网上看到很多解决办法。但对于我来说，

好像加个post_change_redirect这个参数是最有效的。

from django.conf.urls import urlfrom . import viewsfrom django.core.urlresolvers import reverseurlpatterns = [    # post views    # url(r'^login/$', views.user_login, name='login'),    url(r'^login/$', 'django.contrib.auth.views.login', name='login'),    url(r'^logout/$', 'django.contrib.auth.views.logout', name='logout'),    url(r'^logout-then-login/$', 'django.contrib.auth.views.logout_then_login', name='logout_then_login'),    url(r'^password-change/$', 'django.contrib.auth.views.password_change',        {'post_change_redirect': '/account/password-change-done/', 'current_app': 'account'},        name='password_change'),    url(r'^password-change-done/$', 'django.contrib.auth.views.password_change_done',        name='password_change_done'),    url(r'^$', views.dashboard, name='dashboard'),]
