fast_tz_detector returns a SCRIPT().
Of course you can't "read it" because the page executes it, so it's fine if
you see a blank space:
If you see the page source (using firefox, right click --> View page
source) you'd see a <script>blablablabla</script>
On the "let's save it to the database" topic ..... try it yourself:
def index():
print 'Hi, you should save this ', request.vars
some_message = "here timezone is detected"
tz = fast_tz_detector()
return ....
When you return a "fast_tz_detector()", as soon as the browser loads the
page, javascript detects the timezone and it is sent back to the same
controller function (in this case, "index").
Another way is to "hack it up" somewhere
def index():
if session.plugin_timezone_tz:
db.sometable.insert(
detected_timezone=session.plugin_timezone_tz, user_id=auth.user_id)
some_message = "here timezone is detected"
tz = fast_tz_detector()
return .....
