Programmatically: zclasses and images
by brocken22＠gmx.de 11 Oct '00

11 Oct '00

Hallo, I've got two problems cutting my nerves: The site-structure is organized in a way that zclasses can be added programmatically(the user decides by clicking on a tree-list where to add the classes) The 1. problem is that I can't manage to pass the URL of the selected object to add the zclass in the requested place. Therefore I'm not using one script for adding the instances, but every zclass is holding the constructormethod(you're clicking on the tree and the selected zclass is responding with the addFormular and later with the addConstructor). This way is working.I'm not very happy about it because every zclass is created with methods that I think can be avoided. My biggest problem is that I can't manage to add images in the new zclass. That's the script: <dtml- with "manage_addProduct['Zzzz']"> <dtml-call "ZZZsite_add(_.None, _, NoRedir=1)"> <dtml-call "manage_addImage(pictureName,picture)"> </dtml-with> This is a zclassMethod and the formMethod(also inside the zclass)passes the 'picture' and 'picturename' variables! The ZZZsite_add method is the usual-one. I think it's an acquisition problem. -- Sent through GMX FreeMail - http://www.gmx.net

Zope.org Feature Request - Product Download Counter
by J. Atwood 11 Oct '00

11 Oct '00

It would be really nice to know how many people are downloading the products. This would also be a great feature to add to the actual Zope distribution. I know you could get this from the logs (easily) but you could also add a small counter to the product 'view' method, something along the lines of what is in the Simple Url products (BTW one of my favorites) and make it something you can turn on or off for your products. <dtml-call "REQUEST.set('hitcount', hitcount + 1)"> <dtml-call "propertysheets.public.manage_editProperties(REQUEST)"> <dtml-call "RESPONSE.redirect(url)"> Thanks, J

How to see if two objects are the same
by Ron Bickers 10 Oct '00

10 Oct '00

I want to see if an object is the one aqcuired from the root, but I'm hitting walls. <dtml-var "myObject"> <dtml-var "PARENTS[-1].myObject"> <dtml-var "PARENTS[-1].myObject is myObject"> This returns the following when in the root folder context: <TinyTable instance at 8684ad8> <TinyTable instance at 8684ad8> 0 It returns the following in a folder where there is another myObject: <TinyTable instance at 8684ad8> <TinyTable instance at 86709f8> 0 What am I missing in the comparison? Thanks! _______________________ Ron Bickers Logic Etc, Inc. rbickers(a)logicetc.com

Second question ?=)
by //www.alomega.com/ 10 Oct '00

10 Oct '00

This is my second question: Id like to run a <dtml-in sqlquerymethod> with specific parameters to its namespace This is the deal I want to construct a dropdown list, with all values retrieved from a SQL stored procedure, so if I open the form with no variables, all of them appear, but if i submit the form to itself, the variable gets passed on to parameters, and the SQL query receives it because it's on its parameter list, and filters the query. I don't want to alter the SQL query methods to fetch all data, but i'd like to override the values of its namespace so I can specify NULL and get all data, and in calling method compare each data in the <dtml in> loop to insert a selected property in the dropdown object that matches the existing variable. Any pointers? ---------------------------------------------------------- Universidad Federico Santa Maria - Campus Guayaquil

Re: [Zope] Where is the difference between URL0 and BASE3
by Dieter Maurer 10 Oct '00

URLn removes "n" URL path components from the right, BASEn consists of the first "n+1" or "n+2" URL components. Thus, if you URL is "host/u1/u2/..../un", then URL0 is URL, URL1 is the last component "un" removed, ULR2 is the last two components "u{n-1}/un" removed etc. Usually (unless you access Zope via CGI), BASE0=BASE1=host. BASE2 is "host/u1", BASE3 is "host/u1/u2" etc. If your URL has 3 components, then URL0 and BASE3 are identical, otherwise, they are not. Dieter

Re: [Zope] pop back namespace from stack ?

You can not (from DTML). The caller must help you, e.g. by: calling method: .... <dtml-let caller_id= document_id> <dtml-var called_method> </dtml-let> ..... called method: ... <dtml-var caller_id> ... Dieter

There, ZODBCDA was blocking during database queries. Maybe, your database adapter has similar problems. Dieter

Re: [Zope] fmt=structured-text seems wrongish

And shouldn't the fmt specification tell how > myDoc.description is to be presented instead of how it is stored? I agree with you that "fmt" should specify how the value should be formatted and not how it is stored. > For example, let's say I can choose to store description as plain text, as > structured text, or as html. Regardless of how it is stored, I might want > to ask for it as: > > fmt=raw in case I want to edit it > fmt=html in case I want to send it to a browser I fear, the "fmt" machinery will not know, how the value is marked up (plain/stx/html). This knowledge would be necessary for a format change. Currently, I would say, this is not a task for the "fmt" argument but for the application. Dieter

Fighting htmllib in external method
by Jason Spisak 10 Oct '00

10 Oct '00

Howdy Zopsters, I want to catalog some html files but I want to strip the html tags out. htmlparser does a good job of that, but when I try to acces that from an external method, I run into trouble. import htmllib import formatter def index(self, html): fmtr = formatter.AbstractFormatter(formatter.DumbWriter(file)) p = htmllib.HTMLParser(fmtr) return p.feed(html) Since the DumbWriter uses stdout, this returns None. When I try to write to a temporary file, or pipe I get 'bad file descriptor' errors because of the way external method function I guess. Any help would really be appreciated. All my best, Jason Spisak 444(a)hiretechs.com
