Question

我有一个简单的视图，可以检查是否有帖子数据，如果是，请使用edit_profile更新用户数据。否则得到表格用户和显示的数据。

问题：/ profile / edit中的AttributeError'AnonymousUser'对象没有属性'_meta'

我认为可能是# Handles the get request - if no post info is submitted then get the form and display it on the edit profile page. else: form = UserChangeForm(instance=request.user) args = {'form': form} return render(request, 'accounts/profile_edit.html', args)视图中的这一行

view.py edit_profile

不确定是什么。这是def edit_profile(request): # Handle post request - if the user submits a form change form details and pass the intance user if request.method == 'POST': form = UserChangeForm(request.POST, intance=request.user) if form.is_valid(): form.save() return redirect('accounts/profile') # Handles the get request - if no post info is submitted then get the form and display it on the edit profile page. else: form = UserChangeForm(instance=request.user) args = {'form': form} return render(request, 'accounts/profile_edit.html', args)

{% extends 'base.html' %}

{% block head %}
<title>Profile</title>
{% endblock %}

{% block body %}
<div class="container">
    <form method="post">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit">Save Changes</button>
    </form>
</div>

{% endblock %}

Answer 1

您无法更新AnnonymousUser（即为未登录用户设置的特殊用户类）。您的问题的一个解决方案是通过使用login_required装饰器修饰您的视图，禁止未经过身份验证的用户查看此页面。

Answer 2

您收到错误，因为没有用户登录。您可以使用try方法。

在您的代码中使用if user.is_authenticated

if user.is_authenticated():
  if request.method == 'POST':
    form = UserChangeForm(request.POST, intance=request.user)

    if form.is_valid():
        form.save()
        return redirect('accounts/profile')
# Handles the get request - if no post info is submitted then get the form and display it on the edit profile page. 
    else:
      form = UserChangeForm(instance=request.user)
      args = {'form': form}
      return render(request, 'accounts/profile_edit.html', args)
else:
    raise PermissionDenied
