Django-登录的用户未填充在admin.py中

Question

I'm trying to create a form to when the current logged in user makes a submission the user column in admin.py gets populated with the logged in user.

My problem: The user column gets populated when a new user gets created using the CustomUserCreationForm however when the newly created user makes a form submission with the form listed below, the user column doesn't get populated.

The Custom User Model that I'm trying to get the username from is located in from users.models import CustomUser so I'm not sure why this isn't working.

How do I get the current logged in user to populate in admin.py in the users column with the form listed below?

Any help i gladly appreciated, thanks.

Code Below:

Try this

forms.py

import os

from django import forms
from django.forms import ModelForm

from django.forms import widgets
from django.utils import six
from django.utils.safestring import mark_safe
from django.utils.translation import ugettext_lazy as _
from django.template.defaultfilters import filesizeformat

from avatar.conf import settings
from avatar.models import Avatar
from .models import Listing


class HomeForm(forms.ModelForm):

    class Meta:
        model = Listing
        fields = ('name', 'address', 'zip_code', 'mobile_number', 'cc_number', 'cc_number', 'cc_expiration', 'cc_cvv')

Add in models file

class ListingManager(models.Manager):
    def save_from_object(self, request, obj):
        obj.user = request.user
        obj.save()

Add Update your Listing Model with objects as new manager

class Listing (models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, null=True)
    created =  models.DateTimeField(auto_now_add=True, null=True)
    updated = models.DateTimeField(auto_now=True)
    name = models.CharField(max_length=100)
    address = models.CharField(max_length=100)
    zip_code = models.CharField(max_length=100)
    mobile_number = models.CharField(max_length=100)
    cc_number = models.CharField(max_length=100)
    cc_expiration = models.CharField(max_length=100)
    cc_cvv = models.CharField(max_length=100) 

    objects = ListingManager()

This should work, Also I am not sure about your idea of keeping user as OneToOneField (This will not allow having multiple records with same user instance), I think you need to change it to ForeignKey. Refer What's the difference between django OneToOneField and ForeignKey?
