Python Django视图返回POST而不是GET请求

因此，我有这些使用POST请求注册和登录的工作视图，这两个请求都返回profile.html

问题是，当我提交表单（根据cmd）时，登录和注册视图会将一篇文章返回到登录或注册URL，以运行必要的功能。 这意味着它只是呈现profile.html，而不是运行其查看功能。

我如何让提交的表单发送到纵断面图，同时仍让他们为各自的功能发送帖子

已经有账户了吗

登录页面应该被访问两次：当用户被重定向到该页面时，使用GET；当用户发送填写好的表单时，再次使用POST。您的视图逻辑应处理两种类型的申请：

def用户登录（请求）：
如有要求，请发送：
form=UserForm（request.POST）#注意，我重命名了您的表单
username=request.POST['username']
password=request.POST['password']
用户=验证（用户名=用户名，密码=密码）
如果用户不是无：
如果user.u处于活动状态：
登录（请求、用户）
返回重定向（'profile'，kwargs={username=user}）
否则：#请求已被获取
form=UserForm（）
返回呈现（请求'login.html'，{'form'：form}）
@要求
def配置文件（请求、用户名）：
user=Users.objects.get（username=username）
兴趣=兴趣.对象.过滤器（成员=用户）.values\u列表（'item'，flat=True）
info=Bios.objects.get（author=user）
上下文={
“用户”：用户，
“利益”：利益，
“信息”：信息
}
返回呈现（请求'profile.html'，上下文）

我还稍微更改了概要视图，以使用我认为是Django基于函数的视图中的最佳实践。

起初，我只是接受了带有持久性问题的更干净的代码，但我刚刚意识到我可以在重定向的同时传递username参数。所以我把它进口了，现在我们好了。谢谢@beatmaister感谢您的接受！我编辑了代码来修复它。
