super（）参数1必须是类型，而不是非

Question

在我的django应用程序的一个模块中，一个类在使用super。。。在

class LinkshareExternalAffiliateProperties(AffiliateExternalProperties):

    def __init__(self, aggregator_affiliate_id, account_username, account_password, api_token):
        super(LinkshareExternalAffiliateProperties, self).__init__(aggregator_affiliate_id)
        self.account_username = account_username
        self.account_password = account_password
        self.api_token = api_token

class AffiliateExternalProperties(object):

    def __getattribute__(self, attr):
        sources = super(AffiliateExternalProperties, self).__getattribute__('__sources__')
        if attr in sources:
            return self.get(attr)
        else:
            return super(AffiliateExternalProperties, self).__getattribute__(attr)

当代码被调用时，我得到一个错误：super（）参数1必须是type，而不是None LinkshareExternalAffiliateProperties如何计算为None？它是这个新实例的类！！同一模块中的其他类此时也不可用。在

Answer 1

你在分配完课程后不宣布。以下将导致您看到的错误：

class foo(object):
    def x(self):
        print "foo"

class bar(foo):
    def x(self):
        super(bar, self).x()

baz = bar
bar = None

a = baz()
a.x()

Gunicorn有一个bug：

djangorun_gunicorn+重新加载

one possibility to fix reload using Django 'un_gunicorn' command with manage.py would be to consider that reload == reexec. So we are making sure we reload all modules. But with this solution the process id will change and some supervisor may not be abble to detect the change if they aren't using the pidfile. (In other word we should strongly advise people to use gunicorn_django command if they want HUP support.)
