Add optional fields to django's built-in comments app

I wanna add a thumb-up and thumb-down counter as comments' fields. And I added two IntegerFields to a class called 'MyComment' in models.py. And I also use a forms.py like this:

from django import forms
from django.contrib.comments.forms import CommentForm
from blog.models import MyComment

class MyCommentForm(CommentForm):
    thumbs_up = forms.IntegerField()
    thumbs_down = forms.IntegerField()

def get_comment_model(self):
    return MyComment

def get_comment_create_data(self):
    data = super(MyCommentForm, self).get_comment_create_data()
    data['thumbs_up'] = self.cleaned_data['thumbs_up']
    data['thumbs_down'] = self.cleaned_data['thumbs_down']
    return data

After that, when I submit a comment, it says that: thumbs_up and thumbs_down are required. How do I make them optional, just like the default field "Users' URL"? Any help will be appreciated.

OK, here's my MyComment model:

from django.contrib.comments.models import Comment

class MyComment(Comment):
    thumbs_up = models.IntegerField(default=0)
    thumbs_down = models.IntegerField(default=0)

you should set field optional in model like this:

class MyComment(Comment):
    thumbs_up = models.IntegerField(default=0)
    thumbs_down = models.IntegerField(default=0)

take a look at Field options for more information. And change your form like this:

class MyCommentForm(CommentForm):
    thumbs_up = forms.IntegerField(required=False)
    thumbs_down = forms.IntegerField(required=False)

and change get_comment_create_data like this:

def get_comment_create_data(self):
    data = super(MyCommentForm, self).get_comment_create_data()
    data['thumbs_up'] = self.cleaned_data.get('thumbs_up', 0)
    data['thumbs_down'] = self.cleaned_data.get('thumbs_down', 0)
    return data

Modify your Model... it's work.

class MyComment(Comment):
    thumbs_up = models.IntegerField(default=0, blank=True)
    thumbs_down = models.IntegerField(default=0, blank=True)

blank attribute let you to be set null in admin panel, and null attribute let you set null in database (null=True). i think in your case you just need to set blank=True, because you set default for your fields in model.

You can tell field to be optional by setting "required":

class MyCommentForm(CommentForm):
    thumbs_up = forms.IntegerField(required=False)
    thumbs_down = forms.IntegerField(required=False)
