Django模型无法通过管理界面工作

Question

我正在一个使用django项目的拍卖网站上工作。我有一个投标模型。我已经在admin.py中注册了该模型，但当我尝试从管理界面出价时，它不会在主网站页面中更新。但通过网站的出价是完美的更新和其他模型都是完美的工作。

型号.py:

from django.contrib.auth.models import AbstractUser
from datetime import datetime
from django.db import models
CHOICES = (
('fashion','Fashion'),
('tools', 'Tools'),
('toys','Toys'),
('electronics','Electronics'),
('home accesories','Home accessories'),
('books','Books'),
)
class User(AbstractUser):
pass
class Bid(models.Model):
user = models.CharField(max_length=64)
title = models.CharField(max_length=64)
listingid = models.IntegerField()
bid = models.IntegerField()
class Listing(models.Model):
owner = models.CharField(max_length=64)
title = models.CharField(max_length=64)
description = models.TextField()
price = models.IntegerField()
category = models.CharField(max_length=64, choices=CHOICES, default='fashion')
link = models.CharField(max_length=10000,default=None,blank=True,null=True)
time = models.CharField(max_length=64, default= datetime.now().strftime(" %d %B %Y %X "))
class Comment(models.Model):
user = models.CharField(max_length=64)
time = models.CharField(max_length=64, default= datetime.now().strftime(" %d %B %Y %X "))
comment = models.TextField()
listingid = models.IntegerField()

admin.py:

from django.contrib import admin
from .models import User, Listing, Bid, Comment
# Register your models here.
admin.site.register(Bid)
admin.site.register(User)
admin.site.register(Listing)
admin.site.register(Comment)

这是视图中bidsubmit的功能。py(我在这个文件中导入了投标模型(：

def bidsubmit(request,listingid):
current_bid = Listing.objects.get(id=listingid)
current_bid = current_bid.price
if request.method == "POST":
user_bid = int(request.POST.get('bid'))
if user_bid > current_bid:
listing_items = Listing.objects.get(id=listingid)
listing_items.price = user_bid
listing_items.save()
try:
if Bid.objects.filter(id=listingid):
bidrow = Bid.objects.filter(id=listingid)
bidrow.delete()
b = Bid()
b.user=request.user.username
b.title = listing_items.title
b.listingid = listingid
b.bid = user_bid
b.save()
except:
b = Bid()
b.user=request.user.username
b.title = listing_items.title
b.listingid = listingid
b.bid = user_bid
b.save()

response = redirect('auctions:listingpage',id=listingid)
response.set_cookie('errorgreen','bid successful!!!',max_age=3)
return response
else :
response = redirect('auctions:listingpage',id=listingid)
response.set_cookie('error','Bid should be greater than current price',max_age=3)
return response
else:
return redirect('auctions:index')

确保您已在项目settings.py中注册了应用程序(在INSTALLED_APPS中附加包含Bid模型的应用程序名称(，然后运行其相关的管理命令(即manage.py makemigrations和manage.py migrate(。我希望这能解决你的问题。
