Django 有一个管理面板，允许您编辑数据库中的记录，它是自动生成的。我的模型有一个 TextField 字段，我需要在页面中添加一个降价编辑器，并为此字段添加/编辑一个条目。

如何才能做到这一点？我只看到了完全改变整个页面的选项，但我想有点血腥

PS如何在我的情况下添加降价编辑器 - 添加到页面

管理面板的照片

我需要它my actions IssuesNumberChange不显示为object (....) а, as IssuesNumberChange.publications。我怎样才能做到这一点？

models.py：

class IssuesNumberChange(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    publication = models.ForeignKey(Publication, on_delete=models.CASCADE)
    volume_of_implement = models.SmallIntegerField()
    new_number_of_issues = models.SmallIntegerField()

    class Meta:
        verbose_name = "Issues Number Change"
        verbose_name_plural = "Issues Number Changes"

admin.py：

@admin.register(models.IssuesNumberChange)
class IssuesNumberChangeAdmin(admin.ModelAdmin):
    list_display = ['publication', 'volume_of_implement', 'new_number_of_issues']

код от модели Publication：

class Publication(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    name = models.CharField(max_length=500)

我的问题是我想通过网站上的表格更新用户的个人资料照片。成功提交表单后，我的代码不显示错误，并且头像保存到 /media/avatars/。但同时，当更新个人资料页面或进入管理面板中的用户个人资料时，头像并没有改变，之前的头像被保存了。通过管理面板更改头像本身也很有效。我将非常感谢任何提示。以前，将头像分配给特定用户时会出现问题，但是这行代码：instance=request.user 帮助了我。例如，其中可能存在问题吗？

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):
    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, verbose_name='Пол')

@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()

表格.py：

from .models import Kind
from django.forms import ModelForm

class BookForm(ModelForm):

    class Meta:
        model = Kind
        fields = ['avatar']

视图.py：

from django.contrib.auth import authenticate, login
from django.shortcuts import render, redirect
from django.core.files.storage import FileSystemStorage
from Вход.forms import *
from .models import *

def profilee(request):
    if not request.user.is_authenticated:
        return redirect("/accounts/login")
    else:
        if request.method == 'POST':
            form = BookForm(request.POST, request.FILES, instance=request.user)

            if form.is_valid():
                form.save()
        else:
            form = BookForm()

        return render(request, 'registration/profile.html', {'form' : form})

def LogoutView(request):
    return redirect("/accounts/login")

模板：

<div>
 {% if not user.profile.avatar %}
 {% if user.profile.kind == "М" %}
 <div class="block">
 <img src="{% static 'image/m.png' %}" class="img-lg rounded-circle mb-4 imagero round" alt="image">
 </div>
 {% endif %}

 {% if user.profile.kind == "Ж" %}
 <div class="block">
 <img src="{% static 'image/j.png' %}" class="img-lg rounded-circle mb-4 imagero round" alt="image">
 </div>
 {% endif %}
 {% endif %}

 {% if user.profile.avatar %}
 <img src="{{ user.profile.avatar.url }}" class="img-lg rounded-circle mb-4 imagero round" alt="image">
{% endif %}


<form method = "post" enctype="multipart/form-data">
 {% csrf_token %}
 {{ form.as_p }}
 <button type="submit">Upload</button>
</form>

<h4>{% if user.first_name %}{{ user.first_name }}{% endif %} {% if user.last_name %}{{ 
 user.last_name }}{% endif %}</h4>
 <p class="text-muted mb-0">Social Activist</p>
</div>
