You would normally do this by overriding __init__

from django.forms import ModelForm, ChoiceField
class MyModelForm(ModelForm):
    class Meta:
        model = MyModel

    def __init__(self, *args, **kwargs):
        super(MyModelForm, self).__init__(*args, **kwargs)
        geoiplocator_instance = GeoIpLocator()
        city_country_dictionary=geoiplocator_instance.get_country_city_dictionary()
        users_country_name = city_country_dictionary['country_name']
        users_city = city_country_dictionary['city']

        # not exactly sure what you wanted to do with this choice field.
        # make the country the only option? Pull a list of related countries?
        # add it and make it the default selected?
        self.fields['country'] = ChoiceField(choices = [(users_country_name, users_country_name),])
        self.fields['city'].initial = users_city

You can wrap the form class inside a function, and then in your view just call this function.

def make_user_reported_data_form(users_city, users_country_name):
    class UserReportedDataForm(djangoforms.ModelForm):

        class Meta:
            #mechanism to get the users country and city
            geoiplocator_instance = GeoIpLocator()
            city_country_dictionary=geoiplocator_instance.get_country_city_dictionary()
            users_country_name = city_country_dictionary['country_name']
            users_city = users_city
            model = UserReportedData(default={'country':users_country_name})
    return UserReportedDataForm
