Hi, (As you know) I'm a zope newbie. I didn't find a article describing my following problem. I can not import python objects like 'time'. If I use import time I'll become the error message You are not allowed to access 'time' in this context Is it not possible to do this???? Thank you very much Ferhat __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

iterating dictionaries with dtml-in
by Ferhat Ayaz 03 Sep '06

Hi, I know it's a silly question. But I was not able to find an example for this: I have a list of dicts like [ {'name':'John','age':27}, {'name':'Marc','age':17}, {'name':'Susanne','age':19} ] Now I want to iterate each 'name' like <select> <option>John</option> <option>Marc</option> <option>Susanne</option> </select> I want to do this with DTML. <select> <dtml-in getDicts> <option> HOW CAN I PUT the keys 'name' HERE ???? </option> </dtml-in> </select> (getDicts returns the above list of dictionaries) Thanks and greets, Ferhat __________________________________________________ Do You Yahoo!?

ZEO Problem
by beno 02 Sep '06

02 Sep '06

Hi; I'm reading the Plone book. It states that for Zope 2.7 (I have 2.78) ZEO is built in by default but must be instantiated thus: cd /opt/Zope-2/7/bin ./mkzeoinstance /var/zeo or some such code. So I tried this: cd /usr/local/zope/278/bin ./mkzeoinstance.py ../../instance2/var/zeo where 278 is my installation, instance2 is a Zope instance (I have 3), and mkzeoinstance.py is the command that works (mkzeoinstance by itself doesn't print anything to screen other than a command failed message). The Plone book then states that I must move Data.fs into the new /zeo/var dir, which I did. Everything seems to go well. If I start Zope using runzope I get this output at the tail end: ------ 2006-09-02T13:15:35 INFO(0) Zope Ready to handle requests However, if I try to log into the ZMI my passwords don't work. I even tried creating an emergencyuser and that didn't work, either. What to do? Also, should I move these other files into the new zeo/var dir? Data.fs.index Data.fs.lock Data.fs.old Data.fs.tmp I tried that, also, with negative results, but it seems to me that if I'm moving Data.fs I should move these others as well. TIA, beno

As an experiment, can you try running zeoctl as the root user? If this works, then it is definitely a problem with the permissions that your 'zope' user has (the error you described is normally a permissions related error). Jonathan

Parameter generating an exception?
by Tit-Liviu Leontin 01 Sep '06

01 Sep '06

Hi everyone, I'm using Zope with OpenFlow for a workflow. The problem I'm encountering now seems to be entirely related to Zope; actually, a particular value for a parameter generates the error, so I'm guessing there's something wrong with the data, not the script. There's a "browse" file defined in the workflow, with the following first lines: <html><body> <html> <body tal:define="results here/Catalog; qq request/QUERY_STRING; qs python:container.stripStart(qq); start request/start|python:0; batch python:modules['ZTUtils'].Batch(results, size=20, start=start); previous python:batch.previous; next python:batch.next"> Now, if I call this script with no parameters in the URL, it shows all documents. If I append a ?issuer=john.d parameter to the URL, only documents issued by john.d will be displayed. This works even for fictive names, displaying a blank table as a result. However, for a particular user (and only that one), I'm getting this error: Error Type: TALESError Error Value: exceptions.KeyError on -1882874846 in "<PythonExpr modules['ZTUtils'].Batch(results, size=20, start=start)>", at line 3, column 3 In the page source, this is the detailed debug information:  Unfortunately, all this is worse than Chinese to me. Any clue where the error may be, and what to do to fix it, please? Many thanks in advance! Titel
