[Zope] tal:attributes question

2005-07-22 Thread Erik Myllymaki 

I am trying to set the bgcolor of a page based on the existance of a variable.

Neither of these seem to work:

body
  tal:attributes=bgcolor python:test(hasattr(options, 'error'), 'red', 
'green')

body
  tal:attributes=bgcolor python:test(hasattr(request, 'error'), 'red', 
'green')

I can access the error variable with this:

p class=error tal:condition=exists: options/error 
tal:content=options/error | nothingThere was an error/p

Try this:

body
   tal:attributes=bgcolor python:test(options.has_key('error'),
'red', 'green')
