PYTHON/DJANGO: “SUser.user” must be a “User” instance

Question

I have a problem with adding new custom user to the database. I know thare's some threads about it on the internet but I couldn't find solution for my problem. After hitting "Submit" button in registration page which template is here:

{% 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 %}

it keeps saying that: "Cannot assign "< SimpleLazyObject: < django.contrib.auth.models.AnonymousUser object at 0x038B5A70 >>": "SUser.user" must be a "User" instance."

Please could someone help me out? Kind regards.

What are you trying to do? This is a registration form, so the user can't possibly be logged in yet. So why are you trying to save the current user to the new user object? — Daniel Roseman
So how could I save new user after " if password1 == password2:" ? — LOLOLOLO

Django lazy loads request.user so that it can be either User or AnonymousUser depending on the authentication state.

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