Django构造函数和mixin

Question

我有一个模型是这样的：

class Base(models.Model):
  pass

class Mixin1(Base):
  active = models.BooleanField(default=False)

class Mixin2(Base):
  name = models.CharField(max_length=200,blank=False,null=False)

class Organization(Mixin1, Mixin2, Base):
  pass

这很好：

^{pr2}$

但这并不能：

organization = Organization(name='name', active=True)
organization.save()

Django在构造函数上出错，错误为：

TypeError: 'active' is an invalid keyword argument for this function

a关于混音我有什么遗漏吗？

更新我看到的内容： 使用一个新的PostgreSQL数据库和一个新的shell。

Answer 1

我把一个旧文件挂起来了。我从组织.py到组织.py. 因为某种原因，组织.pyc被卡住了，正被另一个模型文件导入。令人沮丧的。在

Answer 2

我试过了，我成功了。在

In [2]: model = Model(name='name')
In [3]: model.active = True
In [4]: model.save()

In [5]: model = Model(name='name2', active=True)
In [6]: model.save()

In [9]: Model.objects.all()
Out[9]: [<Model: Model object>, <Model: Model object>]

问题应该出在别的地方。在
