Hi there,
I have run into similar issues in the past. I have come up with two
solutions:
1) The standard way to provide preselected values to any widget at
request time is to pass in a values dictions in the template, such as:
${form.display(dict(select_field: [1, 2, 3]))}
I'm not sure of the exact syntax, but it is along those lines. With
that, you could pass in a dict of values calculated in the controller
and passed to the template.
2) The other way is to set values in cherrypy.request in teh
controller method and then retrieve them in the myCallable default.
For example:
def myCallable():
return cherrypy.request.bar.pets
class Foo(Controller):
def method(self, id):
bar = model.get(id)
cherrypy.request.bar = bar
You can actually use both these idioms in many situations, but
SelectLists are a common use of them.
Anyway, I hope this helps. My code examples may not be perfectly
accurate (going from memory), but I think you'll get the idea.
Good luck,
Krys
