在我的django应用程序上，我尝试注册模型，python www.example.com makemigrations，migrate工作，但在admin上找不到数据库表。manage.py makemigrations , migrate works , but no database table found on admin..

网站admin.py

from django.contrib import admin..
from .models import Product

class ProductAdmin(admin.ModelAdmin):
    prepopulated_fields = {'slug': ('product_name',)}
    list_display = ('product_name', 'price', 'stock', 'category', 'modified_date', 'is_available')

admin.site.register(Product, ProductAdmin)
