【英文标题】：AttributeError: type object 'Product' has no attribute '_meta'

【问题描述】：

我是 Python / Django 的新手，所以请多多包涵。我无法运行任何命令，并且终端每次都会产生相同的错误。

我的模型如下所示：

from django.db import models

# Create your models here.
class Product(models.Model):
    item_name = models.CharField(max_length=100)
    item_price = models.IntegerField()
    item_image = models.ImageField()

    class Meta:
        ordering = ['item_name']

Admin.py

from django.contrib import admin

# Register your models here.
from .models import Product

class Product(admin.ModelAdmin):
    pass

admin.register(Product)(admin.ModelAdmin)

【参考方案1】：

从追溯看来，问题来自您的admin.py。如果您使用的是 admin.register 装饰器，请确保您使用正确：

@admin.register(Product)
class ProductAdmin(admin.ModelAdmin):
    pass

或者，您可以使用admin.site.register 函数：

class ProductAdmin(admin.ModelAdmin):
    pass

admin.site.register(Product, ProductAdmin)
