using dollars_and_cents in python script?
by Jeff Kowalczyk 16 Jan '03

16 Jan '03

What am I missing when importing and using methods like dollars_and_cents() in python scripts? What works for me in ZPT Tal... tal:define="pss modules/Products/PythonScripts/standard; value 47.5" tal:content="python:pss.dollars_and_cents(value)" Isn't working in PythonScripts. from Products.PythonScripts.Standard import dollars_and_cents value = 47.5 print "Value:", dollars_and_cents(value) return printed I've also tried this line in GlobalScripts\__init__.py: allow_module('Products.PythonScript.Standard') but I still can't import from Standard. Any ideas? Is this a security design decision, that TAL has access to Standard, but scripts do not, or is it just a technical import mistake I'm makeing? Thanks.

re: Length of results set

Hi again, Maybe I'd better re-phrase my question. I think it will be easy for many of you, maybe even me.. I had too much coffee last night. How do you get the length of results for a <dtml-if> inside a <dtml-in> ? It can't really have anything to do with <sequence-length>, and I've tried a few ideas using "._len(...)" but to no avail. In Beno's now famous example, how to report the number of objects where "folder==lang" ? > <dtml-let lang="REQUEST.get('HTTP_ACCEPT_LANGUAGE','en-us')"> > <dtml-in objectValues> > <dtml-let folder=id> > <dtml-let langShort=lang[2:]> > <dtml-var langShort> > <dtml-if expr="folder==lang"> > <dtml-var lang> > </dtml-if> > </dtml-let> > </dtml-let> > </dtml-in> > </dtml-let> Like Beno, I'll write a Python script next time, I promise... Thanks! Ken

External Editor and OpenOffice: workaround
by Ivo van der Wijk 16 Jan '03

16 Jan '03

Hi all, External Editor won't work with OpenOffice because OpenOffice detaches immediately (or terminates after notifying the running instance to open the file). I've hacked together a solution for this problem. It should be applicable to all detaching programs that cannot be forced to run in the foreground. It requires a working 'lsof' on your system (i.e. Linux, but I understand lsof is available for several unices) More info: http://vanderwijk.info/python/ExternalEditor Cheers Ivo -- Drs.

object id's and request vars
by Lieven Van Acker 16 Jan '03

16 Jan '03

Hi, I need to include a fragment identified by a request var in a PT . This is something I tried. I believe there must be an easier way to achieve this. <SPAN tal:condition="exists:request/form/var" tal:repeat="x python:here.objectItems()"> <P tal:condition="python:x[0]==request.form['var']" tal:define="y python:x[1]" tal:replace="structure y"> </P> </SPAN> where the request is issued as <A tal:attributes="href python:here.id + '?var=test' "> inluded </A> Regards, Lieven -- Lieven Van Acker <lieven(a)elisa.be> ELiSA

secure password transmission
by Raphael Arlitt 16 Jan '03

16 Jan '03

I am a bit doubtful about the insecure password transmission in zope. How can I secure this action for user logins and for FTP access to the sites. I know I can limit the site access to a domain, but still I consider that as being to dangerous. Any ideas or hints to documentation of securing the password transfer process? Raphael

Changing path of the cataloged objects
by Igor Leturia 16 Jan '03

16 Jan '03

Hi all, I have some objects external to the ZODB that I have cataloged in a ZCatalog. The objects have been moved to another directory, so I need to change the path of the cataloged objects. For various reasons (not the weakest of them being the long time needed to catalog all these objects) I would like to do this without having to recatalog all. What would be the python code to achieve this? Thanks in advance, Igor Leturia

Yes! Well, almost: it had to be <dtml-call "REQUEST['my_langs'].append(langShort)"> etc for some reason... To anyone who got confused, of course, I was using Beno's example which was representative of something I needed.. Using append as a counter was new to me, thanks for that! Ken

data manager object - seeking comments
by Dylan Reinhardt 16 Jan '03

16 Jan '03

Howdy Zopers, The last year or so, I've been making extensive use of a drop-in data manager class in my products. It started off as a caching database connector and at some point I decided it was a better tool without the database layer. :-) It was designed to simplify the process of storing, optimizing, and extracting complex (i.e. "Pythonish") data so that it isn't necessary to translate back and forth between OO-style data and SQL-style data. It's basically a big mapping with recordset caching, selection/aggregation mechanisms, data typing and multi-level sorting built in. I wouldn't say it's optimal for *all* kinds of data, but it sure seems to work well at organizing the kind of data you might kick up in a mid-size business app. My last several apps don't have a scratch of SQL in them anywhere. :-) Anyway, it's my baby so I've lost perspective on it and don't really have any idea whether this is a redundant and/or stupid idea or if this is the kind of thing I should be releasing to the community. Some comments and perspective on this would be greatly appreciated. Please respond directly & I'll update the list with whether or not I'll be making a release announcement. Thanks in advance for any (seriously, any) feedback, Dylan
