[Zope] Python Methods can't construct literal dictionaries?
I'm trying to create a Python Method, using PythonMethod 0-1-7, that
validates a set of form values before updating a database. I planned
to return any/all errors as a dictionary keyed by the errant field
name. But statements like this in my Python Method
input_errors = {}
input_errors['password'] = "password must not be empty"
...
return input_errors
result in the following error when I try to save the change to the code:
Error Type: Python Method Error
Error Value: Forbidden operation STORE_SUBSCR at line 3
What's up with that? I can't create dictionaries in Python Methods?
I must be missing something. Is there some way around this?

Re: [Zope] Python Methods can't construct literal dictionaries?
This is one of the shortcomings of Python Methods that Scripts eliminate.
You can work around it by writing:
x = {}
x.update({y: z})

Is there any way you can see what the results are looking like without having to vote again? Don't worry, there's no need actually to count the votes. Despite the fact that this race went right down to the wire, according to my complex computer-based prediction models (based on exit polls and incredibly detailed statistical analysis) I can hereby announce that "Python Script" is the outright undisputed winner :) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Python Methods Vote
I have the opposite problem. Having voted once - early yesterday - I now can't vote again. The reason I want to vote again is that I have changed my mind! Now I want to _poll down_ "Python Method" and add a new alternative "ZPython Method" or add some points to "Python Script" or "ZPY". The poll is not cookiebased.

[Zope] Python Methods 0.1.7 under Zope 2.2.1
Working with Zope 2.2.1 (in two distinct servers), I noticed the following behaviour with (0.1.7) Python methods (created under Manager role): 1. Apparently anyone (non-authenticated users) can successfully run the methods even if these include operations (folder/file/user creation, etc.) for which the invoking user has no permission. 2. Although I am able to give Python methods the proxy role of Manager, I can not give them other proxy roles, roles which I also have and am able to give to DTML methods, for instance (anyway, problem 1 makes privileged proxy roles superfluous... :) ). Has anyone fixed this (while we wait for the new shiny Python methods)?
