1.创建django项目：
命令：django-admin.py startproject todoManager
2.在此项目下创建apps应用
命令：python manage.py startapp apps
目录如下：
3.打开todoManager/todoManager/settings.py文件，将应用添加进去：
4.打开todoManager/todoManager/settings.py文件，设置连接数据库，以下连接的是MYSQL
5.打开todoManager/apps/models.py文件，添加如下内容，创建数据库，创建User表，用户名和密码两个字段。
6.进行数据库的同步：
查看django版本：输入python ，enter;import django django.get_version()
我的版本是1.9之前的：在Django1.9之前，数据库同步只需要一条命令，那就是python manage.py syncdb
后生成的 apps_user 表就是我们models.py 中所创建的User类。
7. 配置URL
7.1 打开todoManager/todoManager/urls.py
7.2 在todoManager/apps/目录下创建urls.py文件：
from django.conf.urls import patterns, url,include
from django.contrib import admin
from apps import views
urlpatterns = patterns(‘‘,
url(r‘^regist/$‘,views.regist,name = ‘regist‘),
url(r‘^login/$‘,views.login,name = ‘login‘),
url(r‘^index/$‘,views.index,name = ‘index‘),
url(r‘^logout/$‘,views.logout,name = ‘logout‘),
)
7.3 创建视图
打开todoManager/apps/views.py 文件：
# -*- coding: utf-8 -*-
from django.shortcuts import render
# Create your views here.
#coding=utf-8
from django.shortcuts import render,render_to_response
from django.http import HttpResponse,HttpResponseRedirect
from django.template import RequestContext
from django import forms
from apps.models import User
from pymongo import MongoClient
from django.views.decorators.csrf import csrf_protect, csrf_exempt
mongo_client = MongoClient(‘192.168.86.126‘, 27017)
#表单
class UserForm(forms.Form):
username = forms.CharField(label=u‘用户名‘,max_length=100)
password = forms.CharField(label=u‘密 码‘,widget=forms.PasswordInput())
#注册
# @csrf_protect
def regist(req):
if req.method == ‘POST‘:
uf = UserForm(req.POST)
if uf.is_valid():
#获得表单数据
username = uf.cleaned_data[‘username‘]
password = uf.cleaned_data[‘password‘]
#添加到数据库
User.objects.create(username= username,password=password)
return HttpResponse(‘regist success!!‘)
else:
uf = UserForm()
return render_to_response(‘regist.html‘,{‘uf‘:uf}, context_instance=RequestContext(req))
#登陆
# @csrf_protect
def login(req):
username = req.COOKIES.get(‘username‘,‘‘)
if req.method == ‘POST‘:
uf = UserForm(req.POST)
if uf.is_valid():
#获取表单用户密码
username = uf.cleaned_data[‘username‘]
password = uf.cleaned_data[‘password‘]
#获取的表单数据与数据库进行比较
user = User.objects.filter(username__exact = username,password__exact = password)
if user:
#比较成功，跳转index
response = HttpResponseRedirect(‘/apps/index/‘)
#将username写入浏览器cookie,失效时间为3600
response.set_cookie(‘username‘,username,3600)
return response
else:
#比较失败，还在login
return HttpResponseRedirect(‘/apps/login/‘)
else:
uf = UserForm()
return render_to_response(‘login.html‘,{‘uf‘:uf}, context_instance=RequestContext(req) )
#登陆成功
# @csrf_protect
def index(req):
username = req.COOKIES.get(‘username‘,‘‘)
if username:
key_words_coll = mongo_client[‘yidong_zixun‘][‘key_words‘]
categorys = {}
tasks = {}
results = key_words_coll.find().batch_size(30)
for result in results:
category_id = result["category_id"]
category_name = result["category_name"]
_id = result["_id"]
name = result["name"]
if not categorys.has_key(category_id):
categorys[category_id] = category_name
if not tasks.has_key(category_id):
tasks[category_id] = []
tasks[category_id].append({"task_id":_id,"name":name})
else:
tasks[category_id].append({"task_id":_id,"name":name})
return render_to_response(‘index.html‘ ,{‘username‘:username,‘categorys‘:categorys,"tasks":tasks}, context_instance=RequestContext(req))
else:
return HttpResponseRedirect(‘/apps/login/‘)
#退出
# @csrf_protect
def logout(req):
# response = HttpResponse(‘logout !!‘)
response = HttpResponseRedirect(‘/apps/login/‘)
response.delete_cookie(‘username‘)
return response
7.4 创建模板
先在todoManager/apps/目录下创建templates目录，接着在todoManager/apps/templates/目录下创建base.html、regist.html、login.html 、index.html 文件：
7.5设置模板路径
打开todoManager/todoManager/settings.py文件，在底部添加：
8.运行django
命令：python manage.py runserver 0.0.0.0:8000
