推荐答案
您已经为网址设置了命名空间:
You've set a namespace for your urls:
app_name = 'account'
在使用reverse/reverse_lazy或{% url %}反转URL时，需要使用该名称空间:
You need to use that namespace when reversing urls with reverse/reverse_lazy or {% url %}:
LOGIN_REDIRECT_URL = reverse_lazy('account:dashboard')
LOGIN_URL = reverse_lazy('account:login')
LOGOUT_REDIRECT_URL = reverse_lazy('account:logout')
