PYTHON/DJANGO：“SUser.user”必须是“用户”实例

Question

我在将新的自定义用户添加到数据库时遇到问题。我知道在互联网上有一些关于它的线索，但我无法找到解决我的问题的方法。击中后“提交”，在注册页面的模板按钮是在这里：

{% extends 'strona/Main.html' %} 
{% block body %} 
< form action="" method="post" enctype="multipart/form-data" > 
    {% csrf_token %} 
    {% for field in form %} 
     {{ field.label_tag }} 
     </br> 
     {{ field }} 
     </br> 
     </br> 
    {% endfor %} 
    < button type="submit" class="btn btn-success">Submit</button > 
</form> 
{% endblock %} 

它口口声声说：“不能分配” < SimpleLazyObject：在0x038B5A70 < django.contrib.auth.models.AnonymousUser对象>>” ：“SUser.user”必须是“用户”实例。“

请问有人能帮我吗？ 亲切的问候。

Django延迟加载request.user，以便它可以是User或AnonymousUser，具体取决于身份验证状态。

if request.user.is_authenticated(): #then request.user will be `User` instance 
    newuser = form.save(commit=False) 
    newuser.user = request.user 
    newuser.save()
