simple-todo: 一个简易的 todo 程序 - django版
今天无意间看到 simple-todo: 一个简易的 todo 程序 - web.py 中文教程 ，然后发现竟然有好多的版本 http://simple-is-better.com/news/tag/simple-todo
然后看到django版的是个半成品，好吧，自己动手丰衣足食。
django 安装配置这里就不再介绍了，直接给之前的地址： django 简易博客开发 1 安装、创建、配置、admin使用
使用的环境： fedora 17 + django1.4 + python2.7 + sqlite3
前端使用的 bootstrap + jquery
实现添加修改删除 ajax支持 可自行添加用户控制
1、django安装 project 创建 、app 创建、安装、admin使用
看着个吧，这篇博客有详细教程
2、上代码
#!/usr/bin/python
# -*- coding: utf-8 -*-
from django.db import models
from django_openid_auth.models import User
#之前我用过openid 这里换成 from django.contrib.auth.models import User 就可以了
class Todo(models.Model):
user = models.ForeignKey(User)
todo = models.CharField(max_length=50)
flag = models.CharField(max_length=2， default='1')
priority = models.CharField(max_length=2， default='0')
pubtime = models.DateTimeField(auto_now_add=True)
def __unicode__(self):
return u'%d %s %s' % (self.id, self.todo, self.flag)
class Meta:
ordering = ['priority', 'pubtime']
priority 为优先级 排序时优先级高的在前面，越小优先级越高；然后再按时间排序，越早越靠前
flag 标记是否完成 默认为1表示未完成
当然这两处改为models.IntegerField 更好一些，可以自己修改一下
创建数据库:
python manage.py syncdb
在admin查看
#!/usr/bin/python
# -*- coding: utf-8 -*-
from django.contrib import admin
from simpleToDo.models import Todo
class TodoAdmin(admin.ModelAdmin):
list_display = ('user', 'todo', 'priority', 'flag', 'pubtime')
list_filter = ('pubtime',)
ordering = ('-pubtime',)
admin.site.register(Todo, TodoAdmin)
urls.py
#!/usr/bin/python
# -*- coding: utf-8 -*-
from django.conf.urls import *
urlpatterns = patterns(('simpleToDo.views'),

76 user = User.objects.get(id='1')
77 todo = Todo(user=user, todo=atodo, priority=priority, flag='1')
78 todo.save()

81 return render_to_response('simpleTodo.html',

83 context_instance=RequestContext(request))
84 else:
85 try:
86 todo = Todo.objects.get(id=id)
87 except Exception:
88 raise Http404
89 return render_to_response('updatatodo.html', {'todo': todo},
90 context_instance=RequestContext(request))
因为表单使用的是post方法，所以每个view 后都添加了 context_instance=RequestContext(request)
否则可能会出现这个错误

1、首页
2、添加事项页面
3、修改事项时页面
