Python Django请求URL被追加

我访问管理界面，尝试在django中添加支持用户。这是一个带有用户名和电子邮件的表单。表单数据已成功过帐。成功发布请求后，我必须重定向到127.0.0.1:8000/admin/auth/user/。然而，在127.0.0.1:8000/添加支持用户中，如果用户已经存在，url会像这样更改127.0.0.1:8000/添加支持用户/添加支持用户，如果用户已经存在，我会再次请求它这样的127.0.0.1:8000/添加支持用户/添加支持用户/添加支持用户（每次都会追加）当创建新用户时，url更改如下127.0.0.1:8000/add\u support\u user/add\u support\u user，因此它显示了500个错误页面，'127.0.0.1:8000/add\u support\u user/add\u support\u user'不存在。我在这里犯了什么错误

更改您的表单

<form role="form" action="add_support_user/" method="post">

对此

<form role="form" action="" method="post">

group\u obj=group.objects.get（name='support\u group'）

检查数据库中是否存在此组please@Nikitka为什么？这和这个问题有什么关系？@DanielRoseman大约500error@Nikitka是支持组存在。@发布后不执行Nikitka url重定向。为什么？或者用
