request.GET.getlist('root') will get you back a list of all of the
root= values.
This is one of my favourite features of Django's request handling.
PHP only ever gives you back the last value (unless you use root[]
=blah&root[]=blah2 which is a bit weird). Python's cgi module ALWAYS
gives you back a list, even though 99% of the time you only want one
value. With Django, we decided to make the common case (a single
value) act like a dictionary, but provided an explicit mechanism for
accessing lists of values. You can rely on the fact that request.GET
[key] will only ever return a single string, while request.GET.getlist
(key) will always return a list of strings (or an empty list).
