1.整理web框架推导思路
2.安装django并正常启动访问，测试三板斧
3.整理今日日考题，django内容
选做题
1.结合前端，django，MySQL，pymysql模块实现数据库数据动态展示到前端
目录：
settings.py:app01注册
# 注册的app(app就是功能模块) INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'app01.apps.App01Config', ]
urls.py:添加路由
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), # 写我们自己的路由与视图函数对应关系,这里我们可以根据功能的不同执行不同的app下面的views url(r'^index/', views.index), url(r'^get_user/', views.get_user), url(r'^test/', views.test), ]
views.py:添加视图函数
from django.shortcuts import render,HttpResponse,redirect import pymysql # Create your views here. # /index def index(request): """ :param request: 请求相关的所有数据，比之前用wsgrief模块实现传给函数的env大字典更厉害，request这是个对象 :return: """ # return HttpResponse("你好啊，我是Django") return render(request,"index.html") #自动你去templates文件夹下帮你查找文件 # 动态获取用户信息 def get_user(request): # 去数据库中获取数据,传递给html页面，借助于模板语法 发送给浏览器 # 链接 conn = pymysql.connect( host='127.0.0.1', port=3306, user='root', password='123456', database='atm_db', charset='utf8', # autocommit=True # 自动提交 ) # 游标 cursor = conn.cursor(cursor=pymysql.cursors.DictCursor) # 执行完毕返回的结果集以字典显示 # 执行sql语句 sql = 'select * from userinfo' rows = cursor.execute(sql) # 执行sql语句，返回sql查询成功的记录数目 # 获取数据： data_list = cursor.fetchall() # [{},{},,,,]列表套字典格式 cursor.close() conn.close() return render(request,"userinfo.html",{"user_data":data_list}) #语法测试 def test(request): views_list = ["a", "b", "c", "d", "e"] return render(request,"Grammar_test.html",{"data_list":views_list})
userinfo.html

2.尝试着摸索django模版语法
