DATABASES = {
    'default': {
    'ENGINE': 'django.db.backends.mysql',
    'NAME':'test',
    'USER': 'root',
    'PASSWORD': 'root',
    'HOST': '127.0.0.1',
    'PORT': '3307',
    }
}

Django基本的增删改查:

def depart(request):
    # ORM操作
    # 新增
    #models.Department.objects.create(title="销售部",count=10)
    #models.Department.objects.create(**{"title":"销售部","count":0})
​
    #查询
    #queryset=models.Department.objects.all()
    #queryset=models.Department.objects.filter(id__gt=1)#id>1
    # for obj in queryset:
    #     print(obj.id,obj.title,obj.count)
    #obj=models.Department.objects.filter(id=1).first()
    #print(obj.id,obj.title,obj.count)
​
    #删除
    #models.Department.objects.filter(id=1).delete()
​
    #更新
    models.Department.objects.filter(id=2).update(count=100)
    return HttpResponse("执行成功")
