my_auth.context_processors.py

Question

升级到Django 1.5后，我有一个非常奇怪的错误。当我访问我的ClientDetailView并激活Django调试工具栏时，我收到以下错误：

Traceback:

Exception Type: InternalError at /clients/5/
Exception Value: current transaction is aborted, commands ignored until end of transaction block

...我知道有时我必须停用它才能看到真正的错误，但现在如果我停用DDT，错误就会完全消失。它不应该影响生产服务器，但它仍然很烦人。

以下是有问题的观点：

class BaseSingleClient(LoginRequiredMixin,
                       generic.detail.SingleObjectMixin):

    def get_context_data(self, **kwargs):
        '''
        Add the current client object to the context.
        This will be used in the template
        '''
        context = super(BaseSingleClient, self).get_context_data(**kwargs)
        try:
            self.client = self.kwargs['client_id']
        except KeyError, e:
            self.client = self.kwargs['pk']
        context['client_obj'] = UpstreamClientModel.objects.get(pk=
                                                                self.client)
        return context


class ClientDetailView(BaseSingleClient, generic.DetailView):
    model = UpstreamClientModel
    template_name = 'clients/client_detail.html'

错误发生时正在执行的SQL：

DEBUG (0.004) SELECT "django_session"."session_key", "django_session"."session_data", "django_session"."expire_date" FROM "django_session" WHERE ("django_session"."session_key" = '0ayyigap4sphq5lvtlfy64una45o4id6'  AND "django_session"."expire_date" > '2013-05-27 10:38:44.800431+00:00' ); args=('0ayyigap4sphq5lvtlfy64una45o4id6', u'2013-05-27 10:38:44.800431+00:00')

这是最后一个查询来自BTW的地方：

my_auth.context_processors.py

def extended_auth(request):
    '''
    @allowed_user (bool) the user is either a Core team member or an admin.
    @user_groups (string) the groups the user belongs to.
    '''
    is_allowed = False
    user_groups = None
    if not request.user.is_anonymous():
        tmp = request.user.groups.values('name')
        user_groups = [g['name'] for g in tmp]
        if 'Core' in user_groups or 'Administrator' in user_groups:
            is_allowed = True
    return {'allowed_user': is_allowed, 'user_groups': user_groups, }

Answer 1

current transaction is aborted, commands ignored until end of transaction block告诉您之前的语句导致了导致自动事务回滚的错误。

您需要检查错误日志以查找先前失败的语句。如果你在Django的日志中找不到它，请查看PostgreSQL的日志。

Django的“当前事务被中止，命令被忽略，直到事务块结束”仅在升级到1.5之后
