Question

我正在尝试创建一个电话号码字段，遵循Django官方文档，但得到以下异常，我理解这是因为CharField并希望将其转换为整数。但我真的需要将它转换为整数或字符串，我无法将其转换为。我想要<Country code>-<Phone Number>X<Extn>格式的电话号码。

以下是代码：

from django import forms
from django.core.validators import RegexValidator
from django.db import models

class PhoneWidget(forms.MultiWidget):
    '''
    Custom Form widget to display/input international phone numbers
    '''
    def __init__(self, *args, **kwargs): # pylint: disable=E1002
        widgets = (
            forms.RegexField(r'^[1-9]\d*', min_length=1, max_length=4),
            forms.RegexField(r'^[1-9]\d*', min_length=7, max_length=10),
            forms.RegexField(r'^\d+', min_length=0, max_length=5, required=False),
        )
        super(PhoneWidget, self).__init__(widgets, *args, **kwargs)

    def decompress(self, value):
        if value:
            split_x = value[1:].split('x')
            split_nos = split_x.strip().split('-')
            return [split_nos[0], split_nos[1], split_x[1].strip()]
        return ['', '', '']


class PhoneField(forms.MultiValueField):
    '''
    Custom field to keep international phone numbers
    '''
    def __init__(self, *args, **kwargs):
        # Define one message for all fields.
        error_messages = {
            'incomplete': 'Enter a country code and phone number.',
        }
        # Or define a different message for each field.
        fields = (
            models.CharField(error_messages={'incomplete': 'Enter a country code.'},
                             validators=[RegexValidator(r'^[1-9]\d{3}$',
                                                    'Enter a valid country code (without leading Zeros).')]),
            models.CharField(error_messages={'incomplete': 'Enter a phone number.'},
                         validators=[RegexValidator(r'^[1-9]\d{9}$',
                                                    'Enter a valid phone number (without leading Zeros).')]),
            models.CharField(validators=[RegexValidator(r'^\d+$', 'Enter a valid extension.')],
                         null=True),
        )
        super(PhoneField, self).__init__(
            self, error_messages=error_messages, fields=self.compress(fields),
            require_all_fields=False, *args, **kwargs)
        self.widget = PhoneWidget

    def compress(self, data_list):
        if data_list[2] != None and data_list[2] != '':
            return '+%d-%d x %d' % (int(str(data_list[0])), int(str(data_list[1])), int(str(data_list[2])))
        else:
            return '+%d-%d' % (data_list[0], data_list[1])

但是得到这个例外：

Request Method: GET
Request URL:    http://127.0.0.1:8000/
Django Version: 1.6
Exception Type: ValueError
Exception Value:    
invalid literal for int() with base 10: '<django.db.models.fields.CharField>'

在压缩方法中，我是类型转换。感谢是否有人可以在这方面帮助我。

注意：我知道有一个可用于国际电话号码的开源库，可以稍微改写以解决我的目的，但我想自己做。
