This is a custom field for multiple emails separated by comma. Original code was replaced by code from Django documentation: http://docs.djangoproject.com/en/dev/ref/forms/validation/ (MultiEmailField) so i'm not the author of the code, but just put it here to replace an outdated solution.

Uses code from mksoft comment http://www.djangosnippets.org/snippets/1093/

        Check that the field contains one or more comma-separated emails
        and normalizes the data to a list of the email strings.

        # Always return the cleaned data.
        return emails

<p>Usage:</p> <pre>class SomeForm(forms.Form): emails = MultipleEmailsField() </pre>

<p>Do you store multiple emails in one database column?</p>

#

spanasik (on April 28, 2009):
<p>No, it's required for user input, when multiple emails can be entered into one form field.</p>

<p>spanasik - the solution in the docs is identical but is missing the email_re here</p>

<p>Remember that email_re has moved from django.form.fields to django.core.validators</p>
