Django简单的todo练习
刚刚看完django book，网上找了些例子来练习最基本的操作：
python2.7.3
django1.6.2
mysql5.5
前端套用bootstrap
models.py
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
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
admin.py
from django.contrib import admin
# Register your models here.
from todoApp.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
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
from todoApp import views
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'simpleTodo.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^admin/', include(admin.site.urls)),
url(r'^$', views.todolist, name='todo'),
url(r'^addtodo/$', views.addtodo, name='add'),
url(r'^todofinish/(?P<id>\d+)/$', views.todofinish, name='finish'),
url(r'^todobackout/(?P<id>\d+)/$', views.todoback, name='backout'),
url(r'^updatetodo/(?P<id>\d+)/$', views.updatetodo, name='update'),
url(r'^tododelete/(?P<id>\d+)/$', views.tododelete, name='delete'),
)
