我想调用password_generator方法时注册类被实例化，并分配值返回从方法到密码字段。
当寄存器对象被实例化时，为什么我得到
/register运行时错误
调用Python对象时超过最大递归深度
这是密码
models.py
class Register(models.Model):
created_at = models.DateTimeField(auto_now_add=True)
email = models.EmailField(max_length=120, blank=False, null=False)
password = models.TextField(blank=False, null=False)
firstname= models.CharField(max_length=120, blank=False, null=False)
lastname = models.CharField(max_length=120, blank=False, null=False)
phonenumber = models.CharField(max_length=120, blank=True, null=True)
def __init__(self, *args, **kwargs):
self.password = Register().password_generator()
#Generate random login password for candidate
def password_generator(self, size=30, chars=string.ascii_letters + string.digits + string.punctuation):
return ''.join(random.choice(chars) for i in range(size))
来自终端的日志

self.password = Register().password_generator()
如何解决这个问题？
经过多次尝试，我意识到我试图调用的函数处于无限循环中。要访问password_generator（）方法，我必须执行寄存器（）。password_generator（）。所以这也意味着__init__方法被调用-因为寄存器（）。在__init（）__中，我再次调用寄存器（）。这就是为什么它变成了一个无限循环。为了解决这个问题，我们必须使用：
def __init__(self, *args, **kwargs):
self.password = self.password_generator()
