问题[django-model]

帮助我了解如何从rgb模型中获取rgb_name数据，现在我只得到rgb_numb

模型.py

class Rgb(models.Model):
    rgb_numb = models.CharField('Номер', max_length=10)
    rgb_name = models.CharField('Наименование', max_length=500)
    rgb_mod = models.CharField('Наименование', max_length=500)

    def __str__(self):
        return self.rgb_numb
  
class Reestr_db(models.Model):
    id_numb = models.CharField('Номер протокола', max_length=10, blank=True)
    rgb_numb = models.ForeignKey(rgb, on_delete=models.PROTECT, related_name="result_rgb_numb", verbose_name="Номер")
    rgb_name = models.ForeignKey(rgb, on_delete=models.PROTECT, related_name="result_rgb_name", verbose_name="Наименование")

视图.py

def reestr(request):
    bazar = rgb.objects.all()
    baza = reestr_db.objects.order_by('id_numb')
    datar = {
        'baza': baza,
        'bazar': bazar
    }
    return render(request, 'main/reestr.html', datar)

注册.html

  {% for el in baza %}
        <tr>
            <td>{{ el.result_rgb_numb.rgb_mod }}</td>
            <td>{{ el.result_rgb_name.rgb_name }}</td>

我正在努力在网站上注册。我的问题是内置的用户模型保存成功，而另一个相关模型的元素无法保存并且在某处丢失（种类）。我认为问题出在 .save() 的错误组织上，但我不明白到底是什么问题。创建新用户的测试进展顺利。结果，使用输入的数据创建了一个用户，但 Kind 除外。我部分遵循了本教程：https ://tproger.ru/translations/extending-django-user-model/ ，但显然我在某处犯了错误。我真的希望能帮上忙！

模型.py

from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver

class Kind(models.Model):
    class Kinds(models.TextChoices):
        M = '1', "М"
        F = '2', "Ж"

    class Confirmations(models.TextChoices):
        S = '1', "Не подтвержден"
        N = '2', "Подтвержден"

    user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile')
    avatar = models.ImageField(null=True, blank=True, upload_to="avatars/", verbose_name='Изображение')
    kind = models.CharField(max_length=1, choices=Kinds.choices, verbose_name='Пол')
    confirmation = models.CharField(max_length=1, default='1', choices=Confirmations.choices, verbose_name='Подтверждение')

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        Kind.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
    instance.profile.save()

        if user_form.is_valid() and kind_form.is_valid():

            new_user.set_password(user_form.cleaned_data['password'])
            new_user.save()

            new_kind = kind_form.save()
            new_kind.save()

    else:
