cmdb资产管理2

新增资产

现在api服务端已经能获取到我们要做的操作了。接下来应该是补充获取操作后对应的程序编写

我们要做的是把post请求发过来的数据保存到数据库。我们创建repository 名字的app，并设计models创建表来存储数据。后面可以从数据库获取信息并展示出来

models.py

我们可以将业务线先设置成这个。然后执行命令生成表

我们先将cert删除，并且将这里写入文件的注释掉，这样每次判断都是新增主机了

服务端接收的数据如下图，将它存入数据库

我们要将新增的这些资产信息存入数据库

先看新增server，1处有默认，2处可以为空，我们先不管

我们先看这三种硬件信息

而这三种硬件信息和我们传过来的数据一致，字段名字也一样

我们将数据字典取出来，然后update到同一个字典中，合成一个。

获得如下的字典

{
    'os_platform': 'linux',
    'os_version': '6.5',
    'hostname': 'c1.com',
    'manufacturer': 'Parallels Software International Inc.',

    'sn': 'Parallels-1A 1B CB 3B 64 66 4B 13 86 B0 86 FF 7E 2B 20 30',
