Django模型无法通过管理界面工作

问题描述

我正在使用django项目在拍卖网站上工作。我有一个出价模型。我已经在admin.py中注册了该模型，但是当我尝试从管理界面放置出价时，它并没有在主网站页面上更新。但是通过网站出价可以完美更新，其他模型也可以完美运行。

models.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 views.py 中的提交投标的功能（我已在此文件中导入了出价模型）：

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')

解决方法

请确保您已在项目settings.py中注册了您的应用（在Bid中添加了包含INSTALLED_APPS模型的应用名称），然后运行它的相关管理命令（即{ {1}}和manage.py makemigrations）。我希望这能解决您的问题。
