django-exmodel 0.0.2

Makes your Django models extendable.

The ex-model lets you extend models in apps by adding mixins to them. The mixins can override fields and methods of the original model.

Example:

# file: staff.models
from django.db import models
from exmodel import Model, extend_model


class Person(Model):
    name = models.CharField(max_lenth=10)

    def __unicode__(self):
        return self.name

    class Meta:
        app_label = 'staff'
        verbose_name = 'Person name'


class PersonMixin(object):
    name = models.CharField(max_lenth=500)
    alias = models.CharField(max_lenth=500)

    def __unicode__(self):
        return u'%s (%s)' % (self.name, self.alias)

    class Meta:
        verbose_name = 'Person name and alias'


extend_model('staff.Person', PersonMixin)
