arya 项目
01
（主要学习reverse方法，逆向解析url）
一、项目结构(只列出使用的文件)
-
learnmodelform 项目目录
-
app01 第一个app
model.py 数据库文件
arya.py 引用插件
-
arya 第二个app
apps.py 加载自动搜索模块，django启动时自动搜索该我文件配置的模块
-
service arya逻辑文件目录
v1.py 逻辑代码文件，主要用来配置url，table表单展示数据，数据库操作等
-
learnmodelform
settings.py 配置文件
urls.py 路由文件
-
templates 模板文件
model.py代码:
from
django.db
import
models
# Create your models here.
class
Role(models.Model):
caption

models.CharField(max_length

def

else
