1.多表与基表概念 2.多表断关联关系分析 3.多表序列化组件 4.自定义序列化深度连表查询 5.多表反序列化组件 6.序列化反序列化整合（重点） 7.群增接口实现 8.单删群删接口实现 课程准备：配置settings.py 1 INSTALLED_APPS = [ 2 # ... 3 'rest_framework', 4 ] 5 6 DATABASES = { 7 'default': { 8 'ENGINE': 'django.db.backends.mysql', 9 'NAME': 'dg_proj', 10 'USER': 'root', 11 'PASSWORD': '123', 12 } 13 } 14 """ 15 任何__init__文件 16 import pymysql 17 pymysql.install_as_MySQLdb() 18 """ 19 20 LANGUAGE_CODE = 'zh-hans' 21 TIME_ZONE = 'Asia/Shanghai' 22 USE_I18N = True 23 USE_L10N = True 24 USE_TZ = False 25 26 MEDIA_URL = '/media/' 27 MEDIA_ROOT = os.path.join(BASE_DIR, 'media') 代码 路由： 1 # 主 2

搭建前奏 打开pycharm,建立day71的程序，如图 项目建好以后在settings里面进行简单配置，如图所示 然后简单地进行数据库的配置： 接下来再在settings里面注册，如图： 配置文件完成后再做一个路由分发，如图： 接下来在总路由中进行路由分发与查找照片的相应配置，如图： 再下来就是在__init__中进行连接数据库的相应配置，如图 接着在settings进行全局配置，看图 基础的结构配置已完成，接下来在models里面进行表的创建，如图：创建表所需的字段 先创建一个基表，基表 : 基表的class Mate一定要加上abstract = True,因为该表是提供共有字段的，不是用来创表的 如果创建表就要继承我，如果不想增加新的字段就继承我就行，若果想加新的字段，就在我的基础上增加新的字段。 还有提一个就是模型类的封装就是共有类的封装，依据是abstract的Meta里面规定的 # 所有的东西都来自于models.Model class BaseModel(models.Model): is_delete = models.BooleanField(default=0) create_time = models.DateTimeField(auto_now_add=True)　　# 作为基表的Model不能在数据库中形成对应的表 　　　class Meta:　　　　　

一.序列化组件主要知识点 Serializer（偏底层）、ModelSerializer（重点）、ListModelSerializer（辅助群改） 二.Serializer组件 序列化准备： 模型层：models.py class User(models.Model): SEX_CHOICES = [ [0, '男'], [1, '女'], ] name = models.CharField(max_length=64) pwd = models.CharField(max_length=32) phone = models.CharField(max_length=11, null=True, default=None) sex = models.IntegerField(choices=SEX_CHOICES, default=0) icon = models.ImageField(upload_to='icon', default='icon/default.jpg') class Meta: db_table = 'old_boy_user' verbose_name = '用户' verbose_name_plural = verbose_name def __str__(self): return '%s' % self.name 后台管理层：admin.py

I want publish my app in the android market. How much time does it take to make an android developer account verified by google. also what other things I should do ? Google has an extensive guide on the steps to take an the things you need to publish your application on the market: Preparing to publish: http://developer.android.com/guide/publishing/preparing.html Publishing on Android market: http://developer.android.com/guide/publishing/publishing.html After paying for the developer account, it takes less than a day to get approved. In my experience, when you have prepared everything, the
