使用Django模型,我想实现这个目标:
class Foo(models.Model):
name = models.CharField(max_length=50)
#wrapping the save function, including extra tasks
def save(self, *args, **kwargs):
super(Foo, self).save(*args, **kwargs)
if extra_param:
...do task 1
else:
...do task 2
虽然装箱Foo我想传递
Foo(name="Bill Gates",extra_param=True).save() # now triggers the task 1
Foo(name="Bill Gates").save() # now triggers the task 2
如何做到这一点?我也对任何其他建议持开放态度:))

您可以在模型中定义非持久字段。
class Foo(models.Model):
name = models.CharField(max_length=50)
extra_param = False
def save(self, *args, **kwargs):
...
print self.extra_param
或者,您可以这样做:
Foo(name="Bill Gates").save(extra_param=True)
def save(self, *args, **kwargs):
...
print kwargs["extra_param"]
