Usage:

class SomeForm(forms.Form):
    emails = MultipleEmailsField()

diverman (on April 26, 2009):

Do you store multiple emails in one database column?

#

spanasik (on April 28, 2009):

No, it's required for user input, when multiple emails can be entered into one form field.

#

spanasik (on April 28, 2009):

It seems like there is a better solution in the Django documentation: http://docs.djangoproject.com/en/dev/ref/forms/validation/ (MultiEmailField)

#

andybak (on May 28, 2009):

spanasik - the solution in the docs is identical but is missing the email_re here

#

asinox (on May 13, 2012):

Remember that email_re has moved from django.form.fields to django.core.validators
