I looked into this some more. If you set "target", then in fact you have
no way to make a case distinction for errors, the result is always put
into the target element. But if instead of "target", you can set
"dataType" to e.g. "json" and "success" to a js_callback function, .e.g
my_ajax_form = ActiveForm(id="myAjaxForm",
action="do_search", fields=CommentFields(),
dataType = 'json', success = js_callback(
"function (data) $('#' + data.target).html(data.output)"))
Now you could implement the controller like this:
@expose('json')
@validate(my_ajax_form)
def do_search(self, **kw):
if tmpl_context.form_errors:
target = 'my_ajax_form'
output = re.sub('<form [^>]*>|</form>', '',
Markup(my_ajax_form(kw)))
else:
target = 'output'
output = '<p>Received data: %s</p>' % kw
return dict(target=target,output=output)
In case of a validation error, this will redisplay the form with the
error messages, otherwise show the result.
I also noticed that besides tw.jquery.AjaxForm, there is a
twAjaxTools.AjaxTableForm widget which seems to include some support for
validation as well as flash and redirect. Maybe we should add
documentation for that as well? Strangely, the ajax_form.js file from
that package is also in tw.jquery. I wonder how it got there because it
has nothing to with jquery and is not used by tw.jquery at all?
