sqlite - django and bank transfer system javascript injection using chrome extension -

for academic course of cryptography , security, have create basic system bank transfers.

i decided use django, gives me authentication , database without effort.

the task create chrome extension change receiver bank account number send server, user see 1 provided in transfers history. both, server , user, should think correct when have different numbers.

my concern how approach this. when database (default sqlite3) created , edited using django (hence python) how fiddle using javascript in chrome extension.

my database model:

class transfer(models.model):     user = models.foreignkey(settings.auth_user_model, editable=false)     acc_num_from = models.charfield('from account number', max_length=28)     amount = moneyfield('transfer amount', max_digits=12, decimal_places=2, default_currency='pln')     acc_num_to = models.charfield('to account number', max_length=28)     rec_name = models.charfield('receiver name', max_length=120)     rec_street = models.charfield('street', max_length=64)     rec_pcode = models.charfield('postcode', max_length=6)     rec_city = models.charfield('city', max_length=32)     title = models.textfield('title', max_length=140)     post_time = models.datetimefield('transfer date', auto_now=false, auto_now_add=true) 

should fiddle form? there again problem, generated template in django.

any useful, 1st contact django server , breaking wrote work.
