疑问

我想如何重定向发送请求的同一个网址，我尝试使用request.path，但它将我重定向到/ accounts / login / url，这是不希望的。

您需要做的是跟踪显示登录表单时引荐来源的内容，可能会将该值存储在用户会话中，然后在用户成功登录后将用户重定向回该网址。

有些事情：

def login_user(request):
    if request.POST:
        sform = LoginForm(request.POST)
        rform = UserForm()
        if sform.is_valid():
            username = request.POST.get('username')
            password = request.POST.get('password')
            user = authenticate(username = username,password = password)
            if user is not None:
                if user.is_active:
                    login(request,user)
                    return redirect(request.path)
                else:
                    state = "Your account is not active."
                    #or first set the user to is active and then log in 
                    return redirect(req.session['after_login_url'],user = user)
                return render_to_response('home.html',{'state':state,'user':user},context_instance = RequestContext(request))
            else:
                state = "Incorrect Username or Password"
                #sform = LoginForm()
                form = LoginForm()
                return render_to_response('register.html',{'state':state,'sform':sform,'rform':rform,'form':form},context_instance = RequestContext(request))
        else:
            state = "Invalid form"
            dLoginForm = LoginForm()
            rform = PartialSignupForm()
            return render_to_response('register.html',{'sform':sform,'rform':rform,'form':form},context_instance = RequestContext(request))
    else:
        dLoginForm = LoginForm()
        rform = PartialSignupForm()
        req.session['after_login_url'] = req.META.get('HTTP_REFERER')
        return render_to_response('category.html',{'dLoginForm':dLoginForm,'rform':rform},context_instance = RequestContext(request))

当然，您还应该添加检查以确保HTTP_REFERER标头存在，并确保after_login_url密钥存在（并且可能具有合理的值，以防外部站点直接链接到您的登录页面，或类似的），并且如果这些测试中的任何一个失败（例如可能是用户的个人资料页面或您的网站索引页面），则可以安全地退回。
