在 Django 中编辑配置文件

Question

我想弄清楚如何从自定义 html 表单编辑和更新配置文件。 我看过有关如何使用UserChangeForm潜在地从 Django 的内置更改表单继承字段并使用它更改配置文件的教程。 但我宁愿使用我正在使用的模板附带的 html 页面。

这是个人资料页面的 html 文件：

...
<li><a href={% url editprofile %}>Edit Profile</a></li>
...

用于编辑个人资料页面的模板的 html

<form class="form-horizontal" action="app-instructor-profile.html" method="post" >
                      <div class="form-group">
                        <label for="photo" class="col-sm-2 control-label">Avatar</label>
                        <div class="col-md-6">
                          <div class="media v-middle">
                            <div class="media-left">
                              <div class="icon-block width-100 bg-grey-100">
                                <i class="fa fa-photo text-light"></i>
                              </div>
                            </div>
                            <div class="media-body">
                              <a href="#" class="btn btn-white btn-sm paper-shadow relative" data-z="0.5" data-hover-z="1" data-animated> Add Image<i class="fa fa-upl"></i></a>

我希望登录的用户单击编辑个人资料，重定向到 html 模板以编辑个人资料页面并根据所做的更改更新他们的信息。 但是，当我运行我的代码时，我收到此错误消息

“用户”对象没有“个人资料”属性

更新对 stackoverflow 进行了一些研究并对我的代码进行了一些更改

教师.py（视图）

#edit mentor profile
def edit_user(request,pk):
    user = request.user
    form = MentorProfileForm(initial={'first_name':user.first_name,'last_name':user.last_name,'email':user.email})
    if request.method == 'POST':
        if form.is_valid():
            user.first_name = request.POST['first_name']
            user.last_name = request.POST['last_name']
            user.email = request.POST['email']
            user.save()
            return HttpResponseRedirect('%s'%(reverse('profile')))
    context = {
        "form":form
    }
    return render(request, "teachers:app-instructor-profile",context)

网址.py

path('teachers/', include(([
    path('edit_user', teachers.edit_user, name='edit_user'),
], 'classroom'), namespace='teachers')),

但是，我仍然收到相同的错误消息

“用户”对象没有“个人资料”属性

Answer 1

您提到的错误很可能是由您的create_or_update信号引起的。 线

instance.profile.save()

正在尝试对您的User实例的某些profile属性调用save() 。 但是，您发布的User模型没有显示任何名为profile属性。 我不确定你想用那条线实现什么。 如果我正确理解您的代码，您将在创建新用户时尝试创建关联的Mentor 。 为此，您不需要该线并可以将其取出。
