Allow different region validation in DRF SerializerField from PHONENUMBER_DEFAULT_REGION

[jrbenriquez]

Hi

Currently in our app we don't use Django Forms, all data goes through serializers and so basing from
The solution provided here

Is it possible to declare the fields for a specific region validation?

i.e. something like:

class ASerializer(ModelSerializer):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        fields = getattr(self, "_fields", None)
        try:
            instance = args[0]
        except IndexError:
            instance = None
        if not instance:
           return
        if not hasattr(instance, 'get_country', None):
            return
        country = instance.get_country
        self._fields[field_name] = PhoneNumberField(region=country)

I am trying this approach but currently getting

 File "xxx", line 274, in __init__
    self._fields[field_name] = PhoneNumberField(region=country)
  File "xxx/.pyenv/versions/3.6.11/envs/brokerengine/lib/python3.6/site-packages/rest_framework/fields.py", line 754, in __init__
    super(CharField, self).__init__(**kwargs)
TypeError: __init__() got an unexpected keyword argument 'region'

Looks like custom regions in DRF serializers are not supported yet? (I may have to write additonal code for that)
By doing this will I be able to override the normal validation that happens for the default region?

Any idea if this has been resolved?
