How do you call a shell command from an external method
by Friedlander Paul 25 Sep '02

25 Sep '02

I have been trying to get Ploticus to work from an external method with no luck. I put the file (pl.exe) in the Extensions directory for the quick test and used the following code" import os def test(self): result = os.system("c:\\Progra~1\\WebSite\\Extensions\\pl gantt.pl -gif -o test.gif") return result If I run the command from the prompt it works great. When I call this function from Zope I get a return value of 1 and no file is created. I have tried numerous variations on the path with no luck. Does anyone know how I can shell out to the program?

Getting access to additional-passed in variables from dtml
by VanL 25 Sep '02

25 Sep '02

Hello, I want to use dtml as a variable-substitution engine. However, I'm not sure how to see what variables I have available. For example, with page templates I can do the following: <span tal:repeat="key python:options.keys()"> <span tal:replace="key">The Key</span> </span> Is there an equivalent structure in dtml? Thanks, VanL

<dtml-in>
by Székely Csaba 25 Sep '02

25 Sep '02

Hi there, I'm new in Zope, and I have some problems. The first: <dtml-var standard_html_header> <dtml-in expr="select_sql(qry_table='localitate', qry_fields='locID, localitate')"> <dtml-if expr="locid == locid_form"> <h3><dtml-var locid></h3><br><dtml-var locid_form><br><br> <dtml-else> <dtml-var locid><br><dtml-var locid_form><br><br> </dtml-if> </dtml-in> I get the <dtml-var locid_form> from a DTML Document. The goal is to highlight one line from the list. The second is related to the 1'st one : I have this select list: <select name=tipos size="3"> <dtml-in expr="select_sql(qry_table='tipOS', qry_fields='tipOS, descriere')"> <option value="&dtml-tipos;"><dtml-var descriere> </dtml-in> </select> I'd like to have a default selection, based on a input parameter. I fugured that it will be something like this: <select name=locid> <dtml-in expr="select_sql(qry_table='localitate', qry_fields='locID, localitate')"> <dtml-if expr="locid == locid_form" <option value="&dtml-locid;" selected><dtml-var localitate> <dtml-else> <option value="&dtml-locid;"><dtml-var localitate> </dtml-if> </dtml-in> </select> but it's not working, like I thought it would. So I need some help wit this, I allready RTFM, for a couple of time. Thanx. Bubu

Hi, below an issue I don't have any idea where the problem lies. Are there some experts around that could give me some advice? Thanks! The code is for the redesign of the swiss community site http://www.zope.ch hopefully working in two weeks. So please, help!

Hello, I just installed ZSyncer and ran into a problem. I verfied that ZSyncer is working by syncing two local zope servers. But when I try to connect to my production server I will get a "(111, 'Connection refused')" error. My development boy is inside a private network with a NAT firewall to the outer world.

manage_beforeDelete
by Júlio Silva 25 Sep '02

25 Sep '02

When I rename one object (one instance of a zclass) the object actualy is deleted and then created, which makes the trigger manage_beforeDelete to be called on the delete operation. the problem is I dont want to call manage_beforeDelete when renaming this object. Is there a way to test in manage_beforeDelete (defined in my zclass) If the ZMI operation is a rename or a delete? -- Julio Silva --- Outgoing mail is certified Virus Free.
