43) compatible version?

Zcatalog result as sorted list
by Sin Hang Kin 15 Jan '02

15 Jan '02

I would like to emulate the library OPAC search function with Zcatalog : The search operation will be performed as a sort operation on the related key, and the result page with the best result in the middle of the page, the user have the oppunity to browse the result in context (some not satisfy the search critera) and can do prev page next page to continue browsing. Is it possible to do this with Zcatalog? If it is possible, can somebody give an example? Rgs, Kent Sin --------------------------------- kentsin.weblogs.com kentsin.imeme.net

None returned from manage_edit
by Trevor Toenjes 15 Jan '02

15 Jan '02

<dtml-var "myDTML_Method.manage_edit(data, title)"> returns 'None'. It saves content correctly, but why is "None" displayed? And how do I stop it from displaying? 2-fer: What is the syntax to replace myDTML_Method with its id? <dtml-var "id.manage_edit(data, title)"> gives me an AttributeError/class Cachable has no attribute "namemanage_edit". I tested and <dtml-var id> displays the correct value, but how do I call the object via a property using id with manage_edit? TFTH, Trevor

Making products that contain multiple classes
by Jeff Kowalczyk 15 Jan '02

15 Jan '02

I became interested in trying out the new mxm product which offers a reusable base class for products, mxmSimpleItem. I thought I'd try to create the Student/Teacher/Course classes, with which I could later try out the mxmRelation product. (Objects with manageable relationships/references are the thing I've been waiting on to really get started with Zope) I tried to create my three classed in one product. I finally have all classes, but all objectmanager adds call the third classes constructor. If I add a Course, I still get a Teacher in its place, because that's the final definition of the manage_addForm and manage_addAction. Are multiple classes per product something that just isn't done, isn't done with mxm, or is easily done once I know the trick? "__init__.py" -------(some linebreaks removed)------- import Course import Student import Teacher def initialize(context): "This makes the object apear in the product list" context.registerClass( Course.Course, constructors = Course.constructors, icon='images/Course.gif') context.registerClass( Student.Student, constructors = Student.constructors, icon='images/Student.gif') context.registerClass( Teacher.Teacher, constructors = Teacher.constructors, icon='images/Teacher.gif') Course.py ------------------------------------------- from mxm import mxmSimpleItem class Course(mxmSimpleItem.mxmSimpleItem): meta_type = 'Course' _properties = ( {'id':'number', 'type':'int', 'mode':'w'}, {'id':'title', 'type':'string', 'mode':'w'}, {'id':'summary', 'type':'text', 'mode':'w'}, {'id':'building', 'type':'string', 'mode':'w'},) def manage_addAction(self, id=None, REQUEST=None): "Add instance to parent ObjectManager" mxmSimpleItem.addClass(self, id, Course, REQUEST) constructors = (mxmSimpleItem.manage_addForm, manage_addAction) Student.py and Teacher.py are essentially identical, save for the _properties. Can I do anything to the constructors to allow this multi-class/single product package to work?

Re: [Zope] How to create custom folder object by FTP mkdir command
by seb bacon 15 Jan '02

> Thanks for the advice, but I'm afraid it doesn't solve the problem. > > 'mkdir' doesn't triger the PUT action. I put a piece of marker code inside > _default_PUT_factory of NullResource, and it didn't show up when I issued 'mkdir'. Ooops, I wan't paying attention. There is no MKD hook, it is hard-wired to call manage_addFolder (see ZServer/FTPRequest.py). So I suppose you'd have to write your own handler if you need to control this behaviour. Hmm, I'm sure I remember something about this on the CMF list - sorry I haven't time to scour my memory a bit harder. seb > > --- seb bacon <seb(a)jamkit.com> wrote: > > use a PUT_factory handler. search mailing list archives for details. > > > > seb > > > > > > On Mon, 2002-01-14 at 12:15, Dirksen wrote: > > > Hi, > > > > > > 'mkdir' command in a FTP session will create a folder object in Zope.

Best way to serve structured data - pointers needed
by Pertti Kellomäki 15 Jan '02

15 Jan '02

I am contemplating to start a project to build a site for storing and serving structured data (animal training plans in my case). I'm a bit overwhelmed by what's available, so I would appreciate any advice and pointers to Zope products and documentation. The format of the data is fairly simple, basically a datum is just a list of items. Since I want my users to be able to download data in a way that preserves structure, I am leaning towards using XML. I don't really need all the fancy features provided by the various Zope XML products, so I'll probably write my own parser in a couple of lines of Python. The partial requirements are as follows: - It should be possible to view training plans in nicely formatted HTML. - It should also be possible to upload and download training plans as raw XML. - It should be possible to browse plans by categories and by full text search. - Training plans should have relationships (e.g. plan X is derived from plan Y) that users can query (e.g. show me all the training plans derived from Z). I have a rough idea of how to do this in Zope, but I would hate to put a lot of effort into it just to discover that there happens to be a product that would make the whole thing trivial. Thanks, Pertti
