ajax - The right way to send some data alongside with form -

i have page of user oders, displayed products in cart , form fields like: address, mobile number etc. catch submit jquery, , need send next data server: form , dictionary {id_of_product:choosen_ammount}. need send dictionary, because check whether there such ammount of product user choose. if not, send error. use ajax. send data looks:

data = {             form : $(this).serialize(),             products: somedict         }  

in django next:

from urlparse import parse_qs form = parse_qs(request.post['form'])     if request.post:         order_form = orderform(data=form) 

but faced problem: saves not correct data database. example saves text string like:[u'\xd0\x9a\xd0\xb8\xd1\x97\xd0\xb2'] . tried check returns order_form.cleaned_data['address_city'], returns same. so, how solve problem?

use django's querydict.

from django.http import querydict   # encode form data byte string. form_data = querydict(request.post['form'].encode('ascii')) order_form = orderform(data=form_data) 

note: first part of problem: pass json , deserialize form in django
