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

from django.db import models   class BusinessUnit(models.Model):     """     业务线     """     name = models.CharField('业务线', max_length=64, unique=True)      class Meta:         verbose_name_plural = "业务线表"      def __str__(self):         return self.name   class IDC(models.Model):     """     机房信息     """     name = models.CharField('机房', max_length=32)     floor = models.IntegerField('楼层', default=1)      class Meta:         verbose_name_plural = "机房表"      def __str__(self):         return self.name   class Server(models.Model):     """     服务器信息 主机     """      device_status_choices = (         (1, '上架'),         (2, '在线'),         (3, '离线'),         (4, '下架'),     )     device_status_id = models.IntegerField('设备状态', choices=device_status_choices, default=1)      idc = models.ForeignKey('IDC', verbose_name='IDC机房', null=True, blank=True, on_delete=models.CASCADE)     cabinet_num = models.CharField('机柜号', max_length=30, null=True, blank=True)     cabinet_order = models.CharField('机柜中序号', max_length=30, null=True, blank=True)      business_unit = models.ForeignKey('BusinessUnit', verbose_name='属于的业务线', null=True, blank=True,                                       on_delete=models.CASCADE)      # 基本信息 + 主板信息 + CPU信息     hostname = models.CharField('主机名', max_length=128, unique=True)     os_platform = models.CharField('系统', max_length=16, null=True, blank=True)     os_version = models.CharField('系统版本', max_length=16, null=True, blank=True)      sn = models.CharField('SN号', max_length=64, db_index=True)     manufacturer = models.CharField(verbose_name='制造商', max_length=64, null=True, blank=True)     model = models.CharField('型号', max_length=64, null=True, blank=True)      cpu_count = models.IntegerField('CPU个数', null=True, blank=True)     cpu_physical_count = models.IntegerField('CPU物理个数', null=True, blank=True)     cpu_model = models.CharField('CPU型号', max_length=128, null=True, blank=True)      latest_date = models.DateField('最后更新时间', null=True)     create_at = models.DateTimeField(auto_now_add=True, blank=True)      class Meta:         verbose_name_plural = "服务器表"      def __str__(self):         return self.hostname   class Disk(models.Model):     """     硬盘信息     """     slot = models.CharField('插槽位', max_length=8)     model = models.CharField('磁盘型号', max_length=108)     capacity = models.FloatField('磁盘容量GB')     pd_type = models.CharField('磁盘类型', max_length=32)      server = models.ForeignKey(verbose_name='服务器', to='Server', related_name='disk_list', on_delete=models.CASCADE)      class Meta:         verbose_name_plural = "硬盘表"      def __str__(self):         return self.slot   class NIC(models.Model):     """     网卡信息     """     name = models.CharField('网卡名称', max_length=128)     hwaddr = models.CharField('网卡mac地址', max_length=64)     netmask = models.CharField(max_length=64)     ipaddrs = models.CharField('ip地址', max_length=256)     up = models.BooleanField(default=False)     server = models.ForeignKey('Server', related_name='nic_list', on_delete=models.CASCADE)      class Meta:         verbose_name_plural = "网卡表"      def __str__(self):         return self.name   class Memory(models.Model):     """     内存信息     """     slot = models.CharField('插槽位', max_length=32)     manufacturer = models.CharField('制造商', max_length=32, null=True, blank=True)     model = models.CharField('型号', max_length=64)     capacity = models.FloatField('容量', null=True, blank=True)     sn = models.CharField('内存SN号', max_length=64, null=True, blank=True)     speed = models.CharField('速度', max_length=16, null=True, blank=True)      server = models.ForeignKey('Server', related_name='memory_list', on_delete=models.CASCADE)      class Meta:         verbose_name_plural = "内存表"      def __str__(self):         return self.slot   class AssetRecord(models.Model):     """     资产变更记录     """     server = models.ForeignKey('Server', related_name='servers', on_delete=models.CASCADE)     content = models.TextField(null=True)     create_at = models.DateTimeField(auto_now_add=True)      class Meta:         verbose_name_plural = "资产记录表"   class ErrorLog(models.Model):     """     错误日志,如：agent采集数据错误 或 运行错误     """     server = models.ForeignKey('Server', null=True, blank=True, on_delete=models.CASCADE)     title = models.CharField(max_length=16)     content = models.TextField()     create_at = models.DateTimeField(auto_now_add=True)      class Meta:         verbose_name_plural = "错误日志表"      def __str__(self):         return self.title

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.',     'model': 'Parallels Virtual Platform',     'sn': 'Parallels-1A 1B CB 3B 64 66 4B 13 86 B0 86 FF 7E 2B 20 30',     'cpu_count': 24,     'cpu_physical_count': 2,     'cpu_model': ' Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz' }
