为什么我的 URL 没有更改为我的渲染模板名称？

Question

我注意到登录后我的 URL 不正确。我怎样才能正确地做到这一点？

当前输出网址：

http://127.0.0.1:8000/login_user/

正确的输出 URL 必须是：

http://127.0.0.1:8000/

我怎样才能做到这一点？

login.html：

 <form class="form-horizontal" role="form" action="{% url 'ksvt:login_user'%}" method="post" enctype="multipart/form-data">
                    {% csrf_token %}
                    <div class="form-group">
                        <label class="control-label col-sm-2" for="id_username">
                            Username:
                        </label>
                        <div class="col-sm-10">
                            <input id="id_username" maxlength="30" name="username" type="text">
                        </div>
                    </div>
                    <div class="form-group">
                        <label class="control-label col-sm-2" for="id_password">
                            Password:
                        </label>
                        <div class="col-sm-10">
                            <input id="id_password" maxlength="30" name="password" type="password">
                        </div>
                    </div>
                    <div class="form-group">
                        <div class="col-sm-offset-2 col-sm-10">
                            <button type="submit" class="btn btn-success">Submit</button>
                        </div>
                    </div>

您只是在渲染中更改模板，这不会将您重定向到索引页面。要更改 url，如果用户通过身份验证，您需要在视图中返回 redirect 对象：

if user is not None:
    if user.is_active:
        login(request, user)
        return redirect('index')
