简单的一个列表展示，实现了增、删、插
1.通过新建项目来创建一个Django项目
2.通过pycharm中的Terminal来创建app ，命令如下：
python manage.py startapp devicesys
最后项目结构如下：
项目结构：
3.修改相关配置：
在于项目同名的文件夹下打开setting.py 做两个事情（1）注释MIDDLEWARE中的 # 'django.middleware.csrf.CsrfViewMiddleware', （2） 在文件结尾处增加STATICFILES_DIRS = [( os.path.join(BASE_DIR,"static"))]
打开urls.py将devicesys导入进来
4.在devicesys文件夹下的models.py中编写如下代码
from django.db import models
import sqlalchemy
from sqlalchemy import create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column,Integer,DATE,ForeignKey,String
from sqlalchemy.orm import sessionmaker,relationship
# Create your models here. # 创建数据库连接
engine = create_engine("mysql+pymysql://root:root@localhost/testuser?charset=utf8",echo=True) # 生成orm基类
Base = declarative_base() # 创建表映射
class Devices(Base):
__tablename__ = "devices" # 表名称
id = Column(Integer,primary_key=True)
name = Column(String(64)) # 设备名称
ip = Column(String(32)) # 设备地址
username = Column(String(32)) # 设备账号
password = Column(String(32)) # 设备密码
brand = Column(String(32)) # 设备品牌
addtime = Column(DATE) # 设备添加时间 # 构建表结构
Base.metadata.create_all(engine) # 创建数据库会话类
session_class = sessionmaker(bind=engine)
# 创建数据库会话实例
session = session_class() def getlist():
return session.query(Devices).filter_by().all() def add(name,ip,username,password,brand):
temp = Devices(name=name,ip=ip,username=username,password=password,brand=brand)
session.add_all([temp])
session.commit()
def delete(del_id):
del_info = session.query(Devices).filter(Devices.id==del_id).first()
if del_info is not None:
session.delete(del_info)
session.commit()
在views.py中编写如下代码：
from django.shortcuts import render # Create your views here.
from django.shortcuts import HttpResponse
from django.shortcuts import render
from django.shortcuts import redirect
from devicesys import models
import time
def loadlist(request):
list = models.getlist()
print(list)
return render(request,"index.html",{"list":list}) def add(request):
if request.method == "POST":
# 获取提交信息
name = request.POST.get("name")
ip = request.POST.get("ip")
username = request.POST.get("username")
password = request.POST.get("password")
brand = request.POST.get("brand")
# 获取当前时间并进行格式化
# addtime = time.strftime("%Y-%m-%d", time.time())
models.add(name,ip,username,password,brand)
list = models.getlist()
return render(request, "index.html", {"list": list}) def delete(request):
if request.method == "POST":
# 获取参数
del_id = request.POST.get("del_id")
if del_id:
models.delete(del_id)
list = models.getlist()
return render(request, "index.html", {"list": list})
else:
return HttpResponse("<h1>404</h1>")
5.在项目下创建static文件夹并且将layer相关文件导入进去，并且导入jquery.js
6.在templates文件夹下新建index.html
