RFC: is this the best way to make a referal app and a "jump" nav menu nav menu
by George Donnelly 01 Jul '00

01 Jul '00

Basically i would like people's opinions as to whether i built these things in the "right" way or not. tia! >jump menu *created a selection list and told it to pass a variable (the url of the selected item) called "url" to a method called "jump" which consists of the following: <dtml-call "RESPONSE.redirect(url)"> its a little slow but it works :-) >referral product (as in http://www.recommend-it.com/) i pass the variables on the first page (where people enter name, email, and up to 5 of their friends email addresses) to a method called success here's the problem i think: since i am enabling people to email up to 5 friends, i've got 5 copies of the same email message in the success method inside the sendmail tags. the last 4 are in if statements. i know there must be a better way but i really have no idea. any help? (btw if anybody wants to use these things just email me and ill send you the terribly simple yet useful code. :-) tia!

Removing part of a string (in an URL)
by Walter A. Aprile 01 Jul '00

01 Jul '00

Hi, more newbie questions, I am afraid. I have a ZCatalog result form that boringly forms links this way: <dtml-var "busca.getpath(data_record_id_)"> Due to the way my site is organized, the URL I get has an unwanted part at the beginning. The part is always the same size, and the same string in fact. How do I remove it ? For example, the URL is http://zorba.com.mx:8080/Zorba/busca/Zorba/cacharrito/prueba ^ and I would like to cut it here | and turn it into /Zorba/cacharrito/prueba The problem is that the URL above is still valid, but if I do another search then the same /Zorba/busca gets added, and it gets longer and longer, besides messing up my breadcrumb trail. I tried using a regular expression method, but I do not really know Python (not yet !), so it did not work. Thank you very much Walter -- Vita brevis, ars longa, occasio celeris, experimentum periculosum, judicium difficile.

Oracle 8i problem: OCIEnvInit failed
by Dave Parker 01 Jul '00

01 Jul '00

I'm having trouble figuring this out - I've got a zope 2.1.4 server that I'm trying to get to work with DCOracle 1.3.1 b1, ZOracleDA 2.2.0 b1, Oracle 8i client and Oracle 8 server on a RH 6.1 Linux machine. The DCOracle test routine *does* work - it connects and says as much. Within Zope I'm getting some frustrating behavior however. I'm starting Zope with the "start" script in an environment that has ORACLE_HOME set just as it was for the DCOracle test script. The product looks OK in the control panel. I can make an instance of it, but if I have "connect immediately" turned on Zope *dies* and I get "OCIEnvInit failed, oci_8.c:220" in the terminal that I started Zope on. If I have "connect immediately" turned off, I can create the instance. But whenever I try to connect I get the same problem - Zope dies with the OCIEnvInit failed error. Any clues folks? I'm seriously pressed for time here - anything you have would be most appreciated! Thanks, Dave Parker

Unique id product
by Sin Hang Kin 01 Jul '00

Hi, I want to develope a unique sequence id generator product, I have the following code def newid(self, increment=1): """ return new id """ self.counter = self.counter+increment return self.counter I am not quite sure if this works when more than one process asking for a newid concurrently. Is that zodb automatically serial all transaction? BTW, how can I obtain a local copy of the zodb uml model? Rgs, Kent Sin --------------------------------- kentsin.weblogs.com kentsin.imeme.net

Search Interface
by David Trudgett 30 Jun '00

30 Jun '00

I'm having some trouble setting up a search interface into a ZCatalog. I want to create a text index on the contents of my DTML documents, but I can't seem to get it to work. It search on title just fine. I think my problem is that I don't know how to create the right index, and what to call it (how the body or text of a DTML document is referenced). Can anyone enlighten me about this? I might be going blind, but I haven't come across anything in the documentation so far that answers my question. I'm about to resort to reading the Zope source! (which I think I will need to do sooner or later anyway, to get a better understanding of how it all works). Thanks for any assistance. David Trudgett

Re: [Zope] Why can't I subclass a ZSQLMethod?
by Ivan Raikov 30 Jun '00

30 Jun '00

Why don't you create a ZClass and make the ZSQLMethod to be one of its methods? Then the ZClass can provide the user interface to the SQL query and the result set.

You do not pass the objects "par1", "par2" and "par3" but the literal strings 'par1', 'par2' and 'par3'. At least for "par3", this will not be what you want. Try: <dtml-with "PARENTS[2]"> <td><dtml-var "mtdCreate(_.None, _, qry_item='par1',qry_table='par2', list_name=par3)"> </td></tr> </dtml-with> I.e., remove the quotes from "par3" (maybe the other "par", too).
