optional fields in django models

Question

I have the following model in django.

class Link(models.Model):     name = models.CharField(max_length=100)     url = models.CharField(max_length=100)     tag = models.CharField(max_length=100)      def __unicode__(self):         return self.name 

I need the url field to be optional. How do I do this?

Add the attribute blank=True. Optionally, you can also make the field NULLable with null=True.
