python - django-phonenumber-field: get phone number field validation pattern -

i using django-phonenumber-field in model. parsley.js validate model form on client side. however, cannot find regular expression used validate phonenumberfield field on server side.

i use exact same expression if possible.

here model , form:

from phonenumber_field.modelfields import phonenumberfield  @python_2_unicode_compatible class cvapplication(application):     mobile_phone_number = phonenumberfield()     [...]   @parsleyfy class cvapplicationform(forms.modelform):     class meta:         model = cvapplication         fields = (             'mobile_phone_number',             [...]         )      def __init__(self, *args, **kwargs):         super(cvapplicationform, self).__init__(*args, **kwargs)         self.fields['mobile_phone_number'].widget.attrs.update(             {'data-parsley-pattern': '??????????'}         )         [...]
