Python Django在执行向后关系查询时，在使用管理器时发生了超过最大递归深度的错误

python django recursion model

Python Django在执行向后关系查询时，在使用管理器时发生了超过最大递归深度的错误,python,django,recursion,model,Python,Django,Recursion,Model,代码如下：类车源 class CarSource(models.Model): status = models.CharField(max_length=1, blank=True, null=True) dealer = models.ForeignKey(Dealer, blank=True, null=True, \ on_delete=models.SET_NULL, related_name='cars', \

代码如下：

类车源

class CarSource(models.Model):
    status = models.CharField(max_length=1, blank=True, null=True)
    dealer = models.ForeignKey(Dealer, blank=True, null=True, \
                  on_delete=models.SET_NULL, related_name='cars', \
                  verbose_name=u'dealer own this car')
    objects = CarSourceManager()

等级经销商

class Dealer(models.Model):
    ...

类别CarSourceManager：

class CarSourceManager(models.Manager):
    ''' Manage query in CarSource, filter data that was processed successfully.'''
    def get_query_set(self):
        return super(self.__class__, self).get_query_set().filter(status='S')

当我执行此命令时：

from ... import Dealer
d = Dealer.objects.get(id = 2)
d.cars.all()

出现如下错误：

File "/...path..of..error..file../apps/car/managers.py", line 9, in all
return super(self.__class__, self).all().filter(status='S')
File "/...path..of..error..file../apps/car/managers.py", line 9, in all
return super(self.__class__, self).all().filter(status='S')
File "/...path..of..error..file../apps/car/managers.py", line 9, in all
return super(self.__class__, self).all().filter(status='S')
File "/...path..of..error..file../apps/car/managers.py", line 9, in all
return super(self.__class__, self).all().filter(status='S')
File "/...path..of..error..file../apps/car/managers.py", line 9, in all
return super(self.__class__, self).all().filter(status='S')
File "/...path..of..error..file../apps/car/managers.py", line 9, in all
return super(self.__class__, self).all().filter(status='S')
File "/...path..of..error..file../apps/car/managers.py", line 9, in all
return super(self.__class__, self).all().filter(status='S')
RuntimeError: maximum recursion depth exceeded while calling a Python object

我覆盖了

CarSourceManager

中

models.Manager

的

get\u query\u set

，显然，它继续以递归方式调用它。我看了经理的代码，但没看懂，请帮帮我。

看这个答案：

基本上你不能用

super(self.__class__, self)

使用

相反
