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 | nothing">There was an error</p>
