Out of the box, Django e-mail fields for both database models and forms only accept plain e-mail addresses. For example, [email protected] is accepted.
On the other hand, full e-mail addresses which include a human-readable name, for example the following address fails validation in Django:
Joe Hacker <[email protected]>
This package adds support for validating full e-mail addresses.
Database model example
from django import models
from full_email.models import FullEmailField
class MyModel(models.Model):
email = FullEmailField()
Forms example
from django import forms
from full_email.formfields import FullEmailField
class MyForm(forms.Form):
email = FullEmailField(label='E-mail address')
I maintain this code in a GitHub gist. It includes some unit tests as well.
