Using a Session variable in a dtml-var
by Paul Zwarts 22 Jan '01

22 Jan '01

Hi all, Im trying to call a variable from SQLSession and then use it in a var. I am using SQLSession to store the 'zone' value which I want to call in the index_html document to then include a specific dtml-method depending on the variable that the Session returns. SESSION['zone'] will equal 'Home', so I want to: <dtml-var Home>, where 'Home' is a dtml-method that contains html and dtml that is specific to the page I want called. so I've tried: <dtml-var name="SESSION['zone']"> <dtml-var "PARENTS[-1].BC2.SESSION['zone']"> ...But I cant seem to get it to work and I've spent hours searching the zope site.... I'm also trying to do the same thing with other methods that contain interface html and all are name by A_<name> B_<name> called from SESSION['interface'] so I wanted to do something like: <dtml-var name="'A_'+SESSION['interface']"> Which of course doesnt work either.... Can anyone help? Thanks very much in advance..... Paz

RE: [Zope] Tools used for programming Zope

At 02:37 PM 1/18/2001 -0600, you wrote: >do an xml export. You can save cvs that to your hearts content. ... but then I'll have to forego readability, edit-ability, etc. Frankly, I'm a little surprised that this isn't a problem for more people, given the drawbacks of having to give up many of the existing tools, having the application server only be able to export in a proprietary format, and being bound to the application server for so many development-related tasks. It's impossible to do a simple grep through the code, for example ... I'm trying to reconcile this, as you might see, because I want to use Zope but am having a hard time making it work for me.

FW: MS-SQL Server Connector

Hi Adrian > I tried this about 6 months ago. It seems that Micro$oft > changed that protocol that SQL7.0 uses, just enough to prevent > Sybase connectors from working. (I probably should have > mentioned 7.0 in the message... sorry) Ouch! There are some other options, a few of which I've tried, mostly some variation on ODBC, many of them listed here, (some even with links): http://www.zope.org/Members/mcdonc/RelationalDatabaseWiki/ODbC There is a quasi-mythical ODBC DA for Linux that I have yet to successfully implement, but you can find some hints here : http://www.zope.org/Members/jrush/news_ZODBCDA_solid_linux Good luck!, Jerry S.

Alternating Row Colors
by Darin Lee 22 Jan '01

22 Jan '01

Lee, Alternating row colors are very easy in Zope because of the variables 'sequence-odd' and 'sequence-even' defined by the <dtml-in> tag. A super quick example: <table bgcolor="#ffffff"> <dtml-in some_list> <tr <dtml-if sequence-odd>bgcolor="#EEEEEE"</dtml-if>> <td>Your cell data here</td> </tr> </table> You can code variations on this to get what you need. -Darin

Adding roles in 2.3b2 and CVS
by Phil Harris 22 Jan '01

22 Jan '01

All, Has anyone else had trouble adding roles when using 2.3b2 and CVS versions of Zope? There seems to be a consistent bug in <ZopeDIR>/lib/python/AccessControl/role.py. The calls to self.manage_access(self,REQUEST) seem to have too many arguments, am I right? I 'fixed' my version of the file ut someone with more nouse will need to check this out. Would this be better reported in the collector? Phil phil.harris(a)zope.co.uk

form question
by Oliver Vecernik 22 Jan '01

22 Jan '01

Hi all, I'm a newbie to Zope and Python. Nevertheless I'd like to start with it. I'm designing an application gathering data with forms. Navigation should be done with Prev and Next buttons. As long as I'm not leaving the form data should be entered, processed and the *same* or another form should be displayed, depending on input of the user. So far I'm able to gather data, store them in a database, but can anybody give me a clue or point me to some docs how to control which form should be displayed next? It should depend on users input of let's say a text field. Oliver
