在wtfforms驗證美國電話號碼

Question

我用的燒瓶中的應用工作，並使用wtforms我：

class RegisterForm(Form): 
    username = StringField('Username', validators=[DataRequired(), Length(min=3, max=25)]) 
    email = StringField('Email', validators=[DataRequired(), Email(), Length(min=6, max=40)]) 
    phone = StringField('Phone', validators=[DataRequired(), Length(10)]) 

我剛加入手機和正在尋找一種方法來驗證一個美國號碼。我遇到了http://wtforms-components.readthedocs.org/en/stable/#phonenumberfield，但這似乎不再有phonenumberfield。什麼是最好的方式來處理這與wtfforms？

編輯類：

class RegisterForm(Form): 
    username = StringField('Username', validators=[DataRequired(), Length(min=3, max=25)]) 
    email = StringField('Email', validators=[DataRequired(), Email(), Length(min=6, max=40)]) 
    phone = StringField('Phone', validators=[DataRequired(),validate_phone('RegisterForm','phone'), Length(min=6, max=40)]) 

    def validate_phone(form, field): 
     if len(field.data) > 16: 
      raise ValidationError('Invalid phone number.') 
     try: 
      input_number = phonenumbers.parse(field.data) 
      if not (phonenumbers.is_valid_number(input_number)): 
       raise ValidationError('Invalid phone number.') 
     except: 
      input_number = phonenumbers.parse("+1"+field.data) 
      if not (phonenumbers.is_valid_number(input_number)): 
       raise ValidationError('Invalid phone number.')

我在最近的應用程序利用了python-phonenumbers。它使用谷歌手機號碼解析的東西。以下是我如何使用它：

from wtforms import ValidationError 
import phonenumbers 

class RegisterForm(Form): 
    username = StringField('Username', validators=[DataRequired(), Length(min=3, max=25)]) 
    email = StringField('Email', validators=[DataRequired(), Email(), Length(min=6, max=40)]) 
    phone = StringField('Phone', validators=[DataRequired()]) 

    def validate_phone(form, field): 
     if len(field.data) > 16: 
      raise ValidationError('Invalid phone number.') 
     try: 
      input_number = phonenumbers.parse(field.data) 
      if not (phonenumbers.is_valid_number(input_number)): 
       raise ValidationError('Invalid phone number.') 
     except: 
      input_number = phonenumbers.parse("+1"+field.data) 
      if not (phonenumbers.is_valid_number(input_number)): 
       raise ValidationError('Invalid phone number.')
