it might be better to ask this on a django forum since it sounds
like you want django's orm to handle this. you probably just
need to subclass PhoneNumberField so its constructor will
reformat whatever is given to it as the phone number to be
inserted. maybe you need a Manager class for the model (probably
not). maybe you just need a function that takes the default
country code or country dialling code and the phone number and
returns what you want to insert and then always use its return
value when assigning a value to the phone_number field. i
suspect that subclassing PhoneNumberField is probably the best
approach.
