PYTHON/DJANGO："SUser.user"必须是"User"实例

Question

我在向数据库添加新的自定义用户时遇到问题。我知道网上有一些关于这个问题的帖子，但我找不到解决问题的办法。点击注册页面中的“提交”按钮后，这里是哪个模板：

{% 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 %}

它一直说：“无法分配”

有人能帮我吗？诚挚的问候。

Django延迟加载request.user，以便它可以是User或AnnamousUser，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()
