我感谢你的帮助。非常感谢

您已经为URL设置了名称空间：

app_name = 'account'

使用

reverse

reverse\u lazy

或

{%url%}

反转url时，需要使用该命名空间：

LOGIN_REDIRECT_URL = reverse_lazy('account:dashboard')
LOGIN_URL = reverse_lazy('account:login')
LOGOUT_REDIRECT_URL = reverse_lazy('account:logout')

可能在指定{%url'appname:views%}时指定了错误的appname

例如：

wrong - {% url 'accuant:dashboard' %}
right - {% url 'account:dashboard' %}
