1.创建工程simplecmdb
django-admin.py startproject simplecmdb
2.创建应用
cd simplecmdb
python manage.py startapp hostinfo
3.编辑配置文件
vim simplecmdb/setting.py
1 INSTALLED_APPS = ( 2 'django.contrib.admin', 3 'django.contrib.auth', 4 'django.contrib.contenttypes', 5 'django.contrib.sessions', 6 'django.contrib.messages', 7 'django.contrib.staticfiles', 8 'hostinfo' 9 #添加应用10 )11 12 MIDDLEWARE_CLASSES = (13 'django.contrib.sessions.middleware.SessionMiddleware',14 'django.middleware.common.CommonMiddleware',15 # 'django.middleware.csrf.CsrfViewMiddleware',16 #注释csrf方便使用第三方工具curl17 'django.contrib.auth.middleware.AuthenticationMiddleware',18 'django.contrib.messages.middleware.MessageMiddleware',19 'django.middleware.clickjacking.XFrameOptionsMiddleware',20 )
4.添加model
1 from django.db import models 2 3 # Create your models here. 4 5 class Host(models.Model): 6 hostname = models.CharField(max_length=50) 7 ip = models.IPAddressField() 8 vendor = models.CharField(max_length=50) 9 product = models.CharField(max_length=50)10 sn = models.CharField(max_length=50)11 cpu_model = models.CharField(max_length=50)12 cpu_num = models.IntegerField()13 memory = models.CharField(max_length=50)14 osver = models.CharField(max_length=50)
5.初始化数据库
python manage.py sqlall hostinfo
python manage,py syncdb
6.编辑url.py，添加url
url(r'^hostinfo/collect/','hostinfo.views.collect')
7.编辑views.py
1 from django.shortcuts import render 2 from django.http import HttpResponse 3 from hostinfo.models import Host 4 5 # Create your views here. 6 7 def collect(req): 8 if req.POST: 9 hostname = req.POST.get('hostname')10 ip = req.POST.get('ip')11 product = req.POST.get('product')12 sn = req.POST.get('sn')13 vendor = req.POST.get('vendor')14 cpu_model = req.POST.get('cpu_model')15 cpu_num = req.POST.get('cpu_num')16 memory = req.POST.get('memory')17 osver = req.POST.get('osver')18 19 host = Host()20 host.hostname = hostname21 host.ip = ip22 host.product = product23 host.sn = sn24 host.vendor = vendor25 host.cpu_model = cpu_model26 host.cpu_num = cpu_num27 host.memory = memory28 host.osver = osver29 30 host.save()31 32 return HttpResponse('data have save into DB')33 else:34 return HttpResponse('there is no data from POST method') 8.注册model到admin界面
1 from django.contrib import admin 2 from hostinfo.models import Host 3 4 # Register your models here. 5 6 class HostAdmin(admin.ModelAdmin): 7 list_display = [ 8 'hostname', 9 'ip',10 'product',11 'vendor',12 'sn',13 'cpu_model',14 'cpu_num',15 'memory',16 'osver']17 18 admin.site.register(Host,HostAdmin)
9.启动服务
python manage.py runserver 0.0.0.0:8000
10.访问
curl -d hostname='node02' -d ip='192.168.1.2' -d product='BL 380' -d sn='XX213' -d vendor='HP' -d cpu_model='Intel' -d cpu_num=1 -d memory='250G' -d osver='md 05c' http://192.168.1.120:8000/hostinfo/collect/
