path('student_list/', views.student_list),
3.RuntimeError: Model class APP.models.Test doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.
解决：依赖不到，需要在INSTALLED_APPS = ['myAppName.apps.myAppNameConfig',] 加上
这myAppNameConfig是命令在 apps.py 中生成的默认类.manage.py createapp myAppName。myAppName您的应用程序的名称在哪里。
4.django.db.utils.ProgrammingError: (1146, "Table 'autooffice.app_test' doesn't exist")

python3 manage.py makemigrations APP
python3 manage.py migrate
完成后，刷新数据库会看见 APP_test的
5.Django post 请求返回 403
解决：导入from django.views.decorators.csrf import csrf_exempt
在函数前面添加修饰器：@csrf_exempt
例：
@csrf_exempt
def runoob(request):
name = request.POST.get("name")
