Django MixIn To Not Define __unicode__ Method

A lot of the models I make just need to return one instance variable as it's 'name' and defining __unicode__ method for each one just to change the instance variable seemed to be a waste of time. So here is what I did so I can type less.
Here is an example using the class variable name as the Unicode representation...

from django.db import models
class UnicodeReprMixIn(object):
"""
Adds a unicode representation using self._unicode.
"""
def __unicode__(self):
"""
Unocode representation of this instance.
"""
return unicode(self.__getattribute__(self._unicode))
Here is an example using the class variable name as the Unicode representation...
class Company(models.Model, UnicodeReprMixIn):
"""
A representation of a comic book company.
"""
name = models.CharField(max_length=255)
slug = models.SlugField()
logo = models.ImageField(upload_to=os.path.join('upload', 'company_logos'))
url = models.URLField(verify_exists=True)
_unicode = "name"
