【django】 model_to_dict ‘QuerySet‘ object has no attribute ‘_meta‘_queryset' object has no attribute 'meta

# 设置预约信息页面
def admin_setting_booking_info(request):
    system_configurations = SystemConfiguration.objects.filter(configuration_name='allow_booking_date_start')
    context = model_to_dict(system_configurations)
    return render(request, './adminWeb/setting_booking_info.html', context)

 上面的代码filter查询之后会返回多条数据，使用model_to_dict会报错

'QuerySet' object has no attribute '_meta'

这是因为对象列表没有'_meta'属性

单独的对象才有, 忘记加first了

edit_obj = models.Role.objects.filter(pk=edit_id).first()

如果我们还是需要返回多条数据，可以先遍历，单独处理

# 设置预约信息页面
def admin_setting_booking_info(request):
    system_configurations = SystemConfiguration.objects.filter(configuration_name='allow_booking_date_start')
    for system_configuration in system_configurations:
        context = model_to_dict(system_configuration)
        print(context)
