这篇文章主要介绍基于Django的Admin后台如何实现定制简单监控页，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
我们使用Django的Admin二次定制一个图形化界面,首先我们把语言设置为中文简体.
修改: settings.pyLANGUAGE_CODE = 'zh-hans'TIME_ZONE = 'Asia/Shanghai'修改: apps.pyfrom django.apps import AppConfigclass MywebConfig(AppConfig): name = 'MyWeb' verbose_name = "服务器参数收集"接着我们来定义models.py数据库模型,定义基本的数据查询.
from django.db import modelsfrom django.utils.html import format_htmlimport datetimeSTATUS_CHOICES = (('d', '在用设备'), ('p', '下线设备'), ('w', '损坏设备'),)# 定义主机基本信息表class HostInfoDB(models.Model): id = models.AutoField(primary_key=True) # HostAddr = models.TextField(max_length=128,verbose_name="主机地址") HostAddr = models.CharField(max_length=128, verbose_name="主机地址") HostName = models.CharField(max_length=128, verbose_name="主机名称") HostType = models.CharField(max_length=128, verbose_name="系统类型") HostPosition = models.CharField(max_length=128, verbose_name="机房位置") HostPlatform = models.CharField(max_length=128, verbose_name="所属平台") HostGroup = models.CharField(max_length=128, verbose_name="分组") HostDataTime = models.DateTimeField(verbose_name="检查日期") HostUser = models.CharField(max_length=64, verbose_name="负责人") hostStats = models.CharField(max_length=1, choices=STATUS_CHOICES, verbose_name="设备状态") def __str__(self): return self.HostName # 用于给本表指定别名,这样前端就不是英文的了 class Meta(): verbose_name = "设备清单" verbose_name_plural = "设备清单" # 设备再用状态 def Status(self): if self.hostStats == 'd': format_td = format_html('<span >在用设备</span>') elif self.hostStats == 'p': format_td = format_html('<span >下线设备</span>') elif self.hostStats == 'w': format_td = format_html('<span >损坏设备</span>') return format_td Status.short_description = "当前状态"# 指定Ping检测结果表class HostPingInfo(models.Model): id = models.AutoField(primary_key=True) HostAddr = models.CharField(max_length=128, verbose_name="主机地址") flage = models.CharField(max_length=64) class Meta(): verbose_name = "存活检测" verbose_name_plural = "存活检测" def Status(self): if self.flage == "True": ret = "已连接" color = "green" return format_html('<span >{}</span>',color,ret,) elif self.flage == "False": ret = "未连接" color = "red" return format_html('<span >{}</span>', color, ret,) Status.short_description = "状态"# 定义CPU/内存利用率数据表结构class HostCPUOrMemInfo(models.Model): id = models.AutoField(primary_key=True) HostAddr = models.CharField(max_length=128, verbose_name="主机地址") Cpu_Count = models.IntegerField() Mem_Count = models.IntegerField() class Meta(): verbose_name = "CPU内存性能" verbose_name_plural = "CPU内存性能" def Cpu_Speed(self): return format_html('<progress max="100" value="{}"></progress>',self.Cpu_Count) def Mem_Speed(self): return format_html('<progress max="100" value="{}"></progress>',self.Mem_Count) def Check(self): return format_html('<a href="/admin/MyWeb/hostdb/{}/change/" rel="external nofollow" >查看</a>',self.id) Cpu_Speed.short_description = "CPU利用率" Mem_Speed.short_description = "Mem利用率"继续定制admin.py并与上方的数据库视图相交互.
from django.contrib import adminfrom MyWeb.models import *# 必须继承ModelAdmin基类,才可以调整参数,HostDB则是你的表的名称@admin.register(HostInfoDB)class MyAdmin(admin.ModelAdmin): admin.site.site_title="后台管理" admin.site.site_header = "自动化监控平台" # list_display = 你需要展示的字段应该写在这里,此处是数据库中的字段 list_display = ("HostAddr","HostName","HostType","HostPosition","HostDataTime","HostPlatform","HostGroup","HostUser","Status") # search_fields = 用于添加一个搜索框,此处作为查询条件 #search_fields = ("HostAddr","HostType","Status",) # list_filter = 设置一个过滤器,此处是过滤条件 list_filter = ("HostAddr","HostGroup",) # ordering = 设置一个排序条件,此处是以id作为排序依据 ordering = ("id",) #list_per_page = 设置每页显示多少条记录,默认是100条 list_per_page = 10 #list_editable = 设置默认可编辑字段 #list_editable = ("HostName",) # date_hierarchy = 显示详细时间分层筛选 date_hierarchy = 'HostDataTime' # readonly_fields = 可以设置只读字段,就是无法修改的字段 #readonly_fields = ("hostCPU","hostMEM",)# 定义Ping检测显示字段@admin.register(HostPingInfo)class MyAdmin(admin.ModelAdmin): list_display = ("HostAddr","flage","Status")# 定义内存CPU利用率字段@admin.register(HostCPUOrMemInfo)class MyAdmin(admin.ModelAdmin): list_display = ("id","HostAddr","Cpu_Count","Cpu_Speed","Mem_Count","Mem_Speed","Check")保存后直接执行命令,完成命令行建表操作.
python manage.py makemigrationspython manage.py migratepython manage.py createsuperuser保存后启动,Django并访问http://127.0.0.1:8000/admin登录后我们依次看一下定制效果.
主页中的展示效果如下.
当我们需要增加自定义动作时,可以这样写,我们以HostCPUOrMemInfo为例
# 定义内存CPU利用率字段@admin.register(HostCPUOrMemInfo)class MyAdmin(admin.ModelAdmin): list_display = ("id","HostAddr","Cpu_Count","Cpu_Speed","Mem_Count","Mem_Speed") # 添加的自定义动作,此处可执行操作 def func(self, request, queryset): # 此处可以写一些执行动作 print(self, request, queryset) func.short_description = "自定义active动作" actions = [func, ] # Action选项都是在页面上方显示 actions_on_top = True # Action选项都是在页面下方显示 actions_on_bottom = False # 是否显示选择个数 actions_selection_counter = True
