evaluation within <dtml-sendmail>-tag
by Stefan Doerig 22 Sep '00

22 Sep '00

hello i had to create a html form where the user can enter his email address and select over a few check boxes several pdf-files which then get attached to an email and finally sent to the users address. 1. the problem is a <dtml-if> or a <dtml-in> tag within the <dtml-sendmail> tag causes an error and so it does not seem possible to me to evaluate the users input in dtml only. but i have to evaluate because there are up to twelve files to select. 2. so i wrote an external method which does the job. it works and creates an fine email with the selected files attached. the only problem that the pdf files are presented on the web site as well and therefor integrated in zope and the external method i wrote reads them from the file system because i could not access the file data in zope from the external method. so i have the pdfs twice once on the file system and once in zope. so, is it possible to access data which are actually in zope through an external method? is there an easier way around this? have a nice time -- stef

Close your eyes . . .

and pretend that Zope can do this today! http://standardbrains.editthispage.com/ This is where we're headed with DAV, XML / DOM, Zope Studio, etc. Sorry the demo only works (today) with MS IE v. 5+. If you can get to a desktop with this installed, it is such a trip to swipe some content, and edit in place, without a #%&@ text box! So this is what Tim Berners Lee had in mind with that funny little put method . . . Later, Jerry S.

Data date type returned by ZSQL method
by Stuart Foster 22 Sep '00

22 Sep '00

I am trying to format a date value that is returned by a ZSQL method but keep getting an error. I am using the same format string where I use ZopeTime <dtml-var ZopeTime fmt="%m/%d/%Y">. Yet when I try to use it for a timestamp field from PSQL I get the following error. Error Type: ValueError Error Value: unsupported format character 'm' (0x6d) It sounds like the value being returned isn't a true date type? Any clues?

GUF strange behavior
by Cesar A. K. Grossmann 22 Sep '00

22 Sep '00

Hi! I have discovered that I was fighting the wrong fight, against GUF. After making a login, I get the old, good, login page again. If I reload the page, then I get the correct index_html page, instead of the login page. What is wrong with this? I put the "pragma" "no-cache" in a META tag in the header of the docLogin method, but I still needs a reload to get the right page, instead of the login page. Is it a Netscape bug? Is it a GUF bug? Is it my mistake? I'm using Zope 2.1.6, GUF 1-2-4 in a Linux 2.2.x box. TIA -- César A. K.

Re: [Zope] JDBC DA from Python

I bet it would be easier than you think. There are at least 2 python DB API compliant interfaces to JDBC that I know of. So you should be able to write a generic python/jpython server that talks to a DB API and returns the results to the client. This is similar to how sqlrelay works. I think you should even be able to send pickles of the data retults over the socket - because as far as I know jpython and python use the same pickle code. I would bet that it is gonna be god awful slow. Might be good enough for small return sets though. ^Roman

Check if Image is uploaded solution
by peter bengtsson 21 Sep '00

21 Sep '00

I'll post this on Zope Tips. I've struggled with this for almost an hour soon, and since no good answer was provided in the mailinglist or the weblogs, I post it. ----- How to check if an Image has been uploaded from a file form or not. <precondition> <input type=file name=myimage> </precondition> <dtml-if "_.len(_.getattr(myimage,'filename')) > 0"> Image posted <dtml-else> No image posted </dtml-if> ----- Reflections on this? -- / Peter

nitpick
by Andy McKay 21 Sep '00

21 Sep '00

Why does an objects url have spaces in it? eg: /foo / bar / article.... If you ever copy and paste this, you then have to delete the spaces. Am I the only one who finds this annoying. Hack coming up :) -- Andy McKay, Developer. ActiveState.

JDBC DA from Python
by Brian.Burton＠nlynx.com 21 Sep '00

21 Sep '00

Has anyone come up with a way to access a JDBC driver from Zope? I have since several JPython solutions but I don't see a way of executing JPython from Zope. Would the best way be to write a Zope/Python DA that opens sockets to a JPython or Java servlet that then talks to the JDBC driver? Sounds like a bit of work. Brian

Assigning Permissions To Roles
by Kevin Howe 21 Sep '00

21 Sep '00

I am having trouble getting Roles to work via my Python Product. Creating a local role works fine: self._addRole('myRole') But how do I tell the Role what permissions it has programmatically? After looking in Role.py, I tried the following: self.manage_role('myRole', ['View management screens, View']) but this kicks up an error. Am I calling this impoperly? kh
