篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Django的cmdb探索与开发相关的知识，希望对你有一定的参考价值。
经过上次对itchat调用zabbixAPI的研究之后对python的兴趣一发不可收拾，近期上面要求研究一下cmdb，于是自己做了一个简单的cmdb系统 。对其实踩坑的地方做一些记录，由于之前对于前端的知识也是一窍不通，所以很多问题可能也比较初级。
环境：python 3.6.5 ，django 1.8.16。前端模板是网上找到的，希望通过这次研究在前端js/ajax/css上也能有所提升。
1、项目目录，页面存在templates
2、settings.py设置，还是注意下Setting的配置。当时STATICFILES_DIRS字段少写了一个“s”加载不了静态，排错排了一天。

2、关于，model,这里就只贴devices和select下拉框的代码了。
class BaseModel(models.Model):
delete_flag = models.CharField(max_length=4, verbose_name="删除标志")
class Devices(BaseModel): sn = models.CharField(max_length=32, verbose_name="序列号") Psn = models.CharField(max_length=32,verbose_name="资产编号") DataRoomID = models.IntegerField(verbose_name="机房ID") CabinetID = models.IntegerField(verbose_name="机柜ID") deviceType = models.IntegerField(verbose_name="设备类型")#1、网络设备 2、安全设备 3、服务器 4、虚拟机 deviceMap = models.CharField(max_length=32, verbose_name="设备位置") company = models.CharField(max_length=32, verbose_name="设备品牌") model = models.CharField(max_length=32, verbose_name="设备型号") adminIP = models.CharField(max_length=32, verbose_name="管理IP") produceIP = models.CharField(max_length=32, verbose_name="业务IP") system = models.CharField(max_length=32, verbose_name="操作系统") uplinkdev = models.CharField(max_length=32, verbose_name="上联设备SN") downlinkdev = models.CharField(max_length=32, verbose_name="下联设备SN") lastLogin = models.DateField(verbose_name="更新时间") deviceUser = models.CharField(max_length=32,verbose_name="设备使用人") lastLoginUser = models.IntegerField(verbose_name="操作员ID") deviceDes = models.CharField(max_length=64, verbose_name="设备描述") DataRoom = models.CharField(max_length=32, verbose_name="机房位置") Uplinkport = models.CharField(max_length=32,verbose_name="上联口") Downlinkport = models.CharField(max_length=32, verbose_name="下联口") Memory = models.CharField(max_length=32, verbose_name="内存占用率") Cpu = models.CharField(max_length=32, verbose_name="cpu占用率") Disk = models.CharField(max_length=32, verbose_name="磁盘占用率") isVirtual = models.CharField(max_length=32, verbose_name="是否虚拟化") isActive = models.CharField(max_length=32,verbose_name="是否上线") isNomal = models.CharField(max_length=32,verbose_name="状态是否正常")
class ImportForm(forms.Form): Device_type_list = ( (1, "服务器"), (2, "网络设备"), (3, "安全设备"), (4, "虚拟机"), (5, "交换机") ) #固定下拉选项，Device_type为post值，widget为下拉内容，下同。 device_type = forms.IntegerField( widget = forms.Select(choices=Device_type_list) ) #动态不定下拉选项 Dataroom_list = forms.IntegerField( widget=forms.Select() ) def __init__(self,*args,**kwargs): super(ImportForm,self).__init__(*args,**kwargs) #查询数据库获取下拉内容，根据主键basemodel_ptr_id查询获取name字段。并赋值给选项 self.fields[‘Dataroom_list‘].widget.choices = Dataroom.objects.all().values_list(‘basemodel_ptr_id‘,‘name‘)
3、关于views
这部分涉及到功能。下一部分详细记录。
