【python学习笔记：Django】7.数据库模型浅析

Django的模型(数据库)

• 模型概述
  

• 在vscode下新建终端，注意python虚拟环境是否激活；

  建立Django工程Week3;

  在Week3下建立应用sqliteExp

• setting.py配置
  

• models.py

  from django.db import models
  
  class BaseInfo(models.Model):
      studentId=models.CharField(max_length=50,primary_key=True)
      name = models.CharField(max_length=30)
      age = models.IntegerField()
  
  
  class Hobby(models.Model):
      hobbyId = models.IntegerField(primary_key=True)
      hobby=models.CharField(max_length=50)
      student=models.ForeignKey(BaseInfo,on_delete=models.CASCADE)
  

• 导入模板
  

• views.py

  from django.shortcuts import render,HttpResponse
  from sqlite3Exp.models import BaseInfo
  
  def AddStudent(request):
      id = request.GET['id']
      name = request.GET['name']
      age = request.GET['age']
  
      info = BaseInfo(studentId=id,name=name,age=age)
      info.save()
      
      return  HttpResponse("Adding is successful")
  

• urls.py

  from django.contrib import admin
  from django.urls import path
  from sqlite3Exp import views
  
  urlpatterns = [
      path('admin/', admin.site.urls),
      path('info/',views.AddStudent),
  ]
