在Django机型中存储电话号码的最佳方式是什么？ [英] What's the best way to store Phone number in Django models
问题描述
我正在以模式存储电话号码：
phone_number = models.CharField(max_length=12)
用户将输入一个电话号码，我会使用 SMS Authentication 的电话号码此应用程序将在全球使用。所以我也需要国家代码。是 CharField 是存储电话号码的好方法吗？而且，如何验证电话号码？
User would enter a phone number and I would use the phone number for SMS Authentication This application would be used globally. So I would also need country code. Is CharField is a good way to store phone number? And, how do I validate phone number?
提前感谢
推荐答案
标准格式 E.164 ， Twilio推荐的例子（谁有服务以及用于通过REST请求发送短信或电话呼叫的API）。
You might actually look into the internationally standardized format E.164, recommended by Twilio for example (who have a service and an API for sending SMS or phone-calls via REST requests).
这可能是存储电话号码的最普遍的方式，特别是如果您有国际电话号码。
This is likely to be the most universal way to store phone numbers, in particular if you have international numbers work with.
您的模型的一个注释：E.164号码的最大字符长度为15。
One note for your model: E.164 numbers have a max character length of 15.
要验证，您可以使用格式化，然后尝试请立即联系以验证。
To validate, you can employ some combination of formatting and then attempting to contact the number immediately to verify.
我相信在我的django项目中使用了以下内容：
I believe I used something like the following on my django project:
class ReceiverForm(forms.ModelForm):
phone_number = forms.RegexField(regex=r'^\+?1?\d{9,15}$',
error_message = ("Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed."))

看来，对一些人来说是有用的，似乎值得将下面的评论整合成一个更加完整的答案。根据 jpotter6 ，您也可以在模型上执行以下操作：
It appears that this post has been useful to some folks, and it seems worth it to integrate the comment below into a more full-fledged answer. As per jpotter6, you can do something like the following on your models as well:
models.py：
models.py:
from django.core.validators import RegexValidator
class PhoneModel(models.Model):
...
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
phone_number = models.CharField(validators=[phone_regex], blank=True) # validators should be a list
