How to make email field optional in django.contrib.comments

Published at 02, June 2009, author art. Tags: django, python, snippet, tips

Today I solved a little problem on my personal blog http://svetlyak.ru. I'm using the django.contrib.comments there, and some my readers encounter a problem. They are registered using OpenID, but don't have a email in their accounts, because OpenID provider does not share that information.

So, when such users tried to post a comment on my blog, they are shown a page with error, because email is required field.

I found a simple way to make an email field optional. All what you need is to add additional app in the INSTALLED_APPS, and COMMENTS_APP variable. In my case it's looks like that:

INSTALLED_APPS = (
    'django.contrib.sessions',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sites',
    'django.contrib.admin',
    'django.contrib.markup',
    'django.contrib.sitemaps',
    'django.contrib.humanize',
    'django.contrib.comments',
    'django_faces',
    'django_openid',
    'blog',
    'gallery',
    'tagging',
    'firefly.utils',
    'firefly.my_comments',
)
COMMENTS_APP = 'firefly.my_comments'

Next, in file my_comments.py:

from django import forms
from django.utils.translation import ugettext_lazy as _
from django.contrib.comments.forms import CommentDetailsForm

class CommentForm(CommentDetailsForm):
    email = forms.EmailField(label=_("Email address"), required=False)

def get_form():
    return CommentForm

That's it! By the way, you can change other behaviour too. Just look at the sources of django/contrib/comments/__init__.py file.
