AttributeError：类型对象“ Product”没有属性“ _meta” [英] AttributeError: type object 'Product' has no attribute '_meta'

问题描述

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

I am pretty new in Python / Django so please bear .. I am unable to run any commands and the terminal produces the same error every time.

我的模型看起来像这样：

My Model looks like this:

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

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)

跟踪：-

推荐答案

从回溯来看，问题似乎出在您的 admin.py 上。如果您使用的是 admin .register 装饰器，请确保您正确使用它：

It seems from the traceback that the problem is coming from your admin.py. If you are using the admin.register decorator make sure you are using it right:

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

或，则可以使用 admin.site.register 函数：

class ProductAdmin(admin.ModelAdmin):
    pass

admin.site.register(Product, ProductAdmin)
