(admin.E108) The value of 'list_display[0]' refers to 'productname', which is not a callable, an attribute of 'ProductAdmin', or an attribute or method on 'product.Product'.

models.py

# 创建产品表

admin.py

class ProductAdmin(admin.ModelAdmin):

    inlines = [ApisAdmin]

admin.site.register(Product, ProductAdmin)    # 把产品模块注册到Django admin后台并能显示

执行后：

D:\autotestplat>python manage.py makemigrations
SystemCheckError: System check identified some issues:

<class 'product.admin.ProductAdmin'>: (admin.E108) The value of 'list_display[0]' refers to 'productname', which is not a callable, an attribute of 'ProductAdmin', or an attribute or method on 'product.Product'.

错误指 在admin.py文件中  'ProductAdmin' 的属性  list_display[0] (即productname)  在models.py 文件中的 Product类中找不到

查找源代码可发现在ProductAdmin类中为productname，而在Product中为 productName，两边未对应，所以报以上错

代码更改并运行：

admin.py

class ProductAdmin(admin.ModelAdmin):
    list_display = ['productName', 'productDesc', 'producter', 'create_time', 'id']
    inlines = [ApisAdmin]

admin.site.register(Product, ProductAdmin)    # 把产品模块注册到Django admin后台并能显示

运行：

D:\autotestplat>python manage.py makemigrations
