上节内容回顾：
    1、Django请求生命周期
        -> URL对应关系（匹配） -> 视图函数 -> 返回用户字符串
        -> URL对应关系（匹配） -> 视图函数 -> 打开一个HTML文件，读取内容
    2、创建django projcet
        django-admin startproject mysite
        ..
        mysite
            mysite
                - 配置文件
                - url.py
                - settings.py
 
        cd mysite
        python manage.py startapp cmdb
        mysite
            mysite
                - 配置文件
                - urls.py
                - settings.py
            cmdb
                - views.py
                - admin.py
                - models.py # 创建数据库表
    3、配置
        模板路径
        静态文件路径
        # CSRF
    4、编写程序
        a. url.py
            /index/    ->   func
        b. views.py
            def func(request):
                # 包含所有的请求数据
                ...  ---业务处理
                return HttpResponse('字符串')
                return render(request, 'index.html', {''})
                retrun redirect('URL')
        c. 模板语言
            return render(request, 'index.html', {'li': [11,22,33]})
            {% for item in li %}
                <h1>{{item}}</h1>
            {% endfor %}
            ***********  索引用点 **********
            <h2> {{item.0 }} </h2>
一、路由系统，URL
    1、url(r'^index/', views.index),
       url(r'^home/', views.Home.as_view()),
    2、url(r'^detail-(\d+).html', views.detail),
    3、url(r'^detail-(?P<nid>\d+)-(?P<uid>\d+).html', views.detail)    #推荐使用
       PS:
            def detail(request, *args,**kwargs):
                pass
       实战：
            a.
                url(r'^detail-(\d+)-(\d+).html', views.detail),
                def func(request, nid, uid):   #id是内置函数，不要用
                    pass
                def func(request, *args):
                    args = (2,9)
                def func(request, *args, **kwargs):
                    args = (2,9)
            b.
                url(r'^detail-(?P<nid>\d+)-(?P<uid>\d+).html', views.detail)
                def func(request, nid, uid):
                    pass
                def funct(request, **kwargs):
                    kwargs = {'nid': 1, 'uid': 3}
                def func(request, *args, **kwargs):
                    kwargs = {'nid': 1, 'uid': 3}
    4、 name
        对URL路由关系进行命名， ***** 以后可以根据此名称生成自己想要的URL *****
       在urls里
        url(r'^asdfasdfasdf/', views.index, name='i1'),
        url(r'^yug/(\d+)/(\d+)/', views.index, name='i2'),
        url(r'^buy/(?P<pid>\d+)/(?P<nid>\d+)/', views.index, name='i3'),
       在views里
        def func(request, *args, **kwargs):
            from django.urls import reverse
            url1 = reverse('i1')                              # asdfasdfasdf/
            url2 = reverse('i2', args=(1,2,))                 # yug/1/2/
            url3 = reverse('i3', kwargs={'pid': 1, "nid": 9}) # buy/1/9/
        xxx.html（在模板语言里）
            {% url "i1" %}               # asdfasdfasdf/
            {% url "i2" 1 2 %}           # yug/1/2/  #指定页面
            {% url "i3" pid=1 nid=9 %}   # buy/1/9/
        注：
            # 当前的URL
            request.path_info
    5、多级路由
        project/urls.py
            from django.conf.urls import url,include
            from django.contrib import admin
            urlpatterns = [
                url(r'^cmdb/', include("app01.urls")),
                url(r'^monitor/', include("app02.urls")),
            ]
        app01/urls.py
            from django.conf.urls import url,include
            from django.contrib import admin
            from app01 import views
            urlpatterns = [
                url(r'^login/', views.login),
            ]
        app02/urls.py
            from django.conf.urls import url,include
            from django.contrib import admin
            from app02 import views
            urlpatterns = [
                url(r'^login/', views.login),
            ]
    6、默认值（欠）
    7、命名空间（欠）
二、视图
    1、获取用户请求数据
        request.GET
        request.POST
        request.FILES
        PS:
            GET:获取数据
            POST:提交数据
    2、checkbox等多选的内容
        request.POST.getlist()
    3、上传文件
        # 上传文件,form标签做特殊设置
        obj = request.FILES.get('fafafa')
        obj.name
        f = open(obj.name, mode='wb')
        for item in obj.chunks():
            f.write(item)
        f.close()
    4、FBV & CBV（class）
       function base view
        url.py
            index -> 函数名
        view.py
            def 函数(request):
                ...
        ====》
        /index/ -> 函数名
        /index/ -> 类
        ====》
        建议：两者都用
    5、装饰器
        欠
三、模板
四、ORM操作
            1、db first 先登录数据库写sql语句创建表结构，工具（如python）连接后自动在本地生成类，
                        以后不用写sql语句，根据类就能操作数据库
            2、code first 先写代码（类），类再生成数据库表（主流都是code first 如sqlalchemy，Django等）
    select * from tb where id > 1
    # 对应关系
    models.tb.objects.filter(id__gt=1)
    models.tb.objects.filter(id=1)
    models.tb.objects.filter(id__lt=1)
    创建类
    a. 先写类
        from django.db import models
        # app01_userinfo
        class UserInfo(models.Model):
            # id列，自增，主键
            # 用户名列，字符串类型，指定长度
            username = models.CharField(max_length=32)
            password = models.CharField(max_length=64)
    b. 在settings里注册APP
        INSTALLED_APPS = [
            'django.contrib.admin',
            'django.contrib.auth',
            'django.contrib.contenttypes',
            'django.contrib.sessions',
            'django.contrib.messages',
            'django.contrib.staticfiles',
            'app01',
        ]
    c. 执行命令
        python manage.py  makemigrations
        python manage.py  migrate
    d. ********** 注意 ***********
        Django默认使用MySQLdb模块链接MySQL
        主动修改为pymysql，在project同名文件夹下的__init__文件中添加如下代码即可：
            import pymysql
            pymysql.install_as_MySQLdb()
    1. 根据类自动创建数据库表
        # app下的models.py
        python manage.py  makemigrations
        python manage.py  migrate
        字段：
            字符串类型
            数字
            时间
            二进制
            自增（primary_key=True）
        字段的参数：
            null               -> db是否可以为空
            default            -> 默认值
            primary_key        -> 主键
            db_column          -> 列名
            db_index           -> 索引
            unique               -> 唯一索引
            unique_for_date    ->
            unique_for_month
            unique_for_year
            auto_now           -> 创建时，自动生成时间
            auto_now_add       -> 更新时，自动更新为当前时间
                # obj = UserGroup.objects.filter(id=1).update(caption='CEO')
                # obj = UserGroup.objects.filter(id=1).first()
                # obj.caption = "CEO"
                # obj.save()
            choices              -> django admin中显示下拉框，避免连表查询（因为效率低）
            blank             -> django admin是否可以为空
            verbose_name      -> django admin显示字段中文
            editable          -> django admin是否可以被编辑
            error_messages    -> 错误信息欠
            help_text         -> django admin提示
            validators          -> django form ,自定义错误信息（欠）
            创建 Django 用户：python manage.py createsuperuser
                更多http://www.cnblogs.com/wupeiqi/articles/5246483.html
    2. 根据类对数据库表中的数据进行各种操作
        一对多：
            a. 外键
            b.
                外键字段_id
            c.
                models.tb.object.create(name='root', user_group_id=1)
            d.
                userlist = models.tb.object.all()
                for row in userlist:
                    row.id
                    row.user_group_id
                    row.user_group.caption    #跨表操作
    =================== 作业：用户管理 ====================
    1、用户组的增删改查
    2、用户增删改查
        - 添加必须是模态对话框
        - 删除必须是模态对话框
        - 修改，必须显示默认值（可以用if-else判断）
    3、比较好看的页面
    4、预习：

 """s14day19_2 URL Configuration
 
 The `urlpatterns` list routes URLs to views. For more information please see:
     https://docs.djangoproject.com/en/1.10/topics/http/urls/
 Examples:
 Function views
     1. Add an import:  from my_app import views
     2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
 Class-based views
     1. Add an import:  from other_app.views import Home
     2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
 Including another URLconf
     1. Import the include() function: from django.conf.urls import url, include
