Thanks Chris and Jorge,
It turns out that after using the magic of widgets and forms, I had
forgotten about validators (whoops). Jorge, I was able replace my
previous controller method with the following:
class MySchema(validators.Schema):
field1 = validators.String(not_empty=True)
checkedBoxes= validators.JSONValidator(not_empty=True)
...
# in RootController:
@expose(format="json")
@validate(validators=MySchema())
def doSomething(self, field1, checkedBoxes):
log.info("Request Headers: \n%s" %request.headers)
# I didn't feel like writing my own validator, so I still have
to convert
# the list elements to from strings to ints
intList = map(int, checkedBoxes)
return dict(results=foo(field1, intList))
Chris, formContents is a neat function, but I couldn't get it to work
for my application. The problem is that, when using the CheckBoxList
widget (http://trac.turbogears.org/browser/branches/1.0/turbogears/
widgets/forms.py#L1053), all the checkboxes have the same name.
Additionally, there seems to be an extra field included in the output
(HTML) which I, as a user of the CheckBoxList widget, seem unable to
easily disable. Here's the query string I get from running:
arr = formContents(); queryString(arr[0], arr[1]);
HTML=&field1=foo&checkedBox=0&checkedBox=1&checkedBox=2&checkedBox=4&checkedBox=9&checkedBox=11&checkedBox=13&checkedBox=17&checkedBox=18&checkedBox=24&checkedBox=25&checkedBox=29&checkedBox=36&checkedBox=41&checkedBox=42&checkedBox=45&checkedBox=46&checkedBox=51&checkedBox=53&checkedBox=54&checkedBox=55&checkedBox=58
In the end, I'm sticking with my original javascript which manually
selects the checked boxes with the document.form.checkboxElements
command (see loadMatches() above).
Thanks to you both for responding so quickly and being so helpful!
