注册自己的models.py到admin后台

from django.contrib import admin
from jax import models

# Register your models here.


admin.site.register(models.UserInfo)
admin.site.register(models.Blog)
admin.site.register(models.Category)
admin.site.register(models.Tag)
admin.site.register(models.Article)
admin.site.register(models.Article2Tag)
admin.site.register(models.ArticleDetail)
admin.site.register(models.ArticleUpDown)
admin.site.register(models.Comment)

扩展django默认的用户表

# settings.py文件还可以更改语言类型

LANGUAGE_CODE = 'zh-hans'

settings.py

AUTH_USER_MODEL = 'jax.UserInfo'
