首先我的django版本为
django.VERSION
(1, 8, 6, 'final', 0)

admin.py内容如下

from django.contrib import admin
from books.models import Publisher,Author,Book
# Register your models here.

class RecordAdmin:
    list_display=('title','publisher','publication_date')
    list_filter=('publisher','publication_date')
    ordering=('-publication_date',)
    search_fields=('title',)
    pass

        
admin.site.register(Publisher)
admin.site.register(Author)
admin.site.register(Book,RecordAdmin)

但是启动server的时候会有如下报错

D:\Users\rongweiwei799\mysite>manage.py runserver

请教下各位如何解决这个问题？
