开发流程:
需求分析
草拟一些项目的大致技术点和流程
架构设计
架构师(框架 语言 数据库 缓存数据库 表设计 拆分功能 项目的报价
分组开发
任务 按模块功能分的 组长在拆分功能 每个组员写几个小功能 需要提前测试一下有没有bug
交互测试
运维上线
BBS表格创建:
from django.db import models
from django.contrib.auth.models import AbstractUser
# Create your models here.
class Userinfo(AbstractUser):
phone = models.BigIntegerField(null=True)
avatar = models.FileField(upload_to='avatar/',default='static/img/default.jpg')
# 该字段你直接传文件即可 会自动将文件保存到avatar文件夹下 然后数据库里面存文件路径

class Blog(models.Model):
site_name = models.CharField(max_length=32)

# 该字段存的是用户自己写的css文件路径l

--》创建bbs 数据库 __init__ 导入:pymysql.install
--->settings内倒入 : AUTH_USER_MODEL = 'app.类名'
