django-exmodel 0.0.2

ex-model允许您通过添加混入到应用中的模型来扩展模型。混入可以覆盖原始模型中的字段和方法。

示例

# 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)
